Winter Storm Watch Tue-Tue Night

A Winter Storm WATCH has been issued for WNY from Tuesday AM into Wed AM. There is a possibility of heavy snow accumulations in that time period. This morning's 12NAM didn't run properly, so we're running a little short on new guidance. First glance makes me lean a bit toward moderate rather than truly heavy amounts, with the snow picking up in tempo during Tuesday afternoon. More on this a little later, with an updated forecast on News 4 at 5, 5:30 & 6. Mike's forecast from noon can be viewed on wivb.com, right now.

Snow won't start until Tuesday afternoon, so no chance for cancellations Tuesday...will probably be all over by Wednesday morning....be happy with the wind chill day you got today!!

Light snow may arrive before noon, and pick up in tempo during the afternoon, so the PM commute will be impacted--not the AM commute.

Accumulations will tend to run a little higher south and SE of the metro area with this system. There will be warming aloft, so a slight chance of sleet mixing in closer to PA can't be ruled out.

The hitch downward in the NAO has been projected for some time now in the ensembles. But the return to a warm phase NAO is still likely as we get into next week. The PNA is also running a little more Positive (colder for us) for a few days. A weak block is setting up over nrn Greenland, which will allow a Canadian trough to keep us colder most days this week, though Sunday & today will be the coldest by far, with another less impressive cold shot arriving for Friday night-Saturday.

This map version is great to watch over the course of and day and watch the evolution of a storm.

Looks like might be a busy 48 hour for Team Wivb..

Based on current info does it look like its going to be an 6-12 hour event or a 3-6 hour event , as relates to getting alot of snow in short period of time..


PS: I am not asking amounts.. =]

Thank you

NWS said Winter Storm Warning will most likely be placed for all of WNY from tuesday morning to weds. morning. So most likely 6-12 hour event of moderate snowfall falling for a long period of time. No amazing snowfall rates expected, probably an inch per hour max. But total snowfall could exceed 8 inches in spots. So not to bad, perfect amount of snow for snowboarding and snowmobiling this weekend! Cant Wait =). Mary Beth keeps hinting at a storm coming sunday, that may be bigger then this one. Will see though.

Okay. 18z NAM still holding qpf down below Warning criteria, but as NWS said, other factors may outweigh the NAM (12z had problems).

HPC analysis currently going toward the lower end of the range, and is down from their early AM analysis.

Composite radar is showing heavy snow over wrn KY, streaking east--but this moisture will be lifted to the NE. Question will be whether this moisture laden air will reach the 8 WNY counties. Odds sltly higher for higher terrain to the S & SE for this to happen. 00z run, obviously, will help.

February 11, 2008 6:09 PM  
Blogger Don Paul said...

Not to belabor the point, Rich, but the NWS never said they probably would go over to a Warning. They said their current estimates, which were based on incomplete data, would reach Warning criteria if they held together.

In fact, the 18z NAM doesn't support Warning criteria, so the late run will be especially important. And, HPC in DC has downgraded the probabilities of heavy snow in their afternoon run. State College dropped the WS Watch and went w/a Winter Wx Advisory--but that's possibly because IP/Sleet might hold down snow accum in nrn PA (and I can't rule that out for places like Olean & Wellsville, since there's nothing magic about a state boundary.

Mr Don,

kinda reminds me of last winter, now that its cold and snowy in February, just not as much lake effect such as lake storm locust which brought southern and central erie county locally 40 inches and redfield ny 140 inches. Anyway the winters seem to start later for some reason. Maybe one of these years winter goes from november through march and spring begins in april. Last year we went form winter to summer.

Don, Im not sure if you watched Mike's forecasts this morning (5,6,7am) but he was strictly calling for only 1-3 inches of snow for the event on Tuesday. I found that a little perplexing, because both channel 2 and 7 were going with amounts much higher than Mikes. The other two channels were calling for WGRZ 4-6" and WKBW 2-4". NWS in the morning was not putting an exact amount on it, but they said over half a foot is possible. And to think MB was calling for 2-5" of snow for the Tue event the night before on the 11pm news. I wonder what prompted Mike to somewhat "down play" the event, and go with 1-3"??! It had made no sense to me. I know model runs change, and factors also change... but I would really like to know how he came up with 1-3 inches, when it seems like the "data" says otherwords. Just something I noticed, and wanted to ask about.

February 11, 2008 8:52 PM  
Blogger Don Paul said...

