315 PM EDT MON JUN 16 2003

TONIGHT -> TUESDAY

ACTIVE REGIME PERSISTS THRU ENTIRE PERIOD.  STRONG LOW LEVEL JET OF
40KTS CONTINUES TO TRANSPORT ABUNDANT LOW LEVEL MOISTURE INTO THE
AREA.  PWATS ONCE AGAIN TOPS OUT NEAR 1.8 WITH WARM CLOUD DEPTHS OF
12KFT.  SW LOW LEVEL WINDS PUSH FRONT UP TO TUG FORK TONIGHT...WITH
MAIN CONCERN BEING JUST NORTH OF THE BOUNDARY.  RAIN RATES COULD
REACH 2.0 INCHES PER HOUR...SO WILL LET FFA CONT OVERNIGHT.

FRONT CONTINUES TO PUSH NORTH TUESDAY REACHING A UNI-EKN LINE BY
AFTERNOON.  EXPECT SIMILAR CONDITIONS TUESDAY...WHICH ARE OCCURRING
OVER TN/KY THIS AFTERNOON.  PRESENT GRIDS ON TRACK FOR THE MOST
PART...UPPED POPS TO CAT ACROSS SE OH AND SWRN VA THIS
EVENING...BEFORE BRINGING THEM DOWN.  TEMPS ON CUE.

TUESDAY NIGHT>THURSDAY NIGHT
MODELS HAVE COME INTO PRETTY GOOD ALIGNMENT FOR THE MIDDLE PART OF
THE FORECAST.  BOTH MODELS SHOW A STRONG SHORTWAVE MOVING ACROSS THE
REGION TUESDAY NIGHT INTO WEDNESDAY MORNING.  WITH DEEP MOISTURE
REMAINING IN PLACE AND GOOD DIVERGENCE...MOST MORE HEAVY RAIN IS
POSSIBLE TUESDAY NIGHT.  ONCE THE SHORTWAVE PASSES...BOTH ETA/GFS
SHOW GOOD MID LEVEL DRYING.  THIS SHOULD BRING TO AN END THE
ORGANIZED PRECIPITATION...WITH ONLY SCATTERED SHOWERS DUE TO HEATING
REMAIN WEDNESDAY AFTERNOON.

COLD FRONT AND UPPER TROUGH SWING THROUGH DURING THE DAY ON
THURSDAY.  MODELS DO NOT SHOW THE DEEP MOISTURE RECOVERING ENOUGH TO
CAUSE HEAVY RAIN...BUT A LINE OF SHOWERS/TSTORMS IS STILL EXPECTED.
WITH DRIER CONDITIONS FINALLY ANTICIPATED FOR THURSDAY NIGHT.  HAVE
A LITTLE CONCERN ON SPEED OF THE FRONT AND HOW FAR SOUTH IT WILL
ACTUALLY MAKE IT.

FOR TEMPS...GUIDANCE LOOKED TO BE IN THE BALLPARK AND WAS CLOSE TO
PREVIOUS FORECAST SO ONLY SMALL TWEAKS MADE...GETTING NUMBERS CLOSE
TO THE MAV.

FRIDAY THROUGH MONDAY

IN THE LONG RANGE WE CONTINUE TO DRY REGION OUT ON FRIDAY AND
SATURDAY.  MOISTURE MAY START RETURNING FROM SOUTH ON
SUNDAY...INTRODUCED A CHANCE POP FOR SOUTHERN COUNTIES ON DAY 6.
CHANCE ENTIRE COUNTY WARNING AREA FOR DAY 7.

1042 AM EDT MON JUN 16 2003

SURFACE BOUNDARY DRAPED ACROSS I-64 CORRIDOR COUPLED WITH A TROPICAL
AIRMASS AND UPPER FLOW E/SE LESS THAN 10KTS...SETUP IS PRESENT FOR
BACKBUILDING CELLS.  NEARLY STATIONARY CELL ACROSS NORTHERN KANAWHA
COUNTY SINCE 5 AM DUMPING UPWARDS OF 2-3 INCHES AND CREATING LOTS OF
FLOODED ROADS.

