.UPDATE...
ALREADY SENT UPDATE TO TWEAK POPS FOR THE REMAINDER OF THE MORNING
HOURS INTO THIS AFTERNOON. ELEVATED SHOWERS/THUNDERSTORMS CONTINUE
TO DEVELOP ACROSS NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS. THE
COLD FRONT IS LOCATED JUST NORTHWEST OF CWA...CURRENTLY MOVING
THROUGH NORTH CENTRAL OKLAHOMA. A FEW OF THE ELEVATED STORMS COULD
BE STRONG THIS MORNING...BUT THE PRIMARY CHANCE FOR SEVERE WEATHER
SHOULD BE LATER THIS AFTERNOON ACROSS NORTHWEST ARKANSAS AS COLD
FRONT MOVES INTO AFOREMENTIONED AREA. SEVERE POTENTIAL WILL LIKELY
DEPEND ON HOW WIDESPREAD ELEVATED CONVECTION BECOMES AND HOW MUCH
SURFACE BASED INSTABILITY CAN BE MAINTAINED/REALIZED WITH MAIN
FRONTAL BOUNDARY. REGARDLESS...WIND FIELDS ALOFT WILL BE MARGINAL
...KEEPING OVERALL SEVERE WEATHER CHANCES MORE LIMITED THAN
OTHERWISE EXPECTED WITH A FROPA IN MID MAY.
