WHAT HAS CHANGED
00Z AVIATION DISCUSSION...
18Z AVIATION FORECAST DISCUSSION.
ADDITIONAL THUNDERSTORM DEVELOPMENT IS POSSIBLE LATER THIS
AFTERNOON AND EVENING, BUT NEW SEVERE POTENTIAL IS
QUESTIONABLE, AND WILL DEPEND ON THE AMOUNT OF DESTABILIZATION
THAT OCCURS LATER TODAY. THIS IS DISCUSSED IN KEY MESSAGE 1.
KEY MESSAGES
1) THIS MORNING'S CONVECTION HAS LARGELY STABILIZED MUCH OF THE
ATMOSPHERE. BREAKS IN THE CLOUDS LATER TODAY MAY ALLOW FOR NEW
DEVELOPMENT DURING THE LATE AFTERNOON AND EVENING, BUT SEVERE
POTENTIAL IS QUESTIONABLE.
2) A BREAK FROM THE HEAT AND HUMIDITY IS EXPECTED THROUGH THE MIDDLE
OF NEXT WEEK IN THE WAKE OF A COLD FRONT.
DISCUSSION
KEY MESSAGE 1...
A COLD FRONT IS PUSHING SOUTHWARD ACROSS THE FORECAST AREA TODAY
WITH SHOWERS AND A FEW STRONG THUNDERSTORMS AHEAD OF IT. MUCH OF
THIS THUNDERSTORM ACTIVITY HAS ALREADY EXITED NORTHERN AND CENTRAL
WEST VIRGINIA, SOUTHEAST OHIO, AND NORTHEAST KENTUCKY, BUT A LINE OF
STRONG TO SEVERE THUNDERSTORMS WILL IMPACT PORTIONS OF SOUTHWEST
VIRGINIA AND FAR SOUTHERN WEST VIRGINIA THROUGH THE LATE MORNING AND
MIDDAY HOURS.
THE WIDESPREAD CONVECTION THAT OCCURRED EARLIER THIS MORNING HAS
LARGELY STABILIZED THE ATMOSPHERE, LEAVING OVERCAST TO BROKEN
STRATUS IN ITS WAKE. LATEST HIGH RESOLUTION MODEL RUNS ARE LARGELY
IN AGREEMENT TODAY, SHOWING REDEVELOPMENT OF SPOTTY SHOWERS AND
THUNDERSTORMS LATE THIS AFTERNOON, AFTER 20Z. ADDITIONAL SEVERE
POTENTIAL DURING THE LATE AFTERNOON AND EVENING IS QUESTIONABLE, AND
WILL LIKELY DEPEND ON HOW MUCH THE ATMOSPHERE DESTABILIZES LATER
TODAY, IF AT ALL.
MID-LEVEL DRY AIR CAN BE SEEN ON GOES WATER VAPOR IMAGERY ACROSS THE
GREAT LAKES, MOVING NORTH TO SOUTH. THIS DRY AIR SHOULD APPROACH THE
FORECAST AREA SUNDAY, BRINGING DRIER CONDITIONS THROUGH AT LEAST
WEDNESDAY WITH HIGH PRESSURE IN CONTROL.
KEY MESSAGE 2...
MUCH MORE COMFORTABLE AIR FOR EARLY SEPTEMBER WILL RETURN SUNDAY IN
THE WAKE OF A COLD FRONT. EXPECT TEMPERATURES IN THE LOWER TO MIDDLE
80S FOR DAYTIME HIGHS AND DEW POINTS IN THE 60S. THE COMFORTABLE,
LESS HUMID AIR SHOULD STICK AROUND THROUGH AT LEAST TUESDAY. THE 500-
MB RIDGE AXIS WILL SHIFT EASTWARD AGAIN TUESDAY INTO WEDNESDAY,
BRINGING THE RETURN OF HEAT AND HUMIDITY FOR THE SECOND HALF OF THE
WORK WEEK. MODELS SHOW THE POTENTIAL FOR A FEW MID-LEVEL
DISTURBANCES TO CROSS THURSDAY AND FRIDAY, WHICH MAY SIGNAL THE
RETURN OF MORE SHOWERS AND STORMS.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
THE REMAINING ISOLD SHOWERS AND THUNDERSTORMS SHOULD GENERALLY
MOVE OUT OF THE AREA BY 03-06Z. EXPECT THE POSSIBILITY OF BRIEF
MVFR AND IFR RESTRICTIONS ASSOCIATED WITH ANY SHOWER/STORM.
OTHERWISE, AREAS OF FOG AND LOW STRATUS ARE EXPECTED TO DEVELOP
ACROSS THE AREA TONIGHT, WITH WIDESPREAD IFR AND AREAS OF LIFR
RESTRICTIONS POSSIBLE, ALONG WITH LOCAL VLIFR. CONFIDENCE IS
MEDIUM AT THIS POINT IN THE COVERAGE AND EXTENT OF THESE
CONDITIONS.
AFTER 14Z, EXPECTING A RETURN TO VFR CONDITIONS WITH LIGHT
WINDS AREA WIDE, ALTHOUGH MOUNTAINS MAY BE SLIGHTLY SLOWER TO
IMPROVE TO VFR IN SOME SPOTS.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z MONDAY...
FORECAST CONFIDENCE: MEDIUM.
ALTERNATE SCENARIOS: TIMING AND RESTRICTIONS ASSOCIATED WITH
FOG/STRATUS OVERNIGHT AND EARLY SUNDAY MORNING MAY VARY.