The growing season/first & last frost dates for the NE and our region in particular have trended toward shorter winters than in the past, with this trend having become more evident in the late 80s. Even in lengthier winters of the past, most had thaw periods and seldom were consistently cold from November-March.

In this recent trend, there's a higher probability that global warming has a connection--though this is not yet conclusively proven.

Last year's early winter warmth was closely linked to el nino. Conversely, this year's mostly mild (funny to post this in the midst of a strong cold snap)pattern is linked with a vigorous moderate el nino. However, the ensembles show the NAO will be negative for a few days (less so in a few days, and then positive later next week) and the PNA will be cold/positive for a few days.

With L Erie as icy as it is, its lake effect potential has certainly been reduced at this point--but it's not gone.

First of all, alex, 2-4" is not "much higher" than 1-3." Secondly, Mike had additional amts coming in tomorrow night, without a number on it. It's fine for you to speculate about whether or not it made sense to you. What's important is whether or not it made sense to professional meteorologists. In the AM, Mike and Aaron are the only wcasters with b.s. degrees in meteorology. 2-4" can be as little as .1" difference in liquid equivalent. The fact that NWS did NOT put a number on it, and Aaron had a number only slightly higher than Mike's daytime-only number (he DID say add'l accum were possible tomorrow night) should tell you something about scientific uncertainty--which I have written about extensively in an earlier thread.

yada yada yada about bs degrees in a specific field. I go to college, degrees don't give you knowledge. Well very limited at that. Real life experience gives you knowledge. So those with the most experience in my terms is the most knowledgeable about something. Don you've had countless years of experience forecasting weather. You know how to predict it from situations that have occured in the past. But please stop bashing people for questioning the meteorologist, there just statements or questions from us. That is what this board is about. They can question what forecast you made and why, do not bash them for that. I've been following the weather for years, looking at what happens in certain situations and storm tracks, looking at simple forecasts models, etc...We can predict the weather to a degree also, just because we dont have 4 years of college doesnt mean nothing. I know some people that know more about the weather, including myself then some meteorologist. *cough* kevin. =0.

Don, I made a mistake on my post earlier. WKBW was calling for 3-6" in the morning weather cast, not 2-4. I should have re-read my comment before I had posted it. As far as Mike's morning forecast of 1-3" of snow for Tuesday... yes he did talk about snow Tue night, however he said only about an addtl' inch could be expected. If you add that up, Mike was calling for 2-4" total we'll call it. The one thing that was a little "mis leading" was the fact that he said he was going with the lower end of that 1-3" on Tue in the day, when other weather outlets were a bit more than that. Usialy when winter weather events come around in WNY, meteorologists would stress the snowfall amounts, and make sure they do in fact make mention of the up-coming weather event. Mike did not do that in the morning. He flew through the Tue forecast, as if it was no different than any other day... and he did that with every weather cast in the morning, which tells me time was not a factor. When the meteorologist giving the forecast doesnt make much of Tue's weather, than normaly I wouldnt ether. The data in the morning was more "intense" with this upcoming storm, as the day progressed, the models tended to back down somewhat. If you watched Mikes forecast at noon, you would know that he had somewhat of a "wake up call" because you could tell from his expressions and how he gave the forecast. Now, in my mind, he should have been like that in the morning, and he (if he wanted to) could have backed off a bit for the noon cast, due to a change in data. As for your comment "What's important is whether or not it made sense to professional meteorologists." I agree with that, however it is also importiant that the meteorologist presents the forecast in an accurate and understandable way for people who might not be pro meteorologists. Mike usialy does an excellent job at forecasting the weather, that's why I was a bit perplexed this morning and afternoon when I watched his somewhat different weather casts. Who know's... we may end up only getting 2 or 3 inches of snow out of this, and if that's the case... prop's to Mike and his stand-alone forecast. Thanks for answering my previous post Don, and lets hope for a good amount of snow! (I know we both enjoy the snow) Keep up the great work!!

Experience counts for something, but if you don't have a fundamental education in a science, experience generally isn't enough. That's why the NWS hires ONLY degreed mets to forecast the weather, with rigid course requirements (you can look them up on either the NWS or AMS sites). TV is a loosey-goosey kind of medium, and the gift of blarney can carry someone a long way. But when the public safety is at stake in severe weather with the extraordinary complexities of interpreting velocity displays on Doppler radar (as an example), blarney means NOTHing. It takes formal education and training to even begin to use that data and AFTER that training, then experience begins to mean something. Of course, even a credentialed met isn't going to do well in operational meteorology if he or she lacks a passionate interest in the work. It's an uneasy balance.

