DAYS 1-5 (NOVEMBER 8-12)
If you step outside this morning (or were out there overnight), you’ve been shocked by a drastic change in the feel of the air, as yesterday’s relatively high humidity and mildness has been replaced by a sharp shot of Canadian chill and very dry air, along with a gusty breeze that isn’t ready to ease up. This is the theme of our day, with little help from a low angle sun mixed with passing stratocumulus / cumulus clouds. Low temperatures this morning range from the middle 30s to lower 40s, and while the air temperature does rise into the middle to upper 40s during the day today, a continued gusty breeze will often make it feel as if it is under 40. This takes place as we get air coming in between Canadian Maritime low pressure and a high pressure area moving from the Great Lakes through Ontario and Quebec. Tonight, the wind will slacken as a narrow extension of that high pressure noses across New England, but a quick-moving west-to-east zonal flow pattern in place brings the next low pressure system our way quickly, and we’ll see the clouds fanning in from it tonight, thickening up from late evening through overnight as a push of warm air aloft moves rapidly east. This will result in a band of precipitation, some of it of the frozen variety, especially from the I-90 region northward, with mostly rain to the south. But this burst will be brief and have little impact on the WHW region. During that day Thursday as the system struggles to remain intact, we’ll see a surface frontal boundary across far southern areas and a weak wave of low pressure trying to form on it. With the exception of the South Coast which may be milder for a few hours, expect a cool, raw, cloudy November day with spotty light rain/drizzle of little consequence, eventually ending. Dry air works back in from the west Thursday evening through Friday, although the upper level remains of what was once a more organized low will rotate through the region Friday with lots of clouds. I cannot rule out a sprinkle of rain or a few pellets of ice or graupel from some of these clouds, but Friday will be largely a dry day. High pressure, still centered to our west and northwest, will provide a dry but chilly mid November weekend for us, which includes Veterans Day Saturday. Morning temperatures will be rising from the upper 30s into the lower 40s and afternoon temperatures will peak in the 40s for any parades and outdoor ceremonies scheduled that day, including a moderately gusty breeze making it feel a little colder than it is.
TODAY: Sun and passing clouds. Highs 45-52. Wind NW 5-15 MPH, gusts 20-25 MPH.
TONIGHT: Clouding over. Rain arriving west to east by dawn, may start mixed with sleet and/or snow especially interior higher elevation locations. Lows 34-41. Wind N up to 10 MPH.
THURSDAY: Mostly cloudy. Rain chance highest early southern NH and eastern MA, then spotty very light rain / drizzle possible thereafter. Highs 44-51, mildest South Coast where some locations may max out a bit warmer. Wind NE-E up to 10 MPH except may turn S or SW for a time South Coast.
THURSDAY NIGHT: Partly cloudy. Lows 28-35. Wind N up to 10 MPH.
FRIDAY: Mostly cloudy. A spot shower of rain / sleet / graupel possible. Highs 45-52. Wind N up to 10 MPH.
FRIDAY NIGHT: Clearing. Lows 25-32. Wind NW 5-15 MPH.
SATURDAY: Mostly sunny. Highs 45-52. Wind NW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 25-32. Wind NW up to 10 MPH.
SUNDAY: Mostly sunny. Highs 45-52. Wind NW 5-15 MPH.
DAYS 6-10 (NOVEMBER 13-17)
High pressure is expected to provide dry weather and keep additional unsettled weather to the south of our region from the early to middle portion of next week with a gradual temperature moderation occurring. High pressure shifts eastward after that with milder air but also an increased chance to see clouds and possible wet weather by late week.
DAYS 11-15 (NOVEMBER 18-22)
A west to east flow dominates with one or two frontal systems bringing unsettled weather chances, but no prolonged or big storms indicated. Temperatures near to above normal.
