Area Forecast Discussion National Weather Service Boston/Norton MA 1003 AM EST Sat Jan 25 2020

SYNOPSIS. Low pressure approaching from the Mid Atlantic states will bring a period of heavy rain and strong coastal winds late today and this evening as it tracks across interior southern New England. The precipitation may begin as a bit of freezing drizzle or light freezing rain over the Berkshires late this morning or early afternoon. Mainly dry and mild conditions return Sunday then dry and seasonable for much of next week.

NEAR TERM /UNTIL 3 PM THIS AFTERNOON/. 10 AM Update:

Forecast looks to be holding up pretty well with no major changes needed. Other than a few elevated sites in the Berkshires, most areas in NW MA, northern Worcester County and the CT Valley have warmed over the freezing mark with the inversion having mixed out. Even in the Berkshires, appears there's just enough time for further warming to really mitigate any threat of freezing drizzle/freezing rain in most areas. Otherwise, temps will be slow to warm into the low to mid 40s under overcast.

Looking ahead, frontal rains (perhaps embedded with a rumble or two of thunder towards SE MA and the coastal waters, where about 150-300 J/kg of elevated CAPE is progged) still look on track. Timing still looks to be ~20-21z towards Hartford County and then lifting NNE through 03z - essentially a late-afternoon to mid-evening period of greater impact, with a period of heavy rains likely to accompany these frontal rains. While it is moving quite rapidly, rain totals of up to an inch in a 3-hr timeframe could lead to some localized urban/poor drainage flooding. Easterly low- level jet increases markedly towards SE MA, southern RI and the E/SE coast of MA - NAM/GFS consensus winds at 950 mb is around 50-55 kt. Though we'll continue to monitor the winds, bulk of this jet still is locked up in the inversion, and it may take some possible thunder to tap into these stronger winds. May opt to add possible gusty winds in thunder with forthcoming update, but not imminent as yet.

Previous Discussion .

Widespread stratus across SNE as moist easterly flow in place. Main concern for the morning and early afternoon period is the potential for some light freezing drizzle/rain across the Berkshires. Some of the guidance is suggesting very light QPF this morning in weak and shallow warm advection which would likely be drizzle given dry air in the mid levels. Temps in the Berkshires will be near freezing this morning, so there is a some risk for light freezing drizzle if any precip occurs.

Expect temps to be mostly above freezing as light rain develops this afternoon in western New Eng. However, the coldest hi-res guidance is indicating temps hovering near freezing in the Berkshires so will have to monitor this closely. Confidence not high enough for any winter weather advisories as temps expected to be be above freezing.

Heavier rainfall will remain to the west through early afternoon.

SHORT TERM /3 PM THIS AFTERNOON THROUGH 6 PM SUNDAY/. Mid afternoon through tonight .

Potent mid level shortwave lifts NE through SNE this evening. Ahead of the shortwave a 50-60 kt low level jet develops and moves across the region which will advect PWATs up to inch into SNE. The low level jet combined with strong low level convergence along a triple point low will bring a period of heavy rainfall to SNE late afternoon and evening. This will be a quick hitting storm with most of the rainfall in a 3-6 hour period between 21-06z from west to east. Total rainfall of 0.75" to 1.50" expected but 0.50 to 1 inch of rain may fall in a 3 hour period resulting in localized urban and poor drainage flooding. The heaviest rainfall will be favored in the Worcester hills and east slopes of the Berkshires with E/SE flow enhancing upslope in these areas. In addition, soundings show some elevated instability above the frontal inversion with up to 200 J/Kg of MUCAPE. So an isolated t-storm is possible, mainly across RI and SE MA this evening as the low level jet moves through. The rain ends this evening in the west and around midnight in the eastern MA.

Regarding strong wind potential with the low level jet, a strong low level inversion will preclude the strongest gusts from reaching the surface. Taking about 50-60 percent of the low level jet suggests wind gusts 30-40 mph are possible, focused across SE MA and Cape Cod as temps briefly rise to near 50 degrees. Winds quickly diminish before midnight after the occlusion moves through.

