SYNOPSIS
An arctic front moves through overnight into Monday morning with a low chance for brief scattered snow showers, primarily for northern MA. Well below normal temperatures Monday with an arctic airmass overhead. More unsettled overall next week with a few systems moving through the region. This will bring periodic chances for rain/snow showers starting Tuesday night, continuing into Saturday. Very gradual warming trend into Tuesday with highs around normal Wednesday/Thursday.
NEAR TERM /THROUGH MONDAY/
Key Messages...
* A mostly dry arctic front drops through overnight bringing in a period of below normal temperatures.
Quiet end to the weekend in progress; main changes this afternoon are in influx of mid/high clouds ahead of a weak mid level shortwave that crosses northern New England overnight. At the surface a moisture starved arctic front drops through between 8pm and 3am.
Again, moisture is so limited that it will more than likely be a dry frontal passage; worst case is some light snow showers in northern MA amounting to a coating of snow. A much colder airmass moves overhead with 850 mb temps dropping from -7C Sunday to -17C Monday.
As the surface low deepens over the Gulf of Maine Monday the pressure gradient increases so breezy winds will make highs in the 20s feel like the teens.
SHORT TERM /MONDAY NIGHT/
Key Messages...
* Well below normal temperatures.
High pressure builds overhead Monday night and the boundary layer decouples; this allows the already cold airmass to cool even more.
Expect lows in the single digits (inland) and low/mid teens (along the coast).
LONG TERM /TUESDAY THROUGH SATURDAY/
Key Messages:
* Periodic chances for precipitation next week starting Tuesday night, continuing through Saturday.
* Uncertainty in pattern details (timing, amounts, precip type), especially Wednesday onward.
Rather good overall agreement with the synoptic pattern through Tuesday. After then, the timing and amplitude differences continue to grow into next weekend. The overall pattern suggests a deepening mid level trough over the eastern USA for the second half of this upcoming week. The largest detail differences involve the evolution of a mid level cutoff somewhere between Hudson Bay and Quebec. Our proximity to this particular feature will play a role in how much lift can be used to generate cold advection showers across our region.
Surface high pressure should move offshore Tuesday, permitting a low pressure moving into the Great Lakes to push its associated fronts across southern New England Tuesday night into Wednesday. Not expecting a lot of precipitation during this time, but some light snow will be possible at night, and especially across the higher terrain. Anticipating more rain than snow Wednesday as temperatures rise to near normal levels.
Late next week could feature some cold advection showers, but there are no strong lifting mechanisms anticipated at this time. There are also questions about the amount of moisture which could be available. While there is a prolonged period where these showers are possible, there should be many dry hours late next week. There is higher confidence in the arrival of colder air by the end of next weekend with below normal temperatures returning to our region.
