AREA FORECAST DISCUSSION...CORRECTED NAME
NATIONAL WEATHER SERVICE GOODLAND KS
243 PM MDT WED MAY 17 2000

MAIN FORECAST CHALLENGES FOR THIS PACKAGE ARE CHANCES FOR
PRECIPITATION TONIGHT AND TOMORROW AND COOLER AIR MOVING IN THROUGH
3RD PERIOD.

ALL MODELS INITIALIZING WELL. THE ETA SEEMS TO BE DOING A SLIGHTLY
BETTER JOB AT TRACKING LOW OVER REGION OUT TO 18Z. FOR ALL INTENSIVE
PURPOSES FOR MY CWA THERE IS NOT MUCH DIFFERENCES IN THE TRACK OF
THIS SYSTEM FOR THE FIRST FOUR PERIODS...EXCEPTIONS WILL BE NOTED
BELOW. BUT WITH THE CONSISTENT GOOD HANDLING OF THIS SYSTEM BY THE
ETA...WILL CONTINUE THIS TREND FOR THIS PACKAGE.

TONIGHT AND TOMORROW...WILL ADJUST ETA QPF FIELD FOR DRY LINE
EXTENDING THROUGH EASTERN PART OF CWA. WILL CUT BACK SLIGHTLY ON
POPS FOR SE PORTIONS. 18Z ETA HAS MODIFIED H85 TEMPS
SUBSTANTIALLY...AND THIS SEEMS TO TAKE THE DRY LINE AND WARMER AIR
WRAPPING AROUND AND MIXING INTO THIS AIRMASS.

THURSDAY NIGHT AND FRIDAY ETA H85 TEMPS SUPPORT GOING SLIGHTLY ABOVE
FWC HIGHS AND WILL ADJUST IN THAT DIRECTION.

IN THE EXTENDED...MODELS DIVERGE GREATLY AND THEREFORE DO NOT HAVE A
GREAT CONFIDENCE LEVEL FOR PORTION. FEEL AT THIS TIME THAT THE ECMWF
SOLUTION IS MORE FAVORABLE AND HAVE LEANED IN THIS DIRECTION.

.GLD...TORNADO WATCH IN EFFECT UNTIL 7 PM MDT (8 PM CDT) FOR NE ZONES
       079-081.
       TORNADO WATCH IN EFFECT UNTIL 9 PM CDT FOR KS ZONES 004 AND
