Area Forecast Discussion National Weather Service Boston/Norton MA 209 PM EST Fri Dec 13 2019

SYNOPSIS. Heavy rain overspreads southern New England later tonight into Saturday. Some spots will see a slick commute this afternoon and evening. A period of strong winds is also expected Saturday across the Cape and Islands. Dry and blustery conditions move in on Sunday, then colder air arrives Monday. Another system will bring snow Monday night, then change to a wintry mix along south coastal areas toward daybreak Tuesday. Expect dry conditions late Wednesday and Thursday, with temperatures well below normal on Thursday.

NEAR TERM /THROUGH TONIGHT/. * Slippery travel expected for the evening commute

* Heavy Rain will result in the potential for some river/stream flooding and some urban street flooding are possible, too

Temperatures lingered around freezing in the valleys of interior southern New England this afternoon. Thus the threat of freezing rain continues into this afternoon. Will continue the Winter Weather Advisory until all temperatures are above freezing.

Steadier rainfall will overspread southern New England tonight, with the heaviest rainfall across the eastern half of southern New England after midnight. Many signals for efficient rainfall process late tonight into Saturday. Most impressive is the depth of the warm rain processes, in excess of 10 kft for most locations. Moisture flux convergence at 850 mb is +6 standard deviations for mid December. Wind convergence and speeds are also +3 to +4 standard deviations. It will rain tonight. It is now just a question of how fast it will fall and where.

Majority of the synoptic dynamics favor a period of heavy rainfall across the eastern half of southern New England. Decent frontogenesis at the nose of a strong low level jet. Have some concerns for elevated convection, but not overly confident there will be enough instability to make it a reality. Would not be surprised for a few rumbles of thunder later tonight. Flood Watch will continue as posted.

Strong southerly winds will mean slowly rising temperatures through tonight.

SHORT TERM /SATURDAY/. * Period of southerly 40 to 55 mph wind gusts likely across the Cape/Islands on Saturday

Heavy rainfall should continue through much of Saturday morning. The big question will be how soon does this rainfall move offshore. Thinking a dry slot develops on the backside of a departing low pressure. This should bring rainfall to an end across the eastern half of southern New England during the afternoon hours. Some question above central and western MA, which will be closer to the core of a cold pool aloft. Thinking some showers will persist into the afternoon there, but will not be nearly as heavy.

Impressive low level jet at 925 mb, but stuck above a shallow but strong inversion. Not expecting mechanical mixing to be a huge factor in bringing these speeds to the surface. That pretty much just leaves precipitation drag, particularly if convection develops. Wind Advisory will continue for the Cape and islands.

A 1 to 2 foot storm surge appears reasonable along the south coast during the Saturday morning high tide. This may result in some pockets of splashover/minor coastal flooding. However, do not expect winds or storm surge to result in anything too significant. Will need to consider a Coastal Flood Statement or Coastal Flood Advisory.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Highlights .

* Leftover light rain/snow lingers Saturday night into Sunday morning. Strong northwest winds, especially in coastal areas with gusts from 35 to 45 mph Sunday. Gale warnings in place across the coastal waters Saturday night and Sunday. Another round of wind headlines may be needed Sunday.

* Dry and seasonably cold Monday

* Next system moves in moves in late Monday night through Tuesday evening. Expect another round of snow before becoming a wintry mix which may change to rain for a time along the coastal plain. While confidence continues to increase, but storm track and precipitation types remain uncertain.

* Snow showers may linger into Wednesday with dry conditions elsewhere. Unseasonable cold temperatures Wednesday and Thursday. Details .

Saturday night .

Leftover rain will slowly taper off from S-N from around midnight onward, but may see a mix with snow across the E slopes of the Berkshires. Clouds will linger especially across the interior, though may start to thin out toward daybreak.

Expect winds to shift to W as the strong low pressure moves to the western Quebec overnight. Speeds will increase overnight with the tight pressure gradient, gusting up to 25 to around 30 kt are likely after 08Z across the higher inland terrain and along the coast, with gusts up to 20-25 kt across most other areas.

Temps will fall back to the lower-mid 30s across the higher inland terrain ranging to the lower 40s along the immediate shoreline.

Sunday .

** Strong winds expected **

As the strong low shifts NE toward Newfoundland Sunday, expect the strong wind gusts to continue as the colder air continues to filter in. Will see gusts up to 30-40 kt, highest along the immediate E coast and especially across Cape Cod and the islands.

Temperatures will not rise much, with highs only in the upper 30s to mid 40s, but the winds will be rather strong. Have continued Gale Warnings for the open waters on Sunday, and may need another round of wind headlines across parts of the region as well.

Monday through Tuesday .

