Hudson Valley Heat Index Projections Top 100 Degrees: NWS

HUDSON VALLEY, NY — Hot and humid and dirty air, that's what we've got for the end of the work week in the Hudson Valley. The temperatures will be in the 90s but it'll feel much worse, with heat advisories out and an air quality alert from 11 a.m. to 11 p.m.

How oppressive are we expecting? Here are two examples: the Nyack Farmers Market will shut down at noon and Pleasantville Village Hall will be closed from 12-2 p.m. Thursday.

Things will become barely less oppressive on Friday, the National Weather Service said — just look at Poughkeepsie, where the heat index drops from 102 to 101, or White Plains, where it drops from 101 to 98.

"Even if temperatures are slightly lower than Thursday, the combination of heat and humidity will still make for a very uncomfortable day, particularly for those who are working or exercising outdoors and for indoor places that lack air conditioning," said Ryan Adamson, AccuWeather meteorologist.

Still, the actual temperature will drop from high to low 90s on Friday, and the chance of precipitation is up to 60 percent, in the form of thunderstorms and showers in the evening. Not a lot of rain is expected, though - maybe a tenth to a quarter of an inch.

On Saturday temps will inch down and there will be another chance for rain.

Into next week, temps will be in the low 90s. Will it feel balmy? Let us know.
