Area forecast discussion, Aug 10, 3:10 AM CDT, 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
310 AM CDT SUN AUG 10 2008

.DISCUSSION...

MAIN FORECAST CONCERN IS TIMING THE ENDING OF HEAVY RAIN IN
SOUTHEASTERN KANSAS IN THE NEAR TERM.

TODAY-MONDAY:
ONGOING CONVECTION ACROSS SOUTH CENTRAL/SERN KS OCCURRING WITHIN
NW-SE ORIENTED 850 CONVERGENCE ZONE THAT THE MODELS PROGGED FAIRLY
WELL ON LAST NIGHTS RUNS. 35KT SWRLY LOW-LEVEL JET IS FOCUSING
MOISTURE TRANSPORT INTO THIS CONVERGENCE ZONE. STILL GETTING 1 TO
1.5 INCH/HOUR RAINFALL RATES WITH THIS CONVECTION IN SERN KS/FLINT
HILLS ALONG WITH REPORTS OF FLOODING. SHORT RANGE WRF/GFS PROG THE
LOW-LEVEL JET TO VEER IN THE 12Z-15Z TIME FRAME WHICH SHOULD ALLOW
THE HEAVIEST RAINS TO MOVE SEWD OUT OF SERN KS. WILL NIX THE FLOOD
WATCH FOR A FEW COUNTIES IN THE NWRN PART OF THE WATCH WHERE
CONVECTION IS ON THE WANE...BUT EXTEND IT TIL 16Z IN THE FAR SERN
COUNTIES. POPS WILL BE REDUCED TO SLIGHT CHANCE THIS PM IN THE SERN
COUNTIES (NIL ELSEWHERE) BEHIND THE DEPARTING SHORTWAVE. WILL KEEP A
15-20% POP IN THE SOUTHERN COUNTIES NEAR THE OK BORDER TONIGHT
CLOSER TO THE 850 FRONTAL ZONE. ANOTHER PIECE OF ENERGY SWEEPS
ACROSS THE NRN PLAINS MON-MON NIGHT WITH OUR FORECAST AREA PERHAPS
TOO FAR SOUTH TO GET MUCH LIFT EFFECT. WILL MAINTAIN JUST A SLIGHT
CHANCE POP ACROSS THE AREA. EASTERLY COMPONENT TO WINDS AND
SATURATED SOIL IN MUCH OF AREA WILL HELP KEEP HIGHS BELOW NORMAL
BOTH DAYS ALTHOUGH MORE IN WAY OF SUN EXPECTED MON WILL YIELD SLIGHT
MODIFICATION OF AIRMASS. FORECAST CONFIDENCE: HIGH.

TUESDAY-SATURDAY:
ECMWF AND GFS IN FAIR AGREEMENT ON THE UPPER PATTERN SHOWING NWRLY
FLOW ALOFT TUES-THURS. BOTH MODELS SHOW THE UPPER LOW OVER S-CNTRL
CANADA DEVELOPING SEWD TOWARD FRI/SAT WHICH WILL SEND A COLD FRONT
DOWN INTO KS. THIS SYSTEM WILL BRING OUR NEXT DECENT CHANCE OF
T-STORMS TOWARD THE END OF THE WEEK. TEMPERATURES SHOULD MODIFY TO
CLOSER TO NORMAL TUES-THURS AHEAD OF THE FRONT.
