.PREV DISCUSSION... /ISSUED 402 PM CDT SUN JUL 27 2014/

DISCUSSION...
BAND OF SHOWERS AND THUNDERSTORMS NEAR THE KANSAS BORDER HAS
MAINTAINED ITSELF THROUGHOUT THE DAY AS IT SLOWLY DROPS SOUTHEAST.
MAY YET SEE A FEW ISOLATED STORMS DEVELOP NEAR THE WIND SHIFT FROM
NORTHWEST ARKANSAS INTO SOUTHEAST OKLAHOMA. THUS WILL CARRY LOW
POPS EVERYWHERE THIS EVENING...ALTHOUGH 20 PERCENT IS LIKELY
OVERKILL GIVEN THE EXPECTED LOW COVERAGE. A BETTER CHANCE OF
SHOWERS AND STORMS WILL EXIST LATE TONIGHT INTO EARLY MONDAY
MORNING ACROSS FAR SOUTHEAST OKLAHOMA.

COOLER AND MUCH DRIER AIR WILL INVADE THE AREA FOR MONDAY AND
TUESDAY. RAIN CHANCES WILL BEGIN TO INCREASE TUESDAY NIGHT AND
ESPECIALLY WEDNESDAY INTO THURSDAY AS A COUPLE UPPER LEVEL
DISTURBANCES ROTATE SOUTH AND SOUTHEAST AROUND THE UPPER TROF TO
OUR EAST. THE POTENTIAL DOES EXIST FOR ONE OR BOTH OF THOSE DAYS
TO BE EVEN COOLER THAN FORECAST IN SOME PLACES IF WIDESPREAD RAIN
DOES INDEED OCCUR.

RAIN CHANCES WILL LESSEN AS WE HEAD INTO THE WEEKEND AND AFTERNOON
TEMPERATURES WILL CLIMB WELL INTO THE 80S...WHICH IS STILL 5-10
DEGREES BELOW THE SEASONAL NORMALS.

STAYED CLOSE TO GUIDANCE TEMPERATURES THE NEXT COUPLE DAYS.
