AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
326 PM CDT TUE JUL 28 2015

.DISCUSSION...
A FEW SHOWERS HAVE JUST BEGUN TO DEVELOP ACROSS THE
FORECAST AREA. SOME COULD INTENSIFY INTO THUNDERSTORMS BUT ALL
ACTIVITY SHOULD BE FAIRLY SHORT LIVED AND BEGIN DISSIPATING WITHIN
THE NEXT COUPLE HOURS.

AN UPPER RIDGE CURRENTLY CENTERED OVER MISSOURI WILL BEGIN
RETROGRADING WEST BENINNING WEDNESDAY AND REMAIN OVER THE 4-CORNERS
REGION THRU THE WEEKEND. AT THE SAME TIME...AN UPPER LEVEL TROUGH
DIPPING OUT OF CANADA WILL GRADUALLY DIGS SOUTHEAST ACROSS THE
EASTERN HALF OF THE COUNTRY. THIS WESTWARD MOVEMENT OF THE RIDGE
WILL OPEN THE CWA BACK UP TO TYPICAL AFTERNOON THUNDERSTORMS. RAIN
CHANCES WILL BE IN THE 30 TO 50 PERCENT RANGE WED ONWARD. SOME
ENHANCEMENT OF COVERAGE WILL BE POSSIBLE AS A WEAK AREA OF LOW
PRESSURE OVER THE NORTHWESTERN GULF OF MEXICO DRIFTS NORTH AND
STRETCHES SW TO NE WHILE A WEAK FRONTAL BOUNDARY MOVES IN FROM THE
NORTHWEST FRIDAY & INTO NEXT WEEK.

SURFACE LOW DRAPED ACROSS THE NORTHEAST GULF NORTHERN FLORIDA WILL
DRAW WINDS INTO IT WHICH WILL RESULT IN NWRLY WINDS OVER THE COASTAL
