WHAT HAS CHANGED

Severe Thunderstorm Watch has been issued for NYC metro, NE NJ, Lower Hudson Valley, Fairfield, and Nassau County until 9 pm.

Heat Advisory has been extended through 8pm Saturday for coastal CT and Southern Westchester. No additional changes to the heat advisory have been made.

KEY MESSAGES

1) Hot & humid conditions persist through at least Saturday. The heat will continue into Sunday and Monday, but lower humidity will reduce most high heat index concerns.

2) Scattered showers and thunderstorms this afternoon and evening will bring the risk for isolated to scattered instances of damaging winds and isolated heavy downpours/flash flooding.

3) Chances for showers and thunderstorms continue most afternoons/evenings through the middle of next week.

KEY MESSAGE 3

Saturday into Tuesday, the flow aloft becomes more zonal. During this period, several shortwaves embedded in the zonal flow aloft with bring through numerous surface troughs or quasi-cold fronts. These will support more daily rain chances for afternoons and evenings most days into the beginning of next week. The only exception is Sunday which appears drier. Coverage in showers and thunderstorms each day will vary, but for now we're not anticipating concern for severe weather. WPC carries another marginal ERO for northern interior sections of the CWA on Saturday.

OUTLOOK FOR 18Z SATURDAY THROUGH WEDNESDAY

Saturday Afternoon-Night: Mainly VFR. Chance of showers and thunderstorms in the afternoon and evening. SW gusts 15-20 kt possible in the afternoon.

Sunday-Monday: VFR. Isolated shower/thunderstorm possible well NW of NYC terminals Monday evening.

Sub-SCA conditions continue Sunday into mid week next week.
