AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
240 PM EDT FRI JUL 10 2026
WHAT HAS CHANGED
LITTLE TO NO CHANGE WITH THE AFTERNOON FORECAST PACKAGE
REGARDING THIS WEEKEND. FLOOD WATCH REMAINS INTACT FOR THE BULK
OF THE AREA THROUGH SUNDAY MORNING.
MORNING AND EARLY AFTERNOON CLOUD COVERAGE HAS LIMITED STRONG
DAYTIME HEATING FROM OCCURRING, KEEPING HOURLY TEMPERATURES
LOWER THAN PREVIOUSLY ANTICIPATED AND CONVECTIVE TRENDS LOW THUS
FAR TODAY.
KEY MESSAGES
1) A FRONTAL BOUNDARY PROGGED TO DRIFT DOWN AND STALL OVER THE
AREA WILL SERVE UP UNSETTLED WEATHER FOR AT LEAST THE FIRST HALF
OF THE WEEKEND. HEAVY SHOWERS AND ISOLATED STRONG TO POTENTIALLY
SEVERE THUNDERSTORMS COULD LEAD TO LOCALIZED FLASH FLOODING
THROUGH SUNDAY MORNING.
2) BECOMING DRIER FOR THE START OF THE WORK WEEK, TURNING HOTTER
BY MIDWEEK.
DISCUSSION
KEY MESSAGE 1...
RADAR AND SATELLITE TRENDS THIS AFTERNOON SHOW MUCH OF THE
FORECAST AREA ENTRENCHED BENEATH A LOW TO MID-LEVEL CLOUD DECK
EMBEDDED WITH STRATIFORM RAIN. THIS HAS KEPT TEMPERATURES A FEW
DEGREES BELOW CENTRAL GUIDANCE AND INSTABILITY AT A MINIMUM THUS
FAR TODAY. CONVECTIVE TRENDS AT THE TIME OF WRITING HAVE BEGUN
TO BUILD UPWARD ACROSS PORTIONS OF CENTRAL VIRGINIA EAST OF THE
PERSNICKETY STRATUS DECK. NORTH OF OUR FORECAST AREA, MORNING
AND AFTERNOON CLEAR SKIES HAS RESULTED IN ANOTHER AREA SCATTERED
SHOWER AND STORM DEVELOPMENT, WHICH WILL NEED TO BE MONITORED
THROUGH THE COURSE OF THE AFTERNOON AS ACTIVITY SINKS SOUTHWARD.
THIS IS THE RESULT OF A SLOW SOUTHWARD PROGRESSION OF A FRONTAL
BOUNDARY ORIENTED FROM WEST TO EAST FROM THE UPPER OHIO VALLEY
INTO PENNSYLVANIA.
WITH THE FRONT SLATED TO PARK OVER THE CENTRAL APPALACHIANS BY
OVERNIGHT TONIGHT INTO THE START OF THE WEEKEND, UNSETTLED
WEATHER IS PROGGED TO FESTER FOR THE BULK OF THE FORECAST AREA.
18Z MESOANALYSIS PLANTS THE AREA WITHIN 1.8 TO 2 INCH PWATS,
MAINTAINING STRONG SIGNALS FOR HEAVY DOWNPOURS WITHIN ANY SHOWER
AND STORM AIMING DOWN FROM THE NORTH OR ADDITIONAL DEVELOPMENT
ACROSS SOUTHEAST OHIO CURRENTLY UNDERGOING CLEARING SKIES. THE
FORECAST REMAINS RELATIVELY UNCHANGED FROM PREVIOUS CYCLES,
SUGGESTING A BURST OF SHOWERS AND STORMS ENTERING INTO OUR FAR
NORTHWESTERN ZONES IN THE NEXT FEW HOURS THEN PETERING OUT WITH
THE LOSS OF DAYTIME HEATING.
