SATURDAY COULD BE A SOAKER FOR LONG ISLAND

After a bright sunny start to the day, clouds have taken over on this Friday afternoon. Rain is on the way for Saturday. Expect showers to develop as the leading edge of the storm system moves in during the early morning hours tomorrow. As the center of low pressure passes by during the afternoon, Long Island could be looking at some downpours. NOAA’s Weather Prediction Center puts Long Island under a marginal risk for excessive rainfall, which means minor flash flooding is possible.

EXCESSIVE RAINFALL PROBABILITY

With this heavy rain possible during the afternoon, most spots of the island could pick up over an inch. Also, as the pressure gradient tightens, it will become quite breezy throughout the day. That gusty southerly flow could push some more water ashore, and so a coastal flood statement has been issued for both the north and south shores of Nassau and western Suffolk tomorrow morning. The rain wraps up on Saturday evening and we salvage the weekend with a mostly sunny and breezy day on Sunday. Monday remains dry as well but rain returns on Tuesday, That rain could begin as a wintry mix should it begin during the overnight hours.  Looking at the sounding below, we can see a saturated atmosphere (red temperature line and green dew point  line intersecting) and temperatures just above the ground below freezing.

ATMOSPHERIC SOUNDING FOR EARLY TUESDAY MORNING

As we look further down the road, much colder air looks to settle in late next week, which once again will put us on snow watch. But until then, 2019 begins how 2018 left off: wet and mild!   –Geoff Make sure to follow Meteorologists Geoff Bansen and Joe Cioffi on social media!
