AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON KY
250 PM EDT SAT JUL 30 2011

.SHORT TERM.../TONIGHT THROUGH MONDAY/...UPDATED

18Z SFC ANALYSIS SHOWS AN AREA OF LOWER PRESSURE ACROSS NORTHERN
KENTUCKY IN ASSOCIATION WITH A SLOWLY SINKING COLD FRONT. THIS
BOUNDARY HAS REACTIVATED EARLY THIS AFTERNOON WITH SLOW MOVING AND
SOMEWHAT BACK BUILDING THUNDERSTORMS ENTERING THE WESTERN PORTION OF
THE CWA. THESE HAVE ALREADY PROMPTED A COUPLE URBAN AND SMALL STREAM
FLOOD ADVISORIES TO BE ISSUED AS RADAR ESTIMATES OF RAINFALL TOP TWO
AND THREE INCHES IN LESS THAN A COUPLE HOURS IN PARTS OF JACKSON AND
ESTILL COUNTIES. ADDITIONAL TRAINING STORMS COULD LEAD TO FLASH
FLOODING IN THESE AREAS. OTHERWISE...THE BREAKS IN THE CLOUDS ALLOWED
TEMPERATURES TO CLIMB INTO THE UPPER 80S AND LOWER 90S AGAIN THIS
AFTERNOON ADDING TO THE FUEL FOR THE STORMS. DEWPOINTS ARE HOLDING IN
THE LOWER 70S...AS WELL...EVIDENCE OF THE HIGH PW AIR IN PLACE AND
THE CONTINUED POTENTIAL FOR EXCESSIVE RAINFALL. CLOUD TOPS ARE ALSO
CONTINUING TO COOL OVER THE AREA SUGGESTING THAT THESE STORMS WILL
INCREASE IN COVERAGE AND PERHAPS INTENSITY OVER THE NEXT FEW HOURS.

THE MODELS ARE IN GOOD AGREEMENT ALOFT AS THE SEMI-PERSISTENT RIDGE
IS SHUNTED INITIALLY TO THE SOUTH TODAY AND THEN INCREASINGLY TO THE
SOUTHWEST TONIGHT AND ON SUNDAY. THIS TRANSITION WILL ALLOW FOR A
SERIES OF SHORTWAVES TO PASS THROUGH EASTERN KENTUCKY DURING THE
SHORT TERM PORTION OF THE FORECAST. THE FIRST OF THESE IS RESPONSIBLE
FOR THE BLOSSOMING STORMS WE ARE SEEING ACROSS THE AREA THIS
AFTERNOON. THE NEXT ONE WILL PASS THROUGH SUNDAY MORNING AND LIKELY
HELP HOLD UP THE FRONT/S GRADUAL PROGRESSION THROUGH THE CWA ON
SUNDAY. THE HEIGHT FALLS ACCOMPANYING THESE WAVES WILL ALSO SUPPORT
THE HIGHER RAIN CHANCES THROUGH SUNDAY. FOR MONDAY...THE RIDGE
STRENGTHENS TO OUR WEST AND SHOULD BE ENOUGH TO KEEP THE MINOR WAVES
ALOFT OFF TO THE NORTHEAST. HAVE FOLLOWED A GENERAL MODEL BLEND FOR
THE MAIN FEATURES IN THE SHORT TERM WHILE USING THE HIGHER RESOLUTION
NAM12 FOR WEATHER SPECIFICS.

SENSIBLE WEATHER WILL FEATURE A STORMY LATE AFTERNOON AND EARLY
EVENING AS THE DIURNAL CONVECTIVE CYCLE CORRESPONDS TO THE FRONTAL
BOUNDARY LYING JUST NORTH OF THE CWA. FROM THIS...EXCESSIVE RAINFALL
WILL CONTINUE TO BE THE PRIMARY CONCERN DUE TO HIGH PWS AND SLOW
STORM MOTION...ALONG WITH THE STRONG POTENTIAL FOR TRAINING CELLS.
THE CONVECTION SHOULD BECOME MORE SCATTERED AND WEAKER LATER THIS
EVENING AS THE HEAT OF THE DAY EBBS. HOWEVER...THE ADDED MOISTURE
WILL LIKELY LEAD TO WIDESPREAD AREAS OF FOG WHERE IT RAINED AND
EVENTUALLY POCKETS OF DENSE FOG. WILL ADD THIS CONCERN TO THE HWO
FOR TONIGHT BUT LEAVE IT FOR THE FOLLOWING SHIFT TO MONITOR FOR A
POSSIBLE DENSE FOG ADVISORY. THE FRONT WILL SLOWLY TRY TO CLEAR THE
CWA ON SUNDAY...BUT KEEP THE THREAT OF SHOWERS AND THUNDERSTORMS
GOING FOR AT LEAST THE SOUTHERN PORTION OF EAST KENTUCKY WELL INTO
THE AFTERNOON...AGAIN CORRESPONDING TO THE DIURNAL CONVECTIVE CYCLE.
HAVE DRAWN THE POP GRIDS ACCORDINGLY. THE SLIGHTLY DRIER AIR AND
BUILDING SFC HIGH PRESSURE WILL EVENTUALLY PUSH THE FRONT FAR ENOUGH
SOUTH SUNDAY NIGHT TO REMOVE POPS AND ALLOW FOR A TAD COOLER NIGHT
TIME LOWS...THOUGH THE THREAT OF FOG...LOCALLY DENSE...WILL CONTINUE
INTO MONDAY MORNING. FOR MONDAY PROPER...A DRY AND WARM DAY IS
EXPECTED UNDER THE HIGH PRESSURE AREA DROPPING INTO THIS PART OF THE
STATE FROM THE NORTHWEST.

