Area Forecast Discussion National Weather Service Boston/Norton MA 702 PM EST Fri Jan 22 2021

SYNOPSIS. A few scattered snow showers across the interior late this afternoon before a strong cold front pushes through southern New England tonight. This will lead to 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 /UNTIL 6 AM SATURDAY MORNING/.

7 PM Update .

Radar reflectivity shows light returns sliding southwest from the Hudson Valley into Berkshire and Litchfield county. Another area of light reflectivity is moving from southern NH into northeast MA and skirting the Outer Cape. A look at the ASOS across our CWA shows no weather being observed at the surface. Dew point depressions of 10 to 15 degrees are indicative of the low- level dry air that any falling precip has to overcome in order to reach the ground. Hi-res guidance has generally trended less bullish with the coverage of scattered snow showers. Nonetheless, hit-or-miss snow showers could still occur just about anywhere areawide through this evening. Drying out with gusty NW winds behind the cold front passage. Otherwise, forecast remains largely on track.

PREVIOUS DISCUSSION .

**Scattered, brief heavy snow showers or snow squalls possible north and west of I-95 late-afternoon into early evening**

Latest Hi-Res guidance from the HRRR/RAP models have been slightly less bullish on the coverage of scattered snow showers across the interior this evening. However, there still appears to be enough forcing/moisture available to see some snow showers late this afternoon/early evening. As the cold front pushes these snow showers out of the region we'll see a gradual increase in winds out of the northwest by tomorrow afternoon.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/. Strong cold front exits the region overnight tonight. High pressure builds over the east coast behind the front for the weekend. This will result in clearing skies. By tomorrow afternoon, sea-level pressure gradient will tighten as the aforementioned high pressure builds over the region. This will result in gusty winds at the surface. The combination of strong wind speeds and strong CAA aloft will support much colder temperatures for the weekend. Afternoon highs tomorrow expected to top out below freezing across all of southern New England. We're also looking at the potential for sub- zero wind chill temperatures by Sunday morning. Wind gusts will peak Sunday morning with max wind gusts approaching wind advisory criteria over the outer-Cape. No headlines for now as max wind gusts top out around 39 knots over Ptown only.

LONG TERM /SUNDAY 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. Don't 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 /00Z SATURDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels.

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

00z TAF Update:

Tonight through Saturday: High confidence.

Mainly VFR, except for isolated MVFR during periods of snow showers. A cold front moving through this evening is expected to produce scattered snow showers but most locations should remain dry. VCSH for BOS through 02z and winds turning from W to NW across all terminals by 06z and becoming gusty up to 25 kt after 12z Saturday.

KBOS TAF . High confidence in TAF. Low VFR through 02z with VCSH. Winds turning NW with clearing after 06z.

KBDL TAF . High confidence in TAF.

Outlook /Sunday through Wednesday/ .

Saturday: VFR. Windy with gusts up to 30 kt.

Saturday Night: VFR. Strong winds with areas of gusts up to 40 kt.

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

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. A cold front will move across the waters this this evening. Gusty west to northwest winds develop behind this cold front tonight into Saturday. Small Craft Advisories in effect through tomorrow afternoon and will be followed by a Gale Warning as wind gusts are expected to exceed 34 knots over the coastal water. Gale warning is currently valid through Sunday evening. The air will be cold enough where there is a concern for freezing spray across most of the coastal waters late tonight into Saturday. Rough seas generally across the southern coastal waters today, but will develop farther north late tonight into tomorrow.

Outlook /Sunday through Wednesday/ .

Saturday: Strong winds with gusts up to 35 kt. Areas of rough seas. Freezing spray.

Saturday Night: Moderate risk for gale force winds with gusts up to 40 kt. Rough seas up to 11 ft. Freezing spray.

Sunday: Strong winds with gusts up to 40 kt. Rough seas up to 11 ft. Freezing spray.

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.
