Thursday Night Update: Surprise Snowstorm Tonight

Well, just in time for February we got more winter weather on tap tonight. A frontal boundary that was originally supposed to stay offshore has trended west. That means snow! Here is what to expect tonight:

• Rain enters the area late tonight
• Cold air quickly crashes in from west to east
• Western counties of NJ changeover to snow first, then areas closer to the coast by around day break.
• The storm will have to overcome the warm air at the surface which will take some time
• However, I expect it will start snowing hard enough for ALL areas to see accumulations from this on grassy surfaces.
• Elevations over 600ft will see roads become snow covered quickly
• Areas at lower elevations will see some road impacts but treated surfaces should make out ok
• Snow ends by late morning
• The jackpot is southern New England as seen by the purple. 
• In the wake of this, I am tracking a potential major system for Tuesday. 
• More details in my video below

Here is my map for tonight into tomorrow AM (mainly grassy surfaces):

The video below briefly discusses this along with my thoughts on the main storm I have been focusing on for next week. Enjoy!
