Special Weather Statement, NWS Charleston, WV

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
731 PM EDT SAT JUL 18 2015

.SYNOPSIS...
THE HOT AND HUMID WEEKEND CONTINUES WITH SCATTERED AFTERNOON
CONVECTION. A COLD FRONT APPROACHES LATE SUNDAY AND WILL BE IN
THE VICINITY EARLY IN THE WORK WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
730 PM UPDATE...ISOLATED TO SCATTERED THUNDERSHOWERS DRIFTING ESE
ACROSS CWA. EXPECT THESE TO GRADUALLY DECREASE IN INTENSITY AND
COVERAGE THROUGH THE LATE EVENING AND EARLY OVERNIGHT. LOTS OF
OUTFLOW BOUNDARY INTERACTION GOING ON MAY KEEP THINGS GOING A BIT
LONGER THAN TYPICAL DIURNAL CONVECTION. WHERE IT HAS NOT STORMED
STILL HAVE MID TO UPPER 80S...BUT AFTER A TSHOWER GOES THROUGH
TEMPS ARE GENERALLY DROPPING INTO THE UPPER 70S BRIEFLY BEFORE
GRADUALLY CLIMBING BACK INTO THE LOW OT MID 80S.

PREVIOUS DISCUSSION...
THUNDERSTORMS FORMING OUT AHEAD OF A WEAK UPPER LEVEL S/W TROUGH
MAY APPROACH THE MIDDLE OHIO VALLEY TONIGHT. OTHER SCATTERED
CONVECTION WAS NOTED NEAR THE TUG FORK.  OTHERWISE CONVECTION
SHOULD REMAIN LIMITED MAINLY TO THE MOUNTAINS AS DRIER AIR PUSHES
IN FROM THE W. TONIGHT SHOULD BE RELATIVELY QUIET WITH UPPER LEVEL
RIDGING AND SAID DRY AIR IN PLACE.

SUNDAY SHOULD START MUCH LIKE TODAY WITH A REPEAT OF THE HEAT AND
HUMIDITY. HOWEVER...A STRONGER UPPER LEVEL S/W TROUGH IS LIKELY TO
GET CONVECTION FIRING YUP IN THE AFTERNOON AND MOVING INTO THE
MIDDLE OHIO VALLEY BY THE END OF THE DAY. MODEL TIMING ON THIS IS
GENERALLY SLOWER ON THIS COMPARED WITH PREVIOUS RUNS.

ELSEWHERE...SCATTERED AFTERNOON CONVECTION WILL SOMEWHAT FAVOR
THE MOUNTAINS SUNDAY ON ELEVATED HEAT SOURCE.

BLENDED IN MET AND MAV FOR TEMPERATURES AND DEW POINTS FOR NOT
MUCH CHANGE. THIS LEAVES PEAK HEAT INDICES IN THE MID TO UPPER
90S SUNDAY AFTERNOON.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
FRONTAL BOUNDARY WILL APPROACH THE AREA SUNDAY NIGHT INTO
MONDAY...EVENTUALLY STALLING OUT ACROSS THE AREA ON MONDAY...WITH
ANOTHER FRONT PUSHING THROUGH BY MID WEEK. THE AREA WILL BE STUCK
IN A WARM...HUMID AND UNSTABLE PATTERN...WITH SHOWERS AND
THUNDERSTORMS LIKELY...PARTICULARLY DURING PEAK HEATING HOURS.
WITH THE HIGH MOISTURE CONTENT OF THE AIR...EXPECT HEAVY
DOWNPOURS...AND THE POSSIBILITY FOR LOCALIZED WATER ISSUES. WILL
CONTINUE TO KEEP THIS HIGHLIGHTED IN THE HWO.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
COLD FRONT WILL PUSH EAST OF THE AREA BY WEDNESDAY MORNING. MODELS
ARE ACTUALLY STARTING TO TREND TOWARDS A DRIER...AND SOMEWHAT
COOLER SOLUTION FOR MID TO LATE WORK WEEK...WITH HIGH PRESSURE
BUILDING IN FROM THE NORTH BEHIND THE FRONT. HOWEVER...BY THE
WEEKEND...IF NOT SOONER...MOISTURE MAY TRY TO WORK ITS WAY NORTH
AGAIN...PARTICULARLY ACROSS THE HIGHER TERRAIN COUNTIES AS THE
HIGH SLIDES OFF TO THE EAST.

&&

.AVIATION /23Z SATURDAY THROUGH THURSDAY/...
SCATTERED CONVECTION SHOULD GRADUALLY DECREASE IN COVERAGE AND
INTENSITY AS WE HEAD INTO TONIGHT. A LOT OF OUTFLOW BOUNDARIES
VISIBLE ON RADAR...WHICH WILL CAUSE SOME FAIRLY UNPREDICTABLE VARIABILITY
TO WINDS INTO TONIGHT. SHOULD A TSHOWER CROSS A TAF SITE...EXPECT
BRIEF IFR VISIBILITY...AND WILL HANDLE WITH AMENDMENTS AS THE
EVENING CONTINUES.

MUCH LIKE LAST NIGHT...THINK WE SHOULD AVOID DENSE FOG MOST
PLACES. HOWEVER WITH HIGHER COVERAGE OF RAIN...MAY SEE MORE FOG
THAN LAST NIGHT.

EXPECT VFR CONDITIONS TOMORROW...WITH SCATTERED SHOWERS AND
THUNDERSTORMS BY AFTERNOON. COULD GET MVFR TO IFR IN THESE IF THEY
IMPACT A TAF SITE.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z MONDAY...

FORECAST CONFIDENCE: MEDIUM.

ALTERNATE SCENARIOS...
BRIEF MVFR TO IFR POSSIBLE IN SHOWERS/STORMS EARLY TONIGHT AND
AGAIN SUNDAY AFTERNOON. DENSITY AND TIMING OF FOG TONIGHT MAY
VARY. BRIEF MVFR CIGS MAY OCCUR AS THE CU STARTS TO FORM MIDDAY
SUNDAY.

AFTER 00Z MONDAY... IFR IN MORE WIDESPREAD SHOWERS/STORMS SUNDAY
NIGHT OR MONDAY WITH FRONT IN THE AREA.

&&

.RLX WATCHES/WARNINGS/ADVISORIES...

OH...NONE.
