Point Forecast Updated Tue Oct 4, 2022 3:10pm EDT
Persistent low pressure south of New England will generate gusty northeast winds and periods of rain tonight into Wednesday. 2 to 3 inches of rain can be expected across RI and southeast MA, with localized higher amounts may result in localized urban and poor drainage flooding. Less rainfall is expected across CT into western-central MA. Dry and much warmer weather arrives Thursday and lingers into Friday. Then a cold front crosses the region Friday night, ushering in dry, but blustery and cool weather for the weekend. Dry weather is likely into Columbus Day, along with moderating temperatures and less wind.

000 FXUS61 KBOX 041927 AFDBOX Area Forecast Discussion National Weather Service Boston/Norton MA 327 PM EDT Tue Oct 4 2022 .SYNOPSIS... Persistent low pressure south of New England will generate gusty northeast winds and periods of rain tonight into Wednesday. 2 to 3 inches of rain can be expected across RI and southeast MA, with localized higher amounts may result in localized urban and poor drainage flooding. Less rainfall is expected across CT into western-central MA. Dry and much warmer weather arrives Thursday and lingers into Friday. Then a cold front crosses the region Friday night, ushering in dry, but blustery and cool weather for the weekend. Dry weather is likely into Columbus Day, along with moderating temperatures and less wind. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... * Steadier rain overspreads the region tonight, with localized 3 to 4 inches totals possible through tomorrow morning for portions of SE MA. Surface low pressure associated with a vertically stacked upper level low is centered over southern NJ. That upper low will slowly track towards the 70W/40N benchmark, bringing a period of steadier rain to much of our area. There will be a rather sharp gradient between areas with generally 0.25 to 0.5 inches of rain and areas that receive 1 to 3 inches of rain. The latter areas appear to be mainly across eastern MA, and especially southeast MA including Plymouth county and the Cape Cod Canal. This is where the nose of the mid-level dry slot and low-level jet is, and local research has shown that rainfall amounts tend to overperform due to the jet dynamics. In addition, the Trough of Warm Air Aloft (TROWAL) will help to further boost rainfall rates and even lead to elevated convection or a few rumbles of thunder overnight. Upon coordination with WPC, have used the HREF Probability Matched Mean (PMM) product to boost rainfall towards the 90th percentile of guidance for overnight tonight into Wednesday morning. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... Expect plenty of clouds with steadier rain becoming more showery as the day goes on. Winds remain gusty but should become less blustery by the afternoon as pressure gradient relaxes. Another unseasonably cool day with highs mainly in the 50s and perhaps a few low 60s readings. Going into Wednesday night, skies should start clearing across the northwest zones, so NW MA should dip into the mid 40s but SE MA stay in the 50s under plentiful cloud cover. && .LONG TERM /THURSDAY THROUGH TUESDAY/... Highlights... * Dry Thu and Fri, along with a big warmup * Blustery and cool Fri night, Sat & Sun, then moderating with less wind Columbus Day Details... Persistent low pressure south of New England should finally move farther out to sea Thursday. A weak high pressure should then be in place along the spine of the Appalachians. As this high pressure moves east, looking like a warmer pattern with southerly winds developing into Friday. As is typical for Autumn, this will not last long, with another cold front expected sometime late Friday into Friday night. Overall, there looks to be enough moisture for clouds at times, but not quite enough to result in much precipitation. Kept the forecast largely dry for this portion of the forecast. Temperature-wise, more of a rollercoaster. We should start out with near to above normal temperatures Thursday into Friday, before falling below normal this weekend into early next week. The weak flow Thursday and Friday will likely mean local seabreezes along the immediate coast both days, leading to cooler conditions there. Thinking there will be modest improvement in temperatures from this weekend into early next week. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... Forecaster Confidence Levels: Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. 1920z update... Rest of today...Moderate confidence. Ceilings range from IFR to VFR across southern New England with even LIFR conditions across far southeastern MA and the Islands this afternoon. VFR continues to prevail across far northwest areas that remain dry. Northeast winds continue to gust between 20 and 30 kt during the day today. Isolated gusts to 35 kt possible across the Cape and Islands. Tonight...Moderate confidence Steadier precipitation expected tonight as IFR conditions prevail across much of the region. VFR ceilings will deteriorate to MVFR across the far northwest interior as precipitation continues to pivot northward. Gusty northeast winds continue overnight, again between 20 and 30kt; highest across coastal RI and the Islands. Wednesday... Moderate confidence Persistent precipitation will extend into Wednesday, especially across eastern MA and RI; the heaviest precipitation of the period may be observed Wednesday morning. IFR conditions persist across eastern MA and RI much of the day. Ceilings across the interior will improve from MVFR to VFR as the day wears on. Gusty NE winds will finally begin to subside late Wednesday as winds fall back to between 10 and 20 kt. Wednesday night....Moderate confidence Skies clear from NW to SE with winds becoming lighter at 5 to 10 kt except for 15-20 kt gusts for the Cape terminals. Improving to VFR across interior terminals with MVFR to localized IFR persisting across Cape terminals. KBOS Terminal...Moderate Confidence in TAF. KBDL Terminal...High Confidence in TAF. Outlook /Thursday through Sunday/... Thursday through Friday: VFR. Friday Night through Sunday: VFR. Breezy. && .MARINE... Forecaster Confidence Levels: Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. 320 PM update... Low pressure centered to our southwest continues to generate gusty, gale force conditions across the southern waters as winds gust over 35 kt. Elsewhere, NE winds continue to gust between 25 and 30 kt. Persistent NE flow allows waves to grow to between 7-10 ft outside bays and harbors. Conditions will be hazardous to pleasure craft through at least Wednesday evening. Seas gradually fall below 5 ft overnight Wednesday. Gale Warnings continue across the southern waters with SCAs elsewhere. Outlook /Thursday through Sunday/... Thursday: Winds less than 25 kt. Seas up to 5 ft. Thursday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Friday: Winds less than 25 kt. Friday Night through Saturday: Winds less than 25 kt. Areas of seas approaching 5 ft. Saturday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Sunday: Winds less than 25 kt. && .BOX WATCHES/WARNINGS/ADVISORIES... CT...None. MA...None. RI...None.