Rich, not particularly high confidence. Only the GFS has a strong signal for the storm. The European and other global models which go out that far keep us well away from the storm's center. In fact, I changed my wording at 10 & 11 to emphasize "chance" of a general snowfall on Sunday.

February 11, 2008 11:38 PM  
Blogger Don Paul said...

Late evening update: 00z NAM is slower than 18z GFS. Strong ridge of arctic high pressure in place favors this solution, so I pushed the onset of lt snow back to early afternoon, though it will start later in AM in srn tier and mid AM nrn PA. Snow picks up somewhat by late afternoon, w/2-3" by sunset--making for a slick commute.

More frequent periods of snow overnight, but warm air advection aloft may bring sleet/ice pellets into play S/SE of the metro area well inland, holding accum down in those areas. Add'l 2-4" may fall on the Niag Frontier. Another inch or so possible early Wednesday, before the snow pulls off to the east.

Bottom lines: Not a whopper, but enough to make for tricky travel. Will be marginal for meeting hvy snow criteria or winter storm criteria, but could just barely make it. Storm is currently turning out hvy precip streaking across Ky/Tn; still questionable how much will get into far WNY, but NAM has been more consistent last 2 runs. Looks like all snow for most of Niag Frontier, but a slight jog to the NW for this storm would bring more a wintry mix tom'w night.

Wind will definitely not be a factor with this storm, which simplifies things for the road crews.

Hi everyone!
I'm no weather expert, but given the duration of all this expected snowfall, I'm intrigued by the warning and the use of crawlers on TV. This seems like the kind fo snowfall that we typically just shrug off, yet hours in advance many are preparing for the worst because of warning notifications. What I wonder is does anyone else think that the use of the word "warning" to the public is becoming too frequent? Even where I work people are looking at each other saying "a few inches of snow by tonight? So what?" At what point is the NWS just crying wolf in the eyes of "average joe"? Maybe they are in a tough position, because if they don't warn people wonder what they are doing?

If the NWS feels the storm will meet their Winter Storm Warning criteria--and they do at this time--they will issue the Warning, and we are bound to broadcast the warning to the public.

Right now, my feelings are that the storm will only marginally meet these criteria, with 3-4" in the srn tier by evening, and 1-3" further north (least near Lk Ontario), with an additional 2-4" tonight with some sleet arriving later this evening possibly as far north as the metro area. In the srn tier & nrn PA, sleet and freezing rain may become more dominant, and produce more hazardous travel conditions. Another 1-2" will be possible early tomorrow.

If no sleet mixes in, amounts may be a little greater. Sleet is less likely to the N & NW of the Buffalo Stowns.

You can look up the definition of Winter Storm Warning on the NWS Buffalo website.

The warning is not because there is a forecast of 2-4 inches. It is based on certain criteria that must be met in a given period of time. If you go to the NWS website you can view it there. I don't believe it has changed much over the years, so if these same conditions were anticipated 10 years ago they probrably would have issued a storm warning. I did not research this so I may be way off but I have a hunch a winter storm criteria have not changed much.

mark,

I certainly understand your concern about lost commerce. That's why I almost never say "stay home," with a very rare exception being that early evening last week when we had a disastrous ice-up and scads of accidents--in which case I said wait some time to give salters more time to do their work.

The NWS would never issue a Winter Storm Warning for "2-4" of snow alone. That's well beneath their criteria. They are expecting as much as 8" and the possibility of sleet and freezing rain in parts of the region later this evening to complicate matters.

Will this be an awful blast of a storm? I don't think so, but a Warning is only issued when the mets on duty feel the criteria will be met (heavy snow or snow & ice, i.e.)--and "2-4" just wouldn't cut it.

It seems like every "big" storm sounds impressive a couple of days out, and as the date approaches the snowfall totals get smaller and smaller until it ends up being snow with sleet and freezing rain. The 5-8 inches turns into just a few inches with...ugh...sleet and freezing rain (messy and more dangerous for driving IMO). Why does the warm air keep making it up to WNY for nearly all of these storms that could be snow-makers, turning them into wintry mix events?

