Area Forecast Discussion National Weather Service Boston/Norton MA 913 AM EDT Sun Jun 13 2021

SYNOPSIS. Weak high pressure brings mainly dry conditions today. A warm front approaches tonight, bringing showers. A cold front will bring showers and possible thunderstorms Monday into Monday night. Periods of showers possible into Tuesday. High pressure with dry weather and seasonable temperatures return Wednesday into Thursday. Turning warmer late in the week ahead of the next cold frontal passage around Saturday.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

915 AM Update .

Previous forecast is on track with beautiful weather to close out the weekend. High pressure located to our southeast will keep the forcing/moisture for any precipitation well to our west today. Southwest flow around the high pressure system will allow for warmer temperatures than yesterday. 850T near +12C along with partly to mostly sunny skies should allow many locations to see afternoon high temperatures top out in the lower 80s. Humidity levels will be quite comfortable as well for this time of year.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/. The majority of our weather will move into our region during this time period. The low pressure should move from PA into northern New England. Expecting widespread showers to arrive from the west, especially after midnight into Monday. Mid level lapse rates are marginal to support thunderstorms and with precipitation ongoing early Monday, there may not be enough time to generate much instability. Most of the convective parameters are favorable for at least embedded thunderstorms across the western half of southern New England. Not overly concerned about severe weather. Although with precipitable water values around one inch, will need to monitor for locally heavy downpours. Near to slightly below normal temperatures expected.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Highlights:

* Unsettled with periods of rain Monday night into Tuesday, most widespread on Monday night.

* Seasonable and dry Wednesday and Thursday.

* Turning warmer (low-mid 80s highs) Friday and Saturday, with showers/t-storms possible with a cold frontal passage around Saturday. Details:

Monday Night through Tuesday Night:

Longwave trough aloft to set up across NY or interior western New England by Mon night, with the mean trough axis gradually translating eastward through Tues night. Most of the deterministic 00z guidance offers multiple vorticity maxima/weak shortwaves rotating around the broader longwave trough through this forecast period, features which don't have much temporal or spatial consistency across models as yet.

All in all, a generally unsettled period with a few opportunities for rain. Rain amounts don't appear to be overly substantial, both from a deterministic and probabilistic sense (low probs for 24-hr rains AOA 1"). Rain, possibly with a few rumbles of thunder from possible weakened daytime convection from eastern NY, move across Southern New England Monday night into early on Tues. The Mon night into early Tues timeframe looks to be the wettest. Wet weather then looks to continue into Tues as well, but due to the varied handling of timing individual vort maxima across the models, confidence in the timing of rains on Tues is on the low side. So for Tues have therefore kept PoPs more broad-brushed at Chance levels, with decreasing PoPs toward dry by Tues night.

Temperatures are generally seasonable. Highs in the upper 70s Tues, with lows Mon and Tues nights in the mid 50s to lower 60s.

Wednesday and Thursday:

Dry weather then returns to Southern New England by midweek with cyclonic flow/troughing aloft and surface ridge in place. Cooler than average 850 mb temps (starting around +9 to +11C, cooling to around +6 to +9C by Thurs) but really just translates to a pleasant midweek stretch weather-wise. Expect lots of sun during the day and clearing at night. Haven't hit this too hard in the forecast but depending on how much rain we do get, a potential for radiational fog during the overnights could exist given favorable clear skies, light winds and surface moisture fluxes coming out of the Mon-Tues rainy period. Did note the earlier 12z ECMWF closed off a low near the mid-Atlantic Thurs which may bring a weak coastal low just offshore; would just lead to clouds and showers for Cape Cod Thurs- Thurs night but this seems like an outlier with little support from its ensemble or other non-ECMWF guidance.

Friday through Saturday:

Troughing aloft transitions to shortwave ridging by late in the week into the early weekend. Expect a warming trend to temperatures Fri and Sat back into the lower to mid 80s, as 850 mb temps climb back into the mid teens Celsius on increasing SW flow. Dewpoints start to climb back into the lower 60s, so humidity levels start to turn less comfortable, but not overly oppressive.

Friday's looking mild but dry. Later Fri night into Sat, a pretty robust shortwave trough and associated frontal system brings our next chance for precip. Customary timing biases apparent between the ECMWF and the GFS, with the GFS being more progressive with rain/thunder starting as soon as Fri overnight while ECMWF brings rains no sooner than Sat afternoon. Strength of the trough and height falls could favor thunder and will mention in the forecast for Saturday, but the uncertainties in timing will need to be resolved (e.g. a frontal passage during the daytime would favor more thunder than an overnight/early AM one).

AVIATION /13Z SUNDAY THROUGH THURSDAY/. Forecaster Confidence Levels.

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

12z TAF Update:

Today . High confidence in ceilings. Moderate confidence in KBOS sea breeze.

VFR. Low risk for some showers late in the day, mainly across the interior. Wind generally SW at 10 kts. At BOS there is a possibility of a sea breeze around 15Z, which would lead to a SE wind for a few hours, before returning to a SW wind mid/late afternoon.

Tonight . High confidence.

VFR to start, then CIGS lowering to MVFR/IFR from W to E after 06Z. E coastal MA may remain VFR through 12Z.

Monday . MVFR/IFR conditions across the western half of southern new England. VFR likely farther east. Breezy. SHRA likely, with a chance for a few TSRA.

KBOS TAF . Moderate confidence in TAF. Sea-breeze may develop by 16z but not certain on development and how persistent it may be.

KBDL TAF . High confidence in TAF.

Outlook /Monday Night through Thursday/ .

Monday Night: Mainly VFR, with areas IFR possible. SHRA likely.

Tuesday: VFR. Chance SHRA.

Tuesday Night: Mainly VFR, with local MVFR possible. Slight chance SHRA.

Wednesday through Thursday: VFR.

MARINE. Forecaster Confidence Levels.

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

Short Term /through Monday/ . Relatively light winds and seas across the waters through Monday. Local sea breezes possible today nearshore, otherwise S to SW flow. Winds becoming S to SE Monday as a warm front approaches the waters. Reduced visibility in heavier showers, with a low risk for thunderstorms tonight into Monday.

Outlook /Monday Night through Thursday/ .

Monday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Chance of rain showers.

Tuesday: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers.

Tuesday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Slight chance of rain showers.

Wednesday through Thursday: Winds less than 25 kt. Areas of seas approaching 5 ft.
