STORMS ACROSS NORTHWEST TX WEST OF ABILENE HAVE EXHIBITED A DISTINCT
WEAKENING TREND OVER THE PAST HOUR...AND WITH LIMITED LARGE SCALE
SUPPORT AT THIS TIME...THE LIKLIHOOD OF ADDITIONAL/WIDESPREAD
DEVELOPMENT APPEARS UNCERTAIN THROUGH SUNSET OWING TO EXISTING
CIRRUS CANOPY. FARTHER NORTH...THE RELATIVELY MOST
ORGANIZED/SUSTAINED ACTIVITY WILL LIKELY CONTINUE ACROSS WESTERN
INTO CENTRAL OK AND PERHAPS FAR NORTH TX. IN ASSOCIATION WITH A
NORTHWARD ADVANCING WARM FRONT...A MOIST/UNSTABLE AIRMASS CONTINUES
TO QUICKLY NOSE INTO OK AHEAD OF CURRENT STRONG/SEVERE CLUSTER OF
STORMS CURRENTLY ACROSS WEST CENTRAL OK. THESE STORMS COULD REACH
PORTIONS OF THE OKC METRO AREA BEFORE 2230Z/530 PM CDT...WITH A RISK
OF LARGE HAIL/STRONG WIND GUSTS.
