Area Forecast Discussion National Weather Service Boston/Norton MA 726 AM EDT Sat May 18 2024
SYNOPSIS
Unsettled and cool today with scattered showers. Chance for improvement on Sunday as high pressure begins to nudge in from the southwest. Early summerlike temperatures expected Monday through Wednesday, with the warmest days expected to be Tuesday and Wednesday. A cold front around Thursday offers the next chance at showers or thunderstorms, with temperatures then cooling to more seasonable levels by late in the week.
NEAR TERM /UNTIL 6 PM THIS EVENING/
715 AM Update:
Forecast still looks on track as vertically stacked circulation to our south draws maritime moisture back westward. Unfortunately that will translate to a cool, raw overcast, with intermittent/periodic light rain showers mainly in eastern MA and RI. The showers won't necessarily be present all the time or be a washout, but there will be some to dodge. There is some guarded optimism that western MA could see more of a partly to mostly cloudy look but most everywhere should be socked in with lower clouds. A good day for a bowl of clam chowdah! Temps not likely to go very far from existing values, in the mid 50s to lower-mid 60s.
Previous discussion:
Today we remain under the influence of pesky mid level low to our south that has brought unsettled conditions to southern New England for the last several days. With low to our south, weak shortwave lifts from the Great Lakes into northern Maine by late this evening.
Given southern New England is "sandwiched" between the shortwave and the low, we'll have a few chances for showers today; actually, the first chance for showers is already underway with light precipitation backing in across the Cape and Islands, thanks to persistent ENE. Showers will become more widespread after 15Z today as PWATs surge to >1.0", aided by a weak 925mb jet of 20-30kt draped over eastern MA. General thinking is showers are possible in any location, but will be more widespread east of the Worcester metro area. In fact, the CT River Valley may "luck out" with a primarily dry day as weak high pressure attempts to nudge in from the southwest. While it will a dreary and rather chilly day, with little to no diurnal swing in temps from current obs (in the 50s and low 60s, west), QPF will be minimal, with HRRR ensemble mean QPF around 0.1" across Middlesex and Essex Counties. Should high pressure be able to scatter out a few breaks of sunshine across western MA, could see temps warm briefly into the mid to upper 60s in places like Hartford and Springfield.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/
Pattern of persistence carries through this evening with little change in the synoptic setup through early tomorrow morning.
Shortwave passing to our Northwest may renew shower activity between 00-06Z tonight. Widely scattered shower activity across the eastern half of the CWA will become increasingly sparse after the midnight hour, giving way to a more drizzle-stratus dominated environment by early morning. Temps will pretty much remain stagnant overnight given no change in the pattern with low sin the 50s.
While Sunday previously looked to be a much nicer day for southern New England, there are indications that the influence of onshore flow will persist through the better part of the day across eastern MA and RI, though conditions should improve across CT and western MA as weak high pressure is able to take better hold over the region.
Fortunately, pesky mid level low tracks seaward, which will allow rain chances to decrease significantly by sunrise. As has been the case with many days this Spring, it's likely Sunday is another case of the "haves and have nots", as the CT River Valley breaks out into sunshine and temperatures warm into the low 70s while strong onshore flow pins stratus across eastern MA and much of RI where temps struggle to climb out of the 50s along the immediate coast. It's probably safe to say those in the Boston to Providence corridor are ready to shake this gloomy pattern, but fear not, the long term AFD highlights a significant pattern chance by mid week!
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Highlights:
* Warming temperatures under partly to mostly sunny weather through midweek, with the warmest days likely on Tuesday and Wednesday.
Could have our first 80 degree day in Boston Tuesday and/or Wednesday, with 3 days of lower-mid 80s in Hartford.
* Our next chance for rains is around later Wednesday night or Thursday with showers or thundershowers associated with a cold front.
* Cooling to more seasonable levels for late-week.
Details:
While the general theme of a substantial warming trend to temperatures for the early to midweek period is still valid, today's 00z guidance indicated more potential for continued cloud cover on Monday with higher RH in the 1000-850 mb layer, especially for eastern and southeast New England. Ended up bringing highs down from NBM by a couple degrees for Monday on the basis of this cloud cover, though the temperature forecast has obvious sensitivities to how long clouds linger/scatter out, and that is still a bit unclear.
