Area forecast discussion, May 12, 2:55 PM CDT, 7 hours 47 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 255 PM CDT FRI MAY 12 2000 MAIN FORECAST CHALLENGE CONTINUES TO BE TIMING OF PRECIPITATION. AFTER THAT...THE WEEKEND WEATHER LOOKS FAIRLY STRAIGHTFORWARD. LATEST 19Z SURFACE ANALYSIS DEPICTS LOW PRESSURE OVER THE GREAT LAKES WITH A COLD FRONT STRETCHING SOUTHWEST INTO SOUTHWEST MISSOURI AND OKLAHOMA. VISIBLE SATELLITE AND 88D LOOPS CLEARLY DEFINE THE FRONT ALONG THIS LINE...WHERE THUNDERSTORMS ARE BEGINNING TO BREAK OUT. MORNING UPPER-AIR ANALYSIS DEPICTED AN H5 TROUGH OVER THE MIDDLE UNITED STATES EXTENDING FROM A LOW OVER NORTH DAKOTA. AN H5 70 KNOT JET MAX WAS ANALYZED OVER THE NORTHERN PLAINS AND UPPER MIDWEST... WHILE AN H8 50 KNOT JET MAX STRETCHED ACROSS OKLAHOMA INTO SOUTHWEST MISSOURI. PROMINENT AT ALL LEVELS UP THROUGH 500 MB WAS AN AXIS OF WARM...DRY AIR SERVING TO CAP THUNDERSTORM DEVELOPMENT THIS MORNING ACROSS THE FORECAST AREA...WITH A CLASSIC LOADED-GUN APPEARANCE ON SOUNDINGS. SURFACE-BASED INSTABILITY VALUES ALL POINT TOWARD AN INCREASINGLY UNSTABLE ATMOSPHERE THROUGH THE EVENING HOURS...ESPECIALLY OVER SOUTHERN ILLINOIS AND SOUTHEAST MISSOURI. IN FACT...MSAS SURFACE COMPUTED LI/S ARE ALREADY -9 FROM CHICAGO TO ST. LOUIS INTO SOUTHERN MISSOURI. THIS AXIS OF GREATER INSTABILITY IS EXPECTED TO SHIFT EAST ACROSS THE FORECAST AREA TONIGHT RIGHT IN ADVANCE OF THE COLD FRONT. EVEN THOUGH THE BEST DYNAMICS WILL BE TO OUR NORTH...THERMODYNAMICS FAVOR THE POTENTIAL OF SEVERE STORMS TONIGHT...ESPECIALLY WHERE SPC/S MODERATE RISK IS OUTLINED OVER PARTS OF SOUTHERN ILLINOIS AND ADJACENT AREAS. WILL USE "LIKELY...MAINLY THIS EVENING" WORDING OVER NORTHWEST 2/3 OF FORECAST AREA...WITH CHANCE POPS ALL NIGHT ELSEWHERE. WILL ALSO MENTION POTENTIAL FOR SEVERE STORMS...STRESSING GREATER POTENTIAL IN THE MODERATE RISK AREA. AS FRONT DEPARTS FROM THE AREA ON SATURDAY...COULD BE SOME LINGERING EARLY MORNING CLOUDS MAINLY SOUTHEAST OF THE OHIO RIVER...BUT BELIEVE THAT MOST OF THE REGION WILL SEE PLENTY OF SUNSHINE AS HIGH PRESSURE BUILDS IN. TEMPERATURES WILL LIKELY STRUGGLE THROUGH THE 70S ON SATURDAY IN STRONG NORTHWEST FLOW...SO WILL USE MIDDLE TO UPPER 70S FROM NORTHWEST TO SOUTHEAST. REST OF WEEKEND LOOKS DRY UNDER MOSTLY CLEAR SKIES. WILL GENERALLY TREND TOWARD WARMER FWC NUMBERS DURING THE DAY AND COOLER FAN NUMBERS AT NIGHT. NEXT CHANCE OF SHOWERS AND THUNDERSTORMS APPEARS TO BE TUESDAY AND WEDNESDAY IN ADVANCE OF THE NEXT SYSTEM. .PAH...NONE PRESLEY
