Key message 1

The driest stretch of the year so far persists for the next several days.

Surface high pressure centered to our south and east weakens tonight ahead a moisture starved cold front approaching from the west. Cloud cover increases overnight ahead of the boundary, but conditions remain dry and skies clear by early afternoon once it passes through. Winds also veer NW post frontal Friday afternoon and could be noticeably blustery at times, with occasional gusts up to 25-30 mph.

Behind the fropa, dry, cooler conditions settle in for the weekend. Temperatures on Friday remain slightly above normal, with highs in the 60s to around 70 and lows mainly in the 50s. Saturday will be cooler and afternoon highs fall back in the upper 50s and low 60s, with evening temperatures in the 40s and upper 30s outside of NYC. Frost is possible Saturday night outside the NYC metro.

Guidance continues to keep dry conditions in place through early next week. Conditions may begin to turn more unsettled by mid to late next week.

Key message 2

The combination of sufficiently dry fuels, gusty NW winds 20 to 30 mph and relatively low RH values behind a cold frontal passage will lead to an elevated risk of fire spread for parts of the area Friday afternoon.

In collaboration with state partners and neighboring forecast offices, have hoisted a Special Weather Statement for southern Connecticut and the Lower Hudson Valley to highlight this threat from 11am to 6pm Friday.

Winds remain from the SW but lighten a bit Thursday night, then turn to the W and NW into Friday and increase to 10 to 20 kt sustained with gusts up to 20 kt by late morning, increasing to 20 to 25 kt possible by the early afternoon.
