Strong cold front to bring rain, thunderstorms, late tonight and Saturday
The persistent cloud-cover over much of the region during the past several days finally broke today, leading to a beautiful fall day. However, as the evening progresses, clouds will be on the increase due to a strong low pressure system in Ontario, Canada, and its associated strong cold frontal boundary dragging to its south. These features will be moving eastward throughout the night and approach our area during the day tomorrow.
Today’s NAM Model valid for 2:00pm tomorrow afternoon shows the strong cold front crossing our area, with much colder 850mb temperatures about to move in.
Fortunately, for people going out tonight, any rain should hold off until midnight or slightly later for western sections, and after 2:00am for NYC and east. Plus, given that we are still on the warm side of the cold front, temperatures will not be all that chilly tonight, with lows around 60.
7:00pm: Mostly cloudy skies, temperatures in the low to mid 60s.
10:00pm: Cloudy skies, temperatures in the low 60s.
Midnight: Cloudy skies, temperatures in the low 60s. A 30% chance of showers for western zones, with only about a 10% chance of showers for NYC and east.
2:00am: A 60% chance of rain for western zones, with a 30% chance of rain for NYC and east, and temperatures around 60.
4:00am: An 80% chance of rain for western zones with a rumble of thunder possible, and a 60% chance of rain for NYC and east, with temperatures around 60.
