AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
230 PM CDT TUE MAY 28 2013

.DISCUSSION...
SHOWERS/THUNDERSTORMS WILL BE POSSIBLE THROUGH TONIGHT ACROSS PARTS
OF OKLAHOMA AND WESTERN NORTH TEXAS. A FEW SHOWERS/STORMS HAVE
DEVELOPED ACROSS NORTH CENTRAL OK EARLY THIS AFTN AND COULD CONTINUE
TO DEVELOP OVER THE NEXT SEVERAL HOURS. VISIBLE SATELLITE SHOWS CU
DEVELOPING ALONG THE DRYLINE IN FAR NW OK AND THE TX/OK PANHANDLES.
CONVECTION IS EXPECTED TO DEVELOP IN THIS AREA AND AFFECT WESTERN
PORTIONS OF THE FA. THESE STORMS COULD BE SEVERE PRODUCING LARGE
HAIL AND DAMAGING WIND GUSTS. THIS ACTIVITY COULD MOVE FURTHER EAST
LATER THIS EVENING INTO CENTRAL PARTS OF THE FA. SEVERE STORMS WILL
STILL BE POSSIBLE WITH THESE STORMS. EVEN THOUGH LARGE HAIL WILL
STILL BE POSSIBLE... DAMAGING WIND GUSTS WILL BE THE PRIMARY CONCERN
IN THESE AREAS.

THE BEST POTENTIAL FOR SEVERE WX WILL BE WEDNESDAY. DRYLINE WILL
DEVELOP OVER THE OK/TX PANHANDLES AGAIN TOMORROW WITH AN MID/UPPER
WAVE MOVING FROM THE ROCKIES INTO THE SOUTHERN/CENTRAL PLAINS. THERE
WILL BE STRONG INSTABILITY AND THIS WAVE WILL PROVIDE BETTER WIND
SHEAR FOR THE SEVERE STORMS WEDNESDAY. VERY LARGE HAIL... DAMAGING
WINDS... AND EVEN A FEW TORNADOES WILL BE POSSIBLE WEDNESDAY. SEVERE
STORMS WILL ALSO BE POSSIBLE THURSDAY WITH A FRONTAL BOUNDARY ALSO
BEING IN OR NEAR THE AREA. HOWEVER... THE EVOLUTION OF THE STORM
ACTIVITY THURSDAY WILL BE DEPENDENT ON WHAT HAPPENS WEDNESDAY/WED
NIGHT.

THE FRONT WILL GRADUALLY MOVE SOUTH FRIDAY/SATURDAY. THE SEVERE
POTENTIAL WILL BE LOWER THESE DAYS BUT HEAVY RAIN/FLOODING COULD
BECOME AN ISSUE ACROSS PARTS OF THE FA... WITH THE MOST LIKELY AREA
TO CURRENTLY BE CONCERNED WITH WOULD BE ACROSS NORTH CENTRAL OK.
MODELS THEN SHOW THAT THINGS COULD START TO DRY OUT IN SOME OF THE
FA INTO EARLY NEXT WEEK BUT RAIN CHANCES MAY NOT GO COMPLETELY AWAY
FOR THE ENTIRE AREA. IN ADDITION... BREEZY/STRONG WINDS WILL AFFECT
THE AREA FOR THE NEXT SEVERAL DAYS.
