Synopsis for massachusetts and rhode island coastal waters.. Northeast winds will be gradually shifting to the east by midweek. A tropical depression may form off the coast of florida early next week. This system may track close enough to affect the coastal waters with elevated seas by mid week. A cold front will approach the waters from the west on Thursday. For information on possible hazardous weather beyond the 24-36 hour forecast period, please visit www.weather.gov/boston and follow the current hazards link above the map on the left.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbox 260550 afdbox area forecast discussion national weather service boston norton ma 150 am edt Mon aug 26 2019 Synopsis Patchy low clouds over ri and SE mass will diminish this morning. High pressure over the maritimes will build over southern new england today and maintain dry pleasant weather through Tuesday. Possible showers Wednesday and Thursday ahead of a cold front. Still keeping an eye on the track of a potential tropical system offshore late this week, which could produce high surf and dangerous rip currents along the immediate shoreline. Near term until 6 am this morning Satellite imagery... Nighttime microphysics and shortwave ir... Shows low clouds moving slowly southwest across SE mass and ri. These will continue to move across this area overnight, spreading for a time into northeast ct as well. A few sprinkles drizzle possibly in this area, but mainly dry conditions. A few changes were made to sky cover forecast to expand this area through 2 am. Clear and dry conditions across the remainder of southern new england overnight. Observed temperatures at 9 pm were in the mid 50s to mid 60s. Expect further cooling overnight, with overnight mins in the mid 40s through the 50s. This is in line with the existing forecast, so no changes planned to the forecast. Short term 6 am this morning through 6 pm Tuesday 2 pm update... Monday... looking to clear out. A continued long fetch off across the gulf of me, two things: 1.) sea-surface temperatures have lowered a bit with the turbidity and upwelling of the waters, and 2.) dry air advection will be quite strong and deeper within the column compared to today and sinking. So an expectation that low clouds will linger across new england during the morning hours, gradually dissipating S W with drier, subsiding pushing s. But not ruling out scattered to broken cloud decks given boundary layer mixing of onshore cool, moist air. Expect cloudy issues to linger especially s-coastal new england but lesser drizzle issues. Late summer Sun still strong while mixing out to h85 undergoing cold air advection, around +8c, another day of 70s throughout the interior while 60s along the E se shore. Monday night... becoming clear. Daytime heating concludes, dry air and high pressure in place, looking at the boundary layer to decouple and light winds to prevail over most of S new england albeit the southeast. Warm air advection aloft, moisture is trapped beneath the dry inversion just above the surface. Dense fog not out of the question especially in areas of onshore flow and or higher dewpoints (notably earlier in the day with the cross-over threshold). Lean with cooler guidance and evaluate fog based on winds (below 3 mph) along with temperature- dewpoint thresholds of 2 degrees or less. This as a first guess, fog seemingly will be more prevalent. Long term Tuesday night through Sunday Highlights... * temperatures will remain below normal Tuesday, then will moderate to near and above normal by late this week * scattered showers will move across our region sometime late Wednesday into Thursday ahead of a cold front. Details... Tuesday... high pressure will remain across the region, or at least close by. Dry weather and below normal temperatures expected to continue. Onshore winds will keep the immediate coastal areas even cooler. Wednesday through Friday... the biggest question remaining to be answered will be how close a potential tropical system comes to southern new england during this time. Latest model guidance has trended ever so slightly west, but still well within the margin of error for a forecast this far out. Still expecting a cold front to slowly approach from the west late Wednesday into Thursday. At this point, expecting scattered showers with the cold front. Instability is too poor to warrant a mention of thunderstorms in the forecast. Rainfall chances would be significantly higher if the ocean low pressure comes even closer to our region. Time will tell. The most likely impact from this coastal system would be a period of rough surf along ocean-exposed beaches. There may be another front that might approach late this week, but timing is very much in question. Near to above normal temperatures should prevail during this period. Saturday and Sunday... high pressure should be in control. Current forecast is for dry weather. Above normal temperatures Saturday, with below normal temperatures Sunday as this high pressure moves in. Aviation 06z Monday through Friday Forecaster confidence levels... low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. |
Short term through Tuesday ... High confidence. Rest of tonight... MVFR ceilings over ri and SE mass as an area of clouds drifts southwest across that area. Expect these clouds to diminish overnight. Patchy ifr fg possible where skc prevails in the ct river valley of ma as well as a few regular fog spots.VFR clear across the remainder of southern new england. Today... any remaining MVFR ceilings over ri should dissipate this morning. Similarly, any patchy fog from overnight should dissipate after sunrise. High pressure over new brunswick will maintain east-northeast winds today with strongest winds gusting 20 to 25 kt across the south coast and islands. The high will build south over our area late today, diminishing the wind. Tonight... high pressure over the region will bring clear skies and light wind. Radiational cooling will bring areas of fog, especially over the ct river valley in mass. And in the regular fog spots of SRN new england. Ifr CIGS vsbys in any fog. Tuesday... high pressure continues to bring mostly clear skies and light wind. Thin cirrus will move in from the west, most likely over ct and western ma. Kbos terminal... expect few025 through mid morning as fragments move up from the marine clouds across SE massachusetts. OtherwiseVFR clear with a continued east-northeast wind up to 10 kt. Kbdl terminal... lingering 2500 ft bases should remain south east of kbdl this morning before dissipating.VFR clear with a light ene wind. Outlook Tuesday night through Friday ...

High - greater than 60 percent. Short term through Tuesday ... High confidence. E NE winds persist through Tuesday morning. That will contribute to an E swell and wave heights around 4 to 6 feet. Strong gusts will taper slightly overnight, and then pick back up Monday with gusts up to 25 kts. As high pressure builds from the n into midweek, will see both winds and seas begin to subside. Small craft advisory headlines continue for a majority of the waters. Outlook Tuesday night through Friday ... Moderate confidence. Tuesday: winds less than 25 kt. Seas up to 5 ft.
