2) Frost-Freeze conditions likely outside of NYC/NJ metro Saturday Night into Sunday AM. Otherwise, dry conditions persist through at least early next week.

Key message 1

The combination of sufficiently dry fuels, gusty NW winds 25 to 35 mph and relatively low RH values behind a cold frontal passage this morning will lead to an elevated risk of fire spread, particularly for Lower Hudson valley and southern CT this afternoon.

In collaboration with state partners and neighboring forecast offices, a Special Weather Statement for southern Connecticut and the Lower Hudson Valley remains to highlight this threat thru 6 PM today.

Key message 2

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

Highs today will reach the mid 60s to low 70s before a cold front passes by midday into early afternoon. The cold front will be dry with only brief increasing clouds into the morning, clearing into the evening. Following the front, winds veer NW with gusts 25-35 mph this afternoon into the first half of tonight.

Behind the fropa, dry, cooler conditions settle in for the weekend. Saturday will be cooler as afternoon highs fall back in the upper 50s/lower 60s, with evening temperatures in the 40s and upper 30s outside of NYC.

Overnight lows Saturday night will likely drop into the mid/low 40s in the NYC metro/Nassau, then into the 30s elsewhere. Although some interior spots and the LI Pine Barrens will likely drop below freezing as winds drop off under clear skies allowing for efficient radiational cooling. Frost-freeze conditions are likely Saturday night outside the NYC metro.

Guidance continues to keep dry conditions in place through early next week with temperatures gradually warming each day. Conditions may begin to turn more unsettled by mid to late next week.
