NEAR TERM /UNTIL 6 AM MONDAY MORNING/

7:05pm Update... No notable changes with this update as the forecast remains on track. Clear skies prevail, with temps steadily cooling off through the evening. Lows dip into the 40s and 50s again tonight, but don't look to be quite as cool as last night.

Previous...

A mid level ridge is anchored over the Northeast this afternoon with a surface high pressure system centered over the Gulf of Maine.
These features will not move much tonight through Monday night.
Mostly clear skies and light winds will allow for efficient radiational cooling tonight, which will bring lows down to the low 50s to upper 40s. Patchy fog is possible across much of the area with valley fog likely. Valley fog could be locally dense along the CT River Valley.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/
Monday will be a few degrees warmer than today as temperatures aloft increase. Fog will dissipate within a hour or two of sunrise, while along the CT Valley fog may persist until 9 AM. Skies will be mostly sunny for the rest of the day with highs will into the 80s across the interior while an afternoon sea breeze keeps the immediate coast in the 70s.

Low pressure moving through the Carolinas towards the Mid Atlantic will spread some high clouds into the region late Monday night.
Still, conditions look favorable for some radiational cooling with lows dropping into the 50s and the formation of valley fog.

LONG TERM /TUESDAY THROUGH SUNDAY/
Overview: Rex blocking slowly breaks down to end the week. Temps will trend cooler...and while widespread precip remains unlikely there will be some chances for showers towards the middle of the work week.

Impacts: No weather impacts anticipated in the extended...but there is a chance for some measurable rain towards the middle of the week which will be a welcomed sight.

Forecast Details: As usual the breakdown of the block will be slow going. The remnants of a subtropical disturbance off the Southeast coast will drift inland and north along the East Coast. That will provide our only real chance at organized precip over the next week or so. How far north the deeper moisture and showers will make it depends on a S/WV trof forecast to drop thru the St. Lawrence River Valley. The timing may force the disturbance south of the forecast area and ultimately leave much of the area high and dry yet again. Right now ensemble probabilities of measurable rainfall are quite low...no better than climatology. I have trimmed the NBM PoP and also narrowed the window a bit...especially on the front end. Otherwise the increasing deep moisture will support diurnal isolated to widely scattered showers to end the week and into the weekend.

Temps will generally slowly fall thru the week. It will start well above normal...with temps in the 80s. Increasing cloud cover will limit diurnal ranges more towards the middle and end of the week...but readings should remain in the 70s. By the latter half of the week high pressure building back in from the north should allow for some seasonably cooler overnight readings along with a return of valley fog.

AVIATION /23Z SUNDAY THROUGH FRIDAY/
Short Term...Valley fog will likely bring LIFR to KLEB and KHIE tonight with restrictions possible at KCON as fog is forecast to develop there as well. Remaining TAF sites likely remain VFR overnight. Fog dissipates between 12 and 14Z Monday morning with prevailing VFR through the day. Another night of restrictions in fog is likely at KLEB and KHIE Monday night.

Long Term...Largely VFR conditions expected to prevail during the day thru Fri. Early in the period local LIFR expected in valley fog...especially at LEB and HIE. By the middle of the week onshore flow may allow for some marine stratus and IFR is possible at all terminals.

MARINE
Short Term...High pressure over the Gulf of Maine will continue quiet conditions over the waters tonight through Monday night.

Long Term...Winds and seas expected to remain below SCA thresholds until the very end of the week. A disturbance continues north...the northeast flow along the coast will be breezy and persistent. This will lead to some gusts near 25 kt...and seas building to near 5 ft outside of the bays by Fri or Sat.
