DAYS 1-5 (FEBRUARY 15-19)
Low pressure will pass well south of New England tonight. Its cloud shield will filter / dim the sun as today goes on followed by the reverse process on Monday as the low pressure area heads out to sea. There will be a trough between that offshore system and another disturbance well to its northwest. Some light snow will be generated by this boundary to the west of our region but is likely to dry up in battle with dry air before ever reaching the WHW forecast area other than maybe a few stray snowflakes into CT overnight. The aforementioned disturbance in the northern jet stream will pass through our region, parent low pressure passing to our north, Monday night and Tuesday morning with perhaps a few light snow showers. We start to see the results of a shift in the weather pattern when we get to the middle of this coming week. High pressure will be building from central to eastern Canada with plenty of cold air up there, while mild Pacific air still occupies a lot of the central and eastern US. The boundary between these will establish itself somewhere in the Northeast starting Wednesday and a wave of low pressure will be coming along it, bringing clouds back into our region during Wednesday, including the chance of some precipitation later Wednesday to early Thursday, based on current expecting timing. Precipitation type will be determined by the timing / atmospheric profile, but rain/mix/snow are all on the table as possible. However, I do think this system will be on the wane, in terms of ability to produce precipitation, as it moves eastward, so at this point I’m not expecting a significant event, and we should see some drying on Thursday behind it. With the boundary so close by, the temperature forecast those days is a little tricky, so keep in mind that the numbers that I put up in that detailed forecast that follows can change a little more than is typical as I update this forecast over the next few days…
TODAY: Sunny start, then increasing clouds. Highs 31-38. Wind N up to 10 MPH.
TONIGHT: Cloudy. An overnight snow flurry possible eastern CT. Lows 21-28. Wind variable up to 10 MPH.
MONDAY: Cloudy start, then increasing sun. Highs 32-39. Wind variable up to 10 MPH.
MONDAY NIGHT: Mostly cloudy. A snow shower possible. Lows 20-27. Wind SW 5-15 MPH.
TUESDAY: Mostly cloudy with a snow shower possible early, then partly to mostly sunny. Highs 33-40. Wind W 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 13-20. Wind variable under 10 MPH.
WEDNESDAY: Clouding over. Rain/mix/snow possible afternoon. Highs 35-42. Wind N up to 10 MPH.
WEDNESDAY NIGHT: Cloudy. Mix/snow probable evening, diminishing chances overnight. Lows 28-35. Wind N to NE up to 10 MPH.
THURSDAY: Clouds break for sun at times. Highs 35-42. Wind variable up to 10 MPH.
DAYS 6-10 (FEBRUARY 20-24)
Watching for another unsettled weather threat with boundary nearby early in the period, then some snow showers mid period with upper low passing by, followed by fair and somewhat colder weather late period.
DAYS 11-15 (FEBRUARY 25 – MARCH 1)
Pattern trends a little colder and potentially stormier during the final days of February to the start of March with Canadian cold becoming more dominant but boundary region still nearby to the south.
