Severe Thunderstorm Warning 271, NWS Norman, OK

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
841 PM CDT SUN MAY 27 2001

DESPITE WIDESPREAD SEVERE T-STORMS ACROSS N OK... WHICH WILL SWEEP
SE ACROSS MOST IF NOT ALL OF THE REST OF THE CWA OVERNIGHT...
PREVIOUS FORECAST PACKAGE COVERED THINGS SO WELL THAT ONLY MINOR
ADJUSTMENTS ARE NEEDED AT THIS TIME. WILL DROP THE PROBABILITY
WORDING ACROSS N AND CENTRAL OK, AND UP POPS TO LIKELY/CATEGORICAL
IN THE S, AS SOLID LINE OF CONVECTION ALONG LEADING EDGE OF MCS
ENSURES THAT NEARLY ALL AREAS WILL GET A PIECE OF THE ACTION.
STORMS AND ASSOCIATED SEVERE POTENTIAL WILL DECREASE BY OR JUST
AFTER MIDNIGHT IN THE N AS THE COMPLEX MOVES S OF THESE AREAS. MAIN
SEVERE THREAT EXPECTED TO BE DAMAGING WINDS AS THE ASSOCIATED COLD
POOL ACCELERATES SE-WARD, BUT LARGE HAIL ALSO WILL REMAIN A THREAT
WITH SOME OF THE CORES. FLASH FLOOD THREAT APPEARS TO BE LESSENING
AS THE PRIMARY CONVECTIVE LINE IS PERPENDICULAR TO THE MOTION
VECTOR, REDUCING THE THREAT OF TRAIN ECHOES. STILL NEED TO KEEP A
MENTION OF HEAVY RAINFALL, THO.

ZONE UPDATE OUT BY 9 PM. ANOTHER UPDATE WILL BE NEEDED AROUND
MIDNIGHT TO ADDRESS TEMPORAL WORDING AND UPDATE THE PROGRESS OF THE
MCS.
