AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 300 AM CDT FRI APR 7 2000 SFC MAP AT 07Z SHOWING WARM FRONT ACROSS THE NRN TIER OF THE FA EXTENDING FROM KEVV-KMVN. SHRA/TSRA ACTIVITY FIRING NORTH OF THIS BOUNDARY AT THE NOSE OF H8 THETA-E RIDGE IN AXIS OF BEST UPGLIDE ON I300K SFC. MOST OF THIS PCPN SHOULD REMAIN NORTH OF THE FA AS WARM FRONT DRIFTS SLOWLY NORTHWARD THIS MORNING. MAIN FCST CONCERNS CENTERING AROUND POPS AND WINDS IN THE FIRST 2 PERIODS. WILL USE A BLENDED NGM/ETA SOLUTION...AS THE AVN APPEARS TO BE TOO FAST WITH THE SFC FEATURES. SFC LOW OVER WRN NEBRASKA WILL PUSH E/SE TODAY...PASSING JUST NORTH OF KSTL SHORTLY AFTER 18Z AND TOWARD THE WABASH RIVER VALLEY BY 00Z. THIS WILL BRING A PRE-FRONTAL TROF/DRY LINE ACROSS MISSOURI THIS AFTN AND TOWARD THE MS RIVER BY 00Z. LOW LEVEL MOISTURE SHOULD STREAM NORTHWARD IN ADVANCE OF THIS FEATURE...WITH ARND 60 DEGF DWPTS SURGING ACROSS THE FA. GOOD CONVERGENCE ALONG THE TROF/DRY LINE...WITH UVM FIELDS FURTHER ENHANCED BY CORE OF MID/UPR LEVEL DIVERGENCE PUSHING ACROSS IL/IN THIS AFTN. SCATTERED ACTIVITY ALONG THE PRE-FRONTAL FEATURE EARLY THIS AFTN OVER MO SHOULD GRADUALLY DEVELOP INTO A SQUALL LINE AS THE TROF PUSHES EAST INTO THE FA. WITH SHEAR PROFILES QUITE IMPRESSIVE AND SBCAPES OF 1500-2000 J/KG...AT LEAST SCT SEVERE ACTIVITY (SUPERCELLS?) APPEARS LIKELY AND WILL KEEP WORDING IN THE ZONE. SQUALL LINE EXITS ERN PARTS OF THE FA THIS EVENING WITH COLD FROPA SHORTLY THEREAFTER. WITH THE SFC LOW INTENSIFYING LATER TODAY AND TONIGHT RESULTING IN A TIGHTENING PRESSURE GRADIENT...WILL INCREASE WINDS TO WINDY CATEGORY TONIGHT. FCST SOUNDINGS AND H10-H8 TEMP ANALYSIS WOULD POINT TOWARD THE POSSIBILITY OF A CHANGEOVER TO LIGHT SNOW/FLURRIES OVERNIGHT IN NRN ZONES AS WRAP-AROUND MOISTURE MOVES ACROSS THE REGION. WITH MOST OF THE FORCING EAST OF THE FA BY 06Z...ANY LEFT OVER PCPN SHOULD BE QUITE LIGHT AND SCATTERED. WILL LEAVE A LOW POP IN NE ZONES ON SATURDAY AS WRAP-AROUND LOW LEVEL MOISTURE AND STRONG CAA COULD STILL SQUEEZE OUT SOME SPOTTY --RA/SN. GOOD DRYING OVER WRN ZONES BY AFTN SHOULD RESULT IN DECREASING CLOUDINESS...WITH MORE PESSIMISTIC MOSTLY CLOUDY OVER ERN AREAS. FWC/FAN NOS IN FAIRLY GOOD AGREEMENT. WILL CUT NOS DOWN A CATEGORY ON SATURDAY GIVEN THE STRONG CAA. WILL LIKELY NEED ANOTHER FROST ADVISORY SATURDAY NIGHT AS WINDS GO LIGHT AND TEMPS DROP INTO THE UPR 20S/LWR 30S. .PAH...NONE. JK

ON THE MIDDAY WEATHER MAP...A WARM FRONT EXTENDED EASTWARD FROM NW MISSOURI ACROSS CENTRAL ILLINOIS AND SOUTHERN INDIANA. SHOWERS AND THUNDERSTORMS WERE DEVELOPING ACROSS PORTIONS OF SOUTHERN ILLINOIS AND SOUTHEAST MISSOURI ALONG AN OUTFLOW BOUNDARY LAID DOWN BY EARLIER CONVECTION TO THE NORTH. AN AREA OF LOW PRESSURE OVER NORTHWEST MISSOURI WILL STRENGTHEN AS IT MOVES TO WEST CENTRAL INDIANA BY LATE AFTERNOON. THE LOW WILL DRAG A STRONG COLD FRONT ACROSS THE REGION DURING THE AFTERNOON AND EVENING HOURS. AHEAD OF THE COLD FRONT...STRENGTHENING SOUTHWEST WINDS WILL USHER WARM AND MOIST AIR INTO THE QUAD STATE REGION. BREAKS IN THE CLOUDS AND THE SOUTHWEST WINDS WILL ALLOW TEMPERATURES TO WARM INTO THE LOWER 70S. THE COMBINATION OF THESE WARM TEMPERATURES AND INCREASING MOISTURE WILL RESULT IN THE AIRMASS BECOMING MODERATELY UNSTABLE THIS AFTERNOON. SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP ACROSS THE REGION. AS THE COLD FRONT APPROACHES THE REGION FROM THE WEST... THESE STORMS SHOULD THEN BEGIN TO ORGANIZE INTO A SQUALL LINE BY LATE THIS AFTERNOON ACROSS PORTIONS OF SOUTHERN ILLINOIS AND SOUTHEAST MISSOURI. THIS SQUALL LINE SHOULD THEN MOVE EAST ACROSS WESTERN KENTUCKY AND SOUTHWEST INDIANA BY THE LATE EVENING HOURS. VERTICAL WIND PROFILES SUGGEST THAT A FEW OF THE STORMS THIS AFTERNOON MAY BECOME SUPERCELLS. TORNADOES ARE POSSIBLE WITH THE SUPERCELLS ALONG WITH DAMAGING WINDS AND LARGE HAIL. AS THE STORMS DEVELOP INTO THE SQUALL LINE...THE MAIN SEVERE THREAT SHOULD BE DAMAGING WINDS AND HAIL. THE THREAT OF SEVERE WEATHER WILL END WITH THE PASSAGE OF THE STRONG COLD FRONT. THE FRONT WILL MOVE EAST OF THE QUAD STATE REGION BY MIDNIGHT. STORM MOVEMENT IS EXPECTED TO BE TO THE NORTHEAST AT 40 TO 45 MPH. SPOTTER ACTIVATION WILL LIKELY BE NEEDED THIS AFTERNOON AND EVENING.
