&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
Mostly clear skies are present over most of the area early this morning. Fog and low clouds have developed over Downeast with some areas experiencing locally dense fog. Have issued an SPS for locally dense fog as it does not appear to be widespread enuf for a Dense Fog Advisory. Secondary cold front located over srn Quebec into srn Ontario with showers occurring along it, in combination with H5 cold pool. Expect showers to move into nrn areas after 14z with total rainfall averaging around 0.10 inches north of I95. Clouds will increase under 500mb trof/cold pool and temps will rise into the u60s/around 70F across the north and m70s for Downeast. Briefly considered a cold water safety SPS for this afternoon but between anticipated showers and cloud cover opted not to. This will likely be needed this weekend. Under clear skies and cold advection behind reinforcing shot of cooler an drier air, temps look to drop into the 40s for tonight.

&& .SHORT TERM /SATURDAY THROUGH SUNDAY/...
-- Changed Discussion --
A weak ridge of high pressure and a corridor of dry air will be over the region on Saturday. This will bring a mostly sunny day with only a few cumulus dotting the sky across northern parts of the region. The air will be a bit cooler and drier than recent days. However, highs from the upper 60s over the north to the low to mid 70s across interior Downeast will be a few degrees above normal for late May. Saturday night will begin mainly clear. A very weak wave in the upper level westerlies will move in overnight bringing patchy cloudiness for a partly cloudy night with the waning gibbous moon rising late in the evening. High pressure will begin to slide off to the east on Sunday. Some patchy clouds will still be around from the upper disturbance. This will bring a partly sunny day with a light southeasterly breeze carrying in some return of humidity.

&& .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
-- Changed Discussion --
High pressure will continue moving away to the east Sunday night into Monday as the gradient continues to increase between departing high pressure and a large low pressure system approaching from the Great Lakes. This will bring increasing clouds and an increasing southeasterly wind, especially during the day on Monday. The relatively cooler air pushing up from the ocean to the south, in addition to the cloudiness, will result in inland high in the upper 60s over the area. Our focus later Monday into Monday night will be on a large storm system lifting northeast from the Great Lakes region. The low will pull an occlusion into the area late Monday or Monday evening. The GFS is faster bringing rain in late Monday while the ECMWF holds the rain off until later Monday evening. A windswept rain and moderate southeasterly wind are then expected overnight Monday night, tapering off to showers and lingering drizzle during the day on Tuesday. This will result in a cool day on Tuesday with highs in the low to mid 60s. This is a large storm system and models seem to be consistent in carrying significant moderate amounts of rain so will likely go categorical on pops late Monday night even though there remains some timing differences in the long range models on when the occlusion comes through. An upper level trough and trailing surface low will lift across the area Tuesday night through Wednesday and Thursday. This will keep our weather unsettled through mid-week next week with clouds and showers around both days. High pressure and upper ridging should then bring a return of sunnier and warmer conditions on Friday.
