Area forecast discussion, Apr 25, 3:51 AM CDT, 6 hours 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
351 AM CDT FRI APR 25 2008

.DISCUSSION...
COLD FRONT TO OUR NORTHWEST WILL SWEEP THROUGH THE REGION TODAY.
SHOWERS AND SCATTERED THUNDERSTORMS WILL BUILD SOUTHWARD AS THE
COMBINATION OF A WEAKENING CAP ALONG WITH STRONG LOW LEVEL
CONVERGENCE AND LIFT WITH THE FRONT WILL TRIGGER SHOWERS AND
THUNDERSTORMS BEGINNING AROUND SUNRISE.  WENT ABOVE GUIDANCE
ON POPS FOR TODAY PARTICULARLY IN NORTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS. EXPECTING THUNDERSTORMS TO BUILD SOUTH INTO AREA ALONG
AND AHEAD OF THE FRONT. WITH INCREASING LOW LEVEL SHEAR DURING THE
DAY...AFTERNOON/EVENING AND GOOD ELEVATED INSTABILITY...THUNDERSTORMS
WILL HAVE A HAIL/WIND THREAT.

TIMING OF THE SYSTEMS OVER THE WEEKEND AND INTO NEXT WEEK IS
FAIRLY CONSISTENT IN THE MODELS BUT TIMING BECOMES DIFFICULT AT BEST
AND LIKELY NEARLY IMPOSSIBLE JUDGING BY THE DIFFERENCES TOWARDS
THE MIDDLE OF NEXT WEEK. HAVE GONE WITH A BLEND OF VARIOUS MODELS
BUT PREFER THE ECMWF.

AS USUAL FOR LATE APRIL...STRONG SWINGS IN TEMPERATURES AND
ATMOSPHERIC MOISTURE WILL BE THE RULE OVER THE NEXT WEEK.
