.NEAR TERM /THROUGH FRIDAY/...
-- Changed Discussion --
CLEAR SKIES AND CALM WINDS WILL ALLOW ANOTHER STEEP AND SHALLOW
RADIATION INVERSION TO FORM TONIGHT WITH ONE MORE NIGHT OF
WIDESPREAD SUBZERO READINGS. THE AIR MASS IS VERY DRY AND MODELS
ARE HAVING A HARD TIME WITH THE VERY LOW DEW POINTS. HAVE GONE
BELOW MOST GUIDANCE FOR TONIGHT WITH SHARP TEMPERATURE CONTRASTS
EXPECTED BETWEEN LOW LYING VALLEYS AND HIGHER TERRAIN DUE TO THE
SHALLOW INVERSION. THE LOWEST TEMPERATURES WILL LIKELY BE AT LEAST
5 TO 10 DEGREES WARMER THAN LAST NIGHT FOR MOST LOCATIONS AS H925
TEMPERATURES WILL MODERATE SIGNIFICANTLY BY FRIDAY MORNING. THE
COLDEST VALLEYS IN NORTHERN ZONES SHOULD BOTTOM OUT IN THE 13 TO
16 BELOW RANGE. THE INVERSION WILL BE QUICKLY ELIMINATED IN THE
MORNING BY RELATIVELY WARM SW WINDS AND CONTINUED WARM AIR
ADVECTION AT ALL LEVELS. TEMPERATURES WILL REACH UP TO THE UPPER
30S DOWN EAST AND IN THE BANGOR AREA AND ABOVE FREEZING FOR MOST
LOCATIONS. MOISTURE IN THE FORM OF HIGHER DEW POINTS WILL ADVECT
NORTHWARD IN THE SW FLOW WITH READINGS OVER 20 DEGREES HIGHER THAN
TODAY. WINDS WILL ALSO PICK UP WITH GUSTS REACHING 20 TO 25 MPH IN
THE AFTERNOON.

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
-- Changed Discussion --
EARLY IN THE SHORT RANGE PERIOD FOR FRIDAY NIGHT THE AREA WILL BE
SITUATED BETWEEN AN APPROACHING COLD FRONT FROM THE NORTH AND A
LOW PASSING SOUTH OF THE AREA. TEMPERATURES WILL BE MUCH MILDER THAN RECENT
NIGHTS WITH LOWS GENERALLY IN THE UPPER TEENS AND LOW 20S EXCEPT
MID TO UPPER 20S ALONG THE COAST.

THE COLD FRONT MENTIONED ABOVE WILL BRING THE CHANCE FOR SOME SNOW
FLURRIES ACROSS THE NORTH LATE FRIDAY NIGHT THROUGH THE FIRST PART OF
SATURDAY AS IT MOVES THROUGH. OTHERWISE DRY WEATHER WILL PREVAIL
THROUGH THE WEEKEND. HIGHS SATURDAY WILL BE IN THE 30S TO AROUND
40 SOUTH WITH TEMPERATURES COOLING OFF BY 5 TO 10 DEGREES FOR
SUNDAY BEHIND THE FRONT.
-- End Changed Discussion --
&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
-- Changed Discussion --
RELATIVELY QUIET AND SEASONABLY COLD WEATHER WILL CONTINUE INTO
NEXT MONDAY AS THE NEXT DISTURBANCE PASSING THROUGH EARLY MONDAY
WILL BE WEAK AND LOOKS TO PASS MAINLY SOUTH OF THE AREA. A SECOND,
SLIGHTLY STRONGER IMPULSE AND ASSOCIATED COLD FRONT WILL BRING A BETTER
CHANCE FOR SOME FLURRIES AND SNOW SHOWERS HEADING INTO TUESDAY.
THE NEXT THREAT FOR A MORE SIGNIFICANT STORM DOESN`T ARRIVE UNTIL
MID TO LATE NEXT WEEK BUT AT THIS POINT THERE IS CONSIDERABLE
UNCERTAINTY REGARDING THE EVOLUTION OF THIS SYSTEM. TEMPERATURES WILL
REMAIN NEAR OR BELOW NORMAL THROUGH THE LONG RANGE PERIOD.
-- End Changed Discussion --
&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
-- Changed Discussion --
NEAR TERM: VFR OUTSIDE OF A SLIGHT RISK OF IFR VIS AT BHB NEAR
SUNRISE FRIDAY AS MOIST AIR MOVES NORTH FROM THE WATERS.

SHORT TERM: VFR WILL PREDOMINATE THROUGH MOST OF THE WEEKEND. THE
EXCEPTION WILL BE LATE FRIDAY NIGHT INTO THE FIRST PART OF
SATURDAY IN THE NORTH AS A COLD FRONT MOVING THROUGH COULD BRING
MVFR CIGS. A PAIR OF CLIPPER TYPE SYSTEMS COULD ALSO BRING PERIODS
OF MVFR/IFR CONDITIONS FOR BOTH MONDAY AND TUESDAY AS THESE
IMPULSES MOVE THROUGH.
-- End Changed Discussion --

.MARINE...
-- Changed Discussion --
NEAR TERM: NO SIGNIFICANT ISSUES ARE EXPECTED. WINDS WILL
DECREASE TONIGHT WITH HIGH PRESSURE BUILDING RIGHT OVER THE
WATERS...BUT SW WINDS WILL INCREASE FRIDAY AFTERNOON AS THE HIGH
MOVES EAST WITH SOME GUSTS TO 20 KTS.

SHORT TERM:
A PERIOD OF MARGINAL SCA CONDITIONS DUE TO BOTH WINDS AND SEAS
WILL BE POSSIBLE SATURDAY NIGHT INTO EARLY SUNDAY IN THE WAKE OF A
COLD FRONT WITH OTHERWISE RELATIVELY QUIET CONDITIONS EXPECTED ON
THE SEAS.
