Wednesday Discussion : Heat, Humidity & Sct Afternoon T’storms

Another hot day with more humidity than yesterday is expected today across the Hudson Valley. Highs in the upper 80s, approaching 90° along with dew points in the low 70s will result in an uncomfortable air mass. Heat indexes will range anywhere between 90-95° in valley locations. The Catskills will remain slightly cooler with highs in the mid-80s.

Below are projected heat indexes at 4 pm today:

After a few showers late last night into early this morning, breaks of sunshine are expected, which will help further destabilize an already buoyant atmosphere, setting the stage for scattered afternoon thunderstorms. A few storms may be severe with heavy rainfall and strong gusty winds being the main threats. Current model guidance suggests storms will begin to move into western locations between 3-5 pm and will evolve eastward throughout the remainder of the afternoon and evening. The Storm Prediction Center has placed our entire region in a slight risk (level 2 out of 5) for severe thunderstorms. While not everyone will experience severe weather today, always remember to stay weather aware.

Unfortunately, mugginess and unsettled weather will continue on Thursday, with another chance of afternoon/evening storms.

Below is a simulated radar for this afternoon/evening (1-11 pm):
