JAMESTOWN – It was a warm and muggy Sunday, and that heat and humidity will continue for our Monday, with scattered afternoon and evening showers and storms.
***Severe Thunderstorm Watch issued for much of Western New York, excluding Chautauqua, Cattaraugus, and Allegany Counties, until 8:00 PM this evening***
The tropical-like air mass remains parked over Western New York this afternoon, with very warm temperatures in the upper 80 to lower 90s, and very muggy conditions. Dew Point values, which is a measure of the moisture content in the air, will be running in the 70s, creating a very sticky, and down-right nasty feel to the air. That will likely spike “Feels Like” temperatures in the lower to mid 90s for the afternoon.
Of course with this kind of airmass in place, it’s that same ol’ song and dance; widely scattered afternoon showers and storms. These storms will popup at random times throughout the afternoon hours, and they could pack a punch.
The Storm Prediction Center has much of Western New York under a standard “Slight” risk (2/5) for severe thunderstorms this afternoon, with the main threats being gusty winds and heavy rainfall.
A cold front will move through the region later this evening, and that will drop our temperatures and humidity to a more comfortable level. However, a band of showers and storms will accompany behind that front, and some of those storms could contain some torrential rainfall, leading to some localized flash flooding.
