DAYS 1-5 (JANUARY 5-9)
We continue to watch a blocking pattern establish itself with visible evidence in low pressure temporarily stuck off our eastern coastline, which will continue to through cloudiness and occasional rain & snow showers back into the region, especially eastern areas, through early Wednesday, before it heads out and high pressure takes its place later in the week with seasonably chilly, dry weather. The next storm system will very likely head out to sea south of New England, with our area only seeing some high cloudiness from it later Friday into Saturday. This is due to the block’s positioning and strength and the resulting storm track being forced well to the south. This particular block is also keeping the cold air on the “other side” of the pole, with parts of Asia & Europe much colder while North America is not so cold.
TODAY: Mostly cloudy. Rain/snow showers favoring NH Seacoast, eastern MA, and possibly RI. Highs 32-39. Wind N 5-15 MPH interior except 15-25 MPH eastern coastal areas.
TONIGHT: Mostly cloudy. A few snow showers lingering in eastern areas. Lows 25-32. Wind N 5-15 MPH.
WEDNESDAY: Mostly cloudy early morning with a lingering snow shower possible in eastern areas, then partly sunny. Highs 35-42. Wind N-NW 5-15 MPH.
WEDNESDAY NIGHT: Clearing. Lows 22-29. Wind NW 5-15 MPH.
THURSDAY: Sunny. Highs 33-40. Wind variable 5-15 MPH.
THURSDAY NIGHT: Clear. Lows 18-25. Wind variable up to 10 MPH.
FRIDAY: Mostly sunny but some increasing high clouds later in the day. Highs 36-43. Wind variable up to 10 MPH.
FRIDAY NIGHT: High overcast. Lows 20-27. Wind variable up to 10 MPH.
SATURDAY: Filtered sun with high clouds to start, then brighter sunshine. Highs 37-44. Wind variable to N 5-15 MPH.
DAYS 6-10 (JANUARY 10-14)
The blocking pattern will remain in place. The next storm threat is in the January 12-13 window and this one may get a little closer to the region than the one before it, so we’ll have to keep a close eye on it. Temperatures not too far from normal.
DAYS 11-15 (JANUARY 15-19)
With low to moderate confidence I look for a weak system to pass through with minor precipitation about January 15 and a break-down of the large scale blocking pattern, which for our area probably means dry, colder weather overall. Have to watch for any disturbances from the west that medium range guidance is not picking up on solidly this far in advance.
