Frigid Weekend. Storm Risk Tuesday

 

Good Evening from chief meteorologist Tony Petrarca…

After several inches of wet snow, most of which accumulated everywhere but the pavement, we set the stage for frigid air to work in. Temperatures will begin to tumble overnight along with increasing winds.  Infact wind chills will be a significant Saturday ranging form -5 to +5.  Actual air temps Saturday will only be in the mid 20s.  Frigid air Saturday night will extend thru Sunday and Monday.

WHAT FELL TODAY (reports from National Weather Service)

TEMPERATURES SATURDAY…FRIGID

All the buzz has been about a coastal storm late Monday night into Tuesday.  At this point there is  high confidence that a storm will infact form off  the Mid-Atlantic and New England and intensify rapidly.  Multiple computer models are averaged out (see map below) each day,  and they continue to show intense low pressure  (green circle) developing off coast

So while the big weather picture is coming more into focus Tonight, it’s the finer details that have not been resolved yet (we are still 3-4 days out). Most importantly is the storm track and duration. Seeing indications it may be a slow mover.  While cold air will be in place for snow, a track too close to the coast or to our west (inland) could briefly pull in enough mild air for snow to mix with rain near the coast.

 A track just offshore about 100 miles south of Nantucket would put our area on the cold and snowy side along with powerful winds.  Wind gusts of 50-70 mph along and off the New England coast combined with very heavy snow would make this a classic Nor’easter with near blizzard conditions (BUT, only if certain weather parameters come together).  Again its still early… we don’t know yet if blizzard conditions will happen,  but the chance is there.

Check back with me Tonight at 10PM on FOX and 11pm WPRI channel 12 for updates. Tune into TJ this weekend and certainly keep it here at WPRI.com and our blog page for the latest:

Lets point out some early thoughts

 TIME FRAME:  Late Monday night and especially all of Tuesday

 OCEAN: Large waves, potential coastal flooding

 WINDS:  Gusts 50-70 mph along coast and offshore

 PRECIPITATION: Significant amounts of snow inland (potential  transition to rain then back to snow)

 IMPACT AREA:  Large area, from New Jersey to coastal Maine
