AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
236 PM EDT SAT JUL 11 2026
WHAT HAS CHANGED
ELECTED TO EXTEND THE FLOOD WATCH ACROSS PARTS OF KY, WV, AND VA
INTO LATE SUNDAY EVENING TO ACCOUNT FOR THE SLOW DEPARTURE OF
THE COLD FRONT. ACROSS OUR NORTHERN ZONES, FLASH FLOODING
CONCERNS DIMINISH AFTER TONIGHT, SO THE WATCH REMAINS ON
SCHEDULE TO EXPIRE SUNDAY MORNING.
KEY MESSAGES
1) FLASH FLOODING CONCERNS SPILL INTO SUNDAY AMID A SLOW
DEPARTURE OF A COLD FRONT. SLOW MOVING SHOWERS AND STORMS
CONTAINING HEAVY DOWNPOURS WILL EXACERBATE ALREADY SATURATED
SOILS TODAY AND SUNDAY.
2) TURNING DRY AND WARMER FOR THE NEW WEEK BEFORE RETURNING TO
AN UNSETTLED STATE AFTER THURSDAY.
DISCUSSION
KEY MESSAGE 1...
AFTERNOON RADAR TRENDS HAVE RAMPED UP OVER THE PAST FEW HOURS
UNDER THE GUISE OF EMBEDDED SHORTWAVE ENERGY RIDING ALONG A
WEST-EAST ORIENTED FRONTAL BOUNDARY DRAPED JUST NORTH OF THE
FORECAST AREA. THIS PLACES THE BULK OF THE CENTRAL APPALACHIANS
WITHIN A HUMID AND UNSTABLE ENVIRONMENT CONDUCIVE FOR THE RAPID
DEVELOPMENT OF SHOWERS AND STORMS TODAY INTO THIS EVENING. THESE
SLOWLY PROPAGATING CELLS CONTAINING HEAVY DOWNPOURS EQUIVALENT
TO 1-3"/HR WILL PROVOKE ALREADY SATURATED SOILS AND LEAD TO
AREAS OF FLASH FLOODING. THERE HAS ALREADY BEEN EVIDENCE OF
THESE HEAVY RAIN PRODUCERS ACROSS PARTS OF SOUTHEAST OHIO AS
WELL AS OUR SOUTHERN COALFIELDS TODAY, LEADING TO SEVERAL
REPORTS OF FLOODED ROADWAYS. CONCERNS FOR ADDITIONAL FLASH
FLOODING CONTINUES THROUGH THE DAYTIME HOURS BEFORE GRADUALLY
DIMINISHING WITH THE LOSS OF DAYTIME HEATING.
THE QUASI-STATIONARY FRONT WILL SLOWLY PROPAGATE SOUTHWARD
OVERNIGHT INTO SUNDAY, BUT WILL FAIL TO MAKE A FULL EXODUS FROM
THE AREA. AS A RESULT, SHOWER AND STORM COVERAGE WILL APPEAR
ONCE MORE ACROSS THE SOUTHERN HALF OF THE CWA FOR SUNDAY
AFTERNOON. WITH LITTLE TO NO CHANCE FOR SOIL RECOVERY ACROSS THE
COALFIELDS, OPTED TO EXTEND THE FLOOD WATCH FOR NORTHEAST
KENTUCKY, SOUTHERN WEST VIRGINIA, AND SOUTHWEST VIRGINIA THROUGH
SUNDAY EVENING TO ACCOUNT FOR THE ADDITIONAL RAINFALL POTENTIAL.
OUR NORTHERN ZONES WILL BECOME LESS SUSCEPTIBLE TO FLASH
FLOODING ON SUNDAY IN RESPONSE TO THE SOUTHWARD TRAJECTORY OF
THE FRONTAL BOUNDARY, ALLOWING THE CURRENT WATCH TO EXPIRE
SUNDAY MORNING.
KEY MESSAGE 2...
ONCE THE FRONTAL BOUNDARY SLIPS SOUTHWARD TOWARDS THE GULF COAST
BEGINNING ON MONDAY, DRIER WEATHER TAKES HOLD AMID UPPER LEVEL
RIDGING TAKING CENTER STAGE. THIS FEATURE WILL YIELD A WARMING
TREND, RETURNING AFTERNOON HIGH TEMPERATURES INTO THE MID TO
UPPER 90S FOR MUCH OF THE LOWER ELEVATIONS. COUPLED WITH
SLIGHTLY INCREASING MOISTURE/HUMIDITY, HEAT INDICES NOSE UP
INTO THE UPPER 90S BY MIDWEEK. UNCERTAINTY STILL LIES IN THE
LATTER HALF OF THE WEEK FORECAST PERIOD, WHERE PERIODIC
DISTURBANCES BRING UNSETTLED WEATHER BACK TO THE AREA.
AVIATION /18Z SATURDAY THROUGH THURSDAY/
SCATTERED SHOWER AND THUNDERSTORM DEVELOPMENT IS UNDERWAY THIS
AFTERNOON, LEADING TO BRIEF SURFACE VISIBILITY RESTRICTIONS.
MVFR CLOUD DECK THAT HAS PERMEATED OVER THE AREA THIS MORNING
HAS BEGUN TO ERODE, ALLOWING FOR CONVECTIVE DEVELOPMENT TO
TRANSPIRE. AFTER SUNSET, STORM ACTIVITY WILL DIMINISH AND GIVE
WAY TO ANOTHER NIGHT OF IFR/LIFR POTENTIAL AMID LOW STRATUS,
FOG, AND LINGERING SHOWERS HEADING INTO SUNDAY MORNING. LIGHT
AND VARIABLE SURFACE WINDS RULE THE ROOST THROUGH THE TAF
PERIOD, BUT ISOLATED THUNDERSTORM WIND GUSTS COULD NOSE INTO OUR
TERMINALS THIS AFTERNOON.
