A relatively weak disturbance is crossing the area today bringing light amounts of snow. There is a chance that rain mixes in along the immediate coast and through Cape Ann. Snowfall accumulations will only be a coating inside of Route 128/95, which will probably be washed away where the mix to rain occurs, with upwards of an inch west of the Route 128/95 belt. A couple spots well inland could see near 2 inches but that should be the exception rather than the rule with this particular event. Some roads through the interior could become snow covered and slippery for a time.
The onset of precipitation was mid to late this morning in the local area. Precipitation should be done by this evening as this is a quick moving system. Actually, once the low gets out over the Gulf of Maine it will undergo some intensification and portions of eastern and northern Maine could see several inches of snow through the overnight.
Back home, drier air follows tonight and we can look forward to some moderating temperatures as we get into the beginning of the weekend. Although Friday will bring us a fair amount of sunshine there will be gusty breezes of up to 25 mph making it feel chillier than the actual temperatures, which are expected to be in the 30s.
We will be on the northern edge of a ridge of high pressure, centered over the Southeastern States by Friday. A southwest flow will develop by Saturday bringing milder temperatures. Many of us break 40 degrees during the afternoon.
A storm will be pulling out of the Gulf of Mexico Saturday night, crossing the Southeast early Sunday and then moving rapidly up the East Coast during the day. It is expected to move close to Nantucket Island Sunday night and then into the Maritimes Monday. The latest computer runs have pulled the track of the system a bit closer to the mainland, which means a better chance of precipitation locally. Rain could set in late Sunday, possibly mixing with snow at night, or changing over to all snow through the interior before ending. This storm bears watching and much more will be written about it over the next couple of days.
