AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
311 PM CDT MON JUL 9 2007

.DISCUSSION...
FORECAST CONCERNS ARE PRECIPITATION CHANCES AND HEAVY RAINFALL
POTENTIAL AGAIN ACROSS THE AREA THRU TUESDAY NIGHT...

TONIGHT:
MCV FROM LAST NIGHT IS CURRENTLY OVER CENTRAL KANSAS. SOME
THUNDERSTORMS HAVE DEVELOPED ON THE EASTERN EDGE OF THE MCV...AND
THESE WILL CONTINUE TO EXPAND. THE BEST CHANCES FOR PRECIPITATION
TONIGHT WILL BE ACROSS SOUTH CENTRAL KANSAS...AND LATE TONIGHT
ACROSS SOUTHEAST KANSAS. THE MAIN THREAT WITH THESE STORMS WILL BE
THE HEAVY RAINFALL...HOWEVER THERE COULD BE SOME HAIL TO NICKEL SIZE
AND 40 TO 50 MPH WINDS.

TUESDAY-WEDNESDAY:
PRECIPITATION COULD LINGER ACROSS SOUTH CENTRAL AND SOUTHEAST KANSAS
ON TUESDAY MORNING...WITH REDEVELOPMENT ACROSS THE ENTIRE AREA
POSSIBLE ON TUESDAY AFTERNOON. MOST UNSTABLE CAPE VALUES ARE AROUND
3000 TO 4000 J/KG...WITH VERY LITTLE CIN IN MUCH OF THE AREA
ESPECIALLY LATER IN THE AFTERNOON.

AFTER MIDNIGHT TUESDAY NIGHT...INSTABILITY AND MOISTURE TRANSPORT
REALLY GET PUSHED TO THE SOUTH AND EAST OF THE AREA. WITH THIS IN
MIND...KEPT SOME SLIGHT CHANCES FOR THUNDERSTORMS ACROSS SOUTHERN
KANSAS. SURFACE HIGH PRESSURE RETURNS ON WEDNESDAY...PROVIDING A
BRIEF RESPITE FROM THE WET WEATHER.

TEMPERATURES WILL REMAIN A FEW DEGREES BELOW NORMAL DURING THIS
TIME...ESPECIALLY WITH CLOUDS AND PRECIPITATION AROUND THROUGH
TUESDAY EVENING.

THURSDAY-SUNDAY:
AFTER A BRIEF DRY PERIOD...MOISTURE TRANSPORT REALLY RETURNS BY
THURSDAY MORNING ACROSS WESTERN AND CENTRAL KANSAS. WITH SOME QG
FORCING AND ISENTROPIC LIFT AT LEAST THROUGH THE LOWER TO MID
LEVELS...DECIDED TO ADD SOME CHANCES FOR PRECIPITATION FOR THURSDAY
AND THURSDAY NIGHT. LINGERING THUNDERSTORM CHANCES ON FRIDAY LOOK
REASONABLE BEFORE THE SYSTEM PUSHES OFF TO THE SOUTH AND SURFACE
HIGH PRESSURE BUILDS BACK IN. FORECAST THEN LOOKS DRY THROUGH THE
WEEKEND. TEMPERATURES ALSO LOOK REASONABLE THROUGH THIS TIME
FRAME...SO IF ANYTHING ONLY MINOR TWEAKS WERE MADE.

SCHRECK

&&

.AVIATION...
TWO AREAS OF CONCERN FOR THE TAFS.  MVFR CLOUDS IN SOUTHEAST KS AND
CONVECTION CHANCES IN SOUTH CEN AND CEN KS THIS AFTERNOON INTO THIS
EVENING.  AFTERNOON HEATING WILL SLOWLY BURN OFF THE MVFR CEILINGS
NEAR THE KCNU TAF SITE. SO WILL SLOWLY BREAK THIS OUT AS THE
AFTERNOON PROGRESSES WITH CEILINGS BECOMIG VFR.  NEXT CONCERN WILL
BE THE INSERTION OF VCTS FOR THE KICT/KHUT/KSRL AND KSLN TAF SITES
AS INSTABILITY INCREASES FOR THE EVENING HOURS ACROSS WESTERN
SECTIONS.
