Area forecast discussion, Jun 23, 3:25 PM CDT, 5 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 325 PM CDT TUE JUN 23 1998 ...MAIN PROBLEM TONIGHT IS ANY THREAT FOR THUNDERSTORMS AND BEYOND THAT IS THE AMOUNT OF HEAT EXPECTED... SOME WEAK CONVERGENCE NOTED EASTERN KANSAS THIS EVENING BUT WITH INCREASING LOW LEVEL FLOW...FEEL BEST CHANCE FOR PRECIPITATION IS ALONG NORTHERN/NORTHEASTERN BORDER CLOSER TO REAL FRONT. EVEN THERE...FEEL CHCS ARE RATHER REMOTE BUT PRECIPITATION ALREADY IN THE FORECAST THERE AND WILL NOT FLIP/FLOP ON LOW POPS. BEYOND TONIGHT...DON'T SEE MUCH EXCITING BUT A PERSISTENT HOT WINDY PATTERN. TEMPERATURES WARMING TO EXCESSIVE LEVELS AT H7 PER ETA/SPM. THIS SHOULD EFFECTIVELY CAP ANY SFC BASED TSTM ACTIVITY OUR AREA UNTIL EITHER SOME SGFNT SFC BASED BOUNDARY ENTERS THE PICTURE OR SOME FEATURE ALOFT PROVIDES ENOUGH COOLING TO ERODE CAP. NGM MOS SEEMS ABOUT 5 DEGREES TOO COOL ON DAYTIME HIGHS AND MAYBE A FEW DEGREES TOO COOL AT NIGHT. WITH LOW LEVEL JET IN PLACE AT NIGHT...PERHAPS NGM MOS THREE HOURLY TEMPERATURES BETTER INDICATOR OF OVERNIGHT LOWS THAN ASSOCIATED MOS VALUES. WENT THAT DIRECTION IN FORECAST. .TOP...NONE
