.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
-- Changed Discussion --
COLD FRONT IS COMING THROUGH ON TWO SFC BOUNDARIES...THE FIRST OF
WHICH HAS JUST RECENTLY CLEARED PORTLAND...WITH TDS DROPPING
QUICKLY BEHIND IT. THE SECOND BOUNDARY IS CROSSING VT ATTM...WHICH
SHOWS A SLIGHT VEERING OF THE SFC WINDS...AND ALSO BRINGS ANOTHER
ROUND OF TD FALLS. BEHIND THIS SECOND BOUNDARY COULD SEE AN HOUR
OR SO OF WIND GUSTS AROUND 25 MPH....AND PERHAPS A FEW SHRA IN THE
MTNS. OTHERWISE SHRA IN ERN ZONES LOOK TO COME TO AN END BETWEEN
20Z AND 21Z. CAA WILL CONTINUE THRU TONIGHT...AS WE SHOULD W FLOW
THRU THE NIGHT...MAYBE AROUND 10 MPH OR SO CWA WIDE. THIS WILL
PRECLUDE ANY FROST DEVELOPMENT TONIGHT.

.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
-- Changed Discussion --
SFC HIGH BUILDING TO THE WEST...AND LOW PRESS TO OUT NE WILL
COMBINE TO BRING A SOMEWHAT BREEZY AND CHILLY DAY. WEST WINDS LOOK
TO SUSTAIN AT 10 TO 20 MPH...WITH GUSTS OF 25-30 MPH. DOWNSLOPE
SHOULD KEEP THE COASTAL PLAIN M/SUNNY...BUT UPSLOPE CLOUDS WILL
DEVELOP IN THE MTNS...ALTHOUGH LOW LVLS LOOK TOO DRY TO MENTION
SHRA. HIGH WILL BE LIMITED TO THE 50S...MAYBE REACHING THE 60 IN
SRN NH AND SW ME.

FOR MONDAY NIGHT THE SFC HIGH BEGINS TO BUILD IN OVER THE
CWA...AND WINDS WILL DIMINISH SOMEWHAT...ALLOWING TEMPS TO DROP
INTO 30S...WITH UPPER 20S IN THE COLDER SPOTS IN THE MTNS. WILL
LIKELY SEE FROST INLAND...BUT IN THE COASTAL ZONES...WHERE THE
GROWING SEASON HAS BEGUN...IT REMAINS QUESTIONABLE GIVEN LINGERING
LIGHT FLOW...AND FORECAST MINS MAINLY IN THE UPPER 30S. STILL...IT
REMAINS POSSIBLE AND THOSE WITH TENDER PLANTS IN THE GROUND SHOULD
MONITOR THE FORECAST.

IN MTN CLDS. TEMPERATURES TUESDAY WILL BE BELOW NORMAL BUT REBOUND

IN FAIR AGREEMENT ON THIS. THE FRONT WILL LIKELY STALL TO OUR
SOUTH. ANOTHER WEAK COLD FRONT MAY MOE THROUGH LATE FRI AS
