Area forecast discussion, Aug 24, 3:21 PM CDT, 6 hours 55 minutes before

AREA FORECAST DISCUSSION...CORRECTED POPS IN CENTRAL KS
NATIONAL WEATHER SERVICE WICHITA KS
321 PM CDT FRI AUG 24 2001

EFFECTS OF UPPER LOW SEEN SPINNING EAST ACROSS SRN NE ARE THE MAIN
CONCERNS TO ADDRESS FOR THIS FORECAST. MODELS ARE IN GOOD AGREEMENT
THAT THIS UPPER FEATURE CONTINUES TO SHIFT EAST...KEEPING GOOD
THETA-E/WAA ACROSS SRN/EASTERN KS THROUGH 09Z. LATEST LOOK
AT SFC ANAYLSIS SHOWS BOUNDARY PREVIOUS LOCATED ACROSS NRN OK HAS
WASHED OUT...LEAVING ANY LOW LEVEL CONVERGENCE IN NC ZONES.
THEREFORE WILL KEEP POPS IN THE SCT RANGE AND WILL KEEP SEVERE
WORDING OUT. AS SFC BOUNDARY PUSHES THROUGH NRN ZONES...MOST OF THE
PRECIP THERE SHOULD OCCUR DURING THE EVENING HOURS.

FOR SATURDAY...MODELS INDICATE A SECONDARY WEAKER SHORTWAVE TO SLIDE
SOUTHEAST THROUGH THE FORECAST AREA...BUT MAIN 7H TROF IS THROUGH
MUCH OF CENTRAL KS BY 12Z SATURDAY...SO WILL REMOVE POPS FROM NRN
ZONES AND CONFINE PCPN CHANCES TO THE MORNING IN ICT ZONES. ETA
1000-850MB THICKNESS FORECAST SUGGEST TEMPS WILL BE WARMER THAN
GUIDANCE...BUT PREVIOUS ZONES HAVE A GOOD HANDLE ON THIS TREND.

AVN BRINGS 40KT UPPER LEVEL SPEED MAX SOUTH ACROSS WESTERN KS
OVERNIGHT SATURDAY...BUT WITH BEST LOW LEVEL WAA REMAINING SOUTH OF
THE FORECAST AREA...WILL KEEP DRY FORECAST IN PLACE AND WITH SFC
RIDGE SETTLING ACROSS THE WESTERN ZONES WILL GO BLO GUIDANCE VALUES
FOR LOWS SATURDAY NIGHT.

WITH SFC RIDGE OVER THE AREA SUNDAY WILL KEEP SFC WINDS LIGHT...THUS
LIMITING MIXING. HOWEVER...ETA 1000-850MB THICKNESSES INCREASE FROM
SATURDAY/S VALUES SO WILL BUMP UP HIGHS A CATEGORY FROM THE PREVIOUS
FORECAST FOR SUNDAY/S HIGHS.

EXTENDED...ECMWF SEEMS TO BE THE ODD MODEL OUT IN DEEPENING EASTERN
USA TROF...WITH UKMO/CANADIAN/MRF ALL SHOWING A LESS AMPLIFIED
PATTERN. AS A RESULT...TEMPS EARLY NEXT WEEK MIGHT NOT BE A COOL AS
PREVIOUSLY THOUGHT...SO WILL WARM HIGHS A LITTLE FROM MON-WED.
IN ADDITION...WITH UPPER RIDGE SOUTH OF THE AREA...WEAK SHORTWAVE
ENERGY ROTATING AROUND THE RIDGE MAY BRING SCT PCPN THUR AS HINTED
BY CANADIAN AND SHOWN BY THE MRF.
