.PREV DISCUSSION... /ISSUED 400 AM CDT MON SEP 22 2014/

DISCUSSION...
COLD FRONT HAS PUSHED ALONG THE INTERSTATE 20 CORRIDOR EARLY THIS
MORNING WITH A NARROW BAND OF VERY LIGHT SHWRS...WHICH HAVE BEEN
WEAKENING OVER THE PAST HOUR. THIS IS LIKELY DUE TO THE INCREASING
SURGE OF MUCH DRIER AIR BEHIND THE FRONT BEING FURTHER REINFORCED
BY AN UPPER TROF AXIS WHICH EXTENDS FROM THE ERN GREAT LAKES SOUTH
TO THE MID MS VALLEY. DEW POINTS HAVE ALREADY FALLEN INTO THE MID
TO UPPER 50S AND LOWER 60S OVER OUR NRN TIER...WHILE STILL NEAR 70
FARTHER SOUTH ALONG AND AHEAD OF THE FRONT. THIS DRY AIR PUSH WILL
HELP TO CHOKE OFF CONVECTION LATER TODAY BUT HAVE KEPT IN SLIGHT
CHANCE POPS SOUTH OF I-20 AS THE FRONT ADVANCES THIS MORNING AND
THROUGH THE AFTERNOON.

BEHIND THE FRONT...NOTICEABLY COOLER TEMPERATURES WILL FOLLOW OVER
THE NEXT FEW DAYS JUST IN TIME FOR THE OFFICIAL START TO THE FALL
SEASON. OVERNIGHT LOWS WILL BE IN THE 50S AREA WIDE FOR THE NEXT
COUPLE OF MORNINGS BEFORE GRADUALLY MODERATING BACK CLOSER TO THE
SEASONAL AVERAGES FOR LATE SEPTEMEBER AS THE UPPER LEVEL RIDGE
REASSERTS CONTROL OVER OUR REGION. THIS WILL SPELL ANOTHER
EXTENDED PERIOD OF DRY WEATHER WITH RAIN CHANCES SLIM TO NONE
THROUGH LATE NEXT WEEKEND. /19/
