AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1208 AM CDT SUN JUN 10 2007

.AVIATION...
ANTICIPATING FAIRLY NUMEROUS THUNDERSTORM ACTIVITY TONIGHT ACROSS
THE AREA. DECIDED TO GO VCTS MOST AREAS...AND WITH THUNDERSTORM
CLUSTER TO THE SOUTH AND WEST OF WICHITA...DECIDED TO GO WITH A
TEMPO GROUP AT ICT. NOT ANTICIPATING WIDESPREAD SEVERE
ACTIVITY...BUT SMALL HAIL...GUSTY WINDS...FREQUENT LIGHTNING AND
TORRENTIAL RAINFALL WILL DEFINITELY BE POSSIBLE. ADDITIONAL
ACTIVITY MAY DEVELOP OVER EASTERN/NORTHEAST KANSAS WITHIN THE NEXT
2-3 HOURS.

.PREV DISCUSSION... /ISSUED 1030 PM CDT SAT JUN 9 2007/

UPDATE...
WILL SEND OUT ANOTHER QUICK UPDATE.

NUMEROUS THUNDERSTORM ACTIVITY NOW GETTING GOING ACROSS NORTHERN
OKLAHOMA/SOUTHERN KANSAS IN AN EAST/WEST FASHION...LIKELY BEING
AIDED BY INTENSIFYING LOW-LEVEL JET ON NORTHERN EDGE OF BEST
INSTABILITY. 500M AGL PROFILERS AND SURFACE DATA ALSO INDICATE A
SUBTLE EAST/WEST BOUNDARY ACROSS NORTHERN OKLAHOMA. ACTIVITY OVER
NORTHEAST OK IS DISSIPATING...LIKELY BECAUSE IT WAS DIURNAL IN
NATURE AND LOW-LEVEL JET HASNT FOCUSED THAT FAR EAST YET. GIVEN
MARGINAL DEEP LAYER SHEAR AND GOOD INSTABILITY...THIS ACTIVITY MAY
PRODUCE MARGINALLY SEVERE HAIL...AS WELL AS TORRENTIAL RAINFALL AND
GUSTY WINDS.

MEANWHILE...SQUALL LINE CONTINUES TO PROGRESS EAST/SOUTHEAST ACROSS
SOUTHWEST KANSAS. CORFIDI VECTORS CONTINUE TO POINT THIS COMPLEX
TOWARD SOUTHWEST PORTIONS OF THE FORECAST AREA. FOR THE MOST
PART...ACTIVITY HASNT BEEN SEVERE FOR QUITE SOME TIME NOW...LIKELY
DUE TO COLD POOL/SHEAR IMBALANCE...EVIDENT IN GUST FRONT SURGING OUT
AHEAD OF CURRENT CONVECTION. ANTICIPATE MUCH OF THE SAME TO CONTINUE
AS IT POSSIBLY MOVES INTO THE FORECAST AREA LATER TONIGHT. ALL IN
ALL...NOT ANTICIPATING WIDESPREAD SEVERE TONIGHT...BUT CANT RULE
OUT A WARNING OR TWO. THINKING SIGNIFICANT WEATHER ALERTS WILL
HANDLE A MAJORITY OF ACTIVITY.

KLEINSASSER

PREV DISCUSSION... /ISSUED 907 PM CDT SAT JUN 9 2007/

UPDATE...
OUTFLOW BOUNDARY CONTINUES TO APPROACH SOUTHEAST KANSAS FROM THE
SOUTH. MAY SEE A FEW STORMS DEVELOP ALONG AND BEHIND THIS
BOUNDARY OVER THE NEXT FEW HOURS...BUT THINKING THREAT IS SLOWLY
WANING DUE TO LOSS OF DAYTIME HEATING AND WEAK SHEAR. COULD SEE
SMALL HAIL AND GUSTY WINDS WITH THIS ACTIVITY.

ANOTHER AREA OF STORMS IS CURRENTLY PROGRESSING EAST ACROSS
WEST/SOUTHWEST KANSAS...LIKELY BEING AIDED BY A WEAK MID/UPPER
LEVEL DISTURBANCE. ACTIVITY HAS QUICKLY EVOLVED INTO A SQUALL
LINE. GIVEN EAST/SOUTHEAST FORWARD PROPAGATION VECTORS AND STORMS
MOVING INTO BETTER MOISTURE/INSTABILITY...DO NOT SEE A REASON WHY
THIS ACTIVITY WONT MAKE IT INTO WEST/SOUTHWEST PORTIONS OF THE
FORECAST AREA BY MIDNIGHT OR SO. HOWEVER...GIVEN MARGINAL
SHEAR...WOULD EXPECT COLD POOLS TO EVENTUALLY OUTRUN THE
CONVECTION...WANING THREAT FOR WIDESPREAD SEVERE WIND GUSTS.

