Discussion started by cwwright 4 years ago

Mid-Atlantic Region(KPHL,KBWI,KDCA)

This will be an all rain event as temperatures will be way above freezing as pictured below.

 

Light rain will begin to develop around 2pm, and will remain light until a squall line associated with the cold front comes through the region this evening. This is when thunderstorms will be possible with heavy rainfall and strong wind capable of producing wind gust to 50 mph.

 

Rainfall amounts will be light with amounts generally around a quarter of an inch.

After the passage of the cold front temperatures will start to fall like a rock and bottom out in the teens and low twenties towards tomorrow morning.

 

 

NYC Metro Region(KNYC,KISP,KPOU,KBDR)

This storm system will be mostly rain, with some snowfall on the back end depending on how quickly the cold air wraps in and if there is enough moisture. Areas north and west of KNYC will stand the best chance at seeing some snow as they will have more moisture to work with.

 

For the beginning of the storm everyone will start as rain around 2 pm as temperatures are above freezing, and rising in the fifties for coastal sections and in the forties for the Hudson Valley.

 

Precipitation amounts will range from a quarter to as much as a half inch for the city and Long Island with the Hudson Valley approaching three quarters of an inch of pure rainfall.

As colder air works in as the storm departs any rain will change over to light snow and there will be minor accumulations away from the coast generally north and west of NYC of about an inch or two.

 

For coastal areas watch out for flash freezing as any standing water will freeze by tomorrow morning with rapidly falling temperatures.

 

Upstate New York/New England(KALB,KSYR,KBOS)

The city of Boston will see mainly a rain event. As colder air works into the system the rain will change over to some snow.Rainfall amounts will range from a half of an inch to slightly more.

36

 

 

As the colder air works in around look for the rain to change to snow and accumulate generally an inch or two.

 

 

 **freezing rain will change to snow in the next few hours as colder air works in look for snowfall accumulations in the range of 3-6 inches for the Albany area**.

 

For areas north and northeast of Albany(Syracuse, Buffalo, Burlington) this is where temperatures will be below freezing for the entire event, and accumulations of snow could range nearly two feet
