Area forecast discussion, May 15, 2:56 PM CDT, 2 hours 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
256 PM CDT THU MAY 15 2014

.DISCUSSION...

ANOTHER COOL DAY WITH ISOLATED AFTERNOON SHOWER/THUNDERSTORM
DEVELOPMENT ACROSS PARTS OF EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS. SOME OF THE SHOWERS/STORMS MAY LINGER INTO THE EARLY TO
MID EVENING HOURS BEFORE THE BOUNDARY PASSING THROUGH THE REGION
FINALLY CLEARS THE AREA. UNSEASONABLY COOL TEMPERATURES...NEAR
RECORD LOW VALUES...WILL AGAIN OCCUR TONIGHT. IF ANY SITES SEE
RECORD LOWS TOMORROW MORNING...IT WOULD MOST LIKELY BE
FAYETTEVILLE. TULSA AND FORT SMITH LOOK SAFE IN THAT DEPARTMENT.

NORTHWEST FLOW ALOFT WILL KEEP THE TRAIN OF UPPER DISTURBANCES
THROUGH THE AREA INTO AT LEAST THE EARLY PART OF THE WEEKEND.
EVENING AND OVERNIGHT SHOWERS AND STORMS WILL BE LIKELY PRIMARILY
ACROSS NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS TOMORROW EVENING
AND INTO SATURDAY MORNING...WITH ANOTHER ROUND SATURDAY NIGHT AND
INTO SUNDAY. LOW SEVERE STORM CHANCES WILL EXIST WITH EACH
ROUND...WITH PERHAPS SLIGHTLY HIGHER CHANCES FOR SUNDAY DUE TO
INCREASED MOISTURE. CERTAINLY DOES NOT LOOK LIKE ANY SLAM DUNK
WIDESPREAD SEVERE WEATHER DURING THIS TIME FRAME.

UPPER LEVEL RIDGING WILL BUILD INTO THE PLAINS FOR MUCH OF NEXT
WEEK...BRINGING DRY WEATHER AND MUCH WARMER TEMPERATURES. STILL
APPEARS THAT HIGHS AROUND 90 WILL BE POSSIBLE FOR PARTS OF THE
AREA TUESDAY AND WEDNESDAY.
