Hot and humid conditions will couple with upper atmospheric support for thunderstorms this afternoon.
Sunday will feel very similar to Saturday, but it will likely not get quite as warm thanks to clouds and developing thunderstorms.
The main difference between today, when storms are expected to be fairly numerous and widespread, and yesterday, when there were only a couple, is in the upper levels of the atmosphere.
Yesterday, there was no support for thunderstorms to generate. Without a trigger and without the support of the upper atmosphere, only isolated storms popped up.
Today, the upper levels of the atmosphere are more conducive to storm development as pressures fall ahead of a cold front. With the very high levels of heat and humidity, thunderstorms should have little trouble firing up later. Already, a few showers are trying to develop across the heart of the Finger Lakes.
Storms will become more numerous this afternoon. A few places may still mostly miss out on the rain, but quite a few more places will see at least some rain. Locally heavy rain is also possible thanks to the thunderstorms.
Severe weather is generally not expected today. A few storms could briefly get strong and produce some gusty winds or even small hail. The winds throughout the atmosphere will be too weak to support significant, widespread or sustained severe threats.
Thunderstorms will transition to showers tonight and into Monday morning as the cold front approaches. The front should move through during the morning on Memorial Day, leaving the area with a pleasant afternoon. Showers should move east and temperatures will top out near 80 degrees.
Most of next week looks quiet and comfortable. A cold front will move through Thursday night with some rain. Ahead of that front, temperatures will jump back into the 80s, but the remainder of the time we should enjoy 70s for highs.
