AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 222 PM MDT (322 PM CDT) SAT JUN 14 1997 CHANCES FOR RAIN EACH PERIOD MAIN CONCERN FOR THIS PACKAGE. MODELS ARE RATHER SIMILAR...BUT MINOR DIFFS CREATE HAVOC WITH TIMING OF PRECIP AND LOCATION OF FRONT ON SUNDAY. HAVE LEANED TO AVN BASED ON SLIGHTLY BETTER H70 THERMAL INITIALIZATION AND 6-HOUR SURFACE PRESSURE VERIFICIATION. THUS QUESTION BECOMES WHERE AND WHEN WILL PRECIP FALL. LOOKS LIKE COLORADO COUNTIES UNDER THE GUN FOR SEVERE AFTER 00 UTC...BUT WITH LOSS OF HEATING SEVERITY PROBABILITY SHOULD DROP OFF DRAMATICALLY. SOME STORMS MAY WORK INTO NORTHWEST KANSAS AND SOUTHWEST NEBRASKA...BUT BETTER DYNAMICS SHOW UP SUNDAY BEHIND FROPA. WILL BLEND FAN AND FWC POPS AND LEAN TO FAN TEMPS.
