Area Forecast Discussion National Weather Service Boston/Norton MA 202 AM EDT Mon Apr 29 2024
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 AM THIS MORNING/
Update: 10:00pm
The shower activity continues to fade as mentioned in the earlier discussion. Bulk of the widespread rain is drifting south of the islands and continues to move south-southeast. No major changes to the forecast and the discussion below remains valid.
Please see that discussion below for additional information.
630 PM Update...
* Period of showers this evening with focus western MA/CT * Mild tonight with overnight lows mainly in the 50s
A shortwave coupled with some diurnal heating allowed for a cluster of showers to develop across NY State earlier today.
Northwest flow aloft was allowing these showers to move into western MA/CT early this evening. A few showers may also impact eastern MA/RI for a brief time...but the bulk of them will be across interior southern New England. Low risk for a rumble of thunder, but thinking its not worth inserting in the forecast given areal coverage would be so limited.
The shortwave and associated showers will come to an end by or just after midnight
Otherwise
a rather dry and very mild night is in store for the region. Given anomolously high dewpoints for this time of year, overnight lows will be starkly different compared to the last week or so. Lows should bottom out in the upper 40s to lower 50s near the immediate south coast...but middle to even a few upper 50s are expected for the rest of the region. 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 AM THIS MORNING THROUGH 6 PM TUESDAY/
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 /TUESDAY 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 /06Z MONDAY THROUGH FRIDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
06z TAF Update...
Through 12z... Moderate confidence.
VFR for many, but areas of patchy fog and MVFR Cigs are possible areas south of IJD-PVD-TAN. West-southwest wind becoming north by 12z, wind speeds 6-12 knots, a few gusts possible to 20 knots for the Cape and Islands.
Today... High confidence.
Any lingering lower clouds or fog across the Cape and Islands will dissipate by mid morning, otherwise expect VFR Cigs throughout. Winds are north-northwest 5 to 10 knots across the interior, but a sea breeze develops along the coast 14z to 16z from the east-northeast to the east-southeast along the eastern MA coast and from the south-southeast around Narragansett Bay.
Tonight... Moderate to High confidence.
VFR, localized MVFR within widely scattered showers. Winds are generally light and variable in direction.
Tuesday... High confidence.
VFR east, MVFR west. Showers develop late afternoon across northwestern terminals. Wind direction becomes east-southeast with speeds 8 to 12 knots.
KBOS TAF...Moderate confidence in TAF.
There is uncertainty with how low Cigs will fall this morning, feeling a bit more optimistic that the terminal remains VFR with lowering to 4000ft around 08z to 12z. West-southwest wind will become northerly by 12z, then sea breeze occurs 14z to 16z with a wind direction east-northeast late morning becoming east- southeast by mid afternoon.
KBDL TAF...High confidence in TAF.
VFR. Light west-southwest wind becoming northerly by 12z. Wind direction is generally north through today with winds 10 knots of less. Lowering Cigs tonight to MVFR after 03z/05z.
Outlook /Tuesday 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.
Wednesday Night: Mainly VFR, with local MVFR possible.
Thursday: VFR.
Thursday Night: Mainly VFR, with areas MVFR possible. Breezy.
Slight chance SHRA.
Friday: VFR/MVFR conditions possible. Breezy. Slight 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 /Tuesday Night through Friday/...
Monday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Patchy fog.
Tuesday: Winds less than 25 kt.
Tuesday Night through Wednesday: Winds less than 25 kt. Chance of rain showers.
Wednesday Night through Thursday: Winds less than 25 kt.
Thursday Night through Friday: Winds less than 25 kt. Slight chance of rain showers.
