NORTHWEST MISSOURI FORECAST DISCUSSION NATIONAL WEATHER SERVICE PLEASANT HILL/KANSAS CITY MO 235 PM CDT WED MAY 7 1997 PRETTY DRAMATIC MOISTURE INCRS SINCE THIS AM...AS WM FRONT HAS LIFTED NEWD. SIGNIFICANT DESTABILIZATION HAS RESULTED...BUT WERE WAITING ON THE LIFT. COLD FRONT TRYING TO INITIATE TSRA ACTIVITY TO OUR W AND NW...WHICH...ONCE IT GETS GOING...SHOULD HAVE NO PROBLEM ROLLING THRU FA IN 22Z-05Z TIME FRAME. PRETTY UNSTABLE...BUT MID LEVEL WINDS A BIT WEAK AND REAL GOOD SHEAR SORT OF LACKING. CURRENT ZONES ALREADY HAVE SVR MENTIONED FOR ENTIRE CWA AND WILL LEAVE AS SUCH GIVEN INSTBY. HOWEVER...AM A LITTLE CONCERNED THAT TSRA WILL HAVE A HARD TIME WORKING EASTWARD WITH FRONT NOT MOVING THAT QUICKLY AND MID-LEVEL WINDS SO WEAK. NGM ABOUT 3-5 HRS FASTER WITH FROPA THAN ETA. PREFER ETA SOLN GIVEN LACK OF GOOD PRESS RISES BEHIND FRONT AND UPR WAVE HANGING BACK UNTIL 12Z. THEREFORE...FIGURE WILL STAY ABV GUIDANCE TEMPS TNGT. PRETTY RAPID DRYING OF AMS BEHIND FRONT FOR THU. SHOULD SEE QUITE A BIT OF SUN TMRW...SO WILL HAVE TO BALANCE STRONG MAY SUN WITH MDT CAA. FAN GUIDANCE LOOKS A LITTLE COOL IF WE MIX OUT TO 850 MB TMRW...FWC CLOSER. EITHER WAY THO...WILL PROBABLY HAVE TO TRIM CURRENT HIGHS A BIT. DESPITE CLR SKIES FOR THU NIGHT...DOESNT LOOK LIKE WINDS WILL DROP OFF TO NOTHING WITH SFC RIDGE TO W. THEREFORE...THINK GUIDANCE LOOKS A LITTLE COOL. FRI SHD BE REALLY NICE...THO MAYBE STILL A BIT BLO NORM AS SFC RIDGE MOVES OVHD. USING AVN 850 TEMPS...A BLEND OF FAN AND FWC SEEMS TO BE IN ORDER.

FORECAST: SCATTERED THUNDERSTORMS ARE EXPECTED TO CONTINUE MAINLY SOUTH OF THE OUTLOOK AREA THROUGH THE AFTERNOON HOURS. THESE STORMS COULD WORK INTO THE MOUND CITY AND BUTLER AREAS...BUT ARE NOT EXPECTED TO BECOME SEVERE. THUNDERSTORMS WILL RE-DEVELOP THIS AFTERNOON ACROSS EASTERN KANSAS AND SOUTHEAST NEBRASKA. THESE STORMS ARE EXPECTED TO MOVE EASTWARD THROUGH THE OUTLOOK AREA AFTER ABOUT 4 PM. A FEW OF THESE STORMS MAY BE SEVERE LATE THIS AFTERNOON AND THIS EVENING. THE MAIN THREAT WOULD BE FROM LARGE HAIL AND DAMAGING WINDS. SPOTTER ACTIVATION MAY BE NEEDED LATE THIS AFTERNOON AND TONIGHT. DISCUSSION: MOISTURE IS RAPIDLY INCREASING ACROSS THE OUTLOOK AREA. THE INCREASE IN MOISTURE HAS HELPED TO DESTABILIZE THE ATMOSPHERE...WITH SOME ADDITIONAL DESTABILIZATION LIKELY DURING THE AFTERNOON HOURS. A COLD FRONT TO THE NORTHWEST WILL TRACK TOWARD THE AREA THIS EVENING. THIS FRONT SHOULD HELP TO FOCUS THUNDERSTORM DEVELOPMENT TO OUR WEST AND EVENTUALLY PUSH THE ACTIVITY EASTWARD INTO THE AREA. THE WIND SHEAR IS NOT REAL STRONG...BUT THE AIRMASS SHOULD BE UNSTABLE ENOUGH FOR SOME OF THE THUNDERSTORMS TO REACH SEVERE LEVELS. JM
