Area forecast discussion, Mar 25, 9:35 PM CST, 2 hours 4 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
935 PM CST THU MAR 25 2004

A FEW THUNDERSTORMS CONTINUE TO DEVELOP OVER EXTREME NORTHWEST
OKLAHOMA IN AN AREA OF MODERATELY HIGH CAPE VALUES... APPARENTLY
SUPPORTED BY A SMALL UPPER-LEVEL WAVE.  THE CAP IS VERY STRONG OVER
CENTRAL OKLAHOMA... ACCORDING TO THE 00Z NORMAN SOUNDING.  OTHER
STORMS OVER TEXAS HAVE WANDERED INTO AN AREA OF RELATIVELY LOW CAPE
AND STRONG CAP... WHICH HAVE SERVED TO CONVERT THE STORMS INTO ANVIL
RAIN.

THE 40KM ETA CONTINUES TO SHOW AN MCS DEVELOPING OVERNIGHT OVER
MISSOURI AND VICINITY... SPREADING SOUTHWEST INTO CENTRAL OKLAHOMA.
GIVEN THE CAP... THE WEAK RIDGING ALOFT THAT IS ALSO FORECAST... THE
AREA COVERED SEEMS TOO LARGE.  OUR EXISTING LOW POPS SEEM ADEQUATE
FOR LATE TONIGHT.

A FEW MINOR TWEAKS TO HOURLY TEMPERATURES AND MORE-DETAILED POPS
APPEAR TO BE APPROPRIATE AT THIS TIME... AND THOSE MODIFICATIONS
SHOULD BE AVAILABLE AROUND 10 PM.

23 = CMS
-------------------------------------------------------------------
345 PM CST THU MAR 25 2004

FIRST CONCERN IS THE POTENTIAL FOR CONVECTION IN THE WEST THIS
EVENING. SOME CONVECTION IS DEVELOPING ALONG THE DRYLINE... MAINLY
DOWN NEAR LUBBOCK... BUT ALSO HAVE SEEN SOMETHING TRYING TO GO IN
THE NORTHEAST PANHANDLES.  WILL KEEP SLIGHT CHANCE POPS IN THE WEST
FOR THIS EVENING. AS WE PROGRESS THROUGH THE OVERNIGHT... A
SHORTWAVE WILL APPROACH THE AREA AND GIVE AN INCREASED CHANCE OF
PRECIP OVERNIGHT... BUT STILL SOME UNCERTAINTY ON DEVELOPMENT OR HOW
WIDESPREAD IT WILL BECOME SO KEEP POPS 20-30.

MESSY FORECAST FOR A COUPLE OF DAYS WITH A DIFFERENCE OF OPINION OF
THE TIMING OF THE MAIN UPPER TROUGH THROUGH THE AREA AS WELL AS THE
SUBTLE FEATURES THAT MAY TRY TO PRODUCE CONVECTION.  SO WILL BE
PRETTY BROAD WITH THE POPS THROUGH SUNDAY UNTIL SURFACE FRONT AND
UPPER TROF FINALLY MOVE THROUGH.
