AT 156 AM EDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO
INDICATE NEARLY STATIONARY THUNDERSTORMS PRODUCING RAINFALL RATES
UP TO 2 INCHES PER HOUR ACROSS SOUTHERN WHITLEY COUNTY.

RADAR INDICATES THAT OVER 3 INCHES OF RAIN HAS FALLEN BETWEEN 12:30
AND 2 AM ALONG A LINE FROM LOT...TO RED ASH...TO ZION HILL IN 
SOUTHERN WHITLEY COUNTY. THUNDERSTORMS WILL RAIN THEMSELVES OUT 
ACROSS THE AREA BETWEEN 2 AND 3 AM THIS MORNING...WITH UP TO AN 
ADDITIONAL 2 INCHES OF RAIN POSSIBLE ACROSS SOUTHERN WHITLEY COUNTY.

EXCESSIVE RUNOFF FROM HEAVY RAINFALL WILL CONTINUE TO CAUSE FLOODING 
OF SMALL CREEKS AND STREAMS...HIGHWAYS AND UNDERPASSES. 
ADDITIONALLY...COUNTRY ROADS AND FARMLANDS ALONG THE BANKS OF 
CREEKS...STREAMS AND OTHER LOW LYING AREAS ARE SUBJECT TO FLOODING.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE
DANGERS OF FLOODING. IF FLASH FLOODING IS OBSERVED ACT QUICKLY. MOVE
UP TO HIGHER GROUND TO ESCAPE FLOOD WATERS. DO NOT STAY IN AREAS
SUBJECT TO FLOODING WHEN WATER BEGINS RISING.

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. VEHICLES CAUGHT IN RISING WATER SHOULD BE ABANDONED QUICKLY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
1010 PM EDT THU JUL 21 2005

.DISCUSSION...

AT 1000 PM EDT...THE DOPPLER RADAR SHOWED THE ONLY REMAINING
THUNDERSTORMS AND SHOWERS WERE OVER MCCREARY COUNTY. BY 1025 PM
EDT...MOST OF THE ACTIVITY SHOULD BE OVER. IT IS STILL MOIST ENOUGH
FOR A SMALL SHOWER TO POP UP THIS EVENING...HOWEVER THEY SHOULD BE
VERY WIDESPREAD. THE BIG QUESTION IS THE TIMING FOR THE NEXT
SHORTWAVE TO MOVE THROUGH THE AREA. THE GFS IS A LITTLE FASTER WITH
THE SHORT WAVE THAN THE NAM. BOTH SOLUTIONS WOULD RESULT IN
CONTINUED AFTERNOON CONVECTION...HOWEVER THE NAM SOLUTION WOULD
RESULT IN HIGHER POPS BECAUSE THE SHORT WAVE WILL BE MOVING THROUGH
DURING PEAK CONVECTION HOURS.  THIS SYSTEM MAY BE ABLE TO POP A
COUPLE OF SEVERE STORMS...ESPECIALLY IF THE SLOWER NAM SOLUTION
VERIFIES. THE SEVERE ACTIVITY WOULD BE LIMITED TO A MARGINAL WIND
EVENT ASSOCIATED WITH A WET MICROBURST. THE FREEZING LEVEL IS JUST
TOO HIGH TO PRODUCE ANY SIGNIFICANT HAIL. THE FORECAST IS A BLENDED
SOLUTION...LEANING MORE TOWARD THE GFS. THE ALMOST UNBEARABLE HEAT
WILL CONTINUE THROUGH THE NEXT FEW DAYS AS THE BERMUDA HIGH WILL
REMAIN IN PLACE. THE FORECAST WAS UPDATED FOR POP TONIGHT AND
TOMORROW AND TO DECREASE THE WINDS FOR TONIGHT.

.PREV DISCUSSION...

457 PM EDT THU JUL 21 2005

.DISCUSSION...

RADAR SHOWS RAPID DEVELOPMENT OF SHOWERS AND THUNDERSTORMS OCCURRING
ACROSS FORECAST AREA...PRIMARILY IN WESTERN ZONES. ENHANCED ACTIVITY
ATTRIBUTABLE TO VORTICITY LOBE...WHICH BEGAN DIGGING OUT OF SOUTHERN
INDIANA EARLY THIS MORNING. THIS FEATURE WAS QUITE NOTICEABLE ON
BOTH WATER VAPOR AND VISIBLE IMAGERY EARLIER TODAY. SHOWERS SHOULD
CONTINUING TRACKING WITH LOBE ACROSS REGION THROUGH EARLY EVENING.
EXPECT ACTIVITY TO BE LONGER LIVED AND MORE WIDESPREAD THAN THE LAST
COUPLE OF EVENINGS.