**Potential for snow mixing with/changing to rain Tuesday**

Another batch of cold air will swing across the region on Monday. Temps will only reach the upper 20s to lower 30s across the higher inland terrain, ranging to the mid-upper 30s across the coastal plain. Winds will start off gusty across the coastline with gusts up to around 20-25 kt early, but should diminish during the day. The cold temps will run around 5 degrees or so below seasonal normals for mid December.

Clouds will increase from S-N Monday night as another storm system works E-NE out of the south central Plains states. Looks like the low should pass across the interior, but tough call with wide model solution spread on the track and timing of this low. Rather low confidence with this portion of the forecast.

Have carried increasing POPs from SW-NE with light snow to start Monday afternoon. Milder air will start to overrun the cold low level dome, so will see a wintry mix of precip starting along the S coast after midnight Monday night riding up to around the Mass Pike by around 12Z, then should the precip change to rain from SE-NW across central and southern areas during the day. At this point, looks like mainly snow across N central and W Mass, with a rain/snow mix through most of the day across NE Mass southwestward into N RI and CT. Should start to taper off late Tue and Tue night as another batch of cold air works in.

Wednesday through Thursday .

May see some leftover snow showers across E coastal areas and the E slopes of the Berkshires during Wednesday, otherwise mainly dry conditions and cold temperatures in place. Another surge of colder air from the W-NW will bring even colder temperatures but continued dry conditions on Thursday. Fast moving low pressure may push across later Thursday, but still quite a few days to watch this system.

AVIATION /19Z FRIDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels .

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

Short Term /through Saturday/ . High confidence in trends. Moderate confidence in timing.

Through 00Z . Mix of VFR across eastern MA, decreasing to MVFR conditions across western MA and northern CT. Ceilings lowering through the evening push.

Tonight and Saturday . Conditions deteriorate through the night to IFR/LIFR thresholds and persist into at least the first half of Saturday. Heavy rainfall late tonight into Saturday morning, and can not rule out an isolated thunderstorm or two. A period of southerly wind gusts of 35 to 45 knots develops Saturday across the Cape/Islands. Some gusty southerly winds are possible along the coastal plain, too. Elsewhere a fairly strong inversion will keep strong winds aloft. However, LLWS will be a concern.

KBOS Terminal . High confidence in trends. Moderate confidence in timing.

KBDL Terminal . High confidence in trends. Moderate confidence in timing.

Outlook /Saturday Night through Tuesday/ .

Saturday Night: Mainly MVFR, with local IFR possible. Windy with gusts up to 35 kt. Chance RA, chance FZRA, patchy BR.

Sunday: Mainly VFR, with local MVFR possible. Windy with gusts up to 35 kt.

Sunday Night: VFR. Windy with gusts up to 35 kt.

Monday: VFR. Breezy. Slight chance SN.

Monday Night: Mainly VFR, with areas IFR possible. SN likely, patchy BR, FZRA likely.

Tuesday: MVFR/IFR conditions possible. Breezy. Chance RA, chance SN, FZRA likely, patchy FG.

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

Increasing LLJ will result in SW winds of 25 to 30 knots developing tonight. On Saturday, a potent 80 knot LLJ at 925 mb will result in a period of southerly wind gusts between 35 and 45 knots on most open waters, so Gale Warnings are posted. Despite the inversion, given the magnitude of the LLJ, expect some Gale Force gusts to mix down especially if any embedded convection develops. Seas build to between 7 and 13 feet across our open waters.

Outlook /Saturday Night through Tuesday/ .

Saturday Night: Low risk for gale force winds with gusts up to 35 kt. Rough seas up to 15 ft. Areas fog, slight chance of rain. Local visibility 1 to 3 nm.

Sunday: Moderate risk for gale force winds with gusts up to 40 kt. Rough seas up to 15 ft.

Sunday Night: Moderate risk for gale force winds with gusts up to 40 kt. Rough seas up to 12 ft.

Monday: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of rough seas. Slight chance of rain.

Monday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Rain likely, snow likely, freezing rain likely, patchy fog. Areas of visibility 1 to 3 nm.

Tuesday: Winds less than 25 kt. Areas of rough seas. Chance of rain, freezing rain likely, patchy fog.

HYDROLOGY. Thinking there is an elevated risk for flooding issues late tonight into Saturday due to a combination of excessive rainfall and snowmelt. Will need to consider River Flood Watches for some locations, particularly across RI southeast MA where the heaviest rainfall is expected. Poor drainage and urban flooding will also be a concern. This includes locations trying to drain in the ocean, which will be a bit higher due to the proximity to the last full moon as well as from surge.

BOX WATCHES/WARNINGS/ADVISORIES. CT . Winter Weather Advisory until 10 PM EST this evening for CTZ002. MA . Flood Watch from 1 AM EST Saturday through late Saturday night for MAZ004>007-012>024-026.
