DAYS 1-5 (NOVEMBER 9-13)
A seasonably cool northwesterly air flow dominates our weather early this week. A trough moving through today and a cold front moving through tomorrow will both be moisture-starved with only a slight chance of quick-passing light rain showers, otherwise expect dry, breezy, variably cloudy conditions. Wednesday, Veterans Day, will feature more sunshine and a westerly breeze with high pressure to our south. Then we turn our attention to developing / evolving low pressure coming out of the Ohio Valley. My expectation is that an initial low pressure area will move from the Ohio Valley toward the Mid Atlantic Coast where it will redevelop. The new low and the old low will do a partial “dumbbell pivot” where the newer low starts to track northeast and elongating upper low pressure starts to pull the older low a little more to the south. The pair of lows are likely to pass south of New England Friday and Friday night. Results: Cloudiness increases Thursday, and a rain chance begins Thursday night and lasts through Friday, with highest probability for steadiest rain would be in the southeastern half of the WHW forecast area (eastern CT, and RI up to Boston MA area eastward), with the chance lowering the further northwest you go. Of course this would shift if the storm track shifts, and that is something to monitor as we get closer. You may have head a lot of talk about snow regarding this storm threat, but the only way snow gets involved in the WHW forecast area would be a slightly closer track, heavier precipitation, and marginally cold enough air in the higher elevations of southwestern NH into central MA. While it’s still several days away, I am currently not leaning in that direction.
TODAY: Plenty of clouds / intervals of sun, and the chance of a quick-passing rain shower. Highs 52-59. Wind NW 10-20 MPH, higher gusts.
TONIGHT: Partly to mostly cloudy. Lows 36-43. Wind W 5-15 MPH.
TUESDAY: Mostly to partly cloudy. Slight chance of a quick-passing rain shower. Highs 52-59. Wind NW 5-15 MPH, higher gusts.
TUESDAY NIGHT: Clearing. Lows 37-44. Wind NW 5-15 MPH.
WEDNESDAY (VETERANS DAY): Mostly sunny. Highs 55-62. Wind W 5-15 MPH.
WEDNESDAY NIGHT: Clear. Lows 35-42. Wind W up to 10 MPH becoming variable.
THURSDAY: Increasing clouds. Highs 48-55. Wind variable becoming E 5-15 MPH.
THURSDAY NIGHT: Overcast. Rain likely southeast / chance of rain northwest. Lows 38-45. Wind E 5-15 MPH except 15-25 MPH South Coast.
FRIDAY: Overcast. Rain likely southeast / chance of rain northwest. Highs 45-52. Wind E to NE 10-20 MPH except 20-30 MPH South Coast especially Cape Cod, with higher gusts possible.
DAYS 6-10 (NOVEMBER 14-18)
Surface low pressure pulls away but upper level low pressure trough moves through during the November 14-15 weekend with breezy, cool conditions. May be lingering showers early weekend, otherwise generally dry weather expected. High pressure builds in with fair, initially cool then milder weather early to middle portion of next week.
DAYS 11-15 (NOVEMBER 19-23)
Milder pattern indicated. Leaning dry into mid period and unsettled weather chance later in the period, but no major storminess foreseen at this time.
