Hot & Humid: Advisories In Effect Across The Hudson Valley

HUDSON VALLEY, NY — Back-to-school week in the Hudson Valley is starting with heat index values in the mid to upper 90s, and the National Weather Service has issued heat advisories.

For Orange, Rockland and southern Westchester counties, a single advisory stretches from 11 p.m. Tuesday morning to 8 p.m. Wednesday.

For western Dutchess and eastern Ulster, an advisory is from noon to 7 p.m. Tuesday.

Putnam and northern Westchester have no advisories.

Hot and humid conditions will continue on Wednesday and Thursday where additional heat advisory headlines will likely be needed, the NWS warned.

In addition, there is a chance of thunderstorms Thursday through Sunday, mainly during the afternoon and early evening hours. A few severe thunderstorms may be possible west of the Hudson River Valley Thursday afternoon into the early evening.

"Thursday may be our hottest day of the summer," Bruce Furbeck of First Due Weather said on Facebook. "It will feel junglelike during Thursday before thunderstorms arrive. Periods with moderate to heavy rainfall are possible later this week and this weekend."

Plus, put away the blankets you got out last week — temperatures won't be getting that low at night.
