DAYS 1-5 (NOVEMBER 13-17)
Most of the next 5 days will feature dry weather. The week will start chilly and end with a warming trend. A quick-moving disturbance in a northwesterly air flow will bring clouds in later today, then some rain and snow showers through the region this evening and tonight. Other than the low chance of a brief coating of snow in a few places in southern NH and central to possibly northeastern MA, this will be an inconsequential event. The disturbance exits early Tuesday but a fresh push of cold air and a northerly air flow behind the system can create a few rain showers on Outer Cape Cod while some cloud bands move from north to south near and just off the eastern coastline. High pressure builds in for fair and more tranquil weather Wednesday before it pushes offshore later Wednesday and Thursday, allowing a warm-up to begin. By Friday, with high pressure off to the east and northeast, low pressure to the south, and a trough of low pressure and frontal system approaching from the west, we’ll see increasing cloudiness. The opportunity for wet weather then increases by later on Friday, but I’m not certain just yet of the timing and the scope of any rainfall and will fine-tune that part of the forecast as we go through the next several days.
TODAY: Sun followed by clouds. Highs 41-48. Wind W up to 10 MPH.
TONIGHT: Mostly cloudy this evening with passing rain and/or snow showers. Partly cloudy overnight. Lows 28-35. Wind W 5-15 MPH shifting to NW.
TUESDAY: Sun and passing clouds – most clouds near the coast and especially Outer Cape Cod where a few rain showers are possible. Highs 42-49. Wind NW to N 10-20 MPH, higher gusts possible in eastern coastal areas.
TUESDAY NIGHT: Clear. Lows 25-32. Wind NW diminishing to under 10 MPH.
WEDNESDAY: Sunny. Highs 45-52. Wind W up to 10 MPH.
WEDNESDAY NIGHT: Clear. Lows 25-32. Wind SW up to 10 MPH.
THURSDAY: Partly cloudy. Highs 52-59. Wind SW 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Lows 35-42. Wind SW up to 10 MPH.
FRIDAY: Partly to mostly cloudy. Late-day rain showers possible. Highs 56-63. Wind S 5-15 MPH.
DAYS 6-10 (NOVEMBER 18-22)
Low pressure passes by to the southeast and another low passes by to the north with a trailing frontal boundary moving through the region at the start of the weekend on November 18. The amount and duration of rain will be determined by the interaction of these systems, but early on I lean toward the greatest chance of wet weather the first half of Saturday and favoring eastern and southern portions of the region, before it dries out later. Generally dry, chilly weather follows to end the weekend and start Thanksgiving Week, but have to watch for another low pressure system with an unsettled weather threat by the end of this period, which would be about the day before Thanksgiving, based on current medium range timing, which is not high confidence.
DAYS 11-15 (NOVEMBER 23-27)
Trend is for a mainly dry and somewhat seasonable though variable temperature regime heading from Thanksgiving through its holiday weekend time period with a westerly flow and a lack of significant moisture in the region.
