(THIS EVENING THROUGH NEXT SUNDAY)

HOT AND HUMID CONDITIONS WILL BE THE MAIN TOPIC THIS WEEK AS THE
REGION REMAINS UNDER THE EASTERN PERIPHERY OF A RIDGE ALOFT.
A COLD FRONT IS STRETCHED FROM OK, ACROSS AR, AND INTO THE OHIO
VALLEY. WEAK TROUGHING ALOFT IS OVER THE GREAT LAKES INTO THE SE
STATES WITH A SHORT WAVE OVER AR MOVING ALONG THE BASE OF THE
TROF. A DECAYING MCS IS DIVING SE ACROSS N LA AND CENTRAL MS AHEAD
OF THE AFOREMENTIONED FEATURES.
A RIDGE ALOFT IS BUILDING OVER NORTHERN MEXICO AND THE SW STATES.
THROUGH THE REMAINDER OF TODAY AND INTO THE EVENING THE DECAYING
MCS AND ITS ASSOCIATED OUT FLOW BOUNDARY WILL CONTINUE SE. A FEW
SHOWERS HAVE DEVELOPED OVER CEN LA WITH DAYTIME HEATING, AND
ADDITIONAL THUNDERSTORMS MAY BE POSSIBLE AS THE OUTFLOW BOUNDARY
SCRAPES BY RAPIDES AND AVOYELLES PARISHES. COVERAGE, HOWEVER WILL
REMAIN ISOLATED.
THE COLD FRONT WILL CONTINUE TO MOVE SE TUESDAY AND WEDNESDAY WITH
MORE CONVECTION POSSIBLE ALONG THE BOUNDARY. WHILE THE VAST
MAJORITY OF THE STORMS WILL REMAIN REMOVED FROM THE LOCAL AREA,
THERE IS A SLIM CHANCE THAT THE ASSOCIATED OUTFLOW BOUNDARIES
MOVE INTO CEN LA AND SPARK A THUNDERSTORM OR TWO. OTHERWISE, THE
AREA'S WEATHER WILL BE DOMINATED BY THE UPPER RIDGE THAT IS
BUILDING OVER THE SW STATES. THIS WILL KEEP THE AREA LARGELY
PRECIP FREE THROUGH THE WEEK AND INTO THE WEEKEND. HOWEVER, LESS
CLOUD COVER A PRECIP MEANS TEMPS WILL BE RUNNING SLIGHTLY ABOVE
NORMAL WITH MAX APPARENT TEMPS RUNNING NEAR HEAT ADVISORY
CRITERIA, ESPECIALLY ACROSS INLAND LOCATIONS.