SHOWER AND THUNDERSTORM COVERAGE WILL RETURN IN EARNEST ON
SATURDAY AFTERNOON, FIRING UP ALONG THE FRONT POSITIONED
OVERHEAD. HI-RES CONVECTIVE MODELS DEPICT INITIAL DEVELOPMENT
OVER THE TRI-STATE AREA SHORTLY AFTER MIDDAY, THEN SPREADING
FURTHER ACROSS THE LOWLANDS AND MOUNTAINS DURING PEAK HEATING
HOURS. THE FRONT WILL THEN PUSH SOUTHWARD SOME MORE ON SUNDAY,
WITH SHOWER AND STORM CHANCES BECOMING MORE CONFINED TO OUR
SOUTHERN AND MOUNTAINOUS COUNTIES DURING THE AFTERNOON BEFORE
CLEARING OUT FOR THE START OF THE NEW WORK WEEK.
WHILE STRONG TO DAMAGING WIND GUSTS MAY BE ATTACHED TO
THUNDERSTORMS TODAY AND SATURDAY, THE BIGGER CONCERN WITH
ACTIVITY THIS WEEKEND WILL BE THE QUICK BURSTS OF RAIN AND/OR
REPETITIVE SHOWERS AND STORMS FALLING OVER ALREADY SATURATED
SOILS. THERE REMAINS A VARIETY OF MODEL OUTPUTS IN REGARDS TO
FORECAST RAINFALL ACCUMULATIONS, BUT FLASH FLOODING WILL BE
INCREASINGLY POSSIBLE FOR LOCATIONS THAT DO OBSERVE HEAVY
SHOWERS AND STORMS. A FLOOD WATCH WILL REMAIN IN PLACE THROUGH
SUNDAY MORNING AMID THIS MUDDLED WEATHER PATTERN. SOME GUIDANCE
TARGETS A SWATH OF HEAVIER RAIN THROUGH THE SOUTHERN COALFIELDS
ON SATURDAY AFTERNOON, WHICH COULD BE TROUBLESOME DUE TO
RAINFALL THAT HAS ALREADY OCCURRED IN THIS AREA WITHIN THE PAST
FEW WEEKS.
KEY MESSAGE 2...
ONCE THE FRONT JOURNEYS FURTHER SOUTHWARD TOWARDS THE GULF COAST
ON MONDAY, A DRIER PATTERN IS EXPECTED TO TAKE HOLD. UPPER
HEIGHT RISES NOSING IN FROM THE SOUTH BY MIDWEEK SUGGESTS
WARMING TEMPERATURES AND HUMIDITY, WHICH COULD BOLSTER HEAT
INDICES STRETCHING INTO THE MID TO UPPER 90S FOR PARTS OF THE
LOWLANDS. THERE ARE SIGNALS FOR RENEWED PRECIPITATION
POTENTIALLY ARRIVING BY THE END OF THE WEEK, BUT GUIDANCE
REMAINS UNCERTAIN ON TIMING AND MAGNITUDE OF THE SYSTEM.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
FLIGHT RESTRICTIONS PERSIST THROUGH THE COURSE OF THE TAF PERIOD
AMID A SAGGING FRONTAL BOUNDARY AND THE ACCOMPANIMENT OF SHOWERS
AND THUNDERSTORMS. CEILING RESTRICTIONS WILL HOLD STEADY THROUGH
SATURDAY AS THE FRONT PARKS OVERHEAD WHILE VISIBILITY
RESTRICTIONS WILL BE INTERMITTENT AND DEPENDENT ON THE INTENSITY
OF PASSING SHOWERS AND STORMS. ADDITIONALLY, FOG DEVELOPMENT
SATURDAY MORNING WILL EXACERBATE ONGOING RESTRICTIONS ACROSS
MOST TAF SITES. MUCH OF THE SAME FLIGHT CONDITIONS ARE EXPECTED
ON SATURDAY AMID HEAVY SHOWERS AND THUNDERSTORMS.
SURFACE FLOW THIS AFTERNOON HAS REMAINED STEERED OUT OF THE
SOUTH/SOUTHWEST BETWEEN 5 TO 10 KNOTS, AND IS ANTICIPATED TO
GROW CALM OVERNIGHT INTO SATURDAY AS THE FRONT DRAPES ACROSS THE
AREA.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SATURDAY...
