AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORMAN OK
955 PM CDT SAT JUN 8 2013

.UPDATE...
ADJUSTED RAIN CHANCES FOR THE REST OF TONIGHT...TO LOWER THEM
OVER NORTHERN OKLAHOMA...AND INCREASE THEM OVER SOUTHWEST
OKLAHOMA AND WESTERN NORTH TEXAS.

&&

.DISCUSSION...
SEVERE THUNDERSTORM POTENTIAL CONTINUES TO DECREASE.

ONE OR TWO SEVERE STORMS WITH WIND GUSTS UP TO 60 MPH AS THE
MAIN HAZARD REMAIN POSSIBLE OVER WESTERN AND SOUTHWESTERN
OKLAHOMA INTO WESTERN NORTH TEXAS THROUGH ABOUT 2 AM CDT OR SO
WHERE BEST INSTABILITY...STRONGEST WIND SHEAR...AND LARGEST
SURFACE DEWPOINT DEPRESSIONS EXISTS. CONFIDENCE OF SEVERE REMAINS
LOW...ESPECIALLY AS THE SURFACE DECOUPLES SINCE NOT SURE IF
STRONGEST WINDS CAN MAKE IT DOWN TO THE GROUND. HAIL POTENTIAL
IS LOW. NO TORNADOES ARE EXPECTED.

FOR THE I-35 CORRIDOR INCLUDING THE OKLAHOMA CITY...PONCA CITY...
ARDMORE...AND DURANT AREAS...SEVERE STORMS ARE NOT EXPECTED FOR
THE REST OF TONIGHT DUE TO THE LACK OF SIGNIFICANT INSTABILITY
AND STRONG WIND SHEAR. A FEW STORMS MAY HAVE BRIEF HEAVY
DOWNPOURS AND CLOUD TO GROUND LIGHTNING STRIKES....BUT MAY
CONTINUE TO WEAKEN...THOUGH A FEW NEW STORMS HAVE DEVELOPED
NEAR GUTHRIE IN THE PAST HOUR.

PRODUCTS HAVE BEEN UPDATED.
