Synopsis
Mainly dry, blustery and much colder today, although a few Blustery weather and below normal temperatures continue through the rest of the week into Saturday with nothing more than a few brief passing rain/snow showers. A frontal system may bring mostly rain next Sunday with drier conditions Monday.

Near Term - Through Tonight
Key Messages:

* Gusty winds continue into the evening before winding down after midnight

* Chilly with sub-freezing lows and wind chills in the 20s.

Gusty winds from this afternoon persist through about midnight before an upper-level trough axis and associated low-level jet shifts east this evening and overnight. Until then, gusty westerly winds from 25-35 mph will be possible, with gusts up to 45 mph possible over Nantucket where a Wind Advisory remains in effect.

Roughly after midnight, a mid-level ridge building over The Northeast will allow the pressure gradient to relax and westerly winds to diminish. While the stronger 20-30 mph gusts will come to an end, westerly winds will still be steady around 10 mph. Thus, with mechanical mixing and continued mid-level cloud cover, we're not anticipating any significant radiational cooling tonight. Nonetheless, the air mass still remains cooler than normal and we can expect low temps near or below freezing for most of southern New England. Steady winds will have the "feels like" temperatures in the 20s for most of the region as well.

Short Term - Wednesday Through Wednesday Night
Key Messages

* A few rain/snow showers early followed by a slight uptick in temperatures

* Quiet weather tomorrow night with lows once again in the 30s

Weak short-wave energy may trigger a few rain showers over the south coast, Cape, and Islands early tomorrow morning. Also can't rule out a few snow showers over The Berkshires and Worcester Hills, but most locations will remain dry. Southwest flow develops allowing modest low-level WAA (Warm Air Advection - the movement of warm air) tomorrow afternoon which will support 925 hPa temps rising a few degrees from Tuesday. This will result in high temperatures about 5 or 6 degrees higher than Tuesday. Cloudy skies early will give way to partial sunshine in the afternoon with steady west winds. Skies then scatter out tomorrow night as west/northwest flow ushers in a drier air mass. Low temps once again in the low to mid 30s.

Long Term - Thursday Through Monday
Key Messages

* Chilly temperatures continue through the weekend

* A low pressure system will bring rain and possibly frozen precipitation to southern New England Saturday night through Sunday

Thursday through Saturday

Deep northwest flow will support persistent Cold Air Advection over The Northeast Thursday through Saturday morning. This will continue to support below normal temperatures with daily highs/lows in the mid 40s/ upper 20s-low 30s respectively. A dry column and surface high pressure should support more sun than clouds during this time frame.

Saturday night through early next week

By Saturday night, model guidance is revolving a robust pulse of short-wave energy digging southeast over The Great Lakes and across The Northeast. This is expected to bring substantial precipitation to southern New England with 24 hour ensemble mean precipitation forecast coming in around a half inch. Additionally, many solutions support a setup that would involve warm air aloft overrunning shallow sub-freezing air at the surface. This may introduce some precipitation type issues to the forecast where we some locations may be dealing with a wintry mix. Details are vague at this time range, but this will be something to watch closely as we approach the weekend. Strong cold air advection behind this system will continue to support below-normal temperatures as we head into early next week. Stay tuned for further details... Marine
Forecaster Confidence Levels... Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent.

Key Messages:

* Gale force winds continue overnight before diminishing tomorrow morning

Gusty gale force westerly winds continue this afternoon and evening over the coastal waters. Winds weaken below Gale Force tomorrow morning, but SCY criteria persists through tomorrow afternoon for most of the marine zones. Expect faster improvement over the eastern waters where SCY conditions diminish by early-mid afternoon. Seas over outer southern marine zones remain elevated through tomorrow night with significant wave heigheights between 6 and 8 feet.

Outlook /Thursday through Saturday/... Wednesday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Slight chance of rain.

Thursday: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Local rough seas. Chance of rain.

Thursday Night: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of rough seas. Chance of rain.

Friday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Local rough seas. Slight chance of rain.

Friday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of seas approaching 5 ft. Slight chance of rain.

Saturday: Winds less than 25 kt. Seas locally approaching 5 ft.
