Area forecast discussion, Apr 24, 6:50 PM CDT, 1 hour 51 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
650 PM CDT SUN APR 24 2011

.AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
WEAK SFC-850MB LOW PRESSURE SITUATED OVER ERN NM AT 25/0ZZ WILL MOVE
SLOWLY E ACROSS TX PANHANDLE TO CNTRL OK THROUGHOUT THE NGT. THIS
WOULD INDUCE CIGS TO GRADUALLY LWR OVER ALL 5 TERMINALS. LOWEST CIGS
TO OCCUR OVER KCNU WHICH WILL DETERIORATE EVEN FURTHER FROM IFR TO
LIFR THIS EVENING. WITH ISENTROPIC ASCENT STEADILY INCREASING EXPECT
REMAINING TERMINALS TO DROP INTO IFR CIG STATUS 25/06Z-25/09Z WITH -RA
SPREADING N/NE ACROSS KS...WITH MVFR VSBYS LIKELY OVER ALL 5 TERMINALS
BY 25/12Z.

&&

.PREV DISCUSSION... /ISSUED 227 PM CDT SUN APR 24 2011/

DISCUSSION...
A BROAD MID/UPPER TROUGH WAS SITUATED ACROSS THE CENTRAL GREAT BASIN
AREA AND THE SOUTHWEST STATES WHILE SOUTHWEST MID/UPPER FLOW WAS
PRESENT ACROSS THE PLAINS AND LOCATIONS DOWNSTREAM. AT THE
SURFACE...NUMEROUS SHOWERS AND THUNDERSTORMS WERE ONGOING NORTH OF
A STATIONARY FRONT ACROSS THE LOWER/MID MISSISSIPPI VALLEY AREAS
INCLUDING THE OHIO AND TENNESSEE VALLEY AREAS WHILE PARTLY TO MOSTLY
CLOUDY SKIES WERE THE RULE ACROSS KANSAS.

TONIGHT...THE STATIONARY FRONT THAT EXTENDS OVER THE SOUTHERN PLAINS
IS PROGGED TO RETURN NORTH THROUGH TONIGHT/EARLY MONDAY. THE GFS IS
MORE AGGRESSIVE BRINGING THE FRONT NORTH WHEN COMPARED TO THE
NAM/SREF LEADING TO LOWER CONFIDENCE IN WIDESPREAD WETTING RAINS
ACROSS PORTIONS OF CENTRAL AND SOUTH CENTRAL KANSAS AND WILL TREND
POPS BACK TO PRIMARILY SOUTHEAST KANSAS THROUGH AROUND 06Z. AFTER
06Z AN INCREASING LLJ/300-305K ISENTROPIC UPGLIDE MAY RESULT IN
ELEVATED STORMS ALONG AND NORTH OF H85 FRONT EXPECTED TO RESIDE
ACROSS SOUTHERN KANSAS. MAINTAINED LIKELY POPS ACROSS MUCH OF THE
AREA WITH THE HIGHEST CONFIDENCE ACROSS SOUTHEAST KANSAS WHERE
STEEPER MID LVL LAPSE RATES/ML CAPE AROUND 1200-1500 J/KG AND
SUFFICIENT 1-6KM BULK SHEAR MAY RESULT IN A FEW SEVERE THUNDERSTORMS
WITH LARGE HAIL.

LARGE-SCALE FORCING FOR ASCENT WILL CONTINUE ON MONDAY AS THE
MID/UPPER TROUGH TRANSLATES OVER THE ROCKIES AND INTO THE CENTRAL
PLAINS STATES. THE BEST CHANCE FOR A STRONG THUNDERSTORM OR TWO WILL
BE ACROSS FAR SOUTHEAST KANSAS ALONG THE COLD FRONT AS IT MOVES OVER
THE AREA DURING THE AFTERNOON HOURS. LOWERED POPS ACROSS THE WESTERN
ZONES WITH INCREASING LARGE-SCALE FORCING FOR SUBSIDENCE/ISENTROPIC
DOWNGLIDE EXPECTED LATER IN THE PERIOD.

TUESDAY-WEDNESDAY...A MEAN LARGE-SCALE TROUGH IS PROGGED TO REMAIN
ENTRENCHED ACROSS THE CENTRAL CONUS PROVIDING A CONTINUATION OF
BELOW NORMAL TEMPERATURES AND CONTINUED CHANCES FOR DEEP MOIST
CONVECTION THROUGH EARLY WEDNESDAY. THIS WAS HANDLED WELL IN THE
PREVIOUS FORECAST WITH ONLY MINOR ADJUSTMENTS MADE.

THURSDAY-SUNDAY...A MID/UPPER RIDGE WILL RETURN TO THE CENTRAL CONUS
IN THE THURSDAY-FRIDAY PERIODS WITH RISING HEIGHTS/INCREASING
THICKNESS SUPPORTING RISING TEMPERATURES AND DRY WEATHER CONDITIONS
ACROSS THE PLAINS STATES. A POTENT SHORTWAVE TROUGH IS PROGGED TO
TRANSLATE EAST ACROSS THEN NORTHERN PLAINS ON SATURDAY DRIVING A
COLD FRONT SOUTH ACROSS THE CENTRAL PLAINS RESULTING IN MORE
SEASONABLE TEMPERATURES FOR SATURDAY AND SUNDAY WITH LOW
PROBABILITIES FOR SHOWERS AND THUNDERSTORMS. BETTER CHANCES FOR
DEEP MOIST CONVECTION WILL LIKELY BE ALONG THE FRONTAL BOUNDARY
WHICH IS EXPECTED TO STALL TO THE SOUTHEAST OF THE AREA.

MWM

FIRE WEATHER...
FIRE WEATHER CONCERNS WILL REMAIN LOW THROUGH MIDWEEK WITH LIMITED
INSOLATION AND CONTINUED CHANCES FOR PRECIPITATION. NEAR CRITICAL
FIRE WEATHER CONDITIONS MAY ARRIVE TOWARD THE END OF THE WEEK WITH
INCREASING SOUTHERLY WINDS AND MILD TEMPERATURES RETURNING TO THE
REGION.
