AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
637 AM CDT FRI MAY 20 2011

...UPDATE TO AVIATION...

.DISCUSSION...

THUNDERSTORMS MAKING SLOW EASTWARD PROGRESS THROUGH CENTRAL
KANSAS OVERNIGHT AS THE UPPER LOW AND ITS ASSOCIATE SHORTWAVE DO
THE SAME. HIGH MID AND LOW LEVEL MOISTURE LEADING TO PRECIPITABLE
WATER VALUES 1.5 TO 2 TIMES NORMAL...WITH AT LEAST EQUAL LEVELS
UPSTREAM. STRONG ISENTROPIC LIFT HAS SUBSIDED SINCE
WEDNESDAY...BUT ENOUGH REMAINS WITH THE INCREASING UPPER FORCING
FOR THUNDERSTORMS TO CONTINUE TO FIRE IN SOUTH CENTRAL KANSAS AND
NORTHWEST OKLAHOMA EARLY THIS MORNING. MODERATE SHEAR AND ELEVATED
INSTABILITY LEADING TO OCCASIONAL ORGANIZED STORMS AND HEAVY RAINS
WHERE STORMS HAVE TRAINED.

UPPER TROF STILL ON TRACK TO SWING AROUND THE UPPER LOW
TODAY...PASSING THROUGH EASTERN KANSAS TONIGHT. ISENTROPIC LIFT
CONTINUES TO WANE TODAY AS THE WARM SECTOR CONTINUES TO BUILD DOWN
TO THE SURFACE...AND EXPECT MOST WIDESPREAD COVERAGE THIS MORNING.
MAY BE ENOUGH AIRMASS RECOVERY OCCUR IN THE WEST FOR THE DRYLINE TO
BE A FOCUS FOR MORE STORMS THIS AFTERNOON. AGAIN MODERATE SHEAR AND
INSTABILITY WOULD SUPPORT SOME SEVERE POTENTIAL...WITH MESOSCALE
EFFECTS FROM EARLIER CONVECTION LIKELY LEADING TO POCKETS OF
ENHANCED CONCERN SOMEWHERE IN THE VICINITY. TROFS PASSAGE SHOULD
CLEAR THINGS OUT OVERNIGHT...WITH SEVERE STORM AND HEAVY RAIN
CONCERNS UNTIL THIS HAPPENS AS THE WARM SECTOR REMAINS IN PLACE.

UPPER LOW TRANSLATES NORTHEAST INTO THE NORTHERN PLAINS SATURDAY
WITH ANOTHER SHORTWAVE STILL ON TRACK TO PASS LATE IN THE DAY. UPPER
FORCING NOT QUITE AS IMPRESSIVE AS EARLIER RUNS SUGGESTED...BUT
COOLER TEMPS ALOFT AND BETTER INSOLATION EXPECTED WILL RESULT IN
STEEPER ELEVATED LAPSE RATES FOR A HIGHER INSTABILITY LIKELIHOOD BUT
WEAKER SHEAR. WILL MAINTAIN CHANCE POPS IN THE AFTERNOON AND EVENING
GIVEN SOMEWHAT UNCERTAIN FORCING.

SUNDAY STILL ON TRACK TO BE THE DRIEST PERIOD FOR THE BULK OF THE
AREA...THOUGH SOME CONCERN REMAINS IN THE SOUTHEAST NEAR THE DEEPER
MOISTURE. WARM AIR ADVECTION REGIME RETURNS AHEAD OF THE NEXT UPPER
SYSTEM LATE SUNDAY NIGHT THROUGH MONDAY NIGHT FOR INCREASING
PRECIPITATION CHANCES....WITH MORE WET PERIODS LIKELY ON THROUGH THE
MID WEEK AS THE NEXT WAVE MOVES THROUGH THE QUICK FLOW PER 0Z GFS
AND ECMWF. AT LEAST LOCALIZED FLOODING AND A FEW BOUTS OF POTENTIAL
SEVERE WEATHER WILL BE POSSIBLE.

65

&&

.AVIATION...

VFR CIGS AND VSBYS WILL CONTINUE THROUGH 15Z THIS MORNING AND
OUTSIDE OF MOST CONVECTION. LARGE AREA OF SHOWERS AND THUNDERSTORMS
WILL GRADUALLY MOVE TOWARD THE TAF SITES THIS MORNING. MODELS A
BIT HIGH ON LOW LEVEL MOISTURE AND PRECIPITATION AND HAVE
MAINTAINED INTRODUCING MVFR CIGS/VSBYS WITH THE CONVECTION. TIMING
IS KEY AND EXPECT A ROUND LATER THIS MORNING THEN AGAIN LATER
DURING THE LATE AFTERNOON AND EVENING.
