WHAT HAS CHANGED

Heat Advisory issued for the entire area Thursday and Friday.

KEY MESSAGES

1. Very warm and humid through the weekend, possibly lingering into the start of next week.

2. Potential for mainly afternoon/early evening heavy downpours through Saturday.

KEY MESSAGE 2

Along with the very warm and humid airmass will come the chance of showers and thunderstorms. The airmass will gradually destabilize over the next couple of days with disturbances in the SW flow aloft. The best chance will be during the afternoon and evening hours, mainly for NYC and points north and west. Friday has the potential to be a more widespread event. Heavy downpours are likely with any showers and thunderstorms with high PW values around 2 inches. Isolated pulse severe storms can't be ruled out, but wind shear and mid-level lapse rates are weak. WPC has much of the area under a marginal risk for excessive rainfall Thursday and Friday. This is for isolated instances of flash flooding.

Thursday Afternoon-Night: Mainly VFR with chance of MVFR and showers/storms in afternoon and evening, especially N and W of NYC metros.

Friday: Showers and thunderstorms likely in the afternoon and evening, especially in the vicinity of NYC metros on N and W.