BIGGEST CHALLENGE IN THE NEAR TERM FORECAST IS POPS AND WEATHER
ASSOCIATED WITH UPSTREAM VORT LOBE WHICH IS PROGGED INTO THE OHIO
VALLEY OVERNIGHT. 12Z MESO-NAM SHOWS DECENT UVV EARLY MORNING. POPS
WERE INCREASED GRADUALLY OVERNIGHT...AS SHOWER AND THUNDERSTORM
LIKELIHOOD WILL INCREASE AS IMPULSE MOVES THROUGH THE AREA. BULK OF
ENERGY APPEARS LIKE IT WILL BE IN OUR NORTHERN ZONES...THOUGH SOME
ACTIVITY IS POSSIBLE THE ENTIRE CWA. PRECIPITABLE WATER VALUES WILL
BE 1.75 TO 2 INCHES...SO HEAVY RAIN REMAINS POSSIBLE WITH SOME OF
THE MORE INTENSE STORMS. TIMING OF PRECIPITATION MAY NEED
ADJUSTING...AS THE 18Z NAM IS SLOWER THAN THE PREVIOUS RUN...
INDICATING THE BIGGEST THREAT IS LATER FRIDAY MORNING.

5H RIDGE BEGINS BUILDING INTO THE COMMONWEALTH LATE FRIDAY EVENING
AND IS THE DOMINATING FEATURE AS WE MOVE INTO THE WEEKEND.

MINIMUM AND MAXIMUM TEMPERATURES WERE ONLY ADJUSTED SLIGHTLY FROM
THE EARLIER FORECAST PACKAGE. STAYED CLOSE TO FWC MOS GUIDANCE...
WITH ABOVE NORMAL READINGS EXPECTED BOTH FRIDAY AND SATURDAY. WITH
WARM TEMPERATURES AND HIGH DEWPOINTS...HEAT INDICES WILL MOVE INTO
THE 90S FOR BOTH SATURDAY AND SUNDAY.

EXTENDED (FOR THE PERIOD SUNDAY THROUGH THURSDAY)...

UPPER HIGH WILL DRIFT EAST OVER THE AREA FOR SUNDAY AND MONDAY. THIS
SHOULD PREVENT PRECIP. ASSUMING PLENTIFUL SUNSHINE...850 MB TEMPS
(22-23C) SUPPORT POTENTIALLY THE WARMEST SURFACE TEMPS OF THE
SEASON SO FAR. HAVE PLAYED IT AS LOWER TO MID 90S FOR MOST
LOCATIONS.

GFS AND ECMWF BOTH SHOW THE HIGH GIVING WAY TO A TROUGH MOVING
SOUTHEAST TOWARD THE GREAT LAKES AND NEW ENGLAND DURING THE MID AND
LATE PORTION OF THE WEEK. THIS WILL ALLOW A SURFACE COLD FRONT TO
HEAD SOUTHEAST INTO THE AREA. THE GFS HAS TRENDED SLOWER SINCE
YESTERDAY...AND THE SLOWER MOVEMENT IS SUPPORTED BY THE ECMWF. HAVE
PLACED THE HIGHEST POPS AS THE FRONT APPROACHES LATE WEDNESDAY INTO
WEDNESDAY EVENING...AND TAPERING OFF AFTER THAT. HOWEVER...IF THE
TREND FOR A SLOWER PASSAGE CONTINUES...IT IS CONCEIVABLE THAT HIGHER
POPS COULD END UP HOLDING ON EVEN LATER IN THE WEEK.

