.PREV DISCUSSION... /ISSUED 1048 AM CDT SAT AUG 30 2014/

DISCUSSION...
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS HAVE OCCURRED THIS
MORNING IN FAR EASTERN OKLAHOMA AND NORTHWEST ARKANSAS A HEAD OF A
WEAK 700 MB SHORTWAVE AND ALONG THE BACK EDGE OF A PLUME OF DEEP
LOW AND MID-LEVEL MOISTURE STREAMING NORTH FROM THE WESTERN GULF.
THIS ACTIVITY WILL CONTINUE INTO THE AFTERNOON AND INCREASE DURING
THE TIME OF PEAK HEATING.  THE MID-LEVEL SYSTEM WILL BE SLOW TO
TRANSLATE EAST BEING NEAR THE OKLAHOMA AND ARKANSAS BORDER AT
00Z AND EXTENDING ACROSS FAR SOUTHEAST OKLAHOMA.

THE DEEP MOISTURE ENVIRONMENT WHERE THE THUNDERSTORMS OCCUR WILL KEEP
THE TEMPS DOWN A LITTLE...SO POTENTIAL FOR EVEN AN ISOLATED SEVERE
REPORT SEEMS ALMOST NIL AT THE MOMENT...BUT THE RISK FROM LIGHTNING
SHOULD ALWAYS BE CONSIDERED AROUND STORMS.
