706am EDT Thu Mar 30 2023

A strong cold front will cross the area early this morning. High pressure will build south of the region on Friday. Low pressure will approach Friday night and track to our north Saturday into Saturday night. A cold front will cross the area late Saturday night followed by High pressure Sunday into Monday.

Near Term - Through Tonight
705 am Snow showers are heavier in southern areas vs northern areas and have had to do some edits to Probability of Precipitation grids. Still expecting patchy blowing snow over northern agricultural areas this morning into the afternoon. Issued special weather statement for locally reduce visibilities in heavy snow showers from Mars Hill and south twd the coast. By the time SPS expires the line should be into Canada.

Prev discussion blo... Mesoanalysis indicates lopressure weakening to the north of the St. Lawrence with convective line of mainly snow showers just entering into warning portions of FA. Webcams in the Greenville area showing a fairly heavy snowburst causing vsby reductions down to at least a half-mile and a quick inch of snow on the ground. Expect this to continue as the line slides east with vsby reductions mainly expected because of quick bursts of snow. Greatest omega values are co-located with snow growth area along the arctic front owing to the extremely hvy snowfall rates.

Cold air and strongest winds are lagging behind the front by about 75 miles. Thus, not expecting much in the way of a true snow squall with winds lagging behind quite a distance. Will continue to hit heavy snowfall rates across central and northern areas this morning, especially as we get closer to the morning rush. Further south, light rain is being reported in the Waterville and Augusta areas with Bangor possibly rain at onset before quickly going over to snow with evaporational cooling taking place under fairly intense lift. Not to mention the impact of rain on area roadways before freezing as caa gets draw in from the northwest, especially on bridges. All in all a fairly hazardous commute this morning across all areas.

Front and heavy snow showers will move into NB by 12z. Cold air will quickly filter in behind with winds picking up out of the west. Strong wind gusts up to 30 mph will result in blowing snow today over open agricultural areas. High temperatures will range from 15 to 20 degrees below yesterdays highs. A brisk and raw day is on tap with wind chill temps down into the lower teens across most of the area with single digit wind chills across the northwest.

Cannot rule out snow showers across the north in wrap-around snow showers in the wake of the front. Compact upper low will be crossing the Crown this evening and have allowed snow showers to linger through the day into the early part of the evening.

For tonight high pressure will slowly nose toward the region but winds stay well mixed as pressure gradient remains tight. Although skies over all areas radn/l cooling will be hard to come and hv kept mins in the lower teens to the north of Katahdin with nr 20 over Downeast. If hipressure is able to build in quicker than its not out of the realm of possibility that temps will be able to drop toward zero over the deeper valleys acrs the northwest.

Short Term - Friday Through Saturday
High pressure well south of the area, with a surface ridge extending north across our region, will bring a mostly sunny and tranquil morning Friday morning. Clouds will increase Friday afternoon well ahead of a large area of low pressure in the Plains. As precipitation pushes into our region late Friday into Friday evening, temperatures will be cold enough for snow across much of the area. Light and spotty snow will continue across the north late Friday night with snow changing to rain over southern areas. The low center will track from southern Ontario into southern Quebec Saturday morning pulling warmer air and moisture northward across the area changing precipitation over to rain across the rest of the region. One of the remaining forecast challenges is how much of a secondary low will form along the Maine coast Saturday morning. A stronger secondary would hold cold air in over the north allowing a couple inches of snow to fall before the change-over while a weaker secondary would allow warmer air to surge in faster changing precipitation over to rain more quickly and limiting any accumulation. This storm system looks like a fast mover with a dry surge lifting northeast into our area by late Saturday afternoon. About a half inch of rain is possible over the area, mostly across the north, Saturday before the dry intrusion makes it in. Rain will taper off to spotty showers as the dry surge moves in late Saturday afternoon but low clouds will likely remain over the region.

Long Term - Saturday Night Through Wednesday
Low pressure will track north of the area Saturday evening pulling a strong cold front across our region. A concentrated line of rain showers may accompany the cold front late Saturday night. The GFS (Global Forecast System) has a small trailing low across our area with the frontal passage while the ECMWF (European Centre for Medium-Range Weather Forecasts) just has an open cold front. Strong gusty cold northwesterly winds will follow on Sunday with a mostly sunny sky. Highs will be below freezing over the northern half of the region and in the upper 30s Downeast. High pressure will drop south of the area Sunday night allowing the wind to diminish and shift to westerly. Clouds will increase overnight Sunday night into Monday ahead of a new low tracking through southern Canada. This looks like a weak and fast moving low which will be moving too quickly to pick up appreciable amounts of moisture, but could give a bit of light snow over the north and rain showers Downeast later Monday as it tracks into western Quebec. This low will dissipate and wash out to the east in the rapid westerlies on Tuesday as high pressure over central Canada builds into our region. This will bring dry and seasonable weather Tuesday into Tuesday night. The next chance for showers will come with another low tracking well to our northwest later Wednesday into Wednesday night.

Near Term: Winds increase to gale force early this morning over the outer waters and above SCA (Small Craft Advisory) levels on the intracoastal waterway. Once winds diminish over the outer waters this evening it will likely have to be converted to an SCA (Small Craft Advisory) through the end of the period. Seas ramp up above 5ft over the outer waters this morning and remain elevated into early Friday morning.

Short Term: Winds will drop below SCA (Small Craft Advisory) Friday, then increase to SCA (Small Craft Advisory) Friday night and gale on Saturday in strong S winds. The winds may drop back to SCA (Small Craft Advisory) Saturday night then increase to strong SCA (Small Craft Advisory) or gale on Sunday in gusty NW winds following a cold front. Winds should drop to SCA (Small Craft Advisory) Monday then below SCA (Small Craft Advisory) Tuesday in high pressure. The highest seas will be from late Saturday through Saturday night and into Sunday with seas up to 10 ft in response to the southerly gale on Saturday.
