.PREV DISCUSSION... /ISSUED 423 AM CDT MON OCT 20 2014/

DISCUSSION...
A FEW SHOWERS AND PERHAPS A RUMBLE OR TWO OF THUNDER HAVE
DEVELOPED ACROSS NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS. THIS
ACTIVITY WILL CONTINUE INTO THE MORNING HOURS AS IT MOVES
SOUTHEAST...BUT SHOULD DISSIPATE BY AROUND MIDDAY. QUIET WEATHER
WITH ABOVE NORMAL TEMPERATURES SHOULD THEN PREVAIL FROM THIS
AFTERNOON THROUGH WEDNESDAY AS UPPER LEVEL RIDGING TAKES HOLD.

AN UPPER LEVEL STORM SYSTEM WILL MOVE ACROSS THE NORTHERN PLAINS
INTO THE UPPER MIDWEST WEDNESDAY NIGHT AND THURSDAY. AN UPPER TROF
WILL EXTEND SOUTH FROM THIS SYSTEM AND WILL BRING SCATTERED SHOWERS
AND THUNDERSTORMS TO OUR AREA WEDNESDAY NIGHT AND THURSDAY.

ONCE THIS SYSTEM PASSES...A STRONG UPPER RIDGE FOR THIS TIME OF
YEAR WILL BUILD EAST INTO THE AREA. THE RESULT WILL BE
TEMPERATURES WARMING TO WELL ABOVE THE SEASONAL NORMALS NEXT
WEEKEND. THE RIDGE LOOKS TO BREAK DOWN EARLY NEXT WEEK WHICH WILL
ALLOW A COLD FRONT TO SWEEP ACROSS THE AREA...ACCOMPANIED BY A
CHANCE OF SHOWERS AND THUNDERSTORMS.

STAYED CLOSE TO GUIDANCE TEMPERATURES THE NEXT COUPLE DAYS.
