The time frame for the multi-threat, complex system is from late Wednesday night, Nov. 20, into Friday, Nov. 22.
The first image above shows the broad area where snowfall is expected, with 6 to 12 inches predicted in areas shown in the darkest shade of blue.
According to the National Weather Service, Wednesday will be partly sunny with high temperatures in the mid-50s ahead of the system's arrival.
Precipitation will arrive from west to east late Wednesday night. Thunderstorms will become possible starting in the early morning hours on Thursday, Nov. 21. Some of the storms could produce heavy rainfall.
About three-quarters to an inch of rain is expected by around daybreak on Thursday.
The storm's height will kick in Thursday with rain, showers, and more thunderstorms in spots. It will bring the first soaking rain to much of the Northeast since late September.
It will be a raw and blustery day with a high temperature of around 50 degrees, wind speeds of 15 miles per hour, and gusts as high as 30 mph.
New precipitation totals of an inch or 2 inches of rain are expected on Thursday.
Strong wind gusts of 25 mph will continue Thursday night, and those areas where snowfall is expected will see it on the back end of the system at that time.
Friday will be mostly cloudy and colder, with a high temperature in the low 40s. There could be lingering showers during the day and again at night.
It will remain brisk on Saturday, Nov. 23, with a high temperature in the upper 60s and partly sunny skies.
