DISCUSSION
KEY MESSAGE 1...
AN UPPER TROUGH SHIFTS EAST AWAY FROM THE AREA TONIGHT WHILE
SURFACE HIGH PRESSURE WILL BE CENTERED TO THE NORTH OF THE
FORECAST AREA. A FEW CLOUDS COULD BE POSSIBLE WITH A WEAK
DISTURBANCE, THOUGH DRIER AND COOLER CONDITIONS ARE EXPECTED
THROUGHOUT THE AREA.
WHERE WINDS CALM AND SKIES CLEAR, RADIATIONAL COOLING SHOULD
ALLOW TEMPERATURES TO DIP LOW ENOUGH FOR FROST AND FREEZE TO
DEVELOP -- PARTICULARLY IN THE SHELTERED VALLEYS AND TYPICAL
COLD SPOTS OF THE NORTHEAST MOUNTAINS AND ADJACENT FOOTHILLS.
HOWEVER, LOCATIONS WHERE CLOUDS AND LIGHT FLOW PERSIST SHOULD
REMAIN ABOVE FREEZING. A FROST ADVISORY HAS BEEN ISSUED FOR
PORTIONS OF THE NORTHEAST MOUNTAINS LATE TONIGHT INTO EARLY
TUESDAY MORNING, WHILE A FREEZE WARNING COVERS SOUTHEAST
RANDOLPH AND NORTHWEST POCAHONTAS COUNTIES.
KEY MESSAGE 2...
AFTER A QUIET TUESDAY, A COLD FRONT CROSSES THE AREA ON
WEDNESDAY AS THE PARENT LOW TRAVELS THROUGH SOUTHEASTERN
CANADA. A BAND OF PRECIPITATION IS EXPECTED TO SPROUT UP AHEAD
OF THE FRONT EARLY WEDNESDAY MORNING AND PROGRESS THROUGH THE
FORECAST AREA DURING THE DAY. THE BULK OF THIS ACTIVITY SHOULD
EXIT BY MID AFTERNOON, THEN A SECONDARY LINE COULD DEVELOP ALONG
THE FRONT LATER THAT AFTERNOON AND EVENING. ALTHOUGH A FEW
STRONGER STORMS COULD BE POSSIBLE WEDNESDAY AFTERNOON AND
EVENING, SEVERE POTENTIAL MAY BE LESSENED IF THERE IS NO BREAK
BETWEEN THE EARLIER ACTIVITY AND THE ARRIVAL OF THE FRONT.
AFTER THE FRONT DEPARTS, THE PASSAGE OF AN UPPER TROUGH MAY
SUPPORT ADDITIONAL SHOWERS AND STORMS, PRIMARILY IN AND NEAR
THE MOUNTAINS WEDNESDAY NIGHT INTO THURSDAY.
KEY MESSAGE 3...
HIGH PRESSURE TAKES HOLD FOR THE END OF THE WORK WEEK, WITH
POTENTIAL FOR SOME PATCHY FROST IN THE NORTHEAST MOUNTAINS EARLY
FRIDAY MORNING. THEREAFTER, THE PATTERN BECOMES MORE ACTIVE
AGAIN FOR THE WEEKEND AND BEGINNING OF NEXT WEEK. TEMPERATURES
ARE ALSO EXPECTED TO TREND MUCH WARMER, WITH SUMMER-LIKE HIGHS
ANTICIPATED FROM SATURDAY INTO MONDAY.
AVIATION /00Z TUESDAY THROUGH SATURDAY/
AFTERNOON CU FIELDS HAVE BEGUN TO ERODE THIS EVENING WITH THE
LOSS OF DAYTIME HEATING. SIGNAL FOR RIVER VALLEY FOG AND LOW
CEILINGS REMAINS NESTLED ALONG THE HIGHER TERRAIN OVERNIGHT, BUT
COULD FORM AS FAR NORTH AS EKN AND AS FAR WEST AS CRW BY TUESDAY
MORNING. FOG EROSION WOULD THEN TAKE SHAPE AFTER SUNRISE AND
TRANSITION TO MOSTLY CLEAR SKIES FOR THE REST OF THE DAY. WINDS
GROW CALM TONIGHT AMID NEARBY HIGH PRESSURE, THEN WILL BECOME
LIGHT OUT OF THE SOUTHWEST FOR TUESDAY.