FOR TEMPERATURES...LEANED TOWARD VALUES SLIGHTLY WARMER THAN THE MET
THROUGH THE PERIOD OWING TO THE RECENT TRENDS AND RELATIVE WEAKNESS
OF THE HIGH MOVING IN LATE IN THE PERIOD. AGAIN ONLY MINOR TERRAIN
DETAILS WERE ADDED AT NIGHT GIVEN THE HIGH HUMIDITY. AS FOR POPS...
THE HIGHER MET NUMBERS MATCHED UP BEST WITH MY GRIDS THROUGH
SUNDAY...THEN KEPT IT DRY INTO MONDAY.

.LONG TERM.../MONDAY NIGHT THROUGH SATURDAY/...UPDATED

OUR AREA WILL REMAIN ON THE NORTHEAST PERIPHERY OF A SPRAWLING UPPER
RIDGE WHICH WILL REMAIN ANCHORED OVER THE SOUTHERN PLAINS THROUGH
THE FORECAST PERIOD. EMBEDDED SHORT WAVES WITHIN A NEARLY ZONAL BAND
OF WESTERLY FLOW ACROSS THE NORTHERN CONUS WILL TEND TO FLATTEN THIS
RIDGE WITH TIME AS THE CORE OF THE WESTERLIES BUILDS SOUTHWARD
SLIGHTLY.

A COUPLE OF THESE DISTURBANCES WILL MOVE ACROSS THE OHIO VALLEY AND
MAY PROVIDE A LITTLE EXTRA CLOUD COVER EVEN A FEW SHOWERS AND STORMS
ON THURSDAY.  BASED ON THE LATEST RUNS OF THE GFS AND ECMWF
MODELS...IT LOOKS LIKE THE FIRST REAL OPPORTUNITY OF RAIN NEXT WEEK
WILL ARRIVE BY MID MORNING THURSDAY. A DIURNAL TREND TO THE
PRECIPITATION LOOKS LIKE A GOOD BET...AS WE ARE IN A TYPICAL SUMMER
TIME PATTERN WITH A VERY WARM AND MOIST AIR MASS IN PLACE. DECIDED
TO KEEP THE FORECAST DRY UNTIL EARLY THURSDAY MORNING...WHEN A
RELATIVELY WEAK SFC COLD FRONTAL BOUNDARY MANAGES TO DROP CLOSE
ENOUGH TO OUR AREA TO PROVIDE A THREAT OF RAIN. THE FRONT THEN
STALLS OUT ACROSS THE AREA UNTIL A SECOND DISTURBANCE PUSHES THROUGH
THE REGION FRIDAY...POSSIBLY DRAGGING THE FRONT THROUGH THE AREA.
THIS WILL KEEP THE THREAT OF RAIN IN THE FORECAST THROUGH TO THE END
OF THE EXTENDED PERIOD.

MADE CORRESPONDING CHANGES TO THE WEATHER...SKY COVER...AND QPF
GRIDS BASED ON THE CHANGES MADE TO THE POP FORECAST. A FEW
ADJUSTMENTS WERE ALSO MADE ACROSS THE BOARD TO THE TEMPERATURE
FORECAST...GOING A DEGREE OR SO WARMER ACROSS THE BOARD PER THE
LATEST HPC AND MEXMOS GUIDANCE.

&&

.AVIATION.../18Z TO 18Z/

CLUSTERS OF SHOWERS AND THUNDERSTORMS ARE DEVELOPING THROUGH EAST
KENTUCKY JUST ABOUT ON TRACK WITH EARLIER EXPECTATIONS. IN FACT...THE
ONGOING TAFS WITH TEMPOS FOR STORMS BETWEEN 18 AND 22Z LOOK IN
PRETTY GOOD SHAPE. KEPT THIS IDEA GOING WITH IFR CONDITIONS POSSIBLE
DURING ANY THUNDERSTORM THIS AFTERNOON. THE CONVECTION SHOULD BECOME
MORE SCATTERED DURING THE EVENING AND SO HAVE DROPPED BACK TO VCTS AT
THIS POINT. LATER TONIGHT...EXPECT FOG TO THICKEN THROUGH MOST OF THE
AREA WITH LIFR CONDITIONS POSSIBLE AT ALL SITES DURING THE PREDAWN
HOURS. AT THE SAME TIME...THE THREAT FOR SHOWERS OR A STRAY
THUNDERSTORM WILL CONTINUE THROUGH MIDDAY SUNDAY AS THE FRONTAL
BOUNDARY WILL ONLY SLOWLY MAKE ITS WAY SOUTH THROUGH THE FORECAST
AREA. OUTSIDE OF ANY THUNDERSTORM...WINDS WILL BE LIGHT AND VARIABLE
WITH GUSTS TO 25 KTS POSSIBLE DURING ANY STORM.