For larger, more "traditional" snowflakes, there needs to be a fairly deep layer in the clouds with subfreezing temps and abundant moisture for the growth of dendritic snow crystals. Shallower cold air with weak upward motion can lead to the small, sometimes needlelike, sometimes particlelike snow. When the subfreezing layer gets shallower, snow can turn to rain falling thru the warm layer, and then either refreeze into sleet pellets before hitting the ground, or if the subfreezing air is hugging the surface, fall as rain and then freeze into a glaze on contact.

marinecore,

I would not expect power outages from this storm. Some models have the wintry mix making it all the way to the south shore of Lk Ontario. Our Super Microcast has it getting as far north as the Buffalo Ntowns and just north of the Thruway, but Niag & Orl Cos staying as all snow. Where it stays as all snow, snow totals would likely exceed my current projected range of 3-5" add'l tonight. Lesser amts of snow seem likely where the changeover occurs more quickly, as per the srn tier and nrn PA.

I'll be looking at the balloon soundings & sfc observations closely this evening, along with the 00z NAM run and the next run of our Super Microcast.

Don...will the snow from this storm ever become truly "heavy", or will we continue with the steady, but relatively light snowfall we are experiencing right now...I know variables such as location and mixing will enter into this...I'm located on the West Seneca/Orchard Park border...what's the latest analysis...thanks

I doubt the rate of snowfall will become truly heavy (vis <1/4 mi). As I've already posted, it's the combination of significant snow accumulations followed by an icy mix which has likely factored into the NWS' decision to keep this as a WS Warning.

JUST THOUGHT I'D LET ALL IDEA contributors to our Buffalo Weather Experience Center (BWEC) thread from a few weeks back that your ideas have been viewed by member of the Steering and Exhibits Committee. We continue to make steady progress in laying down the foundation to make this amazing project a reality on our Waterfront.

If you have more ideas--keep 'em coming! (preferably on that thread so committee members and advisors can find them all in one convenient location on the Blog)

Thanks again,

Don Paul

Snowfall rate has increased to what I would describe as moderate now in West Seneca...I also see the dry patch approaching on radar...but right now its positioned down around Jamestown...still probably a good couple of hours before it reaches us....Don...how long will the duration of icing last here in West Seneca once it begins?...just trying to get a handle on how much extra time will be needed in the morning...thanks

Does anyone think that schools could possibly be cancelled tomorrow? I know meteorologists to make that call but I was just wondering...

snow day: at first i thought probably not but because the freezing rain has started already roads will be very icy. It's a 40/60 chance. i still think school will be on though.

Thanks for all the updates, folks! Composite mosaic radar (w/precip-type colors) are not nearly as accurate as ground truth, since the algorithms only produce approximations.

We appreciate you letting us know what's going on in your towns.

hamburgsnowman,

Before I go back to work, I have to tell you your humidity gauge is way too low. Should be closer to 90% right now.

Freezing rain here in Amherst too. I didn't expect it to come so early in the evening! We could get substantial icing from this.

This weather system should have drawn nothing more than a winter weather advisory. Looks like Don and Mary Beth over dramatized yet another winter weather event.

Hey Don:

When's it gonna warm up?

Hey last anonymous--First of all, we don't determine whether or not it's an Advisory or a Warning. Obviously, you're not too swift on that particular topic--nor on the rapidly deteriorating conditions currently developing in freezing rain.

There--that felt better!

Pretty steady freezing rain here in South Wales now. I hope it doesn't last too long.

Last Anonymous: With all due respect, you're way off the mark with your claim. I clearly did not "over-dramatize" this winter weather event. I called for 2-5" on back on Sunday....and driving is certainly tricky tonight. Don was on the money, too!

Anonymous you know absolutely nothing. The NWS issues the warnings, advisories, etc..Not Don. You proved no point besides ur pathetic stupidity. The conditions outside right now are in criteria for Winter Storm Warning. We got 2-3 inches of snow, now already got alot of freezing rain out there and it doesnt look like that will stop for awhile. Maybe a quarter inch of freezing rain is criteria for Winter Storm Warning.

No more winter storm warning for WNY. It is now an advisory until 11am Wednesday.

Ok... Mr. anonymous, you can go post on the blog for losers... your obv in the wrong place! Im going to guess your an over excited little kid who snuck past mom and dad to get on the computer to post your awesome knowledge on the weather. This is not the place for you! If you want to bash Don and MB... go ahead, but it only shows how much of a loser you are Mr. ananymous who wont even post with a real name! Go to bed, you have school tomorrow!

It's a shame that there is so much immaturity on this weather blog. Don and MB downplayed this event even when others were doing the opposite. Who was closer to the truth? Don't listen to the pathetic ramblings, WIVB mets. Great job doing a job that is not black and white.
