Area Forecast Discussion National Weather Service Boston/Norton MA 641 PM EST Wed Jan 22 2020

SYNOPSIS. High pressure will be in control through the end of the week bringing dry weather and moderating temperatures. A storm is expected to impact the region Saturday into Sunday with rain near the coast and snow over the high elevation interior. Some light snow showers are possible late on Sunday into early Monday as the storm exits, then mainly dry and seasonable conditions into Tuesday.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/.

630 PM Update .

No changes in the latest update. Forecast remains on track. Will need to monitor the potential for radiation fog development across the interior after midnight. Have not included in the latest update, but some high resolution guidance hints at this possibility. Held off as Bufkit soundings keep the lower levels dry.

Previous discussion .

Tranquil weather tonight with 1030 mb high pressure cresting over the region. Big temp differences between the urban/City areas vs suburbs overnight given light winds, dry airmass and mainly clear conditions. Given this derived min temps overnight from MOS and bias corrected MOS.

SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/. Thursday .

Deep layer ridge over the region Thu with plenty of mid level anticyclonic flow to support dry weather and mostly sunny conditions (other than some cirrus from time to time). Airmass continues to modify so temps not as cold as today. Despite subsidence inversion limiting blyr depth/mixing, modest WSW wind combined with airmass continuing to modify will support highs of 45-50. Given this derived highs tomorrow from the warmer MOS and bias corrected MOS data sets. These temps will be about 10-15 degs above normal.

Thursday night .

Another quiet/tranquil night with dry weather prevailing. Not as chilly as tonight as airmass continues to modify. Still good radiational cooling conditions with large temp differences between urban areas vs suburbs. Weak frontal boundary approaches from the north toward Friday morning. Only sensible weather will be a wind shift to the NE and cool shallow air beginning to advect southward.

LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/. Highlights .

* Dry weather Friday with above normal temperatures.

* Coastal storm this weekend initially bringing a cold rain for much of southern New England. Best opportunity for snowfall is across the interior where things begin as a wintry mix before transitioning to rain/snow.

* Scattered snow showers across the region late on Sunday into early Monday.

* Slightly cooler temperatures after the weekend.

Details .

Friday into Saturday AM .

Ridge axis initially in place over New England, while a cutoff low is situated over the Mid Mississippi River Valley. The ridge will slowly build into northern New England and Quebec by early Saturday. The cutoff upper low will slowly lift northeastward into the Ohio River Valley. A weak shortwave will lift through New England on Friday. At the surface a weak backdoor front will shift winds to the north/northeast and usher more in the way of cloud cover and cooler readings in comparison to Thursday. Temperatures range from the mid 30s to the mid 40s.

Cloud cover will continue to increase as the cutoff system moves toward the region late on Friday into Saturday. Expect light southerly/southeasterly winds overnight advecting 0 to +5 degree Celsius 850 hPa air into the region. This will continue the trend of warmer overnight temperatures (in comparison to the past couple of days). Readings range from the mid 20s across the Berkshires to the mid 30s along the coast.

Saturday into Sunday AM .

The cutoff low continues lifting northeasterly into the Great Lakes. The surface low associated with the cutoff will remain over the central Great Lakes, but a secondary low will develop lee of the Appalachians. Deterministic and ensemble guidance continues to trend warmer with this system and slower with the onset of precipitation. Have slowed down precipitation chances, and this is likely due to the drier air in place ahead of the incoming system.

The secondary surface low track has been trending with a more westerly track, which advects +5 to +8 degree Celsius 850 hPa air into the region. However, some locations across the interior will see colder air locked in the lower levels. The current thinking is that interior areas will see a wintry mix become a mix of rain/snow, while much of the region sees a cold rain. Best opportunity for accumulating snowfall is across the higher elevations at this point in time.

Looks like there will be a good slug of precipitation between roughly 18Z Saturday until roughly 12Z Sunday with the heaviest precipitation Saturday evening. This quick slug of precipitation is followed by the dry slot moving in. Still a good amount of spread in the ensemble guidance across the region with the QPF, so confidence is low to moderate at this point in time. This impacts the snowfall amounts across the higher elevations. Folks will want to stay tuned as if higher QPF amounts are expected some locations could see an impactful snowfall. QPF values vary between 0.75 to 1.5 inches across the region value the EPS/GEFS. Expect strong winds especially over the ocean as the low deepens over the region. Gale force winds are possible late on Saturday into Sunday and headlines may be needed.

Sunday AM through Monday AM .

Model solutions diverge on how quickly the upper level low lifts from the eastern Great Lakes/southern New England into northern New England. The latest ECMWF/GFS are in a similar camp while the GEM is a bit slower. The thermal profile is similar with colder air advecting in aloft (roughly 0 to -5 degree Celsius 850 hPa air). Expect this to bring scattered rain/snow showers gradually becoming all snow showers. Precipitation will be relatively light during this timeframe, and expect little to no snowfall accumulation. Due to the differences have kept a blend amongst guidance.

Monday through Tuesday .

Drier air moving in as the cutoff low exits, but models are spread out on the specific details at this point in time. Have a blend of guidance at this point in time due to uncertainty. Temperatures do appear to be trending downward early next week.

AVIATION /00Z THURSDAY THROUGH MONDAY/. Forecaster Confidence Levels .

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

Short Term /through Thursday/ . High confidence.

00Z Discussion .

VFR through the forecast with high pressure in control. Winds less than 10 knots over the next 12 to 15 hours. Low chance of fog development across the interior as hinted at by SREF probs, the HREF and NAMnest. Have held off from including in the latest update as Bufkit soundings keep the lower levels quite dry.

Winds gradually shifting from the WSW to the W. Expect winds to increase to around 10 knots at ACK, HYA and FMH tomorrow morning.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF.

Outlook /Friday through Sunday/ .

Thursday Night through Friday: VFR.

Friday Night: Mainly VFR, with local IFR possible. Breezy.

Saturday: MVFR/IFR conditions possible. Breezy. Chance RA, chance SN.

Saturday Night: Mainly IFR, with areas MVFR possible. Windy with local gusts up to 30 kt. SN, chance RA.

Sunday: MVFR/IFR conditions possible. Breezy. Chance SHSN, slight chance SHRA.

Sunday Night: MVFR/IFR conditions possible. Breezy. Slight chance SHSN.

Monday: Mainly VFR, with areas MVFR possible. Breezy.

MARINE.

Short Term /through Thursday/ . High confidence.

Light SW to WSW winds and tranquil seas through the period as high pres over the waters.

Outlook /Thursday Night through Monday/ .

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

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

Friday Night: Winds less than 25 kt. Areas of rough seas.

Saturday: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 10 ft. Chance of rain.

Saturday Night: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 14 ft. Rain.

Sunday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Rough seas up to 14 ft. Slight chance of rain showers.

Sunday Night: Winds less than 25 kt. Rough seas up to 11 ft. Slight chance of rain showers, slight chance of snow showers. Areas of visibility 1 to 3 nm.

Monday: Winds less than 25 kt. Areas of rough seas. Local visibility 1 to 3 nm.
