Area forecast discussion, May 4, 2:47 AM CDT, 1 hour 15 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
247 AM CDT FRI MAY 4 2012

.DISCUSSION...
WARM AND HUMID CONDITIONS WILL CONTINUE FOR A COUPLE MORE DAYS
BEFORE COOLER TEMPERATURES AND THUNDERSTORM CHANCES ARRIVE ON
SUNDAY...FOLLOWED BY PLEASANT NEAR NORMAL TEMPERATURES FOR MONDAY-
WEDNESDAY.

TDY-TONIGHT
ANOTHER VERY WARM AND HUMID DAY FOR KANSAS WITH TEMPERATURES IN THE
UPPER 80S AND 90S. OTHERWISE...STRONG CAPPING TEMPERATURES ALOFT
LOOK TO KEEP MOST THUNDERSTORM CHANCES AT BAY TODAY BUT A FEW LATE
AFTERNOON THUNDERSTORMS WILL BE POSSIBLE ALONG THE DRYLINE. THE MAIN
AREA WOULD BE SOUTH OF KANSAS ACROSS CENTRAL OKLAHOMA WHERE ENOUGH
CONVERGENCE COULD SPARK OFF ISOLATED THUNDERSTORMS.

SAT-SUN
WARM AND HUMID YET AGAIN ON SATURDAY FOR KANSAS WITH WARM
TEMPERATURES ALOFT CAPPING THE ATMOSPHERE FROM THUNDERSTORM
DEVELOPMENT. STILL CANNOT RULE OUT AN ISOLATED THUNDERSTORM OR TWO
ALONG THE DRYLINE WITH A WEAK UPPER LEVEL WAVE MOVING EAST ACROSS
KANSAS. WE WILL KEEP THE FORECAST DRY AS MOST AREAS WOULD REMAIN
DRY. COOLING RELIEF FROM THE HEAT LOOKS TO BE ON THE WAY COME
SUNDAY...AS A STRONG COLD FRONT SURGES SOUTHWARD ACROSS KANSAS.
THUNDERSTORM CHANCES WILL BE POSSIBLE AGAIN FOR AREAS ALONG AND
BEHIND THE FRONT ON SUNDAY.

EXTENDED: MON-THU
COOLER DRIER AIR WILL SPREAD SOUTHWARD ACROSS THE CENTRAL PLAINS FOR
MONDAY-WEDNESDAY...AS A DEEP UPPER WAVE DROPS SOUTHWARD FROM THE
SOUTHERN CANADA INTO THE GREAT LAKES REGION. DAYTIME HIGHS WILL BE
CLOSER TO NORMAL VALUES AND WINDS LOOK TO LIGHTEN UP SOME AS SURFACE
HIGH PRESSURE REMAINS IN CONTROL. NEXT UPPER WAVE WILL MOVE SLOWLY
EASTWARD FROM THE SOUTHWESTERN STATES WITH MOISTURE BEGINNING TO
STREAM NORTHWARD TOWARDS KANSAS ON THURSDAY. WE WILL KEEP THE
FORECAST DRY DUE TO UNCERTAINTY ON TIMING/EVOLUTION OF THIS NEXT
SYSTEM...SOMETHING FOR LATER SHIFTS TO KEEP TABS ON.

JAKUB

AVIATION...06Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
AVIATION CONCERNS STILL REMAIN SOME MVFR CONDITIONS FOR EARLY FRI
MORNING.

NOT MUCH HAS CHANGED SINCE THE LAST TAF ISSUANCE. STILL EXPECTING
VISIBILITIES TO LOWER TO BETWEEN 3-6SM AFTER 09Z. IN ADDITION SOME
MVFR CIGS MAY ALSO CREEP INTO CENTRAL KS. THE MOST LIKELY AREAS FOR
THESE MVFR CONDITIONS WILL BE OVER CENTRAL KS WHERE SOME WEAK
SURFACE CONVERGENCE SHOULD ALLOW FOR SOME MOISTURE POOLING AND
REDUCED MIXING. CONFIDENCE REMAINS HIGH THAT STORMS WILL STAY
NORTHEAST OF OUR TAF SITES.