A 1 to 2 ft surge is expected along the south coast around the high tide this evening as the low level jet is moving through. Astronomical tides are rather low and no coastal flooding is expected.

Sunday . Surface low will be moving northward through Maine with drier westerly flow across SNE. This will lead to partly to mostly sunny skies developing. However, mid level low will be located across the Gt Lakes with a strong shortwave rotating through western New Eng. Expect more cloud cover in the west along with a few rain/snow showers possible over the higher elevations. Post-frontal airmass remains mild and highs should reach mid/upper 40s, except upper 30s to lower 40s over the higher terrain.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. Highlights .

* Temperatures slowly trending downward through the week.

* Dry and quiet weather. The only exception is across the eastern slopes of the Berkshires late Sunday into Monday where light scattered rain and snow showers are possible.

Details .

Sunday night through Monday .

Partly cloudy skies continue overnight and Monday as moisture is wrapped around the upper low. This low lifts from northern New England Sunday night to the Canadian maritimes by late Monday while a weak shortwave pivots around the trough through southern New England. The combination of this shortwave, cold air advection on NW winds, and solar insolation may allow for some scattered light showers continuing into Monday; best chance lies over the Berkshires in this case. It will be a bit breezy on Monday as well as CAA promotes good mixing . model soundings indicate potential to mix up to 850 mb which may bring 15 to 20 mph wind gusts out of the west. Temperatures at 850 mb should be around -5C leading to highs in the mid 40s . pretty balmy for late January!

Tuesday through Friday .

Another remarkably quiet week looks on tap ahead of us with potential for most locations to see zero precip through Friday. Partly cloudy skies on Tuesday owing to lingering moisture and a weak rotating shortwave will give way to mostly sunny skies Wednesday through Friday as a high pressure ridge begins to build in from the west. Temperatures will trend downward through Thursday as N/NW flow on the downstream side of the ridge brings in colder air, but even so it only brings us to right around normal by Thursday, in the upper 30s. By Friday the ridge axis approaches and we'll see a wind shift begin to bring in milder air ahead of what could potentially be our next weather makes over the weekend. Much too soon to focus on that possibility, though.

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

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

15Z TAF Update:

Short Term /through Sunday/ .

Through tonight . Moderate confidence. Generally widespread MVFR through 18z (IFR towards the Cape), then more of a widespread IFR by late-afternoon to mid- evening. This occurs as moderate to heavy rainfall moves across western New Eng 21-00z and across eastern New Eng 00-04z. Possibility of LIFR ceilings in the rains as well. Rain ends 03-06z from west to east, but areas of IFR/LIFR stratus and fog persists overnight. E winds gusts 25-30 kt along the coast this afternoon peaking around 35 kt this evening, then diminishing and becoming SW overnight. A brief period of LLWS in eastern New Eng this evening as low level jet moves through.

Sunday . Moderate confidence. Areas of MVFR cigs lingering in the morning in the east, otherwise VFR. West winds gusting to 20 kt.

KBOS Terminal . Moderate confidence. A period of moderate to heavy rainfall this evening with good confidence IFR, lower- confidence LIFR. E gusts peaking around 30 kt this evening.

KBDL Terminal . Moderate confidence. A period of moderate to heavy rainfall late afternoon/early evening with mainly IFR, lower-confidence LIFR.

Outlook /Sunday night through Monday/ .

Sunday Night through Monday: Mainly VFR, with local MVFR possible. Breezy.

Monday Night: VFR. Breezy.

Tuesday through Wednesday: VFR.

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

Increasing easterly winds today with gusts 25-30 kt developing, peaking this evening with max gusts 35-40 kt over eastern MA waters where gale warnings have been issued. SCA elsewhere. Winds diminish after midnight. Westerly winds Sun with gusts 20-25 kt. Vsbys reduced in heavy rain and fog late today and this evening, and in areas of fog overnight.

Outlook /Sunday Night through Wednesday/ .
