.PREV DISCUSSION... /ISSUED 258 AM CDT SUN JUL 27 2014/

DISCUSSION...

ONE LAST DAY OF HEAT AND HUMIDITY FOR THE FORESEEABLE
FUTURE...WITH MUCH ANTICIPATED COLD FRONT ALMOST ON OUR DOORSTEP.
DRIER AIR AND SLIGHTLY COOLER TEMPERATURES IMMEDIATELY BEHIND THE
FRONT THIS AFTERNOON SHOULD KEEP PARTS OF NORTHEAST OKLAHOMA
FROM SEEING THE HEAT INDICES OF THE PAST FEW DAYS. MOST OF
EASTERN OKLAHOMA AND WEST CENTRAL ARKANSAS WILL SEE HEAT INDICES
IN THE 105 TO 110 RANGE WITH MOISTURE POOLING AHEAD OF THE FRONT
AND TEMPERATURES IN THE UPPER 90S. ONLY CHANGE TO THE HEAT
HEADLINES IS TO CANCEL THE HEAT ADVISORY AND EXCESSIVE HEAT
WARNING FOR AREAS ALONG AND NORTH OF HIGHWAY 412...EXCEPT FOR
TULSA COUNTY. STRONG TO SEVERE THUNDERSTORMS REMAIN POSSIBLE
ALONG THE FRONT PRIMARILY THIS AFTERNOON AND EVENING...WITH
DOWNBURST WINDS BEING THE GREATEST SEVERE THUNDERSTORM THREAT.
THUNDERSTORMS MAY CONTINUE OVERNIGHT AND POSSIBLY INTO MONDAY
MORNING...BUT THE INTENSITY SHOULD DIMINISH WITH LOSS OF DAYTIME
HEATING.

COOLER WEATHER AND LARGELY DRY CONDITIONS WILL PREVAIL MONDAY AND
TUESDAY...WITH HIGHS LIKELY TO BE AROUND 5 DEGREES BELOW NORMAL.
WIDESPREAD SHOWERS AND THUNDERSTORMS LOOK TO MOVE INTO PARTS OF
EASTERN OKLAHOMA AND POSSIBLY WESTERN ARKANSAS DURING THE DAY
WEDNESDAY...WITH INCREASING CHANCES WEDNESDAY NIGHT AND INTO
THURSDAY...AS A SERIES OF DISTURBANCES IN THE NORTHWEST UPPER
LEVEL FLOW AFFECT THE REGION. SEVERE WEATHER DOES NOT LOOK
LIKELY...BUT HEAVY RAIN AND LOCALIZED FLOODING COULD BECOME AN
ISSUE. 1 TO 3 INCHES OF RAIN...WITH LOCALLY HIGHER AMOUNTS...COULD
FALL DURING THE WEDNESDAY TO THURSDAY TIME FRAME MAINLY ACROSS PARTS
OF EASTERN OKLAHOMA...AND PERHAPS INTO WEST CENTRAL ARKANSAS.

BELOW NORMAL TEMPERATURES SHOULD HANG AROUND THROUGH NEXT WEEKEND
AND PROBABLY INTO AT LEAST THE BEGINNING OF THE FOLLOWING WEEK.
AFTER THE WEDNESDAY/THURSDAY RAINS...CONDITIONS SHOULD BE LARGELY
DRY...WITH ONLY A SMALL CHANCE OF DAYTIME SHOWERS/THUNDERSTORMS
FRIDAY AND SATURDAY.
