DAYS 1-5 (MARCH 11-15)
High pressure gives way to an approaching disturbance today, so a sunny start turns into a cloudy finish, but any precipitation with the passing disturbance tonight, although it may be in the form of mix/snow in southern NH and northern MA while falling as rain to the south, will be on the light side. Clouds will be more stubborn and will hang around a good part of Thursday in between weather systems, so we may need luck to see much sunshine (let’s hope this forecast is too pessimistic). Next low pressure system is a quick mover and I am moving up the timing from yesterday’s update, so that we should be seeing rain arrive west to east Friday morning and depart west to east by evening. With a bit of luck the wettest weather will occur between the 2 main commutes. The weekend: Canadian high pressure moves in, dry/cool/breezy Saturday, dry/less wind/colder Sunday.
TODAY: Sunny start, cloudy finish. Highs 51-58. Wind W 5-15 MPH.
TONIGHT: Cloudy. A period of light snow/mix/rain southern NH and northern MA, light rain to the south. Lows 32-39. Wind variable up to 10 MPH.
THURSDAY: Mostly cloudy. Highs 40-47. Wind variable up to 10 MPH.
THURSDAY NIGHT: Mostly cloudy. Lows 30-37. Wind variable up to 10 MPH.
FRIDAY: Cloudy through mid afternoon with a period of rain late morning to mid afternoon. Breaking clouds late day. Highs 48-55 except may briefly reach 55-62 in some southern areas. Wind SE 5-15 MPH shifting briefly to SW then W and increasing to 10-20 MPH and gusty late day. FRIDAY NIGHT: Clearing. Lows 32-39. Wind W 10-20 MPH, higher gusts.
SATURDAY: Sun and passing clouds. Highs 43-50. Wind W 10-20 MPH, higher gusts.
SATURDAY NIGHT: Clearing. Lows 28-35. Wind NW 5-15 MPH.
SUNDAY: Mostly sunny. Highs 38-45. Wind NW 5-15 MPH.
DAYS 6-10 (MARCH 16-20)
Fair and chilly under the influence of Canadian high pressure March 16. Disturbance from the west brings light precipitation at times March 17, anything from snow to sleet to rain possible, but a minor system. Fair weather returns March 18. High degree of uncertain thereafter. For now, still leaning toward mainly dry weather and a warm-up for March 19-20, but there is reliable guidance which says otherwise, but is inconsistent from previous forecasts. Will re-evaluate.
DAYS 11-15 (MARCH 21-25)
A boundary nearby continues to make for even more uncertainly in an already normally uncertain beyond-10-day forecast. We’ll have to watch for a quick turn to cold and still cannot rule out something frozen falling from the sky sometime during this period.
