324am EDT Monday September 28 2020
High pressure will remain to our east today. Low pressure will develop along the Mid-Atlantic coast on Tuesday and track north across the area Wednesday. Another low from the Mid-Atlantic coast will cross the region on Thursday. The upper trough will remain over the area Friday.
Near Term - Through Tonight
A continued moist low level southerly flow will persist across the region through tonight around surface high pressure centered well to the east of Nova Scotia. Meanwhile, a deep layered southwest flow will persist aloft as a high amplitude trough continues to carve out across the nations mid section. Expect mainly cloudy skies today. A short wave embedded in the southwest flow aloft will result in scattered showers this afternoon, mainly across Downeast areas. Have maintained mention of an isolated thunderstorm for portions of Downeast, as there is some elevated instabilty, but not a lot of confidence in this. Once again high temperatures will be warmest across the North and cooler Downeast with the continued on shore flow. Expect mainly cloudy skies regionwide tonight with scattered showers early, mainly Downeast, along with some patchy fog. It will be another mild night with lows in the lower 60s.
Short Term - Tuesday Through Wednesday
The state will be well into the warm sector on Tuesday morning with patchy fog expected in a soupy airmass, especially along the coast. Dwpts will rmn in the 60s throughout the day and into the overnight hrs. Onshore flow will keep Downeast in low clouds and fog with maxes in the m/u 60s along the coast and m70s over inland areas.
SW flow aloft will be streaming deep moisture into the region. PW values around 1.0 inches on Tuesday expected to increase to between 1.5-1.75 inches by Wednesday morning. Large-scale H5 low will be located near James Bay by 00z Wednesday with compact upper low over the southeast. Energy associated with this eventual SE upper low is currently sliding thru eastern Manitoba and will continue to drop south thru the midwest on Tuesday. All med range guidance, including the ensembles, indicate an anomalously strong H5 low over the Deep South by 00z Wed.
Expect boundary to set up just to the west of the state on Tuesday and as s/wvs rotate into the northeast rain chances will slowly increase from west to east on Tuesday night. A wave of low pressure will likely develop along the front by Wednesday morning with the entire CWA likely to see a soaking rain. Have tried to indicate a break in steady rain in very hard-to-time spokes of energy but appears that Wednesday evening stands the best chance of seeing precipitation lighten up. Another wv looks to dvlp late Wednesday night in assoc with ejection of compact southeast upper low toward the end of the period in vicinity of southern New England with probability of precipitation increasing to categorical once again by 12z Thu.
Long Term - Wednesday Night Through Sunday
Surface low likely to be a fairly quick mover and slingshot into NB by 00z Friday. Longwave trough will still be located back to our west on Friday with southerly flow continuing along with chances for spotty showers. Rmndr of the long term will feature hard to time wvs as trough.iness continues with Sat night and Sunday likely to be shower-free as high pressure builds southwest out of Canada. Temps will end up being closer to climo, if not a little lower, by the end of the weekend.
Near Term: No headlines on the waters through tonight. Will continue to undercut model wave guidance, as it continues to run a few feet higher than observed. Patchy fog is expected through tonight with visibility 1 to 3 NM through tonight.
Short Term: Winds gusting to 25-30kts over offshore waters late Tuesday night and over all waters on Wed. Seas build to 8 ft on Wed, remaining over 5 ft through the end of the week.
Gusty south to southwest winds and humid conditions will continue today and Tuesday. Scattered showers are expected today with isolated showers on Tuesday. Despite warm temperatures in the low to mid 70s and south wind gusts of up to around 25 mph, the overall fire weather threat will be dampened by cloud cover, humid conditions, and showers. A wetting rain is likely Tuesday night through Thursday with most areas expected to receive between 1 and 3 inches of rainfall.
