Area forecast discussion, Jul 7, 2:35 PM CDT, 4 hours 6 minutes before
CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 235 PM CDT MON JUL 7 1997 CHANCES OF TRW TONIGHT AND TIMING OF FRONT PRIMARY CONCERNS TAFTN. 18Z SFC ANAL SHOWED A LOW IN SW NEB/NW KS WITH A STRONG MOIST SLY FLOW INTO THE CWA. I PLACED THE WARM FRONT MUCH FURTHER TO THE NORTH THAN THE 90F CLOSER TO THE 60 DEW POINT LINE WHICH ALSO LINED UP BETTER WITH THE LOW LEVEL CONVERGENCE. THE COLD FRONT WAS LOCATED FROM THE WRN DAKOTAS SOUTH INTO THE LOW. ALOFT SIG 7H S/W MOVG THRU THE AREA THIS MORNING AND PLENTY OF 8H MOISTURE. MODELS CONTINUE TO BUILD A WEAK RIDGE OVER TIME TO THE NORTH OF THE AREA AND ARE IN FAIRLY GOOD AGREEMENT. LOOKS LIKE THE FRONT SHOULD PUSH THRU THE NEB CWA BY EARLY TOMRROW MORNING AND THE KS CWA LATER IN THE DAY IF AT ALL. FRONT MAY STALL OUT IN KS AND IS WHY QPFS CONTINUE INTO WED AS THERE WILL CONTINUE TO BE A STRONG SOUTHERLY FLOW INTO THE FRONT. FOR TONIGHT AIRMASS CONTINUES TO BECOME MORE UNSTABLE WITH AFTN HEATNG. CAPES FROM MODELS INDICATE WELL OVER 3000 AND VEERING WINDS FROM THE VAD WIND PROFILERS. APPEARS TO ME THE BEST CHANCE OF SVR WX TONIGHT SHOULD BE AHEAD OF THE WARM FRONT IN SRN MN/NRN IA BUT THE CWA WILL PROBABLY HAVE A GOOD CHANCE OF SOME STORMS. IF FRONT DOES STALL OUT THEN WE SHOULD PROBABLY KEEP SOME MENTION OF PRECIPITAION GOING IN THE FORECAST.
