SYNOPSIS
Scattered showers and perhaps a rumble of thunder tonight give way to a mild Monday. A backdoor cold front will bring cooler temperatures Tuesday and Wednesday. The greatest risk for a period of showers will be Tuesday night into Wednesday morning.
Temperatures for late this week and next weekend are uncertain given the positioning of a backdoor cold front...but may end up on the cooler side especially along the coast. Another chance for a period of showers also arrives sometime next weekend.
NEAR TERM /UNTIL 6 PM THIS EVENING/
While it took some time for the clouds to burn off this morning, abundant sunshine has allowed temperatures to warm into the 60s to near 70F this afternoon. With a few hours left before sunset, it's likely that temps continue to warm a few degrees thanks to mid level ridging and healthy 850mb temps (exceeding 10C) centered over the region. Mainly clear skies will give way to increasing cloud cover this evening as the ridge begins to break down. Convection over central and northern New York will ride the ridge axis, leading to some spillover shower activity across western southern New England early this evening. A few rumbles of thunder are possible across western MA between 22 and 00Z this evening, but instability is rather sub par for thunderstorm activity to maintain strength as showers creep into our CWA, with CAPE around 100J/kg confided to our NW zones.
As ridge breaks down, weak cold front will seep south across the region tonight, which will generate some shower activity through 03/06Z from north to south. QPF will be rather spotty with these frontal showers, generally less than 0.10", so the greatest impact from this front will be decreasing dewpoints; which, aided by a wind shift from the SW to the NW, will drop from the high 50s to the upper 40s north of the MA Pike by daybreak.
Given anomolously high dewpoints for this time of year, overnight lows will be starkly different compared to the last week or so, generally bottoming out in the mid 50s. Given SW flow early this evening and small dewpoint depressions, expecting fog to form across the Cape, Islands, and far SE MA, but aforementioned wind shift and drying flow should keep fog well south of the I-90 corridor/Boston Metro area.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/
Ridge restrengthens tomorrow and broadens, building back towards the west, which will keep very mild temperatures aloft pinned over our area; 925mb temps will climb towards 16C in the CT River Valley! With morning fog and stratus burning off by 15/16Z, we should see very mild temperatures develop, particularly across the interior, but early afternoon as highs surge well into the 70s to perhaps 80F in places like Hartford and Springfield. Given weak pressure gradient, seabreeze development looks like a lock, with climatology telling us it will develop between 14-16Z tomorrow, so, as is usually the case in April, the immediate coastline will be significantly cooler than inland zones, with Boston proper struggling to warm into the low 60s! The only potential snag to temperatures tomorrow would be, as we saw on Sunday, a pesky cloud deck that struggles to erode, but given the high sun angle as we head into the final days of April, hedging our bets that partly cloudy skies will support optimal daytime heating. Given the expected temperature gradient, derived temperatures using the NBM50th percentile away from the coast, and the CONSSHORT for the immediate coastline.
A seasonable night is in store for Monday night as dewpoints continue to drop into the 40s area wide. With light and variable winds, there is a distinct possibility that patchy fog will develop, especially in CT and RI where dewpoints are a bit slower to dry out.
LONG TERM /MONDAY NIGHT THROUGH SUNDAY/
Key Points...
* Cool Tue & Wed with highs in the 50s coast & 60s inland * Main threat for a period of showers Tue night into Wed am * Generally dry Thu & Fri...but large spread in potential high temps * Another round of showers possible sometime this weekend
Details...
Tuesday and Wednesday...
High pressure across eastern Canada will result in an onshore flow and cooler temperatures Tuesday and Wednesday. Onshore flow will hold highs into the 50s along much of the coast and 60s further inland for both afternoons
In fact
the immediate eastern MA coast may see high temps only in the lower 50s.
The other issue will be for a round of showers mainly Tuesday night into Wednesday morning. Shortwave and some instability to our west will allow showers and possibly a few thunderstorms to develop across NY State Tue afternoon. Enough westerly flow aloft should allow some of this activity to survive into our region sometime Tuesday night into Wednesday morning. The activity will be on a weakening trend given our stabilizing marine environment...so for now did not include thunder but later shifts may have to take an other look.
Thursday and Friday...
An upper level ridge axis will again build to the west of southern New England. As this happens will have to watch for some shortwave energy to dive southward from the Canadian Maritimes. This may be enough to send a backdoor cold front southward across southern New England. The ensembles indicate a large spread in the potential outcomes and temperatures. If this front remains to our north high temps will be well into the 70s...but if it does come through like some of the 12z guidance suggests highs will be held in the 50s and 60s. We think much of this time may feature dry weather with the lack of synoptic scale forcing.
Next Weekend...
Approaching shortwave/cold front may bring a round of showers to the region sometime later Sat into Sun...but timing is uncertain given this is a 6-7 day forecast. Thinking temps may end up on the cooler side given the potential for onshore flow...so thinking mainly highs in the 50s and 60s coolest readings most likely on the coast.
AVIATION /19Z SUNDAY THROUGH FRIDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
18Z Update...
Through tonight... Moderate confidence in fog formation
Scattered showers and an isolated rumble of thunder possible this evening, between 22-03Z. Generally VFR conditions through 03Z with low end VFR to MVFR cigs developing behind departing showers away from the Cape and Islands. IFR with localized LIFR likely as fog forms on the Cape/MVY/ACK after 06Z tonight.
Winds SW becoming NW overnight. Gusts to 15kt possible through early evening, generally less than 10kt thereafter.
Tomorrow... High Confidence in Trends
MVFR/IFR may persist through ~15/16Z but will eventually improve to VFR at all terminals by mid day. Winds NW across the interior but a seabreeze will develop along the coast, from the E/ESE along the eastern MA coast and from the ESE/SE around Narragansett Bay. Winds around 10kt expected.
Tomorrow Night..
Mainly VFR with localized MVFR in widely scattered shower activity. Winds generally light and variable in direction.
KBOS TAF...High confidence in TAF.
VFR to MVFR behind scattered showers this evening, between 23-03Z. Expecting fog to stay well south of the terminal as the winds shift from the SW to the NW overnight. Seabreeze tomorrow with NE winds by 13Z and ESE winds by 16Z. VFR redevelops quickly tomorrow morning.
KBDL TAF...High confidence in TAF. Scattered showers this evening between 22Z and 03Z, an isolated rumble of thunder is possible but confidence is much too low to include in the TAF.
Winds SW becoming NW overnight and maintaining direction through Monday. VFR through the period with a chance for MVFR late Monday evening.
Outlook /Monday Night through Friday/...
Monday Night: Mainly VFR, with local MVFR possible.
Tuesday: Mainly VFR, with areas MVFR possible.
Tuesday Night: Mainly MVFR, with local IFR possible. Chance SHRA.
Wednesday: MVFR/IFR conditions possible. Breezy. Chance SHRA.

MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Through Monday... High confidence.
Widely scattered showers possible this evening with a very low chance of a rumble of thunder across the waters. Fog development likely for the near shore waters around the Cape/Islands/south coast with SW winds shifting gradually overnight to the NW.
Winds continue to shift on Monday with seabreeze development; from the ESE along the eastern MA coastline and the SSE along the south coast. Regardless of wind direction, winds generally less than 10kt with gusts to 15kt. Seas mainly 3ft or less all waters.
Outlook /Monday Night through Friday/...
Monday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Patchy fog.
Tuesday: Winds less than 25 kt.