Kept highs in the mid 50s to mid 60s for the coasts and the coastal plain, but still think highs soar into the mid to upper 70s from central MA/eastern CT westward with less cloud cover.
Warmest days look to be on Tuesday and Wednesday, with full sunshine, southwest breezes and continue dry weather. Relatively strong SW flow should keep sea breezes from making much of any intrusion landwards, so even sites such as Boston and the North and South Shore have a solid chance at reaching 80 degrees, having last occurred at Boston on October 28th of last year. Mid 80s inland seem reasonable on both days. Despite the breezes, both days should feel more reminiscent of early summer with dewpoint temps in the mid to upper 50s.
Dry weather to prevail through Wednesday. Our next chance for showers or thundershowers isn't until a cold front arrives around Wednesday night or Thursday, but the timing and the strength of any thunderstorms are both uncertain. Latest guidance favors Thursday for frontal passage so favored the highest PoP around Thursday but only around 20-30 percent given the uncertainties in timing. Friday appears to be more entrenched in post-frontal colder air, with temps seemingly poised to return closer to late-May climatological levels.
AVIATION /11Z SATURDAY THROUGH WEDNESDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
12z TAF Update:
Today: High confidence in trends, though moderate on timing.
IFR bases were already common over south coastal MA and were starting to lower into MVFR range the PVD/BOS corridor, with VFR in the interior. Continued deterioration anticipated in all areas with MVFR becoming common, and IFR/at times LIFR for central/eastern MA and RI. Scattered hit-or-miss showers fror the eastern which was messaged in TAFs as P6SM -RA, although could be a round of steadier rains developing later today. NE Winds 5-15kt with a few gusts to 20kt possible along the immediate eastern coastline.
Saturday Night...Moderate confidence.
Conditions remain consistently MVFR to LIFR from West to Southeast, lowest on the Cape and Islands. Light showers and drizzle continue through the first half of the evening. MVFR to IFR conditions persist due to pesky onshore flow. Winds continue to blow from the E/ENE gusting to around 10-15kt overnight.
Sunday... Moderate Confidence
Conditions improve from west to east after sunrise from MVFR/IFR to VFR/MVFR. VFR possible for BOS-PVD line, SE after 18Z, though MVFR to hang on across the Cape for the duration of the day. NE winds gusting 15 to perhaps 20kt once again.
KBOS TAF...High confidence in TAF through 00Z. Moderate after this time.
MVFR to deteriorate to IFR late morning/early afternoon, with periodic -SHRA, though may trend towards a steady light rain after 00z. NE flow 10-15kt with the occasional gust to 20kt possible.
KBDL TAF...High confidence in TAF.
Generally VFR but will become borderline VFR/MVFR this afternoon. Showers most likely stay east of the terminal but a stray shower may impact the terminal this afternoon or early evening. Winds NE 5-10kt with gusts to 15kt.
Outlook /Sunday Night through Wednesday/...
Sunday Night through Monday: Mainly VFR, with local MVFR possible.
Monday Night through Tuesday Night: VFR.
Wednesday: VFR. Breezy.
MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.

Saturday... High confidence.
Scattered light rain and drizzle across the waters. Will have visibilities of 3-5 SM. Persistent 15-20 kts out of the NE with gusts up to 20 kts. Seas 1-4 ft across the interior waters and 4-6 ft for the outer.
Saturday Night...Moderate confidence.
Scattered light rain and drizzle anticipated to persist. Will continue to see NE winds at 10-15 kts and gusts around 20 kts.
Visibilities of 3-5 SM and seas 3-6 ft for the outer waters.
Sunday... High Confidence.
Continued NE winds 10-15kt. Seas across the eastern outer waters will remain above 5 feet through the period, but will fall below 5 ft elsewhere. Vsby reductions early Sunday morning should improve through the day.
Outlook /Sunday Night through Wednesday/...