A THIRD AREA OF STORMS MAY DEVELOP LATE TONIGHT ACROSS NORTHEAST
KS ALONG NOSE OF GREATEST LOW-LEVEL MOISTURE TRANSPORT...AND
CLOSER TO NORTHERN/EASTERN EDGE OF MID-LEVEL CAP. THIS ACTIVITY
MAY HAVE THE POTENTIAL TO PRODUCE MARGINALLY SEVERE HAIL GIVEN
SLIGHTLY BETTER SHEAR.

KLEINSASSER

PREV DISCUSSION... /ISSUED 640 PM CDT SAT JUN 9 2007/

AVIATION...
00Z TAFS...VFR CONDITIONS FOR THE MOST PART EXPECTED OVER THE NEXT
24 HOURS. HOWEVER...FAIRLY DRAMATIC LOW-LEVEL MOISTURE RETURN IS
CURRENTLY UNDERWAY ACROSS THE FORECAST AREA...AND STRONG 850MB
MOISTURE TRANSPORT SHOULD CONTINUE THROUGH THE NIGHT.
CONSEQUENTLY...AN ISOLATED THUNDERSTORM OR TWO CANNOT BE RULED OUT
ACROSS THE FORECAST AREA. ADDITIONALLY...THUNDERSTORM ACTIVITY
CURRENTLY OVER WESTERN KANSAS/EASTERN COLORADO MAY BE ABLE TO
SUSTAIN ITSELF EASTWARD AMIDST STRENGTHENING LOW-LEVEL JET AND
INCREASING INSTABILITY. IF THIS ACTIVITY CAN MAKE IT INTO THE
FORECAST AREA...IT WONT BE UNTIL LATE TONIGHT. ALL IN
ALL...THUNDERSTORM THREAT TONIGHT APPEARS TOO LOW/CONDITIONAL TO
WARRANT VCTS WORDING IN TAFS.

KLEINSASSER

PREV DISCUSSION... /ISSUED 312 PM CDT SAT JUN 9 2007/

DISCUSSION...

MAIN FORECAST CONCERNS ARE PRECIPITATION CHANCES FOR THE NEXT WEEK.

TONIGHT:
WEAK UPPER DISTURBANCE WILL MOVE THROUGH THE REGION TONIGHT.
SOUNDINGS ARE SHOWING A DECENT CAP THROUGH THE NIGHT ACROSS THE
FORECAST AREA. BUT WITH THE LOW LEVEL JET BRINGING MOISTURE FROM THE
SOUTH...WOULD NOT BE SURPRISED TO SEE A FEW STORMS THIS EVENING.
KEPT THE PRECIPITATION CHANCES LOW SINCE WE EXPECT ANY THUNDERSTORMS
THAT DO DEVELOP WILL BE ISOLATED. WHILE EXPECTATIONS FOR SEVERE
WEATHER ARE LOW...IT IS POSSIBLE THAT THERE COULD BE SOME PENNY SIZE
HAIL IN ONE OR TWO OF THE STORMS LATE TONIGHT.

SUNDAY-MONDAY:
DEWPOINTS INCREASE THROUGH THE NIGHT TONIGHT...AND WITH MORE
MOISTURE AVAILABLE WOULD EXPECT TO SEE MORE WIDESPREAD CONVECTION BY
SUNDAY AFTERNOON. AT THIS TIME IT DOES NOT LOOK LIKE WIDESPREAD
SEVERE STORMS...AS THERE WILL BE NO WELL DEFINED BOUNDARY IN THE
AREA. IF THERE ARE ANY SEVERE STORMS IN THE FORECAST AREA...WOULD
EXPECT THEM TO BE ACROSS THE NORTHEAST PART OF THE AREA.

TUESDAY-FRIDAY:
ABOVE NORMAL TEMPERATURES STILL LOOK REASONABLE FOR NEXT
WEEK...HOWEVER THE TEMPERATURES MAY NOT BE QUITE AS WARM AS WE
ORIGINALLY THOUGHT IF THERE ARE MORE CLOUDS AROUND. THIS WILL BE
SOMETHING TO KEEP AN EYE ON.

PRECIPITATION CHANCES ARE LOOKING MORE PROMISING FOR TUESDAY AND
WEDNESDAY. GFS BRINGS THE SURFACE LOW A LITTLE FURTHER EAST NOW
BEFORE IT STALLS OVER WESTERN KANSAS. FORECAST SOUNDINGS ARE SHOWING
DEEPER MOISTURE THROUGH THE ATMOSPHERE AS WELL. WE INCREASED THE
CHANCES FOR PRECIPITATION TO ACCOUNT FOR THIS.
