DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
HIGH PRESSURE BUILDS BACK INTO THE REGION TODAY IN THE WAKE OF
A COLD FRONT THAT HAS USHERED IN A SLIGHTLY COOLER AIRMASS, SO
EXPECT TEMPERATURES TO ONLY MAX OUT IN THE MID TO UPPER 40S FOR
THE MOUNTAINS AND FOOTHILLS, AND IN THE LOW 50S TO THE SOUTH.
HIGH PRESSURE THEN BECOMES CENTERED DIRECTLY OVERHEAD TONIGHT
WHICH IS GOING TO LEAD TO ANOTHER NIGHT OF STRONG RADIATIONAL
COOLING. THIS PATTERN HAS BEEN SO PERSISTENT LATELY THAT THE NBM
(WHICH USUALLY DOESN'T HANDLE RADIATIONAL COOLING ALL THAT
WELL) ACTUALLY LOOKS PRETTY REASONABLE, BUT MOS HAS STILL BEEN
INCORPORATED INTO SOME OF THE BETTER RADIATING LOCATIONS TO ADD
SOME VALUE THERE. THE RESULT IS LIKELY ONE OF THE COLDER NIGHTS
WE HAVE SEEN SO FAR WITH WIDESPREAD 20S AND UPPER TEENS (LOW
TEENS AT THE BETTER RADIATORS) EXPECTED BY EARLY WEDNESDAY
MORNING.
HIGH PRESSURE THAN MOVES ITS WAY OFFSHORE WEDNESDAY WITH RETURN
FLOW STARTING A WARMING TREND THAT WILL LAST THROUGH THE END OF
THE WORK WEEK. WEDNESDAY IS LIKELY GOING TO SEE TEMPERATURES
TOP OUT IN THE 50S AND RISING DEWPOINTS MAKING FOR A WARMER
NIGHT IN THE 30S. HIGH ASTROTIDES ARE GOING TO PUSH THIS
MORNING'S AND WEDNESDAY MORNING'S HIGH TIDES CLOSE TO MINOR
FLOOD STAGE, BUT CALM CONDITIONS AND OFF SHORE WINDS ARE
EXPECTED TO RESULT IN LITTLE TO NO SURGE MEANING THEY SHOULD
STAY BELOW. BY THURSDAY TEMPERATURES SHOULD BE ABLE TO MIX IN TO
THE 70S ACROSS THE AREA. DEWPOINTS ALSO CONTINUE TO RISE, SO
THURSDAY NIGHT LOOKS TO END UP RELATIVELY MILD WITH TEMPERATURES
LIKELY ONLY BEING ABLE TO FALL INTO THE MID TO UPPER 40S.
CLOUDS AND A FEW SHOWERS ARE POSSIBLE THURSDAY NIGHT AHEAD OF
THE NEXT FRONTAL PASSAGE AND WHILE GLOBAL MODELS HAVE BEEN
CONSISTENTLY SHOWING A SIGNAL FOR MORE WIDESPREAD SHOWER
CHANCES, AS THIS EVENT MOVES INTO THE HI- RES WINDOW THE
SUGGESTION IS FOR MORE WIDELY SCATTERED SHOWERS. SO, WHILE THIS
DOES TECHNICALLY MEAN MANY LOCATIONS WILL SEE A HIGHER CHANCE
FOR RAIN THEN THEY HAVE SEEN OVER THE LAST WEEK OR SO, THAT
CHANCE IS STILL GOING TO BE QUITE LOW. IN FACT THE LATEST NBM,
STILL DOESN'T EVEN REALLY WANT TO BRING POPS SOUTH OF THE
MOUNTAINS, BUT AGAIN AS MORE HI- RES MODEL DATA GETS INGESTED
LOW CHANCES WILL LIKELY BEGIN EXPANDING SOUTHWARD.
THE FRONT LIKELY BEGINS CROSSING EARLY FRIDAY MORNING WITH THE
COLDER AIR FILLING IN NORTH OF THE MOUNTAINS BY THE AFTERNOON
AND LIMITING THE TEMPERATURES IN THOSE LOCATIONS TO THE MID TO
UPPER 50S. SOUTH OF THE MOUNTAINS SHOULD BE ABLE TO SEE
TEMPERATURES WARM INTO THE MID TO UPPER 60S (MAYBE EVEN 70 ON
THE COASTAL PLAIN) BEFORE THE FRONT CROSSES. HIGH PRESSURE THEN
MOVES BACK OVERHEAD FOR HALLOWEEKEND WHICH LOOKS DECENT AS THIS
FRONTAL PASSAGE DOESN'T QUITE PACK THE PUNCH OF THE CURRENT ONE,
SO DAYTIME TEMPERATURES LOOK TO END UP IN THE UPPER 50S AND LOW
60S. FOR SATURDAY NIGHT TEMPERATURES LOOK TO GENERALLY BE IN
THE 40S AND 50S DURING TRICK OR TREAT TIME. FOR WHAT IT'S WORTH
GLOBAL MODELS HAVE BEEN SHOWING A PRETTY CONSISTENT SIGNAL FOR
NOVEMBER TO BEGIN WET, SO THAT WILL BE THE WINDOW TO WATCH FOR
OUR NEXT CHANCE OF POTENTIALLY APPRECIABLE RAINFALL.
AVIATION /12Z TUESDAY THROUGH SATURDAY/
THROUGH 12Z WEDNESDAY: VFR CONDITIONS ANTICIPATED WITH A NW
BREEZE CONTINUING THROUGH THE MORNING. SOME GUSTS ARRIVE IN THE
AFTERNOON, BUT WINDS BECOME CALM FOR TONIGHT. CAN'T RULE OUT
SOME VALLEY FOG AT LEB LATE TONIGHT, BUT DRY AIR SHOULD LIMIT
THIS TO JUST BEFORE DAWN.
OUTLOOK...
WEDNESDAY-THURSDAY...VFR CONDITIONS EXPECTED. THERE MAY BE
BRIEF PERIOD OF IFR OR LOWER IN VALLEY FOG AT LEB, CON, AND MHT
PRIOR TO SUNRISE.
FRIDAY: ANOTHER FRONT APPROACHES THE REGION AND SOME MVFR CIGS
MAY BE POSSIBLE NORTH OF THE MTNS, INCLUDING HIE.
SATURDAY: VFR CONDITIONS EXPECTED.
MARINE
A BRIEF PERIOD OF SCA WIND GUSTS IS EXPECTED INTO EARLY THIS
MORNING BEFORE WINDS DIMINISH UNDER ANOTHER APPROACHING HIGH
PRESSURE. AS THAT HIGH DEPARTS THE REGION LATE IN THE WEEK,
SOUTHWEST WINDS WILL INCREASE. THEY WILL AT LEAST APPROACH SCA
GUSTS AND ALLOW SEAS TO BUILD IN THE VICINITY OF THE COASTAL
WATERS NORTH OF PORT CLYDE, BUT OVERALL I EXPECT CONDITIONS TO
REMAIN BELOW SCA THRESHOLDS.
GYX WATCHES/WARNINGS/ADVISORIES
ME...NONE.
NH...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 10 AM EDT THIS MORNING FOR ANZ150-
152-154.
