AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
215 PM CDT WED JUL 25 2001

PRIMARY FORECAST CHALLENGE REMAINS TIMING OF APPROACHING FRONT AND
RESULTANT CHANCE FOR PRECIPITATION. LATEST 18Z SURFACE CHART DEPICTS
A SURFACE COLD FRONT DRAPED ACROSS NORTHERN INDIANA...CENTRAL
ILLINOIS...AND NORTHERN MISSOURI. IN THE UPPER LEVELS...A WEAK HIGH
PRESSURE RIDGE REMAINS IN PLACE OVER THE CENTRAL PLAINS. AS HAS BEEN
THE CASE DURING THE PAST SEVERAL DAYS...SCATTERED SHOWERS AND
THUNDERSTORMS HAVE DEVELOPED IN THE HEAT OF THE DAY ACROSS THE
REGION.

ON THE MODELS...NEW 12Z ETA RUN IS CONSISTENT IN BRINGING THE
SURFACE FRONT ACROSS THE FORECAST AREA LATER THAN THE AVN. GIVEN THE
TIME OF YEAR AND UPPER FLOW CHARACTERISTICS...STILL PREFER SLOWER
ETA REPRESENTATION. THIS WOULD BRING THE COLD FRONT ACROSS THE OHIO
RIVER BY THURSDAY EVENING...WITH A SLOW PROGRESSION TOWARDS THE
TENNESSEE BORDER THURSDAY NIGHT. RELATIVELY WEAK SHEAR AND HIGH
FREEZING LEVELS WILL CURTAIL THE SEVERE POTENTIAL OF THE STORMS
TONIGHT AND THURSDAY. ALTHOUGH THE OCCURRENCE OF AN ISOLATED
DAMAGING WIND EVENT CANNOT BE RULED OUT CONSIDERING THE MODERATE TO
STRONG INSTABILITY IN PLACE. GIVEN THE SOUPY ATMOSPHERE IN PLACE
(70S DEW POINTS/30S K INDICES/PWS NEAR 2 INCHES)...THE PRIMARY
CONCERN WILL BE LOCALLY HEAVY RAIN WITH THE STRONGER STORMS. IN
CONCURRENCE WITH THE 12Z MOS GUIDANCE...WILL GO LIKELY OVER NORTHERN
ZONE GROUP TONIGHT...WITH A 50 POP SOUTH. TOMORROW/S BREAKOUT WILL
BE JUST THE OPPOSITE...WITH THE HIGHER 70 POP OVER SOUTHERN ZONE
GROUP.

AS SOMEWHAT DRIER AIR FILTERS IN LATE THIS WEEK...EXPECT A BRIEF
REPRIEVE FROM THE DAILY THUNDERSTORM ROUTINE...NAMELY FRIDAY AND
FRIDAY NIGHT. AVN AND MRF RUNS BOTH BRING THE FRONT BACK TO THE
NORTH OVER THE WEEKEND. SO WILL MAINTAIN THE CHANCE FOR SHOWERS AND
STORMS SATURDAY AND SUNDAY. THEN A HIGH PRESSURE RIDGE WILL BUILD
OVER THE MID-MISSISSIPPI RIVER VALLEY FOR THE BEGINNING OF NEXT
WEEK. THIS TIME...THE MODELS INDICATE THE ATMOSPHERE WILL BE
CAPPED...THUS LIMITING THE CONVECTIVE POTENTIAL TO ISOLATED AT BEST.

FOR THE FIRST 60 HOURS...WILL FOLLOW ETA SURFACE TE,MPERATURE
FORECAST. THEREAFTER...A BLEND OF MRF MEX/FMR GUIDANCE IS PREFERRED.
