Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

SYNOPSIS. A cold and blustery weekend with possible sub-zero wind chills by Sunday morning. Winds slacken on Sunday night as high pressure builds into Southern New England through Monday night. A system passing to our south may bring a minor accumulation of snow south of the Massachusetts Turnpike on Tuesday. High pressure then becomes re-established for most of the workweek, with temperatures around seasonable levels. A coastal low near the mid-Atlantic waters on Thursday may brush our far southern areas or pass far enough south to be a miss.
NEAR TERM /UNTIL 6 PM THIS EVENING/.
1 PM update .
Arctic front continues to drop through southern New England after bringing a dusting to half inch of snow from Worcester east to the outer Cape. Showers have largely moved offshore and things should be dry the rest of the day. Winds are gusting 25 to 30 mph and will remain elevated.
Previous Discussion .
Radar showing some southeastward-moving snow showers into the Route 2 corridor and the Merrimack Valley. These will continue to pass southeast toward the North Shore/Metro Boston and offshore. As they do so however, they will briefly reduce visibility and perhaps produce a coating of new snow. Expect by mid- morning that these passing snow showers will have moved into the coastal waters.
Otherwise, considerable cloudiness and northerly winds have kept current temperatures running milder than forecast expectations. We're also still awaiting the arrival of the colder/drier air which still is back across central NY. Expect onset of cold advection around mid morning, with increasing northwest wind gusts. Didn't make any changes to temps, which appear on track.
4 AM update:
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 /6 PM THIS EVENING 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 weather prevails through Monday night under high pressure.
* Light-accumulating snow mainly across western MA, CT into southern RI Tues as system passes to our south.
* High pressure returns for mid to late week with mainly dry weather; do have to monitor coastal storminess near the mid- Atlantic region Thurs that may brush our southern areas but not a sure bet.
Details:
Sunday Night into Monday:
High pressure over the Appalachians continues to build east into our area Sunday night, and remains established across Southern New England through Mon night.
For Sunday night, we should see slackening NW wind speeds early, taking longer to occur across eastern coastal MA. Good radiational cooling seems likely, especially our interior areas where winds will ease sooner than areas further east. MOS ordinarily would do fairly well in such a pattern for temperatures, but may be too cold given its assumptions that there is a snowpack; so for lows I utilized an NBM/MOS blend to not go quite as low as MOS would reflect. Brings lows mainly into the low-mid teens, with single digits across parts of the Pioneer Valley and into the Berkshires.
High pressure continues to govern on Mon, with full sun turning filtered late in the day. By evening, most areas should trend OVC in terms of sky cover. Under modest northerly winds which should turn more NNE/NE by Mon night, showed upper 20s to upper 30s highs with lows mid teens to lower 20s.
Tuesday into Tuesday Night:
Primary low pressure at 12z Tues over IL/IN, associated with a 500 mb shortwave trough which rounds the northwest periphery of a ridge axis over the coastal southeast CONUS. Shortwave aloft more or less shears out as it nears the mid-Atlantic/lower Hudson Valley region on Tues, with secondary coastal development taking shape later Tues into Tues night.
00z guidance suite seems to be coming into better agreement on what is appearing to be a light-accumulating snow for Tues into Tues evening. Of the deterministic guidance, the GFS is the furthest north and also packs a little more QPF than the ECMWF and the Canadian GEM. Shearing vort energy, limited QPF, a progressive system and high pressure to our northeast supplying dry air are also limiting factors for more appreciable accumulating snows. Opted for Chance-level PoPs across CT into western MA where the best chance for limited/minor accumulation may be on Tues with up to a couple inches of snow here, tapering to slight chance further to the north and east. NBM-based snow probs also support a light/minor accumulation of snow mainly into CT, western MA and central/southern RI. Drier air eventually wins out and shifts precip axis into our far southern waters Tues night.
Highs mid 20s to the lower-mid 30s on Tues, with lows mid teens to mid 20s.
Wednesday into Wednesday Night:
High pressure to re-build back into SNE for midweek. Despite dry weather, still some RH left behind supporting partly to mostly cloudy conditions and onshore NE flow. Highs upper 20s to the mid upper 30s with lows upper teens to mid 20s.
Thursday into Friday:
Models showing a deepening cyclone near the coastal mid-Atlantic and Carolinas on Thurs, moving eastward mainly south of 40N latitude. It remains to be seen if SNE will see any (fringe) impacts from this progged cyclone, as there's significant latitudinal spread in low centers. In terms of the operational models, the ECMWF is furthest south and would offer a continuation of dry northerly flow. The GEM and more so the GFS (furthest north/somewhat closer to SNE) would bring precip to our southern roughly third of the forecast area. Will need to keep tabs on this system and its developments, but at the moment ensembles presently support a miss or at worst a glancing blow to our southern areas.
System pulls away Thurs night with high pressure building back in for Friday supporting dry weather.
Temperatures project around seasonable levels for late-week.
AVIATION /18Z SATURDAY THROUGH THURSDAY/. Forecaster Confidence Levels.
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
18z TAF Update:

VFR. Strong gusty NW winds developing today, and lingering through Sunday. Winds diminish Sunday night.
KBOS TAF . High confidence in TAF.
KBDL TAF . High confidence in TAF.
Outlook /Monday through Wednesday/ .

MARINE.
Gusty west to northwest winds continue 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. Decided to issue Freezing Spray Advisories for portions of 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: Low risk for gale force winds with gusts up to 35 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. Local visibility 1 to 3 nm.
Tuesday: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain, slight chance of snow. Visibility 1 to 3 nm.
Tuesday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Local visibility 1 to 3 nm.
Wednesday: Winds less than 25 kt. Seas up to 5 ft.
