Improving Pattern after Saturday

An approaching cold front will set off more numerous Showers & Tshowers mainly later on Saturday and early Saturday evening. Drier and cooler weather will settle in for Sunday, with any light shwrs ending early, clouds thinning, and more sunshine returning for the afternoon. Saturday's tstorms are unlikely to produce severe weather. Since the instability ahead of the cold front will be surface-based, rather than elevated (in which there is little connection with the air near the surface), Lake Erie's chilly waters may weaken approaching convective cells to some extent. Upper level winds will also not be conducive to producing severe weather. The cooling behind the cold front will take Sunday's highs back to the mid 50s, which is not the kind of chill we had earlier this past week.

Cold Spell Won't Last Too Long...

but while it's here, it will still bring a threat to tender vegetation during the nightime hours. Of course, knowledgeable gardeners would presumably know better than to put out tender plants this soon. But many trees and plants are at an advanced state of blooming, and may face some limited damage potential. The amount of nightime cloudiness will make all the difference as to the threat of frost (no threat when it's overcast) and freezing. It does appears some srn tier/rural areas will face a freeze potential Tue and Wed nights. Temps will begin to moderate on Thursday and especially on Friday into the weekend, but a warm front to our south may produce a few showers. The weekend looks fairly mild but unsettled at this early point.
