NYC Weekend Weather – Apr 26, 2019

A wet start to the weekend this Friday with multiple rounds of rain moving through. Saturday shapes up to be a better day at least in terms of being dry. A second disturbance/low moves through Sunday bringing yet more chances for rain before skies clear up to start next week. Temperatures behind this second storm/cold front will be below normal for this time of year.

Rest of today – periods of rain during the afternoon as a warm front works its way across the area. Some thunderstorms possible. Second round of more focused/heavier rain later in the evening around 7-8PM as a trailing cold front pushes through. This front will have decent upper level support with some indications of a vorticity maxima at 500 mb and us being in the exit region of a 300 mb jet streak. High temperatures today topping out around the upper-50s even with the rain as we’re expected some time in the warm sector of the low bringing us this stormy weather. If the warm front below fails to push north through here though, we may only see temps in the mid-50s. Overnight lows should bottom out around 50°F.

Weather Prediction Center’s most recent surface analysis, showing a marked warm front south of NYC. Some thunderstorms and showers have popped up ahead of this frontal boundary due to isentropic lift (overrunning) as warm air from the south slides over colder air at the surface further nort

Saturday – with the trailing cold front clearing the area tonight, precipitation should end and Saturday should end up being a decent day though with more clouds than sun. High temperatures should be able to get into the low-60s, edging into the mid-60s if more sun breaks out. Overnight lows noticeably cooler with a colder, drier airmass behind today’s cold front, in the mid-40s.

Sunday – a second low approaches from the Ohio Valley, again bringing some potential for rain. This rain is expected to be on the lighter side. Temperatures should reach into the upper-50s. Overnight lows in the low-40s.

Monnday – start of next week should be sunny, with Sunday’s storm system moving offshore. High temperatures will be below normal though, with the cold front associated with Sunday’s low bringing a reinforcing shot of cooler air. High temperatures probably topping out in the upper-50s. Overnight lows in the mid-40s.
