Area forecast discussion, Jun 15, 2:21 PM MDT, 4 hours 40 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 221 PM MDT (321 PM CDT) SUN JUN 15 1997 ...THUNDERSTORM CHANCES (OR WILL IT EVER RAIN IN GOODLAND) CONTINUE TO BE MAIN CONCERN... WILL CONTINUE TO LEAN ON AVN GIVEN MY PREFERENCE FOR ITS TREATMENT OF CUTOFF SOUTHWEST U.S. LOWS AND THE CONSISTENCY OF ITS RUNS. GOOD MID LEVEL INSTABILITY OVERNIGHT AS DEPICTED BY H70-H50 TEMP DIFFS AND THETA-E VERTICAL PROFILES. AHEAD OF MAIN TROUGH AXIS MOVING ACROSS EASTERN CWA PERSISTENT LINE OF SHRA WILL EVENTUALLY ERUPT INTO STRONG/SEVERE TSRA...BUT QUESTION IS WHEN. LEFT EXIT REGION OF JET STREAK SHOULD BEGIN ADDED LIFT TO SOUTHWEST END OF SHRA LINE BY 22Z AND WORK NORTHEAST ALONG LINE. BEHIND THE TROUGH MORE CONVECTION OF THE DIURNALLY DRIVEN VARIETY WILL MOVE INTO COLORADO ZONES...BUT PROBLEM WILL BE WHAT HAPPENS WHEN PREFRONTAL TROUGH AHEAD OF COLD FRONT GETS CROSSED BY YET ANOTHER JET STREAK OVERNIGHT. BELIEVE RESULT WILL BE ENHANCEMENT OF ANY SURVIVING SHOWERS...POSSIBLY WITH A TSRA OR TWO SINCE INSTABILITY WILL BE SUFFICIENT TO MAINTAIN UVV ONCE AGEOSTROPHIC JET MOTIONS GETS THINGS GOING. UPSLOPE PERSISTS THROUGH REST OF PERIOD AS PIECES OF OLD SOUTHWEST U.S. LOW EJECT NORTHEAST OVER CWA. WILL KEEP POPS GOING THROUGHOUT FORECAST AS A RESULT. FWC AND FAN NUMBERS ARE SIMILAR THROUGH PERIOD 3. LEANED A LITTLE CLOSER TO FWC NUMBERS FOR TUESDAY MAX GIVEN AVN TENDENCY TO OVERDO UPSLOPE IN THE WARM SEASON.
