.SYNOPSIS...
A COLD FRONT WILL CROSS THE REGION EARLY TODAY. HIGH PRESSURE BUILDS
IN TUESDAY INTO EARLY WEDNESDAY. ANOTHER COLD FRONT WILL ARRIVE IN
NORTHERN MAINE LATE WEDNESDAY.
&&

.NEAR TERM /THROUGH TODAY/...
HAVE UPDATED PROBABILITY OF PRECIPITATION AND WEATHER GRIDS TO
BETTER FIT TIMING OF ONGOING SYSTEMS.

HAVE INCLUDED ENHANCED WORDING ACROSS THE REGION THIS MORNING AS THERE
WILL BE THE POTENTIAL FOR GUSTY WINDS AND HAIL IN ANY THUNDERSTORMS.
PWATS ARE ALSO ON THE HIGH SIDE SO THERE WILL BE THE CHANCE FOR
SOME HEAVY RAINFALL AS WELL. THE COLD FRONT WILL CROSS THE REGION
DURING MONDAY. THE BEST CHANCES FOR THUNDERSTORMS WILL BE ACROSS
DOWNEAST MAINE WHERE INSTABILITY WILL BE GREATER DUE TO THE LATER
FRONTAL PASSAGE. NOTED THAT SPC HAS NOW MOVED THE SLIGHT RISK AREA
ACROSS FAR SOUTHERN MAINE AND SOUTHERN NEW ENGLAND SO HAVE NOT
INCLUDED ANY ENHANCED WORDING. IMPROVING WEATHER WILL RETURN BY
LATE MONDAY AS THE FRONT MOVES EAST AND HIGHER PRESSURE BUILDS IN
FROM THE WEST.
&&

.SHORT TERM /TONIGHT THROUGH WEDNESDAY/...
FAIR WEATHER WILL TAKE HOLD MONDAY NIGHT IN THE WAKE OF A COLD
FRONT WITH NORTHERLY WINDS USHERING IN A COOLER AND MORE
COMFORTABLE AIR MASS. HIGH PRESSURE WILL BUILD INTO THE REGION FOR
TUESDAY BRINGING PLENTY OF SUNSHINE ALONG WITH SEASONAL
TEMPERATURES AND LOW HUMIDITY LEVELS. THIS RIDGE WILL CREST OVER
THE FORECAST AREA TUESDAY NIGHT BEFORE SLIDING OFF THE EASTERN
SEABOARD THROUGH WEDNESDAY. AS A RETURN FLOW FROM THE SOUTHWEST
SETS UP THIS WILL BRING IN SOMEWHAT WARMER TEMPERATURES ALONG WITH
GRADUALLY INCREASING HUMIDITY LEVELS. THE NEXT COLD FRONT WILL
APPROACH FROM THE NORTH BY LATE WEDNESDAY BRINGING THE POTENTIAL
FOR SHOWERS AND THUNDERSTORMS MAINLY TO NORTHERN PARTS OF THE
ZONE.
&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
THE PERIOD WEDNESDAY NIGHT INTO FRIDAY WILL FEATURE SHORTWAVES
ROTATING AROUND AN UPPER LOW IN NORTHERN QUEBEC AND ALONG THE
NORTHERN EDGE OF A POWERFUL UPPER RIDGE IN THE MIDWESTERN US. THE
CONTRAST BETWEEN AIR MASSES WILL HELP FUEL
THUNDERSTORMS...POSSIBLY SEVERE WITH THESE SHORTWAVES. THE FIRST
SHORTWAVE ARRIVES WEDNESDAY NIGHT WITH THUNDERSTORMS FOR NORTHERN
MAINE. ALTHOUGH NWP IS OFFERING A WIDE VARIETY OF SOLNS FOR
THURSDAY...WILL GO WITH THE SCENARIO OF WEDNESDAY NIGHT'S FRONT
STALLING IN MAINE AND ANOTHER SHORTWAVE ARRIVING RAPIDLY WITH
ANOTHER ROUND OF THUNDERSTORMS THURSDAY AFTERNOON...MOSTLY IN
NORTHERN MAINE. UNDER THIS SCENARIO...A COLD FRONT DRAGS THROUGH
THE STATE DURING FRIDAY WITH THE THREAT OF THUNDERSTORMS MORE DOWN
EAST ON FRIDAY. THIS COLD FRONT IS EXPECTED TO USHER IN HIGH
PRESSURE AND COOLER TEMPS FOR NEXT WEEKEND.
&&

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
NEAR TERM: A COLD FRONT WILL PUSH ACROSS THE REGION MONDAY. VFR
IS EXPECTED AT THE NORTHERN TAF SITES BUT THERE MAY BE SOME
LINGERING TSTMS AND BRIEF MVFR CONDS AT KBGR/KBHB TERMINALS.

OF WEDNESDAY. THUNDERSTORMS WITH TEMPO IFR CONDITIONS WEDNESDAY