1050 AM EDT THU JUL 21 2005

14Z SFC ANALYSIS SHOWS BROAD...THOUGH WEAK...HIGH PRESSURE OVER THE
SOUTHEAST WITH STAGNANT LOW PRESSURE THROUGH THE MIDWEST. ON
SATELLITE...A LARGE MCS IS PLOWING THROUGH WISCONSIN WITH A DECENT
OUTFLOW BLOWING SOUTHEAST INTO CENTRAL ILLINOIS. CLOSER TO HOME...
REMAINS OF AN EARLIER MCS IN OHIO WILL BE SPREADING CLOUDS AND SOME
WEAK OUTFLOW BOUNDARIES INTO EAST KENTUCKY LATER TODAY. THESE
COMBINED WITH THE HEAT OF THE DAY...JUICY DEWPOINTS...AND HIGH
INSTABILITY SHOULD ENABLE SHOWERS AND THUNDERSTORMS TO DEVELOP
DURING THE EARLY AFTERNOON. THE FORECAST HAS MUCH OF THIS IN HAND...
WILL BE UPDATING THE TEXT ZONES TO REMOVE THE MORNING WORDING. HAVE
ALSO UPDATED THE GRIDS TO FINE TUNE THE SKY COVER AND POP FIELDS.
UPDATES TO THE NDFD AND WEB ALREADY ISSUED WITH TEXT ZONES TO FOLLOW
SHORTLY.

414 AM EDT THU JUL 21 2005

BOTH THE NAM AND GFS MODELS ARE IN GOOD AGREEMENT UNTIL DAY 3 WHEN
BOTH MODELS DIVERGE GREATLY IN HOW THEY MOVE A COLD FRONT ACROSS THE
NORTH CENTRAL UNITED STATES. DUE TO THIS DIFFERENCE...DECIDED TO
ONCE AGAIN GO WITH THE GFS FOR SHORT TERM PORTION OF FORECAST.
TEMPERATURES LOOKED PRETTY GOOD...BUT WILL REEVALUATE ONCE NEW FWC
AND MAV MOS RUNS COME IN TO SEE IF ADJUSTMENTS NEED TO BE MADE.
PERSISTENCE LOOKS LIKE IT WILL PAY OFF ONCE AGAIN. LATEST WATER
VAPOR IMAGERY SHOWING A WEAK SHORTWAVE MOVING EASTWARD OUT OF THE
SOUTHERN PLAINS. THIS FEATURE IS SANDWICHED BETWEEN A STATIONARY
FRONTAL BOUNDARY DRAPED ACROSS THE OHIO VALLEY...AND THE WESTERN
EDGE OF RIDGE IN PLACE OVER THE SOUTHEASTERN UNITED STATES.

MODEL SOUNDINGS AND CROSS SECTIONS STILL HAVE AMPLE LOW LEVEL
MOISTURE IN PLACE...THERE SHOULD BE ENOUGH LIFT ALONG THE OHIO
VALLEY FRONTAL SURFACE FOR AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS TO FORM THURSDAY AFTERNOON...ESPECIALLY AS THE
SHORTWAVE MOVES IN FROM THE PLAINS. BOTH GFS AND NAM MODELS ARE
STILL TRYING TO BRING AN MCS ACROSS THE OHIO VALLEY AND INTO EASTERN
KENTUCKY THURSDAY NIGHT INTO FRIDAY MORNING. WITH MODELS SHOWING
THIS PATTERN 3 DAYS IN A ROW...WILL CONTINUE TO GO WITH IT FOR NOW.
DEWPOINTS AND WINDS LOOK GOOD...ONLY MINOR CHANGES AT BEST WILL BE
MADE. ALL MODELS HAVE HIGH PRESSURE BUILDING ACROSS THE REGION FOR
THE WEEKEND. WITH VERY WARM 850HPA TEMPERATURES AND STRONG RIDGING
IN PLACE...ANTICIPATE ABOVE NORMAL TEMPERATURES FOR THE
WEEKEND...WITH CLEAR SKIES AND LIGHT WINDS.

925 PM EDT WED JUL 20 2005

SHOWERS AND THUNDERSTORMS ARE WINDING DOWN WITH LOSS OF DAY TIME
HEATING. CAN NOT RULE OUT AN ISOLATED SHOWER OR THUNDERSTORM
OVERNIGHT. ALSO EXPECT PATCHY DENSE FOG WILL BECOME A PROBLEM...
ESPECIALLY WHERE THE HEAVIEST RAIN HAS FALLEN. CURRENT FORECAST HAS
ALL OF THIS COVERED WELL. ISC GRID ELEMENTS ARE IN GREAT SHAPE...
EVEN HOURLY TEMPS AND DEW POINTS ARE ON TARGET. ONLY UPDATE TONIGHT
WILL BE FOR MIDNIGHT WORDING. SO WILL GO WITH A LATE UPDATE...TO BE
ISSUED A LITTLE LATER TONIGHT.
