Good morning everybody, we’ve got fairly pedestrian weather coming up over the next 5 days or so before we turn the firehose on for Christmas Eve as a powerful trough and storm pass just west of us, putting us on the warm side of the storm, and producing a siphon of heavy rainfall and wind right up the eastern seaboard and into New England – Hooray!!! #NOT
Backing up, for today we start off VERY cold with temps in the single digits below and above zero for the most part.
Some breaks of sunshine should lead to increasing clouds, with highs in the upper 20s to low 30s with a light wind. Lows tonight will be in the upper teens.
For Sunday, expect a cloudy day and some afternoon scattered snow or rain showers during the afternoon and evening as a weak system moves through the flow. Highs will be in the mid 30s, and some coatings are possible, especially in the high terrain of northwest MA and SVT. Lows will be in the mid 20s as the system exits east.
Monday through Wednesday looks fairly benign, with partly sunny skies Monday and a few snow showers possible overnight, with a mostly cloudy day on Tuesday. High pressure presses in and through the region to our southeast Wednesday with more sunshine.
Highs will be in the mid to upper 30s through the period, with lows in the 20s.
By Thursday, with our high east of us, and a strong low pressure system rounding the bend of a highly-amplified trough pressing into the Great Lakes and Ohio Valley, we will get into a southerly flow ahead of a sharp cold front.
This will direct strong southerly flow into our region, producing heavy rainfall up and down the eastern seaboard for Christmas Eve day.
It will quite mild on Thursday as a result with highs in the mid 40s to low 50s with showers arriving sometime before sunset, I believe, though timing may change.
If this all plays out the way it looks, heavy rainfall will sweep the region on Christmas Eve, and with warmer temps at the surface, we could see strong damaging wind gusts in the evening, which would be very 2020, and sub-optimal, to use a hyphenated euphemism.
We can’t even rule out a thunderstorm at night!
Temps will hold in the 40s at night, and as the front sweeps the region, and then colder air works in from the southwest of all directions as the low wraps way tight to our northwest, and temps will drop on Christmas Day with the potential for some upslope or lake effect snow showers, especially in the Berkshires and hills.
Colder conditions follow for the weekend. Have a great day, and stay tuned for updates on our potentially dynamic holiday rainstorm.
