DISCUSSION...
HIGH PRESSURE CENTERED ALONG THE UPPER MISSISSIPPI VALLEY WAS
DOMINATING THE WEATHER ACROSS THE REGION THIS MORNING. THE HIGH
WILL DRIFT SLOWLY EAST TO THE ATLANTIC BY SUNDAY AS THE NEXT
SYSTEM MOVING TOWARD THE WEST COAST BEGINS TO TAKE SHAPE.
AS THIS SYSTEM ADVANCES SLOWLY EAST OVER THE NEXT COUPLE OF
DAYS...LARGE SCALE LIFT WILL BEGIN TO DEVELOP ACROSS THE REGION.
IN THE LOWER LEVELS...THE RETURN OF SOUTH TO SOUTHEAST WINDS ON
THE BACK SIDE OF THE EASTERN U.S. HIGH WILL BRING MOISTURE BACK
INTO THE REGION. WEAK ISENTROPIC LIFT WILL BEGIN AS EARLY AS
SATURDAY MORNING OVER WESTERN PORTIONS OF THE AREA...SPREADING
EAST ACROSS LOUISIANA AND SOUTHERN ARKANSAS SATURDAY NIGHT. THE
HIGHEST RAIN CHANCES ARE EXPECTED SUNDAY...WHEN A PIECE OF THE
SYSTEM BREAKS OFF AND MOVES ACROSS OKLAHOMA. THIS TROUGH WILL
BRING ANOTHER COLD FRONT SOUTHWARD ACROSS THE REGION...ENDING THE
RAIN BY SUNDAY EVENING. TOTAL QPF AMOUNTS INDICATE MOST OF THE
FORECAST AREA WILL RECEIVE AROUND A HALF INCH OF RAIN WITH
NORTHERN AREAS RECEIVING UP TO ONE INCH. THE BREAK IN RAIN WILL
LAST UNTIL TUESDAY...WHEN THE CUTOFF CENTER OF THE SYSTEM REACHES
SOUTH TEXAS. THIS WILL AID IN THE DEVELOPMENT OF A SURFACE LOW IN
THE NORTHERN GULF...WHICH WILL SPREAD ADDITIONAL MOISTURE INTO THE
AREA THROUGH WEDNESDAY. MOST OF THE RAINFALL FROM THIS WILL BE
CONCENTRATED IN SOUTHERN PORTIONS OF THE CWA AND SHOULD END BY
THURSDAY.

TEMPERATURES THROUGH THE SEVEN DAYS WILL REMAIN ON THE COOL SIDE...
WITH HIGHS MOST DAYS RUNNING BELOW NORMAL DUE TO CLOUDS AND RAIN.
