Flooding threat returns to FLX Tuesday

Slow moving thunderstorms with very heavy rain will be possible Tuesday afternoon and could cause areas of flash flooding once again in the Finger Lakes.
Slow moving thunderstorms with very heavy rain will be possible Tuesday afternoon and could cause areas of flash flooding once again in the Finger Lakes.

Flash flood watches have been issued for the western FLX and additional watches may be issued for the remainder of the region this morning.

Low pressure over Michigan will slowly track east, crossing the region tonight. Ahead of this low, a very moist air mass has set up across central and western New York. As the low and its cold front push east, showers and thunderstorms will develop across the area.

These showers and storms are not expected to contain severe weather, with little in the way of instability and very light winds aloft. The small amounts of instability there are, however, will be favorable for some isolated thunderstorms to develop. The light winds will cause the storms to move slowly or even stall out for a time.

The recent dry weather has certainly helped reduce our flash flood potential, but with the slow moving nature of today’s storms, there will still likely be pockets that see flooding problems.

The National Weather Service in Buffalo has issued flash flood watches for the counties in its jurisdiction. Binghamton may follow suit this morning and hoist flash flood watches for the remainder of the Finger Lakes.

The rain threat will continue into this evening before finally pulling out overnight. Another small stretch of dry weather will follow, with the next chances for rain holding off until late Friday or Friday night.
