NATIONAL WEATHER SERVICE HASTINGS NE
220 PM CDT TUE JUN 23 1998

...CHANCE OF THUNDERSTORMS TONIGHT AND TEMPERATURES THROUGH THE FORECAST
ARE PROBLEMS THIS AFTERNOON...

18Z SFC CHART SHOWED LOW IN NE COLO/NW KS WITH WARM FRONT LAYING ALONG
THE KS/NE BORDER.  65+ DEW POINTS ARE POOLED FROM NRN KS INTO CENTRAL
NEB AND INTO ERN SD.  UAA THIS MORNING SHOWED SEVERAL S/WS IN A SW FLOW.
MAIN WAVE TO EFFECT CWA THIS EVENING IS SEEN ON WATER VAPOR IMAGERY
MOVING ACROSS ERN COLO. PROFILER DATA SHOWING SOME VEERING ESPECIALLY IN
ERN NEB.  3H ANAL SHOWED JET COMING OUT OF THE DESERT SW THIS MORNING
AND THIS TOO SHOULD HELP IN THE DEVELOPMENT OF TRW.

OMEGA FIELDS ESPECIALLY ON ETA/AVN ARE IMPRESSIVE...9 MICROBARS...THIS
EVENING IN THE CWA.

LAPS DATA SHOWING CAPES OF 2-3K OVER THE CWA AT 18Z WITH SFC WIND
STREAMLINES SHOWING CONVERGENT FLOW IN THE SW PTN OF THE CWA. THIS COULD
BE AN AREA TO WATCH FOR INITIAL DEVELOPMENT.

NOT SURE EXACTLY WHERE TRW WILL FIRE THIS EVENING BUT AM CONFIDENT THERE
WILL BE SOME ACTIVITY.  RIGHT NOW FEEL NEB CWA MAY BE MORE UNDER THE GUN
THAN KS AREA.

850 TEMPS ON ALL MODELS WARM OVER THE NEXT COUPLE OF DAYS SO EXPECT TO
BE VERY WARM.  READINGS OVER THE CENTURY MARK ESPECIALLY IN KS SHOULD BE
COMMON.  700 TEMPS ALSO WARM SO BY TOMORROW WE SHOULD SEE FAIRLY GOOD
CAPPING.
