End of heat in sight for FLX

The late season heat wave that has been baking the Finger Lakes will finally break Wednesday evening thanks to a cold front.
The late season heat wave that has been baking the Finger Lakes will finally break Wednesday evening thanks to a cold front.

The hottest, most intense part of the summer waited for early September, but will soon ease up on the Finger Lakes.

A cold front will push through the region on Wednesday evening, ending the most intense heat wave in the Finger Lakes since 2013. Until it does though, Tuesday and Wednesday afternoon will once again be hot and humid.

Tuesday will be very similar to Monday’s weather, with plenty of sun, a few clouds, and temperatures reaching and exceeding 90 degree in many places. With the humidity factored in, it will feel more like the mid to even upper 90s.

The difference between Tuesday and Monday is a slight chance for a shower or thunderstorm. A warm front extends east across the Great Lakes from low pressure associated with the cold front over the Midwest. This may be just enough of a boundary to pop a late afternoon shower or storm, especially near the eastern half of Lake Ontario. The best chance for rain will be approximately from Rochester to Syracuse to Watertown.

Wednesday will be quite warm as well, but with extra cloud cover and some showers and  thunderstorms, temperatures will probably fail to reach 90 degrees in most locations. Still, highs will be in the mid and upper 80s outside of any rain. With the front still far enough to the northwest, Wednesday will not be a washout, with more scattered precipitation expected and a higher chance further west.

The front will cross the region Wednesday night with some showers. Unfortunately, substantial rain may be hard to come by across most of the Finger Lakes before the front stalls out to our southeast. More significant rain is expected Thursday across southeastern New York, but it looks like the Finger Lakes will stay mostly dry on Thursday, with much cooler temperatures generally around 70 degrees.
