318 PM CDT MON SEP 24 2007

.DISCUSSION...
THE CHANCE FOR PCPN THROUGH TUESDAY...TEMPERATURES THE NEXT SEVERAL
DAYS AND THE CHANCE OF PCPN LATE IN THE WEEK ARE THE MAIN FORECAST
CONCERNS. WATER VAPOR LOOP EARLY THIS AFTERNOON SHOWED A CLOSED LOW
OVER NERN UT AND SWRN WY. A DECENT BAND OF MOISTURE STRETCHED FROM
MEXICO ACROSS TX AND UP INTO MN. SO FAR...TSTM COVERAGE HAS BEEN
MOSTLY FROM NWRN IA ACROSS MN. ANOTHER BAND OF MOISTURE EXTENDED
FROM THE GULF OF MEXICO NORTH ACROSS LA AND UP INTO WI. THE 20Z
SURFACE ANALYSIS SHOWED A COLD FRONT FROM NWRN IA INTO NWRN KS.
GUSTY WIND AND COOL TEMPERATURES WERE NOTED BEHIND THE FRONT...
WITH SOME READINGS ONLY IN THE 40S AND 50S. AHEAD OF THE FRONT...
TEMPERATURES WERE IN THE 80S WITH DEWPOINTS IN THE 60S.

AS OF 315 PM...COVERAGE OF STORMS SEEMED TO BE ON THE INCREASE...
AND CAP WAS ERODING. LEFT HIGH POPS GOING THROUGH TONIGHT OR WENT
WITH AREAL COVERAGE WORDING...ESPECIALLY BEFORE 06Z. THINK THAT

TO NEAR 60 FAR SERN CORNER OF NE.

THE CHANCE FOR PCPN SHOULD DECREASE TUESDAY MORNING...AND DID NOT
MENTION ANY PCPN TUESDAY AFTERNOON. HIGH PRESSURE SHOULD BUILD
OVER THE AREA BY LATE TUESDAY. MIXING WONT BE GOOD...AND HIGHS IN
THE 60S SEEM APPROPRIATE. A GENERAL TROUGHINESS TO THE 500 MB FLOW
IS EXPECTED ACROSS THE NRN AND CNTRL PLAINS INTO THURSDAY...THEN A
WEAK RIDGE BUILDS EAST FROM THE ROCKIES. THERE ARE SOME FAIRLY
MAJOR MODEL TIMING DIFFERENCES THAT HOPEFULLY WILL WORK THEMSELVES
OUT THE NEXT FEW DAYS. 12Z GFS WAS FASTER IN MOVING SURFACE HIGH
PRESSURE EAST THURSDAY NIGHT INTO FRIDAY...AND IT STARTED TO DVLP
WARM ADVECTION PCPN FRIDAY. DID NOT GO QUITE THAT FAST...BUT WILL
MENTION CHANCE OR SLIGHT CHANCE OF TSTMS FROM FRIDAY NIGHT INTO
SATURDAY. TROUGH AXIS SHIFTS EAST BY SUNDAY...WITH RIDGING ACROSS
THE AREA INTO MONDAY.
