AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 140 PM MDT THU JUN 19 2003 TONIGHT...COPIOUS DEEP MOISTURE/SHORTWAVE TROUGH MOVING THRU THE AREA SUGGEST HIGH RAIN CHANCES TONIGHT...GREATEST ACROSS THE EAST WHERE UPWARD VERTICAL MOTION WILL BE STRONGEST. WILL RANGE PROBABILITY OF PRECIPITATION FROM 70 PERCENT WEST TO 90 PERCENT EAST. HEAVY RAINERS A GOOD BET BASED ON WEAK STEERING FLOW. FRI...WILL SEE LEFTOVER PRECIPITATION ACROSS THE EASTERN ZONES IN THE MORNING. SHARP NORTH-SOUTH ORIENTED THETA-E RIDGE AXIS EXTENDS ACROSS THE ZONES WHILE A STRONG LOW LEVEL THERMAL RIDGE AXIS AND SURFACE TROUGH COINCIDE ACROSS EASTERN CO. WIND SHEAR AND CONVECTIVE AVAILABLE POTENTIAL ENERGY (CAPE) PARAMETERS SUGGEST SCATTERED THUNDERSTORMS...SOME SEVERE...IN THE AFTERNOON ACROSS THE EASTERN CO ZONES. FRI NIGHT...SCATTERED THUNDERSTORMS EXPECTED TO PROGRESS EASTWARD ACROSS THE ZONES AS BOUNDARY MOVES ACROSS. SHOULD SEE SOME SEVERE THUNDERSTORMS...PRIMARILY IN THE EVENING...DUE TO ADEQUATE WIND SHEAR AND CAPE. SAT...FLOW ALOFT TURNS ZONAL WITH DRIER AIR INVADING THE REGION. SMALL THREAT OF THUNDERSTORMS IN THE AFTERNOON ACROSS THE EASTERN ZONES WHERE THETA-E RIDGE AXIS AND SURFACE TROUGH RESIDE. HOWEVER... WILL LEAVE OUT THUNDERSTORMS AS LOW LEVEL CONVERGENCE LOOKS TOO MEAGER AND CAP WILL LIKELY BE STRONG. ETA MOS HIGHS LOOK CLOSEST BASED ON 850 MB TEMPERATURES NEAR 28C. SUN...SOUTHWEST FLOW ALOFT PREVAILS WITH LOW LEVEL UPSLOPE LIKELY CONFINING THUNDERSTORMS TO THE COLORADO FRONT RANGE. MON/TUE...DRY SOUTHWEST FLOW CONTINUES. WITH 850 MB TEMPERATURES NEAR 28-30C AND BONE DRY ATMOSPHERE...GFS HIGHS LOOK TOO COLD BY 5-10 DEGREES. WED...IF GFS IS CORRECT WITH ITS PROGRESSION OF A SHORTWAVE TROUGH ACROSS THE NORTHERN ROCKIES AND A BOUNDARY IN THE AREA...THUNDERSTORMS A GOOD BET. GFS HIGHS STILL TOO COLD BASED ON 850 MB TEMPERATURES. THU...GFS LIKELY COOLING MAXIMA TOO MUCH AS IS ITS TENDENCY AND WILL STICK WITH HIGHS CLOSE TO CLIMATOLOGY.

COZ090>092-KSZ001>004-013>016-027>029-041-042-NEZ079>081-201100- HAZARDOUS WEATHER OUTLOOK NATIONAL WEATHER SERVICE GOODLAND KS 943 AM MDT THU JUN 19 2003 THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST KANSAS...EXTREME SOUTHWEST NEBRASKA...AND EAST CENTRAL COLORADO. .DAY ONE...TODAY AND TONIGHT THE AIR MASS CONTINUES TO REMAIN MOIST AND SOMEWHAT UNSTABLE. A SLOW MOVING UPPER LEVEL STORM WILL ACT ON THIS AIR MASS...AND PRODUCE SCATTERED TO NUMEROUS THUNDERSTORMS ACROSS THE ENTIRE AREA. DUE TO THE VERY MOIST AIR MASS IN PLACE AND THE EXPECTED SLOW MOVEMENT OF THE STORMS THAT DEVELOP...LOCALLY HEAVY RAINFALL WILL ONCE AGAIN BE THE MAIN THREAT. RAINFALL RATES COULD REACH 1 TO 2 INCHES PER HOUR DUE TO THE SPOTTY AND ISOLATED NATURE OF THE HEAVY RAINFALL. REPORTS OF HEAVY RAINFALL AND ANY FLOODING WOULD BE GREATLY APPRECIATED. THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY BY FRIDAY...A SURFACE TROUGH OVER EASTERN COLORADO WILL INCREASE IN STRENGTH...AND PRODUCE BREEZY TO WINDY CONDITIONS THROUGH FRIDAY NIGHT. THIS WILL CAUSE THE AIR MASS TO BECOME EVEN MORE UNSTABLE...AND PRODUCE A STRONG DRYLINE NEAR THE KANSAS AND COLORADO BORDER. THESE FACTORS COMBINED WITH A WEAK UPPER LEVEL STORM SYSTEM WILL PRODUCE SCATTERED THUNDERSTORMS ACROSS MOST OF THE AREA. AFTER A DRY SATURDAY AND SUNDAY...THE NEXT CHANCE FOR THUNDERSTORMS WILL BE ON MONDAY AND TUESDAY. THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT ANTICIPATED FOR TODAY AND TONIGHT. BULLER/SMITH