FOR THIS AFTERNOON WITH FLOW BACKING TO THE SE ALOFT ACROSS NORTHERN
WEST VIRGINIA AND SOUTHWEST ACROSS THE COAL FIELDS...FEEL BEST
CHANCE REMAINS ALONG AND SOUTH OF I-64.  PWATS REMAIN NEAR 1.7 AND
WARM CLOUD DEPTH OF 11KFT...SO 40 TO 50DBZ (NON-CONVECTIVE CELL)
COULD EASILY PRODUCE NEAR 0.75 INCHES IN AN HOUR.  WITH ALL THE
CLOUDS LOWERED MAX TEMPS A CAT ACROSS THE SOUTH WITH NEAR 80F ACROSS
THE NORTH.

330 AM EDT MON JUN 16 2003

TODAY AND TONIGHT...
SIMILAR SITUATION TONIGHT AS IT WAS THIS TIME LAST NIGHT.  WE REMAIN
IN SAME WARM AND MOIST AIRMASS WITH PW/S WELL OVER 1.5 INCHES.  ONE
DIFFERENCE IS THAT SOME DRIER AIR HAS MOVED INTO THE NORTHERN PART
OF THE AREA AS DEWPOINTS ARE AROUND 60 AND UPPER 50S ACROSS NORTHERN
FRINGES OF CWA.  RADAR CURRENTLY INDICATING SCATTERED SHOWERS ONCE
AGAIN ACROSS SOUTHERN CWA AND PARTS OF SOUTHEAST OHIO.

LOOKING AT YET ANOTHER DAY OF RAIN AND POTENTIAL PROBLEMS DEPENDING
ON WHERE ORGANIZATION TAKES PLACE.  WITH FRONTAL BOUNDARY ACROSS
NORTHERN CWA AND WEAK UPPER ENERGY EXPECTED TO MOVE INTO REGION
TODAY FROM SOUTHWEST...HAVE GRADIENT IN POP FIELD FROM NORTHEAST TO
SOUTHWEST WITH CHANCE POPS IN NORTHEAST TO LIKELY SOUTHWEST.
GRADUALLY LOWER POPS TO CHANCE ALL LOCATIONS OVERNIGHT WITH LOSS OF
DAYTIME HEATING BUT THERE WILL CERTAINLY BE POTENTIAL FOR NOCTURNAL
SHOWERS.  AFTER COORDINATION WITH SURROUNDING OFFICES...HAVE ALSO
EXTENDED CURRENT FLOOD WATCH UNTIL 4 AM TUES MORNING AS ANY
ORGANIZED SHOWERS AND THUNDERSTORMS COULD CAUSE PROBLEMS WITH
SATURATED GROUNDS.  THINK THERE IS POSSIBILITY FOR WATCH TO BE
EXTENDED INTO TUES BUT AT THIS TIME WITHIN THIS MESOSCALE DRIVEN
ENVIRONMENT DECIDED TO GO ONE DAY AT A TIME.

LEANED TOWARD THE WARMER FWC/MET GUIDANCE FOR TEMPS TODAY THINKING
THAT WITH A FEW BREAKS IN CLOUDS AND SUN WE COULD EASILY REACH UPPER
70S TO NEAR 80 AS WE WILL BE STARTING DAY IN UPPER 60S.  WENT
TOWARDS WARMER FWC/MET GUIDANCE FOR LOWS TONIGHT AS WELL THINKING
CLOUDS AND HIGH DEWPOINTS WILL KEEP TEMPS UP.

TUESDAY THROUGH SUNDAY...
MODELS IN REASONABLE AGREEMENT THAT A STRONG ENOUGH SHORT WAVE WILL
SWEEP ACROSS THE REGION TUESDAY AND TUESDAY NIGHT...HELPING TO PUSH
OUT MUCH OF THE MID AND UPPER LEVEL MOISTURE CURRENTLY OVER THE
AREA.  BEFORE THIS HAPPENS...THIS FEATURE WILL ENHANCE CONVECTION
TUESDAY AND TUESDAY NIGHT.  A COLD FRONT WITH A STRONGER SHORT WAVE
WILL CROSS THE AREA THURSDAY WITH SCATTERED CONVECTION.  HIGH
PRESSURE WITH DRIER AND COOLER AIR FINALLY TAKES CONTROL FRIDAY
THROUGH THE WEEKEND. MOS GUIDANCE PROBABLY A TOUCH TOO HIGH GIVEN
THE ALL THE MOISTURE...CLOUDS AND IMPENDING CONVECTION THROUGH
WEDNESDAY. OTHERWISE...TEMPERATURE GUIDANCE FOLLOWED AS A GENERAL
RULE.
