AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE WICHITA KS
258 AM CDT TUE JUL 6 2004

.DISCUSSION...

MAIN FCST CONCERN WL BE THE CONVECTIVE COMPLEX TO AFFECT CWA THIS
MORNING AND THEN PRECIP CHANCES WED NGT.

WL KEEP FLOOD WATCH IN EFFECT FOR ENTIRE AREA THROUGH 10 AM AS THIS
COMPLEX CONTINUES TO TRACK SE. THOUGHT ABOUT CANCELING IT FOR
CENTRAL KS, BUT SINCE WE HAVE A FEW FLOOD WARNINGS IN EFFECT, WL
JUST LET THE WATCH DIE A NATURAL DEATH.

TDAY-TNGT:
WHERE THE SQUALL LINE WL BE AT THE TIME OF ZONE ISSUANCE WL DICTATE
THE POPS FOR TDAY. FIRST GUESS IS THAT POPS WL BE NEEDED FOR SE KS
AND MUCH OF SC KS, WITH NOTHING FOR CENTRAL KANSAS. FEEL THE BULK OF
THE CONVECTION LATE THIS AFTERNOON SHUD BE CONFINED TO AREAS SOUTH
OF THE BORDER. THIS IS WHERE BETTER LOW LEVEL CONVERGENCE WL BE
SITUATED TO GET CONVECTION GOING. HOWEVER WL PLACE A SLGT CHANCE
ALONG THE BORDER IN CASE ANYTHING CREEPS UP THERE LATE THIS
AFTERNOON. TEMPS ARE EXPECTED TO BE COOLER THAN THE LAST FEW DAYS AS
SOME SLIGHTLY COOLER AIR MOVES IN FROM THE NORTH. IN ADDITION WET
GROUND WL LIMIT HEATING POTENTIAL.

WL KEEP ENTIRE CWA DRY TNGT, BUT AM A LITTLE CONCERNED THAT A STRAY
STORM MAY DEVELOP OVER THE PANHANDLE OF OKLAHOMA AND WORK INTO THE
SW PORTION OF THE CWA. HOWEVER WL KEEP DRY AND LET NEXT SHIFT TAKE
ANOTHER LOOK AT IT.

WED-THU: UPPER FLOW WL BECOME NW WED WITH A WEAK UPPER RIDGE
SITUATED OVER THE DESERT SW. AT THE SAME TIME SOME LEE SIDE
TROUGHING WL COMMENCE ALLOWING MOISTURE TO RAPIDLY RETURN TO KANSAS.
THERE REALLY IS NOT ANY FOCUS FOR STORMS TO DEVELOP WED. WL LEAVE
POPS IN FOR WED NGT AS THE THETA E GRADIENT SHIFTS EAST AS LLJ
VEERS. ETA ALSO SHOWING SOME DECENT UPGLIDE THROUGH CWA WED NGT
ALONG WITH ELEVATED INSTABILITY INCREASING.

FRI-MON:
DID NOT MAKE TOO MANY CHANGES FROM THE PREV FCST. MED RANGE MODELS
STILL AGREE ON SW FLOW FROM THE DESERT SOUTHWEST TO THE NORTHERN
PLAINS. THEREFORE THE BETTER UPPER DYNAMICS WL REMAIN NW OF THE CWA.
HOWEVER THERE SHUD BE A PERSISTENT WEAK SFC TROUGH OVER THE HIGH
PLAINS. FEEL THAT STORMS WL DEVELOP OVER THE HIGHS PLAINS DURING THE
AFTERNOONS. SOME OF THIS ACTIVITY MAY CREEP INTO CENTRAL KS DURING
THE EVENING HOURS. THEREFORE KEPT POPS IN FOR THE EVENING PERIODS
ACROSS CENTRAL KS AND DRY DURING THE DAY. TEMPS SHUD BE PRETTY CLOSE
TO CLIMO, WITH NEAR 90 HIGHS AND UPPER 60S TO NEAR 70 LOWS.
