WITH SCATTERED STRONG THUNDERSTORMS AND LOCALLY HEAVY RAIN ACROSS
MARICOPA/YUMA AND LA PAZ COUNTIES. THIS ACTIVITY CONTINUES TO PUSH

WEAKEN IN STRENGTH A BIT. ALL THIS ACTIVITY IS ASSOCIATED WITH AN

HEAVY SHOWERS AND THUNDERSTORMS TO SPREAD/DEVELOP ACROSS SOUTHEAST

HAVE CUT THEM BACK SEVERAL DEGREES FROM EARLIER FORECAST. THE MAIN
PART OF THE UPPER LEVEL TROUGH WILL BE IN NEW MEXICO FRIDAY MORNING

WEDNESDAY BRINGING A DRIER NORTHWEST FLOW ALOFT WHICH MAY BE THE
