Point Forecast Updated Thu Jul 7, 2022 6:48am EDT
Slightly cooler than normals temps today followed by more seasonable temps tomorrow. May be a few showers with a weak frontal passage Friday afternoon. High pressure delivers a period of beautiful summer weather this weekend into early next week, with warm days and cool nights, along with comfortable humidity. A cold front brings the next chance for widespread rains around Tuesday or Wednesday.

000 FXUS61 KBOX 071107 AFDBOX Area Forecast Discussion National Weather Service Boston/Norton MA 707 AM EDT Thu Jul 7 2022 .SYNOPSIS... Slightly cooler than normals temps today followed by more seasonable temps tomorrow. May be a few showers with a weak frontal passage Friday afternoon. High pressure delivers a period of beautiful summer weather this weekend into early next week, with warm days and cool nights, along with comfortable humidity. A cold front brings the next chance for widespread rains around Tuesday or Wednesday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 700 AM Update: Adjusted winds/wind directions to better show the anticipated development of onshore winds (sort of a synoptic gradient/sea- breeze hybrid). Overall no significant changes and have otherwise incorporated current observations and blended into the forecast. Shaping up to be a pleasant Thursday under high pressure - enjoy! Previous discussion: Today Surface high pressure shifts east of the region today. This will support a south/southeasterly flow into southern New England. With flow off the cooler ocean waters, expect temps to be around or slightly below normal for early July with high temps topping out in the mid 70s along the coast and upper 70s to low 80s across the interior. Dewpoints generally in the upper 50s will support comfortable humidity levels. Expect increasing cloudiness during the afternoon hours, especially across the western areas.| && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/... Tonight Mainly zonal flow in the mid and upper levels will support another night of quiet weather. Boundary layer winds becomes more southwesterly overnight. This will allow dewpoints to come up a bit before sunrise. Nonetheless, a comfortable evening with lows bottoming out in the upper 50s to low 60s. Tomorrow Temperatures and humidity climb back up tomorrow as low-level southwesterly flow prevails over southern New England. Expect more seasonable temperatures with highs in the low to mid 80s. Weak surface front will push through the region during the mid to late afternoon. This will support a wind shift to the northwest by tomorrow evening. Can't rule out a few isolated to scattered showers as this front slides through the region. Both deep layer moisture and synoptic forcing will be lacking, thus not expecting any widespread or persistent precipitation with the frontal passage. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Highlights: * Lengthy stretch of pleasant, tranquil summer weather with plenty of sun, low humidity and dry weather Sat thru Mon. * Turning warmer and more humid into midweek ahead of a cold front passing through either later Tues or into Wed. Details: Friday Night: Cold front from the daytime hrs Fri will get more of a southeastward push Fri evening into our coastal waters from a shearing-out shortwave moving into northern New England. Short-lived period of higher moisture could support continued generally light rain showers but the frontal boundary more or less passes SE with little fanfare. Decreasing clouds from NW to SE and a SW to N/NE wind shift for the remainder of the evening, with lows in the mid 50s to mid 60s, mildest south, coolest north/northwest. Saturday through Monday Night: Continued generally strong multi-model consensus in a Canadian- origin anticyclone and related ridging/subsidence governing conditions across SNE through much of this period. As much as 2.5 sigma PWAT anomalies support dry weather with comfortable humidity levels ideal for any outdoor plans. It is worth noting the 00z/7th NAM generates a decent slug of QPF into interior CT, RI and SE MA, well north of a sfc low over the mid-Atlantic region but view this as an outlier compared to good consensus for dry weather across the global models/ensemble means. Thus for the weekend, expect full sun and rather deep mixing during the daytime with modest NW to NEly breezes and good radiational cooling at night. Highs mid 70s to lower 80s, with lows in the 50s to near 60. As high pressure settles into the waters south of SNE on Mon, ensuing warm advection pattern should bring warmer temperatures (upper 70s-mid 80s) and SWly breezes. Tuesday and Wednesday: Surface frontal system with weak low pressure will be the focus in this period, but did note more variation across the guidance with regard to the timing. The progressive GFS supports a frontal passage around Tues-early Tues night; on the other hand the ECMWF supports a frontal passage closer to Tues evening into part of Wed. Thus given more solution spread in timing carried Chance-level PoP for showers/t-storms into at least the first part of Wed. Given amplification of the Intermountain West heat ridge in this period, a hedge toward the slower ECMWF idea might seem more appropriate but still plenty of time to sort through the timing over the next few days. Pending timing of the frontal passage, Tues into Wed would feature elevated humidity levels and summerlike temperatures in the middle to upper 80s. && .AVIATION /12Z THURSDAY THROUGH MONDAY/... Forecaster Confidence Levels: Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. 12z TAF Update: Today: High confidence. VFR. Outside chance at MVFR across the ridgelines of the Berkshires later in the day. Most of the FM groups in TAFs are essentially wind direction changes. Winds trend from N to NE/E and eventually SE/S as the day moves on. Thursday night...moderate confidence for VFR except MVFR across CT into western-central MA, dry weather and light S-SE winds. Friday...VFR. Light south/southwest winds. KBOS...High confidence in TAF. N winds trend NE/ENE 14-16z before becoming SE/S late in the day. KBDL...High confidence in TAF. Outlook /Friday Night through Monday/... Friday Night through Sunday Night: VFR. Monday: VFR. Breezy. && .MARINE... Forecaster Confidence Levels: Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. Today through Friday...High confidence Calm conditions expected over the coastal waters over the next 48 hours. Seas range from 1 to 2 feet in the near-shore zones and 2 to 3 feet in the outer zones. Light south/southeast winds today and tonight. Winds becoming more southwesterly during the day Friday. Outlook /Friday Night through Monday/... Winds less than 25 kt. && .BOX WATCHES/WARNINGS/ADVISORIES... CT...None. MA...None. RI...None.
