Area Forecast Discussion National Weather Service Boston/Norton MA 1239 AM EST Sat Feb 22 2020

SYNOPSIS.

While dry weather persists this weekend, above normal temperatures return Saturday, and particularly Sunday when many locations reach the 50s by afternoon. Unsettled weather will move in from the southwest as several disturbances cross the region through the middle of next week. There may be periods of rain starting Monday night, but may also see some periods of light snow or a wintry mix during each night well inland. Conditions may turn drier toward the end of next week, but may also bring much colder temperatures.

NEAR TERM /UNTIL 6 AM THIS MORNING/.

1235 AM Update .

High pressure centered to our south will maintain clear skies and light southwest winds very early this morning. Enough decoupling in the typical spots will allow temps to drop into the teens in those areas by daybreak. The areas that typically struggle to decouple in the boundary layer will generally remain in the lower to middle 20s.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/. High pressure neat the Mid Atlantic coast remains in control of our weather Saturday and Saturday night. With winds move from a west to southwest direction, temperatures will start to rise Saturday. Mainly clear skies during this time. Expecting temperatures to return to near to above normal levels during this time, especially during the day Saturday.

Gusty winds are expected, especially along the coast and across the higher terrain of central and western MA, mainly during the afternoon.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. Highlights .

* Dry conditions and mild temperatures continue Sunday into Monday

* Several model guidance members suggest a long wave trough digging across the Mississippi valley by the middle of next week, with the potential for periods of rain and/or nighttime mixed precipitation

* Cutoff H5 system lingers across the Great Lakes through around Wed night/Thu with continued for rain and possibly mixed precip well inland

* May see drier conditions but much colder temps moving in next Friday

Details .

Sunday night and Monday .

Dry conditions should remain in place across the northeast as high pressure pushes off the mid Atlc and SE U.S. coast during this timeframe. Will continue to see SW winds in place, while an Alberta clipper type system moves out of central Canada and another system tries to organize across mid and lower MS valley. Noting H5 heights rising somewhat, running in the 555 to 558 dm across the region. Model guidance suggests highs running around 10 degrees above normal away from the immediate S coast. This translates to highs in the lower 50s across the coastal plain, but will remain lower across the higher inland terrain, possibly as low as the mid 40s.

Monday looks like the pick of the week, with mainly sunny skies at least part of the day and highs from the mid-upper 40s well inland to possibly some readings up to the mid 50s across interior E Mass/N RI and N central/NE CT. Mid and high clouds will start to increase from the W from midday through the afternoon.

Monday night through Tuesday night .

12Z models continue to suggest a big change in the overall North American mid level steering pattern as a trough quickly digs SE out of the Northwest Territories to the E slopes of the Rockies Monday night. Also noting surface low pres across the central MS valley moving NE in the general S-SW steering flow.

Spotty light rain should push across the region Mon night while a warm front begins to lift NE. At this point, the front looks to remain S of the region with a continued nearly zonal flow in place. Should see precip develop overnight Mon night. Still not that organized, with heavier precip remaining S of the region, though a few model members do try to bring more precip in. At this point, kept light precip going for now. There are also some questions whether there could be some mixed RN/SN across the Route 2 area of N Mass into the E slopes of the Berkshires. Temps are forecast to remain marginal, with readings mainly in the lower-mid 30s across the higher terrain and far N Mass.

Went with mainly CHC POPs, but could see LKLY POPs move into the S coast during Tuesday before moving offshore Tue night.

Lows Monday night will range in the mid 20s to lower 30s for most areas except the mid-upper 30s along the immediate S coast, then highs on Tuesday mainly in the 40s, except around 50 across the lower CT valley and coastal plain.

Wednesday through Friday .

12Z model suite continues to signal an H5 long wave trough digging southward across the Mississippi valley by 12Z Wednesday, which could keep mainly rainy conditions in place with the chance for light nighttime snowfall or mixed precip across N central and W Mass both Wed and Thu nights. This will be dependent upon marginal temperatures that may be in place. Still quite a few questions on exact track and timing of this system in the D6-7 timeframe.

At this point, should see mainly light precipitation. Some model members signaling the potential for some heavier precip arriving around Wed night into Thu as some moisture shifts NE out of the Gulf of Mexico. This is a chance for QPF values of 0.5 to 0.75 inches through midday Thu. 12Z GEFS also signaling a PWAT plume of 1-2 SD above normal (around 1 to 1.25 inches QPF), but should move steadily NE.

This mid level cutoff system may continue to deepen as it shifts NE into Quebec. May see the pressure center of the H5 cutoff low decrease to around 510 dm or even lower as suggested by the 12Z ECMWF, though not quite as deep but still rather impressive on the 12Z GFS across the St. Lawrence Seaway by midday next Friday. In any event, could see temps drop quickly Friday night with readings on Sat morning may be well below seasonal levels for late February.

AVIATION /06Z SATURDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels .

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

Today . High confidence. VFR with mainly clear skies. WSW wind gusts of 20 to 25 knots develop late this morning/afternoon.

Tonight and Sunday . High confidence. VFR with mainly clear skies. West to southwest winds of 5 to 15 knots.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF.

Outlook /Sunday Night through Wednesday/ .

Tuesday: Mainly MVFR, with areas VFR possible. Chance RA, chance FZRA.

Tuesday Night: Mainly MVFR, with local IFR possible. Chance RA.

Wednesday: Mainly MVFR, with areas IFR possible. RA likely.

MARINE. High pressure approaches the Mid Atlantic coast tonight through Saturday. Winds become WSW and gusty as a final surge of colder air moves over the waters. Gusty winds continue Saturday, before diminishing Saturday night. Seas may build to around 5 feet across the outer coastal waters in addition. Small Craft Advisories will continue for some of the waters. Winds and seas expected to diminish Saturday night.

Outlook /Sunday Night through Wednesday/ .

Sunday through Sunday Night: Winds less than 25 kt. Seas locally approaching 5 ft.

Monday: Winds less than 25 kt.

Monday Night through Tuesday: Winds less than 25 kt. Chance of rain.
