Fxus61 kbox 221519 afdbox area forecast discussion national weather service boston norton ma 1119 am edt Thu aug 22 2019 Synopsis Another very warm and humid day as a cold front approaches from from northern portions of ny and new england today. A few showers and thunderstorms are possible this afternoon and evening as the cold front approaches, but the storms will not be as intense or widespread as yesterday Wednesday. Showers and thunder may linger through the night as a wave of low pressure moves along the front. High pressure then moves across canada into the maritimes, with steady onshore winds bringing cool temperatures this weekend into early next week. There may also be a chance for a few showers Sunday through Tuesday. Near term until 8 pm this evening 11 am update... low clouds and fog from earlier this morning has burned off and lifting into a higher deck of scattered clouds. Cold front across northern portions of ny vt nh will move south today but prefrontal winds will be west-southwest. This will begin to dry out the boundary layer which will lower dew pts and lower capes. So trending less humid this afternoon with highest capes up to 1500 j kg focusing across ri and southeast ma. This will limit potential for any strong storms to this area. In addition as winds veer to the west to southwest winds this will limit low level convergence. So in a nutshell not expecting convection to be as widespread or severe as yesterday. Otherwise, warm and humid today although as mentioned above dew pts will slowly fall from the 70s into the 60s this afternoon especially northwest of i-95 in ri and eastern ma. Short term 8 pm this evening through 6 pm Friday Tonight... the right entrance region of the upper jet will be overhead and the sfc cold front aligned with the flow ahead of the trough axis. Expect the front to stall for a short time tonight, and a low pressure wave may develop along the front. The wave would pass south of our area, but maintain a chance of showers scattered tstms during the night. Best chance would be in ct-ri-se mass. Pw remains high through the night and the moisture column remains deep. Look for continued chance of local downpours during this time. We will be north west of the cold front during the night, so expect signs of an airmass change with dew points 55 northwest to 65 southeast. Expect min temps in the upper 50s and 60s. Friday... upper trough sweeps down from canada. This brings small cold advection aloft, as well as drier air at all levels. Main question for Friday is... Will it shower or stay dry. The gfs dries out the airmass and precludes any precipitation. The ecmwf shows showers moving up from the southwest, likely in response to the upper trough and jet entrance region. For now we will show a few showers lingering along the south coast early, then moving out to sea. Otherwise dry weather. Drying of the surface air will continue with dew points falling into the 50s to around 60. Mixing reaches above 850 mb with temperatures supporting MAX sfc temps in the mid 70s to around 80. Long term Friday night through Wednesday Highlights... * expect mild temperatures and dry conditions Saturday * cooler than normal temperatures expected Saturday night through Monday, with spotty light rain or showers at times * temperatures moderate by mid week, with another chance for showers Tuesday night and Wednesday details... Friday night and Saturday... expect dry conditions as large high pressure slowly builds e across ontario and quebec. Expect a general northerly wind Friday night and early Saturday which will gradually shift to ne during the day. After mostly sunny skies across the region into Saturday afternoon, will begin to see some clouds develop later in the day. Some spotty light rain may develop across NE mass around 21z or so. Temps will top off in the 70s, mildest across interior E mass into ri as well as the lower ct valley. Saturday night through Monday... 00z model suite has come into somewhat better agreement, though some timing and track differences with the development of spotty light rain and or showers. As the large high anchors across northern new england into eastern canada, winds become a steady e-ne during most of this timeframe. Noting an increasing pres gradient on the southern extent of the high, which could mean gusty winds across coastal areas during the daytime hours Sunday and Monday. Gusts may reach up to around 25 mph there. This will bring in cool temperatures both Sunday and Monday with highs in the lower-mid 70s, though it may not even break 70 along the E coast. With the onshore flow, will see a steady fetch of low level moisture working westward. This could bring patchy light rain and or showers, with the best chances across the coastal plain. Have carried chance pops through late Monday, but can't rule out isolated showers further inland with the easterly flow. Tuesday and Wednesday... quite a bit of model solution spread amongst the 00z members. Have used a non-canadian blend for this portion of the forecast.

Temperatures moderate during this timeframe as the high begins to shift E as winds shift to s-sw. However, another front will approach later Tuesday night and Wednesday, bringing a chance for showers. Aviation 15z Thursday through Monday Forecaster confidence levels... low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Short term through Friday ... Moderate confidence. 15z update ... ifr lifr along south coast of ri into buzzards bay will slowly erode this afternoon. OtherwiseVFR with isolated MVFR in shower t-storm this afternoon with a focus across ri and southeast ma. Most storms if not all storms should remain subsevere. Previous discussion below. ========================================================================== today... Areas of MVFR lifr through around 14z, possibly a bit longer across S coastal terminals. OtherwiseVFR. Scattered showers thunderstorms possible by the afternoon. Local downpours may reduce vsbys to ifr and ceilings to MVFR as any shower tstms go past. Strong thunderstorm winds are possible, especially across ct-ri-eastern ma. Tonight... vfr with brief MVFR ifr possible in scattered showers tstms. Friday... vfr. Scattered showers along the south coast in the morning. Kbos terminal... Moderate confidence in TAF due to timing location of afternoon evening showers thunderstorms. Kbdl terminal... Moderate confidence in TAF due to timing location of afternoon evening showers thunderstorms. Outlook Friday night through Monday ... Moderate confidence Friday night through Saturday:VFR. Saturday night: ifr. Breezy. Sunday: mainlyVFR, with local ifr possible. Breezy. Slight chance ra. Sunday night: mainlyVFR, with local ifr possible. Breezy. Monday: breezy. Marine Forecaster confidence levels... low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent. Short term through Friday ... High confidence. Today and tonight... winds have diminished below 25 kt, but seas on the southern outer waters remain at 5 feet. We will end the SCA on ri and block island sound, but maintain the headline through the day on the southern and southeast outer waters. Vsbys may also be reduced at times in fog this morning. A few showers and scattered thunderstorms are possible moving off the land during the afternoon and evening. These storms could produce strong wind gusts and create poor visibility in downpours. Friday... winds gust to 20 kt with seas less than 5 feet. Leftover showers thunder in the morning on the southern waters, but these should move out to sea. Outlook Friday night through Monday ... Moderate confidence. Friday night: winds less than 25 kt. Seas locally approaching 5 ft. Saturday: winds less than 25 kt. Saturday night: winds less than 25 kt. Seas locally approaching 5 ft. Visibility 1 nm or less. Sunday: low risk for small craft advisory winds with gusts up to 25 kt. Areas of seas approaching 5 ft. Slight chance of rain. Local visibility 1 nm or less.
