AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
200 AM CDT FRI JUL 27 2001

...PRELIMINARY DISCUSSION...
MAIN FCST CONCERNS ARE PRECIP CHCS AND TEMPS. TWO AREAS OF PRECIP
ONGOING. AREA OF TSRA DEVELOPING ALONG THETA-E RIDGE AXIS WILL
PERSIST ACROSS THIS AREA AND SINK SE. MEANWHILE MCS WILL CONTINUE
IT/S E/SE TREK PER CORFIDI VECTORS. WOULD EXPECT THIS TO BE THROUGH
THE FCST AREA BY LATE MORNING. HAVE LEANED TOWARD THE ETA SINCE IT
HAS THE BEST HANDLE ON THE MCS. SFC BOUNDARY SOUTH OF THE OK BORDER
SHOULD START TO PUSH NORTH TODAY AHEAD OF APPROACHING SHORTWAVE.
FCST SOUNDINGS SHOW CEN AND SE KS TO BE UNCAPPED. APPEARS SCEN
SECTION WILL HAVE A HARDER TIME GETTING PRECIP SO WILL HAVE LOWER
POPS THERE. SHORTWAVE MOVING ACROSS THE NORTHERN PLAINS WILL SEND A
FRONT ACROSS PORTIONS OF KS TONIGHT. THIS MAY GET ANOTHER MCS GOING
ACROSS WESTERN KS WHICH WOULD THEN MOVE ACROSS THE FCST AREA. ETA IS
STRONGEST WITH THIS LOOKING AT 500MB UVV. WILL HAVE HIGHER POPS
ACROSS SCEN/SE SECTIONS. WILL CONTINUE CHCS OF RAIN DURING THE DAY
SAT AS MODELS LEAVE A BOUNDARY ACROSS THE AREA...BUT THINK MOST OF
THE DAY WILL BE DRY. WILL HAVE ANOTHER SHOT AT SOME RAIN SAT NIGHT.
ALTHOUGH THINK THE BEST CHANCE IS TONIGHT.

TEMPS WILL BE TRICKY WITH BOUNDARIES AND SCT TSRA AROUND THE AREA.
ETA THICKNESSES SUGGEST TEMPS RANGING FROM THE MID 90S ACROSS THE
SOUTH TO AROUND 90 IN THE NORTH TODAY. HIGHS SAT SHOULD BE SIMILAR
TO FRI DEPENDING ON WHERE THE SFC BOUNDARY SETS UP. WESTERN SECTIONS
MAY BE A BIT WARMER. MODEL THICKNESSES INCREASE FOR SUNDAY. SO WILL
STICK WITH WARMER TEMPS SUNDAY. CURRENT FCST HAS A GOOD HANDLE
ON THIS AND WILL NOT MAKE ANY BIG CHANGES.

SPECIFIC TEMPS/POPS WILL BE OUT AFTER 330AM.

NRR

.ICT...NONE.
