DAYS 1-5 (NOVEMBER 15-19)
A frosty morning greeted early-risers today, not that we haven’t seen frost already in much of the area this autumn, but areas that had not seen it previously have now, and many areas that had not seen a hard freeze previously also now have, with only a few urban and immediate coastal exceptions left. Those areas will get there too before too long in this newly emerged weather pattern, which features below normal temperatures for a while – a well-forecast pattern by medium range guidance I might add. Today, we start bright, but end cloudy as high pressure over us now loosens its grip and gives way to approaching low pressure from the southwest. This low center will give us an unsettled Wednesday with precipitation arriving from southwest to northeast in the late evening hours as rain South Coast, snow in many areas near and north of I-90, and a mix area between. The quicker it comes in, the longer it can snow where that takes place. This may make some areas a little slick for the early part of Wednesday’s commute, but a quick transition to rain will be underway already. Equally if not more hazardous across the region will be wet leaves in areas they cover roads and walkways, as well as some possible flooding around clogged catch basins. Keep all of these potential hazards in mind if needing to travel early Wednesday. Later in the day the rainfall will taper off and clearing will commence but not until after dark. Thursday through Saturday will feature mainly dry, chilly weather with a northwesterly air flow. Upper level low pressure having to cross the region on Thursday, however, will bring with it a chance of a few passing light rain and snow showers (snow showers most likely interior hills).
TODAY: Sunny start / mostly cloudy finish. Highs 43-50. Wind N-NE up to 10 MPH.
TONIGHT: Cloudy. Precipitation arriving overnight as snow/sleet southern NH and northeastern through central MA with up to around 1 inch of snow/sleet in highest elevations southwestern NH / north central MA with rain South Coast and some mix between but no accumulation of snow beyond a brief coating on cold surfaces, then all areas rain by about dawn. Lows 32-39. Wind NE up to 10 MPH.
WEDNESDAY: Cloudy with periods of rain, ending in the afternoon. Areas of fog. Highs 41-48. Wind NE 5-15 MPH inland and 15-25 MPH coast, higher gusts especially Cape Cod and Islands shifting to NW during the afternoon.
WEDNESDAY NIGHT: Partly cloudy. Lows 34-41. Wind NW 10-20 MPH, a few higher gusts.
THURSDAY: Sun/cloud mix. A passing rain or snow shower possible – snow showers most likely interior locations / higher elevations. Highs 40-47. Wind NW 10-20 MPH, higher gusts.
THURSDAY NIGHT: Partly cloudy. Lows 25-32. Wind NW 5-15 MPH.
FRIDAY: Partly cloudy. Highs 38-45. Wind NW 5-15 MPH.

SATURDAY: Mostly sunny. Highs 38-45. Wind NW 5-15 MPH.
DAYS 6-10 (NOVEMBER 20-24)
Dry weather and below normal temperatures to finish off the weekend into early next week, then moderating temperatures and mainly dry into midweek. May have a low pressure or frontal system approaching by Thanksgiving (Nov 24) but that’s day 10 and really too soon for any detail.
DAYS 11-15 (NOVEMBER 25-29)
Unsettled weather potential to start the period, and again very late in the period, otherwise mainly dry with temperatures near to below normal.
