PREV DISCUSSION... /ISSUED 350 AM CDT MON MAY 13 2013/

DISCUSSION...
HIGH PRESSURE OVER THE REGION WILL BEGIN TO DRIFT OFF TO THE
EAST. TEMPERATURES ARE EXPECTED TO BE A FEW DEGREES HIGHER TODAY
THAN YESTERDAY. IN ADDITION...EAST WINDS BECOMING SOUTHEAST LATER
THIS AFTERNOON.

THIS DOME OF HIGH PRESSURE WILL CONTINUE ITS MIGRATION OFF TO THE
EAST AND LOOKS TO BECOME ESTABLISHED ALONG THE SOUTHEAST COAST OF
THE US BY WEDNESDAY. THIS WILL ALLOW MOISTURE TO WORK ITS WAY UP
THE TEXAS COAST AND INTO OUR REGION. AS A RESULT THERE IS A CHANCE
FOR SOME SHOWERS RETURNING ON WEDNESDAY AS THE RIDGE ALOFT BREAKS
DOWN A BIT. THE RIDGE IS EXPECTED TO REBUILD ON THURSDAY AND THIS
WILL PUSH THE MOISTURE BACK TO THE WEST ENDING THE RAIN THREAT.
OTHERWISE... A VERY QUIET WEATHER PATTERN THIS WEEK WILL ALLOW FOR
THE REGION TO DRY OUT FROM THE RAINS OVER THE WEEKEND.  19
