DISCUSSION
KEY MESSAGE 1...
ROUNDS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED THROUGHOUT
THE REST OF THE WORK WEEK AND THE WEEKEND AS A VERY MOIST
AIRMASS REMAINS IN PLACE, WITH A LINGERING FRONTAL BOUNDARY AND
PERIODIC CROSSING UPPER WAVES PROVIDING SYNOPTIC SCALE
ENHANCEMENT AT TIMES. GUIDANCE CONTINUES TO FORECAST PWATS IN
THE 1.5 TO 2.0" RANGE INTO THE WEEKEND, RESULTING IN THE
POTENTIAL FOR LOCALIZED FLASH FLOODING.
SCATTERED SHOWERS AND STORMS ARE ONGOING ACROSS THE REGION THIS
AFTERNOON AS A MODEST SHORTWAVE TRAVERSES ACROSS THE AREA.
SHOWER/STORM MOTION IS FAIRLY PROGRESSIVE, BUT GIVEN RATES OF
1"+ PER HOUR, LOCALIZED FLASH FLOODING IS POSSIBLE GIVEN ANY
TRAINING OF CONVECTION. ACTIVITY SHOULD BEGIN TO STEADILY
DISSIPATE LATER THIS EVENING, WITH MAINLY DRY CONDITIONS
OVERNIGHT, ALTHOUGH SOME SHOWERS COULD MOVE IN LATE TONIGHT
ACROSS THE WEST AND NORTH. A BIT OF PATCHY FOG IS POSSIBLE
ACROSS SOUTHERN/EASTERN WV DEPENDING ON CLEARING.
THE MOST WIDESPREAD RAINFALL IS EXPECTED ON FRIDAY AS A COLD
FRONT SLOWLY APPROACHES FROM THE NORTH AND A MORE ROBUST
SHORTWAVE CROSSES OVERTOP. MOTION OF SHOWERS/STORMS GIVEN H850
FLOW SHOULD BE SIMILAR TO THAT OF TODAY, BUT WITH PERHAPS A BIT
MORE TRAINING POTENTIAL. ANOTHER CROSSING SHORTWAVE ON SATURDAY
COMBINED WITH THE LINGERING SURFACE BOUNDARY WILL RESULT IN
MORE SHOWERS AND STORMS, BUT PERHAPS A BIT FURTHER SOUTH, ACROSS
THE CENTRAL/SOUTHERN CWA. RAINFALL ON SUNDAY SHOULD MAINLY BE
CONFINED TO THE EASTERN/SOUTHERN PORTION OF THE CWA AS THE
SURFACE BOUNDARY CONTINUES TO SLIDE SOUTHWARD, WITH MAINLY DRY
WEATHER SUNDAY NIGHT INTO EARLY NEXT WEEK.
GIVEN THE LOCALLY HEAVY RAINFALL YESTERDAY (1-2" IN SOME
AREAS), ANTICIPATED ADDITIONAL ROUNDS OF RAINFALL, AND AFTER
COLLABORATION WITH NEIGHBORING OFFICES, HAVE ISSUED A FLOOD
WATCH FOR FLASH FLOODING THROUGH 8 AM SUNDAY FOR MUCH OF THE
CWA.
WHILE ORGANIZED SEVERE WEATHER IS NOT ANTICIPATED, GIVEN
PROGGED MIXED-LAYER CAPE IN EXCESS OF 1,000 J/KG EACH
AFTERNOON/EVENING AND MODEST 0-6KM SHEAR, ISOLATED STRONG
STORMS CANNOT BE RULED OUT. THE HAZARD ASSOCIATED WITH ANY HEAVY
STORMS WOULD BE STRONG WIND GUSTS.
KEY MESSAGE 2...
BUILDING HIGH PRESSURE FROM THE NORTH AND EAST FOLLOWING THE
PASSAGE OF A COLD FRONT LATE THIS WEEKEND WILL RESULT IN A MUCH
DRIER SUNDAY NIGHT AND START TO THE NEW WORK WEEK. NEAR
SEASONABLE TEMPERATURES ARE EXPECTED.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
SOME MVFR OR WORSE RESTRICTIONS WILL BE POSSIBLE IN FOG AND LOW
CLOUDS EARLY THIS MORNING, THOUGH THE EXTENT OF FOG MAY BE
SOMEWHAT LIMITED BY INCREASING CLOUD COVER AND WINDS JUST ABOVE
THE SURFACE. SHOWERS AND STORMS WILL MOVE BACK INTO THE AREA
THIS MORNING AND THEN PERSIST THROUGH THE MAJORITY OF THE DAY.
PERIODIC IFR CIGS/VIS ARE EXPECTED TO OCCUR WITHIN ANY HEAVIER
SHOWERS OR STORMS. RESTRICTIONS REMAIN POSSIBLE AFTER 00Z AMID
CONTINUED PRECIPITATION, FOG, AND STRATUS.
SURFACE FLOW WILL GENERALLY BE LIGHT WITH A SOUTH TO SOUTHWEST
DIRECTION; HOWEVER, LOCALLY STRONG GUSTS MAY OCCUR WITHIN ANY
STORMS.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SATURDAY...
FORECAST CONFIDENCE: MEDIUM.
ALTERNATE SCENARIOS: RESTRICTIONS TONIGHT WITH FOG AND/OR
STRATUS MAY BE WORSE THAN CURRENTLY FORECAST. TIMING AND
