WHAT HAS CHANGED

With thunderstorms pushing east, the Severe Thunderstorm Watch has been cancelled everywhere except Long Island and southeastern CT.

The showers and thunderstorms have allowed temperatures to decrease, allowing for the cancellation of the Heat Advisory.

KEY MESSAGES

1) Unsettled with periods of showers expected for the upcoming holiday weekend along with a much cooler airmass over the region.

KEY MESSAGE 1

The end of the week will remain dry and much cooler. The dry period will be short-lived as unsettled weather with periods of showers looks likely for the upcoming holiday weekend. The frontal boundary that moves through today/Wednesday will remain to our south with multiple disturbances/waves of low pressure moving along it through the weekend. Moisture from these systems will overrun high pressure to our north and east.

The main challenge for this period is timing when the most widespread shower activity will occur. The highest probabilities currently are from late Friday through early Sunday. However, there is still some uncertainty, especially if the surface ridging from the high is stronger. This would help suppress the showers a bit further south, with at least the northern half of the region seeing less rainfall. Chances for showers continue late Sunday into Memorial Day as additional energy may pass to west or northwest.

Otherwise, will remain mostly cloudy through the weekend with temperatures likely running below normal for late May in the low to mid 60s. Nighttime temperatures should be in the 50s. The frontal boundary may get pushed further south by next Tuesday, which could help lower any chance for showers.

OUTLOOK FOR 00Z FRIDAY THROUGH MONDAY

Thursday Night: Mainly VFR.

Friday: Possible showers and MVFR conditions late at night.

Saturday: MVFR or lower with showers. E-NE wind gusts 15-20 kt.

Sunday: MVFR or lower with showers. E-NE wind gusts 15-20 kt during the day.

Monday: Chance of MVFR or lower with showers.

MARINE

A Small Craft Advisory over ocean waters has been expired early. Waves are below 5 ft. Its possible waves could return above 5 ft with the front and any stronger showers or thunderstorms this evening into early tonight. However, should this occur, it would likely be too brief and local for a widespread SCA issuance.

Winds and waves will remain below SCA levels through Saturday morning. Saturday morning into Sunday winds and waves may once again reach SCA levels, while waves on ocean waters could remain elevated into the start of next week.
