DISCUSSION
KEY MESSAGE 1: HEAT BUILDS THIS WEEK. HIGH CONFIDENCE IN ABOVE
NORMAL TEMPERATURES.
A STRONG UPPER RIDGE WILL BEGIN TO STRENGTHEN OVER THE SOUTHERN
UNITED STATES BY MONDAY. THIS RIDGE WILL CONTINUE TO BUILD EAST
THROUGH THE WEEK, LEADING TO MULTIPLE DAYS OF UPPER 80S TO
UPPER 90S OVER THE REGION.
THE HEAT SHOULD PEAK WEDNESDAY, BUT REMAINS QUITE HIGH THURSDAY
AS WELL, ESPECIALLY OVER THE PIEDMONT. TEMPERATURES IN THE UPPER
80S AND UPPER 90S COMBINED WITH DEW POINTS IN THE MID TO UPPER
60S WILL RESULT IN HEAT INDICES IN THE LOWER 100S FOR PARTS OF
THE PIEDMONT AS WELL AS THE ROANOKE URBAN AREA DURING THIS
PERIOD.
THROUGH WEDNESDAY, AND POSSIBLY THURSDAY, RAIN LOOKS SCARCE,
WITH A FEW TINY CELLS TRYING TO DEVELOP IN THE AFTERNOONS AND
EARLY EVENINGS. BEST CHANCE OF STORMS WILL BE ALONG THE SOUTHERN
BLUE RIDGE, BUT STRONG SUBSIDENCE UNDER THE RIDGE WILL PREVENT
ANYTHING MORE THAN SHALLOW CONVECTION. TROUGHING OVER THE
NORTHEAST BY FRIDAY WILL AMPLIFY RESULTING IN A GREATER CHANCE
FOR RAIN/STORMS FOR THE WEEKEND AS THE STRONG RIDGING MOVES
WEST OVER THE ROCKIES.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
WIDESPREAD VFR EXPECTED, ALONG WITH LIGHT/CALM WINDS THROUGH
THIS EVENING AND GENERALLY OVERNIGHT AS WELL. SOME LOW STRATUS
AND FOG MAY DEVELOP AGAIN OVERNIGHT, PARTICULARLY FOR THE
MOUNTAIN VALLEYS... MAINLY IMPACTING LWB/BCB. EXPECTING LIGHT
WINDS AND VFR AGAIN ON MONDAY AFTER ANY FOG/STRATUS DISSIPATES.
EXTENDED AVIATION OUTLOOK...
HIGH PRESSURE WILL BUILD ACROSS THE APPALACHIAN MOUNTAINS ON
MONDAY TO BRING DRIER WEATHER AND MAINLY VFR CONDITIONS
THROUGH AT LEAST WEDNESDAY, OUTSIDE OF MORNING FOG FOR THE
MOUNTAIN TERMINALS. A FEW SHOWERS AND STORMS MAY DEVELOP
THURSDAY AFTERNOON AND EVENING.
