NWS Boston/Norton, MA wrote its last area forecast discussion before the first event at Jun 7, 1:34 PM EST, 36 minutes earlier.
Area Forecast Discussion National Weather Service Boston/Norton MA 234 PM EDT Sat Jun 7 2025 .SYNOPSIS... A cold front will bring showers and isolated thunderstorms with pockets of heavy rainfall later today and especially this afternoon. Dry weather returns tonight and continues into Sunday with pleasant temperatures. A few showers are possible on Monday, but the bulk of the rain with the next system will hold off until Tuesday. Dry and warmer weather follows for Wednesday and Thursday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Key Messages... * Areas of fog this morning especially near the south coast * Showers/isolated t-storms with pockets of heavy rain today * Bulk of the rain overspreads the region between 11 am and 3 pm * Highs mainly in the 70s with some upper 60s on the immediate coast Details... Dry weather dominated very early this morning but areas of fog were expanding across the region. Some of the fog may be locally dense especially near the south coast. We do expect visibility to improve in most locations later this morning and afternoon...but fog may flirt with areas near the coast all day. A slow moving cold front approaches from the west later today and will combine with Pwats over 1.50" along with good forcing on the boundary. The result will be band of widespread showers with isolated t-storms that moves across the region from west to east. Outside a few showers into mid morning...the bulk of the rain will arrive from west to east in the 11 am to 3 pm time frame. Given the amount of forcing and high Pwat values some of the showers will contain heavy rainfall. This may result in typical nuisance street flooding...but the environment is not as favorable for the localized flash flooding that we saw yesterday. The instability will be less...generally on the order of 400-800 J/KG. Therefore...we will not be issuing a Flood Watch at this time...but it is something later shifts may need to consider based on radar trends. Regardless...pocket of heavy rainfall and brief poor drainage street flooding are certainly possible. The severe weather threat is also rather low today...given limited instability and lots of cloud cover. Clouds and showers will keep high temperatures mainly in the 70s today...but locations along the coast may only see highs in the upper 60s. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/... Key Messages... * Any lingering showers depart this evening * Otherwise, dry with some fog tonight...lows 55-60 * Partly sunny with highs in the 70 to near 80 on Sunday Details... Tonight... Shortwave and associated cold front will exit the region this evening...taking any lingering showers with it. Otherwise...dry and pleasant tonight and a bit cooler too with lows mainly in the 55-60 degree range. Light winds coupled with leftover low level moisture will likely result in areas of fog developing overnight. Sunday... A brief ridge of high pressure builds into the region. This will result in a mixture of clouds and sunshine and a pleasant end to the weekend. High temperatures on Sunday will be in the 75 to 80 degree range...but cooler lower 70s on the immediate coast with onshore flow. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... Key Messages: * Scattered showers and cooler temperatures Monday and Tuesday * Clearing Wednesday into Thursday with highs reaching the low to mid 80s Details... Onshore flow continues through Monday, allowing for a lengthier period of cooling and for high temps to remain in the mid 60s to low 70s across southern New England. Most guidance is indicating a low moving northeast off the coast to our south on Monday, bringing some scattered showers to the region Monday. Still quite uncertain on the exact track of the low... the ECMWF and NAM are indicating a closer pass to the Cape and Islands, which would bring more rain to southern New England, while the GEM and GFS are favoring more of an offshore solution, which would keep most of the rain over the waters. A warm front is expected to move through Tuesday, placing the region in the warm sector and elevating surface moisture, once again bringing rain chances. With rain looking possible for most of the day, highs are likely to remain in the 70s. A cold front passes through Tuesday night/Wednesday morning, shifting winds back to the west and ushering in some drier air. Drier and clearer conditions likely Wednesday heading into Thursday post-FROPA. With the clearing skies, high temps look to rebound into the 80s for the second half of the week. Lows through the extended period not expected to change much from night to night, remaining mostly in the 50s and 60s across southern New England. Unsettled conditions return heading into the weekend, bringing more chances for showers. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. 18z TAF Update... This Afternoon...Moderate confidence. Generally expect MVFR-IFR conditions. Showers and a few thunderstorms from west to east this afternoon, some containing localized heavy downpours and a low chance for lightning. Light SE winds along the coastline. Light S winds elsewhere. Winds shift to the N late afternoon early evening. Tonight...Low confidence. VFR conditions to work into western MA/northern CT overnight; however, residual low level moisture may allow areas of fog to develop and allow MVFR- IFR conditions to return. MVFR-IFR conditions with localized LIFR conditions east of the CT River with low clouds and areas of FG/BR. Sunday...High confidence in trends but lower confidence in timing. Lingering MVFR-IFR conditions Sunday morning improving to VFR from west to east 14-17z. Will likely take a bit longer for the Cape and Islands. E winds generally at 5 to 10 knots. BOS TAF...Moderate confidence in TAF. Convective showers through 01z where a brief rumble or two of thunder is possible 20z-23z. BDL TAF...Moderate confidence in TAF. Outlook /Sunday Night through Thursday/... Sunday Night: VFR. Slight chance SHRA. Monday: Mainly VFR, with areas MVFR possible. Slight chance SHRA. Monday Night: Mainly VFR, with areas IFR possible. Slight chance SHRA. Tuesday: MVFR/IFR conditions possible. Chance SHRA, isolated TSRA. Tuesday Night: Mainly VFR, with local IFR possible. Chance SHRA. Wednesday: VFR. Breezy. Wednesday Night: VFR. Thursday: Breezy. && .MARINE... Forecaster Confidence Levels: Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent. Today through Sunday...High confidence. A relatively weak pressure gradient will keep winds below small craft advisory thresholds today through Sunday. However....a wave of low pressure and its associated southerly swell will be enough to generate 4 to 5 foot southerly swell later today into tonight across our southern outer-waters. Therefore...we have hoisted a small craft advisory for those waters later today into tonight but conditions should drop back below criteria for Sunday. The biggest issue for mariners will be areas of fog...some of which will be locally dense especially over our southern waters during the overnight and morning hours. Outlook /Sunday Night through Thursday/... Sunday Night through Monday: Winds less than 25 kt. Seas locally approaching 5 ft. Slight chance of rain showers. Monday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Tuesday: Winds less than 25 kt. Areas of seas approaching 5 ft. Chance of rain showers, isolated thunderstorms. Tuesday Night: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers. Wednesday through Thursday: Winds less than 25 kt. Areas of seas approaching 5 ft. && .BOX WATCHES/WARNINGS/ADVISORIES... CT...None. MA...None. RI...None. MARINE...Small Craft Advisory until 4 AM EDT Sunday for ANZ254>256. && SYNOPSIS...Frank/McMinn NEAR TERM...Frank SHORT TERM...Frank LONG TERM...McMinn AVIATION...Frank/McMinn/Mensch MARINE...Frank/McMinn
