Area Forecast Discussion National Weather Service Boston/Norton MA 1007 AM EST Tue Jan 21 2020

SYNOPSIS.

High pressure will build over southern New England for most of the week, bringing dry weather and moderating temperatures. There is the potential for a coastal storm this weekend, but uncertainty exists in regards to timing and precipitation types.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

10 AM Update .

Nudged down high temperatures for today a few degrees based on the latest obs as we are just a bit too warm. Otherwise forecast remains on track. Light ocean effect snow showers still possible across Cape Cod. Best opportunity for this is across the outer Cape.

Previous Discussion .

High pres in control. Column is rather dry and sunshine will give way to increasing high clouds later today from the north as mid level shortwave moves into northern New Eng. The one caveat for today is potential for ocean effect clouds and flurries/snow showers for the outer Cape. Steep low level lapse rates over the ocean and delta T from SST to top of the shallow boundary layer around 17-18C so enough low level instability for clouds and perhaps a few flurries or snow showers. N wind trajectory favors the outer Cape and some of the hi-res sources are indicating some light QPF so have indicated chc pops here. Low risk for a coating to one half inch for the outer Cape. Low level cold air remains in place with 925 mb temps around -10C so expect highs 25 to 30.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. Tonight . Any ocean effect clouds or flurries over the outer Cape will dissipate as low level moisture decreases and inversion lowers. Otherwise, some mid/high clouds expected to move through the region, especially across northern and eastern MA as shortwave rotates SE through the Gulf of Maine. Potential cloud cover may have some impact on low temps so went a bit above MOS guidance with temps mostly in the teens, with some single numbers in western MA.

Wednesday . Mid level shortwave moves well east of New Eng with ridging building into the region. High pres will remain in control at the surface. Expect lots of sunshine with light winds and moderating temps. Highs will range through the 30s.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. Highlights .

* Milder, above normal temperatures Thu/Fri with continued dry weather

* Coastal storm this weekend brings rain/snow chances Sat/Sun, favoring more rain than snow along the I-95 corridor, but uncertainty in precip type remains.

Details .

Wednesday night through Friday .

Dry, quiet weather rounds out the very quiet work week. This under a building ridge of sprawling high pressure. A noticeable change from the first half of the week will be the rebounding temperatures. We'll be back toward normal and then some as low and mid level flow comes out of the S/SW on the back side of the high and draws in milder air. A subsidence inversion under the high pressure will keep mixing very shallow (model soundings indicate to around 950 mb); should see highs in the low to mid 40s each day. A weak gradient may allow for sea breezes keeping things cooler along the coast. Lows dip into the 20s/low 30s Thursday and Friday nights, colder on Wednesday night (teens) due to light winds, little cloud cover, and resultant radiational cooling, in addition to the colder airmass we start with.

Saturday and Sunday .

For Saturday we are becoming increasingly confident that our stretch of quiet weather will come to an end, though details regarding exact onset time and precip type are less certain. A digging 500 mb trough and sfc low over the Ohio Valley move into the mid-Atlantic, generating a coastal system that will move east in the vicinity of southern New England from Saturday through Sunday, perhaps even lingering into Monday. At this point the best chance for snow continues to be in the interior, especially the higher elevations given the marginal/warm antecedent airmass and the expected low track too far north to bring with it the cold air necessary for snow to the coast. Wintry precip, however, is certainly still a possibility anywhere. EC ensemble probabilities of >1" snow continue to exhibit a SE creep over the last several model runs, so plenty is still left to be seen in regards to any snow potential for the rest of southern New England. Blocking high pressure in eastern Canada will play a role, potentially assisting with colder air, and slowing the low as it ejects. This will be a very wet system (QPF totals up to over 1" possible), and slow moving, with potential to drop a significant amount of snow in interior southern New England that would be disruptive and impactful. Stay tuned.

Monday .

Still some question as to how quickly the weekend system exits but Monday should be dry or drying out as the low exits to the northeast and high pressure builds in from the west.

AVIATION /15Z TUESDAY THROUGH SATURDAY/. Forecaster Confidence Levels .

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

Short Term /through Wednesday/ . High confidence.

VFR. Patchy ocean effect MVFR cigs and a few -SHSN may develop today after 12z over the outer Cape.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF.

Outlook /Wednesday Night through Saturday/ .

Wednesday Night through Friday: VFR.

Friday Night: Mainly VFR, with local MVFR possible.

Saturday: Mainly VFR, with areas IFR possible. Breezy. Chance RA, chance SN.

MARINE. Short Term /through Wednesday/ . High confidence.

Diminishing wind/seas becoming light today with light winds/seas continuing through Wed as high pres in control. Scattered snow showers possible today and this evening over waters east of Cape Cod.

Outlook /Wednesday Night through Saturday/ .

Wednesday Night through Thursday: Winds less than 25 kt.

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

Friday: Winds less than 25 kt. Local rough seas.

Friday Night: Winds less than 25 kt. Rough seas up to 9 ft.

Saturday: Winds less than 25 kt. Rough seas up to 9 ft. Chance of rain.
