DISCUSSION...
/ISSUED 200 PM CDT WED JUN 30 2010/

PLEASANT WEATHER CONDITIONS FOR THE LAST DAY OF JUNE PREVAILED
ACROSS THE REGION. FAIR WEATHER CUMULUS AND TEMPERATURES IN THE
LOWER 80S WERE THE RULE AT EARLY AFTERNOON.

HIGH PRESSURE ALOFT AND AT THE SURFACE WILL CONTINUE TO DOMINATE
OUR WEATHER THE REMAINDER OF THE WEEK WHILE HURRICANE ALEX MAKES
LANDFALL SOUTH OF THE TEXAS BORDER. THE FLOW AROUND THE SURFACE
RIDGE EXTENDING FROM EASTERN CANADA WILL MAINTAIN SLIGHTLY BELOW
NORMAL TEMPERATURES AND A RELATIVELY DRY AIRMASS INTO THURSDAY
NIGHT.

THE UPPER LEVEL RIDGE CENTERED OVER THE CENTRAL PLAINS WILL BECOME
POSITIONED OVER THE OZARKS BY LATE WEEK. RISING 50H HEIGHTS AND
WARMING 850 MB TEMPERATURES WILL BRING TEMPERATURES BACK TO
SEASONAL SUMMER LEVELS AS WE START JULY.

A RETURN FLOW WILL SET UP THIS WEEKEND AS THE SURFACE AND UPPER
LEVEL RIDGE MIGRATE TO THE EAST. DEEPER MOISTURE POTENTIALLY
ENHANCED BY THE REMNANTS OF ALEX WILL BE TRANSPORTED NORTHWARD
AROUND THE PERIPHERY OF THE RIDGE. THE CHANCE OF CONVECTION MAY
DEVELOP AS EARLY AS LATE SATURDAY WITH BETTER CHANCES COMING
SUNDAY INTO MONDAY AS A WEAK FRONT APPROACHES FROM THE NORTHWEST.
SOME QUESTION IF THE FRONT WILL MAKE IT ALL THE WAY ACROSS THE
AREA BY THE MIDDLE OF NEXT WEEK.
