DAYS 1-5 (MARCH 11-15)<\/p>\n\n\n\n
A weekend split, though the unsettled day, today, is not all that bad. Low pressure made a run at the region, getting its clouds in and areas of snow and rain, but mainly on the lighter side, with some minor accumulation of snow mainly in the higher terrain well to the west and southwest of Boston. This area of precipitation will dry up as low pressure is deflected southeastward, eventually to become a potent storm over the water south and southeast of New England. While this process takes place, an increasing onshore wind will bring some rain and snow showers in from the ocean during the day and into this evening which can result in brief minor accumulation of snow (where they occur as snow). Exit this system tonight and enter an area of high pressure for a nice Sunday, but this interlude of nice weather will be rather short-lived too. Attention is on the evolution and development \/ movement of a significant storm system slated to impact our region later Monday to Wednesday. I’m not going to go into significant detail on today’s blog post about this storm. I will expand upon it significantly on tomorrow’s, however. For now, I’ll summarize my thoughts on the event this way. It’s going to be the most potent storm we directly deal with that will produce significant snow for at least part of the region this winter season (yes, it’s still winter, not spring). Low track (both surface and upper level) very important as always, but extremely so in determining precipitation profile. A slight but model-wide shift southeastward has taken place with global guidance overnight and the most recent runs (before the writing of this blog) show a solid process of dynamic cooling, ending up making more of the region see snow than rain. (Again, a guidance comment, not my actual locked-in final forecast just yet.) I bring this up because this is a process I’ve already mentioned would be a part of this storm, regardless of its track. Areas that see significant snow don’t have to be sitting in a cold airmass beforehand. Storms manufacture cold and bring it down from directly overhead in the right set-up, and this will be the right set-up for that. Snow load and wind issues will exist – details TBD. Resultant power outages will be a significant threat. Coastal issues will be limited due to astronomical low tides, fortunately, but with a potent low center likely to be passing just south and east of our region, the threat of high tide splash-over and flooding will still exist. Looking at a Monday night start time for initial precipitation favoring rain east, snow west, into Tuesday when sometime during that day, depending on the low’s track, we see the cooling take place and a rain\/snow line head eastward, maybe irregularly depending on the rate of cooling via precipitation intensity (example, it could start snowing in Boston before some of its nearby western suburbs). The storm center may do a cyclonic loop \/ stall briefly, so the impacts likely linger into a portion of Wednesday as well. More refined detail and timing on these things with tomorrow’s post…<\/p>\n\n\n\n
TODAY: Mostly cloudy. Areas of mainly light rain\/snow favoring south central through southeastern MA, eastern CT, and RI during the morning. Scattered rain and snow showers favoring NH Seacoast and eastern MA this afternoon. Very minor and temporary snow accumulations possible in some areas. Generally steady temperatures 35-42. Wind NE-N 5-15 MPH, higher gusts, especially coastal areas.<\/p>\n\n\n\n

DAYS 6-10 (MARCH 16-20)<\/p>\n\n\n\n
Quiet start and end to this period. Mid period unsettled weather potential. Temperatures variable, averaging near normal. Vernal Equinox – March 20.<\/p>\n\n\n\n
DAYS 11-15 (MARCH 21-25)<\/p>\n\n\n\n
Early days of spring look active with the good shot at a couple low pressure systems impacting the region with rain\/mix\/snow potentials and temperatures back to below normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
