DISCUSSION
KEY MESSAGE 1: CONVECTION CHANCES REMAIN INTO EARLY NEXT WEEK, THEN SOMEWHAT
OF A LULL MIDWEEK BEFORE ANOTHER FRONT ARRIVES LATE WEEK. SOME
STORMS INTO SUNDAY COULD BE STRONG TO SEVERE WITH HEAVY
RAINFALL.
THE LARGE SCALE PATTERN CONTINUES TO SHOW UPPER RIDGE TO OUR
SOUTHWEST AND TROUGH OVER THE NORTHEAST WITH CONVECTIVE
PERTURBATIONS MOVING FROM THE MIDWEST EAST INTO THE OHIO
VALLEY, THEN SOME UPPER FLOW/CORFIDI VECTORS TRACK THEM ACROSS
OUR AREA.
THIS AFTERNOON/EVENING, OUTFLOWS/DIFFERENTIAL HEATING WILL
INFLUENCE THUNDERSTORM DEVELOPMENT. SHEAR WILL GENERALLY BE
WEAK, BUT STRONG UPDRAFTS AND AMPLE MOISTURE WILL YIELD THE
POTENTIAL FOR WET MICROBURSTS.
NOT MUCH CHANGE IN THE FORECAST THOUGH LOOKS LESS ACTIVE SUNDAY
WITH RIDGE BUILDING A LITTLE MORE. AS THIS HAPPENS,
TEMPERATURES WILL CONTINUE TO RISE, WITH NEAR HEAT ADVISORY
CRITERIA LEVELS POSSIBLE ACROSS THE PIEDMONT OF VIRGINIA AND
NORTH CAROLINA ON SUNDAY AND MONDAY. BY MONDAY EVENING THE RIDGE
GETS FLATTENED WITH MORE SHORTWAVES MOVING ACROSS THE AREA ONCE
AGAIN. THE FLOW BEING MORE WESTERLY MAY KEEP STORM COVERAGE FOR
EAST OF THE MOUNTAINS SOMEWHAT LIMITED.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
VFR CONDITIONS ARE EXPECTED FOR A MAJORITY OF THE TAF PERIOD FOR
ALL TERMINALS. COULD SEE CONVECTION AROUND BLF/LWB/BCB THIS
AFTERNOON FROM 18-22Z, THEN POSSIBLY AT ROA/LYH/DAN IN THE
20-24Z TIME FRAME, MAINLY VCTS. SHOULD A STORM MOVE OVER
VSBYS/CIGS COULD DROP TO IFR.
OVERALL, WINDS WILL REMAIN LIGHT AT AROUND 5-10 KNOTS OUT OF
THE WEST/NORTHWEST FOR ALL TERMINALS THROUGH THE TAF PERIOD.
MVFR TO IFR RESTRICTIONS LOOK TO DEVELOP ONCE AGAIN AT ALL
TERMINALS EXCEPT DAN DURING THE OVERNIGHT AND EARLY MORNING
HOURS ON SATURDAY. THESE RESTRICTIONS WILL LIKELY LIFT SHORTLY
