AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 340 PM CDT SUN MAY 24 1998 ...MAIN CONCERN THIS PACKAGE IS CHC OF RAIN FOR TODAY... RADAR SHOWS RAIN NEARLY WIDESPREAD ACROSS THE CWA...BUT CLEARING OUT QUICKLY. ETA MODEL SEEMED TO MATCH THE 06Z SFC MAP FAIRLY WELL...ALTHOUGH IT REALLY DROPS THE LOW DOWN INTO THE HEART OF TX BY THIS AFTN AND EVENING WHILE THE NGM/AVN KEEP IT IN NW TX. THIS SEEMS TO BE THE TREND LATELY WITH THE ETA MODEL. ALOFT...MODELS ARE IN BETTER AGREEMENT. ANOTHER S/W TO MOVE ACROSS KS THIS AFTN AS SEEN IN THE WATER VAPOR IN NE CO...THERES A PRETTY GOOD COLD POOL ALONG WITH IT. AS THE S/W AND COLD POOL MOVE OVER THE AREA...THIS SHOULD HELP STEEPEN LAPSE RATES AND COULD GET A FEW SHOWERS AND TSRA TO DEVELOP JUST ABOUT ANYWHERE TODAY...SO WILL KEEP 30 POPS IN THE FCST FOR TODAY IN CENTRAL SECTIONS WITH HIGHER POPS IN THE SE. UPPER LEVEL RIDGE TO BUILD INTO THE AREA TONIGHT THROUGH TUE...WITH SFC HIGH SETTLING IN BY 12Z TUE. COULD SEE FOG DEVELOP TONIGHT AS WINDS GO LIGHT AND VARIABLE OVER FAIRLY WET GROUND AND MOSTLY CLEAR SKIES. OTHERWISE...IT SHOULD KEEP THINGS QUIET INTO WED.
