NYC Weekend Weather – May 31, 2019

We’ll get a much needed respite from deluging rains at least for part of the weekend as high pressure initially takes hold of the weather. This should give us two days to start with slightly above average warmth and mostly sunny skies. By Sunday, the next storm system to affect the region will be closing in and we can expect more rain and thunderstorm chances. Timing of this system now appears to clear the area by Monday and result in cooler but sunny conditions starting next week.

Rest of today – early fog has burned off and we’re in line to have a nice day with sunny skies and high temperatures topping out in the low-80s except at the immediate coast where a sea breeze is expected to develop with onshore flow forecast later in the day. Overnight lows in the low-60s.

Weather Prediction Center surface forecast for 8AM Saturday

Saturday – another great day with temperatures in the low-80s (except again at the coasts with sea breezes) and mostly sunny skies. Clouds on the increase late and overnight with lows again in the low-60s.

NAM (North American Model) output for 500 mb vorticity and heights on Sunday 8PM showing a pronounced upper low over James Bay in Canada with a trough extending into the Ohio Valley. This will provide upper level divergence and instability to spur storms on Sunday.

Sunday – a warm front is forecast to push through overnight into Sunday and set the stage for rain and thunderstorms later in the day as a cold front approaches from the west. Temps probably topping out a touch cooler in the upper-70s with more clouds hanging around. Overnight lows around 60°F.

Monday – at this time, expecting the aforementioned cold front to sweep through the region before the day Monday. That should result in cooler highs in the low-70s with mostly sunny skies. Overnight lows in the upper-50s.
