NYC Weather Update – May 21, 2019

This week kicked off with high temperatures yesterday that were more typical of the mid-summer. Things have cooled off noticeably this morning in the wake of a cold front that brought some showers and thunderstorms to parts of the region last night. The remainder of the week should see temperatures around normal for this time of year, with the next chance for rain Thursday. Looking ahead to Memorial Day weekend, it seems there could be some rain chances especially late Saturday into Sunday.

Rest of today – sunny conditions with high pressure in control today. Fresh northwesterly breezes calming down later in the afternoon. High temperatures in the low-70s. Overnight lows in the mid-50s.

Wednesday – high pressure remains in place, yielding another great day with lots of sun and seasonable high temperatures in the low-70s. Overnight lows in the upper-50s as a warm front approaches from the southwest.

Thursday – chance for showers, on the light side developing ahead of this approaching warm front. High temperatures in the low-70s with partly sunny skies. Rain chances increase going into the overnight hours as the parent low of the warm front nears, lows in the low-60s.
