DAYS 1-5 (JANUARY 4-8)
The danger of the media speaking in absolutes will be proven, once again, today, by the lack of 60+ degree weather that many an outlet touted days in advance. While our area professional forecasters were cautious, many of the headline makers were not, so it ends up as misleading information. Now, I myself also spoke of 60 degree possibilities a few days ago for today, but with caution, as you know, with high pressure in eastern Canada being a potential thwarting influence on the big warm up. The observations at dawn today speak for themselves, showing a frontal boundary sitting right on the South Coast where temps are in the lower 50s, with the rest of the region in the upper 30s to lower 40s with either a light northerly or easterly wind. That frontal boundary may make a little bit of progress northward this morning, but any of that will be temporary, and the boundary will be shoved back to the south tonight and on through the end of the week. While this is taking place, a strung out area of low pressure will continue to provide us with a cloudy sky and occasional precipitation, which will tend more toward the freezing / frozen variety with time. The good thing is that as this happens, the quantity of precipitation will be limited, so the impacts will be lessened from that aspect of it. However, this does not change the fact that untreated surfaces will easily show the effects of the lowering temperatures as we move through Thursday and into Friday. The weekend’s outlook is improved, as it looks like most of the upper level energy I’d given as the reason for a chance of snow showers Saturday should be offshore before the day begins, thus allowing me to remove that chance from the forecast, just leaving it as a day of sun and passing clouds with a gusty breeze and seasonably chilly air. Sunday’s weather would be more tranquil as high pressure moves overhead but high clouds would already be appearing ahead of the next weather system in a Pacific jet stream pattern.
TODAY: Overcast. Areas of fog. Chance of drizzle, especially I-90 belt north. Highs 40-47 southern NH and northern MA and 48-55 elsewhere morning to midday, then cooling temperatures from north to south during the afternoon. Wind SW up to 15 MPH South Coast, N to E under 10 MPH elsewhere, becoming NE up to 10 MPH all areas from north to south by late.
TONIGHT: Overcast. Areas of fog evening. Periods of rain which may convert to freezing rain over inland areas of southern NH and northern MA overnight. Lows 31-38. Wind NE to N up to 10 MPH.
THURSDAY: Cloudy. Periods of rain except potential freezing rain early in the day interior southern NH and northern MA, may mix with snow starting north and trending south during midday and afternoon. Highs 33-40, mildest South Coast. Wind NE to N 5-15 MPH.
THURSDAY NIGHT: Cloudy. Periods of light rain, which can and likely will freeze on surfaces away from the coast, and possibly sleet. Lows 27-34. Wind N 5-15 MPH.
FRIDAY: Mostly cloudy. Chance of light snow except some mix/rain possible South Coast. Highs 34-41. Wind N to NW 5-15 MPH.
FRIDAY NIGHT: Mostly cloudy. A snow flurry possible. Lows 25-32. Wind NW 5-15 MPH.
SATURDAY: Sun and passing clouds. Highs 36-43. Wind NW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 18-25. Wind N up to 10 MPH.
SUNDAY: Sun and high clouds. Highs 35-42. Wind variable up to 10 MPH.
DAYS 6-10 (JANUARY 9-13)
This range continues to be forecast with moderate confidence as guidance remains questionable and the pattern remains fast-Pacific-flow-driven. Opportunities for unsettled weather exist January 9 and January 12-13, based on current trends and expected timing. Temperatures near to slightly above normal.
DAYS 11-15 (JANUARY 14-18)
Continued lower confidence in forecasting this far out with opportunities for storminess probably twice during these 5 days and temperatures near to slightly above normal with the same general pattern idea. Some hints in the longer range that the pattern may start to shift to a colder, drier one with a northwesterly flow, but I’m not convinced this won’t be delayed initially. Much time to figure that out.
