Top Snowfall Amounts Hit Two Feet in the Merrimack Valley
Pleasant Saturday, Chance of Snow Sunday

A Shot of Wet Snow and Rain Crosses New England Friday

LKN_FRONTS_BOSDMA (16) LKN_FRONTS_BOSDMA (16)Another morning of snow started Thursday for Eastern and Central Massachusetts as the last of the upper level atmospheric energy that drove the early week Northeast winter storm drifts overhead, on a slow departure to our east.  Drier air breaking out sunshine in New England Thursday morning and afternoon will be battled by lingering moisture for variable new, building clouds.  After a clear night of falling temperatures Thursday night, a quick-moving disturbance arriving Friday will have the stage set to begin as a shot of wet snow anywhere near and north of the Massachusetts Turnpike in a brief round somewhere near the 5 to 9 AM timeframe, west to east, respectively.  This first round of snow showers drops a coating of morning snow for many – mixed with raindrops in far Southern New England – will represent an arriving shot of milder air that will bump temperatures into the 40s in Southern New England by afternoon so steadiest precipitation will fall as mostly rain in Central and Southern New England, though snow will continue falling in Northern New England with one to three inches of accumulation expected, with locally higher amounts in the higher terrain.  Clearing Friday night makes way for a fair and relatively pleasant Saturday regionwide with some appreciable melting as temperatures near 40 degrees.  With the jet stream winds aloft – the fast river of air that steers storm systems and separates northern cool air from southern milder air – flowing near to New England this weekend into early next week, our First Alert Team will have a few disturbances to watch carefully.  After Friday’s quick-moving storm system, another storm is set to develop relatively nearby on Sunday – the merger of northern energy and cold air with southern moisture.  At this point, it appears that powerful merger happens just a bit east of New England, meaning snow showers Sunday afternoon and evening are more likely than a snowstorm, but with energetic players on the map we’ll continue keeping a close eye.  After another one day break Monday, a new set of energetic disturbances passes close on Tuesday…with the exact storm track dependent on the timing of the arrival of a shot of hearty cold from Canada.  Because storms tend to develop on or near the battlezone between cold and warm, the speed of next week’s cold will be key on paving the way for Tuesday’s storm: if the cold push is on the slower side, New England is dealt accumulating snow and perhaps a rain/snow line Tuesday, while if the cold push is faster, the storm is nudged southeast of New England.  For now, our exclusive First Alert 10-day forecast maintains a chance of snow and rain Tuesday, with the more meaningful cold air arriving immediately thereafter for the middle and end of next week.  We’ll certainly keep you posted on-air and online.
