Area Forecast Discussion National Weather Service Boston/Norton MA 221 AM EST Sat Jan 23 2021

SYNOPSIS. A cold and blustery weekend with possible sub-zero wind chills by Sunday morning. Looking ahead to next week is a complicated forecast for Tuesday. Models remain in disagreement about a coastal low and the coverage of any snowfall. Then, drier and cooler weather Wednesday through the end of next week.

NEAR TERM /THROUGH TODAY/. The core of a high pressure remains to our west today. While this high should be close enough to keep our weather mainly dry, it will not be quite close enough to force winds to diminish. In fact, expecting the opposite effect where the modest cold air advection will increase the gradient wind across southern New England, especially this afternoon.

Temperatures will be below normal today, with most areas not getting out of the 20s.

Cannot rule out a few snow showers or flurries this morning, especially towards the east coast.

SHORT TERM /TONIGHT THROUGH 6 PM SUNDAY/. Not much change in conditions tonight into Sunday. Still gusty winds and turning sharply colder compared to what we have been most of this month. Minimum wind chill temperatures tonight below zero across most of southern New England. Not low enough where am thinking we would need a Wind Chill Advisory. Thinking we could see some isolated gusts up to Wind Advisory strength across the outer Cape tonight. Will let the next shift reevaluate.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. Highlights .

* Dry, breezy, and chilly weekend ahead - wind chill values in the single digits and teens Saturday afternoon.

* Potential coastal low could bring snow to southern New England Tuesday.

* Dry and cool stretch of weather for remainder of next week.

Sunday through Monday Night:

Dry, cold, and breezy describe how southern New England will wrap-up this coming weekend. While we aren't anticipating much "weather" this weekend - many are likely to strike up a conversation about the chilly conditions.

The weather this weekend is dominated by an area of high pressure - leading to mainly clear skies early Sunday and through Monday afternoon. Our location on the eastern side of the high will allow for a northerly wind. Plus there will be a sharp pressure gradient over southern New England - enhancing wind gust and wind chill value. Aloft, temperatures at 925mb are between -10C and -15C during the afternoon hours. That will yield afternoon temperatures in the 20s inland and near freezing at the coast. These temperatures aren't abnormally cold, as the average high this time of year are between the low and mid 30s. But, when factoring in a north wind, it will feel as if the temperatures were in the low single digits inland and the mid- teens at the coast. Gusts are generally 15 to 25 miles per hour away from the coast with the the strongest gusts of 25 to 35 miles per hour at the Cape and Islands.

As the high shifts east Sunday night into Monday we lose the tight pressure gradient and winds will diminish. After a cooler start in the low teens across the interior and the teens to low 20s for the coastal plain the afternoon temperatures will rebound to the low and mid 30s. With light wind there will be no wind chill as highs reach the low and mid 30s. Clouds will filter back in the second half of Monday afternoon as a coastal storm approaches from the south.

Tuesday into Tuesday Night:

Models are in good agreement a low will develop across the Ohio Valley Monday afternoon/evening before moving to the east northeast. The biggest question remains how far north will the system track. Models show a secondary low will develop off the coast of the Mid Atlantic, but with a 1040 high over eastern Canada, it becomes difficult for low to to make a north run.

As of the 12z guidance the Canadian is "your friend" that is, if you are a snow lover! The model shows a widespread light snowfall event across off of Massachusetts, Connecticut, and Rhode Island. Do not get your hopes too high as the GFS/ECMWF are keeping the bulk to the south, but the precipitation shield does extend into southern areas of Connecticut and Rhode Island. The models are in some agreement in terms of the timing Tuesday morning through Tuesday evening - a fairly progressive system.

Wednesday through Friday:

To wrap up the long term fairly quiet weather returns as high pressure returns to southern New England - starting Tuesday night through Friday. The only outlier happens to be the Canadian which shows an additional coastal low pressure system with wintry weather for Thursday afternoon and night. Otherwise, temperatures for the rest of the week remains near or slightly below average for late January.

AVIATION /07Z SATURDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels.

Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.

Today through Sunday: High confidence.

Mainly VFR, except for isolated MVFR during periods of snow this morning. Strong gusty NW winds developing today, and lingering through Sunday.

KBOS TAF . High confidence in TAF.

KBDL TAF . High confidence in TAF.

Outlook /Sunday Night through Wednesday/ .

Sunday Night: VFR. Strong winds with local gusts up to 40 kt.

Monday: VFR. Breezy.

Monday Night: Mainly VFR, with local IFR possible. Chance SN.

Tuesday: MVFR/IFR conditions possible. Breezy. Chance SN.

MARINE. Gusty west to northwest winds develop across the waters and linger through Sunday. Gale Warnings remain in effect through Sunday evening. The air will be cold enough where there is a concern for freezing spray across most of the coastal waters into Sunday. Still thinking about the need for Freezing Spray Advisories for the eastern coastal waters tonight due to the possibility of moderate freezing spray. Threat of freezing spray diminishes some during the day Sunday.

Outlook /Sunday Night through Wednesday/ .

Sunday Night: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of rough seas. Freezing spray.

Monday: Winds less than 25 kt. Areas of seas approaching 5 ft.

Monday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of snow. Areas of visibility 1 to 3 nm.

Tuesday: Winds less than 25 kt. Seas up to 5 ft. Chance of snow. Visibility 1 to 3 nm.
