Map Created: January 23, 2010
Time Period: January 24-25, 2010
Precipitation Type: Rain
Storm set up: A storm moving well to our north and west will draw in unseasonably warm air before its cold front passes through the area with heavy rain and thunderstorms, ending the mild pattern.
Details: Overnight on Sunday, the storm should have a well organized strong cold front, with heavy rain and some thunderstorms. This heavy rain line will then move through the Northeast overnight, with the heaviest rain falling along and west of Interstate 95. The only areas to see any wintry precipitation out of this will be northern Maine, and that also won’t be in big amounts. Temperatures will meanwhile rise into the 60s for Virginia and Washington DC, and the 50s further north except for western Pennsylvania, and northern New York, New Hampshire, Vermont and Maine. It could also be windy at times. After the cold front exits, it will start turning colder, with temperatures dropping. Northern parts of the Northeast could end with a rain/snow mix.
Forecast for NYC Tri-State Area: Heavy rain will start on Sunday night with thunderstorms also possible, ending by Monday late morning. Rainfall totals of 1.5 to 2.5 inches are possible.
