Area forecast discussion, Jun 18, 5:30 AM CDT, 1 hour 31 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 530 AM CDT SAT JUN 18 2011 .DISCUSSION... DELAYED DISCUSSION THIS MORNING DUE TO ACTIVE WEATHER. MAIN CHALLENGE FOR THE NEXT 48 HOURS WILL BE DEFINING THE SPATIAL AND TEMPORAL ASPECTS OF THE TRAIN OF MCS /MESOSCALE CONVECTIVE SYSTEMS/ MOVING ALONG THE MEAN FRONTAL BOUNDARIES ORIENTED OVER THE WFO PAH FORECAST AREA. THE 00Z AND 06Z SATURDAY DETERMINISTIC GFS AND 21Z FRIDAY/03Z SATURDAY SREF GUIDANCE HAVE A GENERALIZED SOLUTION ON THE ORIENTATION/TIMING OF THESE SYSTEMS AND WAS UTILIZED IN MODIFYING THE POP/WX/QPF FORECAST FOR TODAY AND TONIGHT. THERE REMAINS SOME UNCERTAINTY AS TO THE EFFECTIVE FRONTAL BOUNDARY ZONE /DUE TO RAIN INDUCED COLD POOLS/ OVER THE NORTHERN 1/3 OF THE WFO PAH FORECAST AREA FOR SUNDAY. AT THIS TIME...THE FORECAST IS DIRECTED TOWARD MORE CAPPING OF THE ATMOSPHERE FOR MOST OF THE WFO PAH FORECAST AREA...WITH THE POSSIBLE EXCEPTION OF THE INTERSTATE 64 CORRIDOR IN SOUTHERN IL AND SOUTHWEST IN. THIS IS SOMEWHAT AT ODDS WITH THE SPC DAY TWO OUTLOOK...BUT THIS JUST MAY BE A MATTER OF TIMING...DEPENDING ON THE POSITION OF THE EXPECTED OVERNIGHT MCS INTO SUNDAY MORNING. ADJUSTED TEMPERATURES DOWNWARD TODAY TO REFLECT THE INFLUENCE OF CLOUD COVER AND ANY EXPECTED PRECIPITATION DURING THE MORNING...WITH SOME CLEARING EXPECTED DURING THE AFTERNOON HOURS. OTHERWISE A DEFAULT 20-22 DEGREE DIURNAL RANGE OF TEMPERATURES CAN BE EXPECTED EARLY IN THE WEEK AS THE UPPER RIDGE BUILDS IN AND INCREASES THICKNESSES OVER THE AREA. && .AVIATION... VFR CONDITIONS WILL LIKELY DOMINATE OUTSIDE OF THE MCS /MESOSCALE CONVECTIVE SYSTEMS/ THAT WILL PUSH ACROSS THE WFO PAH TAF SITES. HOWEVER...A 1-3 HOUR PERIOD OF MVFR/HIGH IFR CEILINGS AND VISIBILITIES WILL BE POSSIBLE WITH THE PASSAGE OF THUNDERSTORM CLUSTERS TODAY AND TONIGHT. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE. IN...NONE. && AVIATION/FIRE WEATHER...CTN/SMITH SHORT/LONG TERM PUBLIC...SMITH
