Area Forecast Discussion National Weather Service Boston/Norton MA 1005 PM EDT Mon Oct 2 2023
SYNOPSIS
High pressure west of New England will provide dry and quiet weather for much of this week. Near record warmth on Tuesday and Wednesday. Showers and thunderstorms late Friday into Saturday. Should be drier Sunday into early next week, but it could be breezy at times.
NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
Update: 10 PM...
Forecast continues on track this evening, though did trend overnight lows down a bit cooler do to the quickly falling temperatures, otherwise no major changes necessary during this update.
Cooler spots likely to drop into the low and middle-40s. Have noticed very patchy fog beginning to develop across typical locations that see radiational cooling and fog.
Previous Discussion...
Clear conditions persist through the overnight as strong mid level ridging and surface high pressure continues to build into southern New England. Previous HRRR smoke forecasts performed poorly during the daylight hours on Monday, such that any smoke that was previously expected over the region this evening and tonight, which would perhaps have a mild influence on radiational cooling, was removed from the forecast.
In addition to the removal of smoke in the near term forecast, lower than forecast dewpoints have developed, thus, trended dewpoints towards the lower bound of guidance, namely using the NAM. Dewpoints in the 40s and low 50s will act as the lower bound for temperatures overnight, with decent radiational cooling expected as winds decouple under clear conditions. Radiation fog is expected to develop across our fog prone interior localities, especially along the CT River Valley and southeast MA.
SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/
This beautiful stretch of weather, really by any time of year's standard but especially early October, continues into Tuesday.
Temperatures will warm a few degrees either side of 80F for highs; some 10-12 degrees above normal, as synoptic flow turns more WNW tomorrow, allowing 850mb temps of 15-17C to build over our area. Any morning fog will dissipate by 15Z.
Winds are expected to be lighter tomorrow compared to what was observed today given the weak LLJ of 15-25kt draped over southeastern MA and RI, born from the pesky coastal remnant low across the far southern waters, is suppressed even farther south.
Given the HRRR smoke performed so poorly for Monday, and satellite obs provide no reasonable origin for smoke tomorrow, did not include haze/smoke in the forecast. Anticipating it will be a beautiful, bluebird day for the region. The RAP, which performed slightly better on Monday, yields very low smoke concentrations, that would amount to not much more than a slight haze on the low horizon.
Tuesday night will feature similar conditions to Monday night, though will be warmer as dewpoints warm into the 50s and 60s. As with most nights during Fall, River Valley radiation fog is again possible.
LONG TERM /WEDNESDAY THROUGH MONDAY/
Highlights...
* Dry and quiet weather continues through at least Thursday if not Friday. Still mild on Wed, but temps trending more seasonable as we head late into the week.
* Next shot for widespread showers is late Fri into Sat with thunderstorms possible.
* Drier and cooler Sun/Mon.
Details...
Wednesday and Thursday...
The mid level ridge axis that has been/will be controlling our weather of late should be directly over SNE Wednesday morning as is slowly marches east. At the surface the center of the high will be just out ahead of it. This spells very light winds with seabreezes at the coast and subsidence keeping clouds to a bare minimum each day. Temperatures Wednesday will once again be very warm for early October, especially in the interior where highs will get into the low 80s (compared to normal which is around 70). Cooler but still abnormally warm along the coast, in the 70s. For Thursday the airmass moderates a bit as 850 temps drop from 17C to 14-15C allowing highs to cool several degrees, to the mid/upper 70s. There will be a good amount of radiational cooling overnight so the forecast has been trended toward the MOS guidance, in the low to mid 50s for lows.
Friday and Saturday...
A high amplitude trough then digs into the Great Lakes by Saturday, so in the 12-24 hours leading up to that we'll see winds turn out of the SW and direct a very moist airmass into the region ahead of the trough. This means increasing cloudcover Friday, with potentially even some warm frontal showers as early as Friday afternoon.
Guidance at this point remains split as to how quickly warm advection precip arrives but at this point it is looking like we won't escape with a completely dry day on Friday. The wettest period looks to be Friday night and Saturday, continuing our tradition of wet weekends this year. Some guidance indicates a few hundred J/kg of CAPE ahead of the cold front along with strong bulk shear so we may be dealing with some thunderstorm activity, but too soon for details at this juncture. Good news is that the second half of the weekend looks to be post frontal and drier (though still under cyclonic flow). Regardless of precip chances, temperatures will likely be taking quite a drop for the second half of the weekend.
AVIATION /02Z TUESDAY THROUGH SATURDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
00Z Update...
Through Tuesday morning...
VFR, with the exception of patchy IFR/LIFR at fog prone terminals like BAF and BDL just prior to sunrise Tuesday.
Otherwise, N/NE winds this afternoon of 10-15kt diminish overnight as they turn W/SW for by early morning.
Tuesday and Tuesday night... VFR as patchy morning fog burns off by 15Z. Winds generally W/WSW, less than 10kt.
KBOS Terminal...High confidence in TAF. E/ENE winds gusting to 15 kt today diminish overnight becoming WSW for Tuesday, less than 10kt. VFR through the period.
KBDL Terminal...moderate confidence in TAF. VFR through midnight tonight, patchy fog may develop by sunrise yielding IFR/LIFR conditions but confidence is low to moderate. Winds generally light, becoming W/WSW for tuesday.
Outlook /Wednesday through Saturday/...
Wednesday through Thursday: VFR.
Thursday Night: Mainly VFR, with local MVFR possible.
Friday: Mainly VFR, with areas MVFR possible. Slight chance SHRA.
Friday Night: MVFR/IFR conditions possible. Breezy. Chance SHRA.
Saturday: Mainly MVFR, with areas IFR possible. Breezy. SHRA likely, isolated TSRA.
