Area forecast discussion, Oct 22, 9:30 PM CDT, 1 hour 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
930 PM CDT SAT OCT 22 2011

...UPDATE...

.DISCUSSION...
SHOWERS TO STRONG THUNDERSTORMS CONTINUE TO PUSH SOUTHEAST ACROSS
EASTERN OKLAHOMA AND INTO NORTHWEST ARKANSAS THIS EVENING. LATEST
RADAR TRENDS HAVE INDICATED THAT THE SEVERE THREAT HAD BEGUN TO
DECREASE FROM NORTH TO SOUTH...THUS HAVE CUT A FEW COUNTIES FROM
THE SVR WATCH. HAIL AND STRONG WINDS STILL REMAIN A POSSIBILITY
WITHIN THE STRONGER STORMS. CURRENT ONGOING MCS SHOULD CONTINUE
TO PUSH SOUTHEAST OVERNIGHT AND OUT OF THE REGION DURING THE
MORNING HOURS SUNDAY.

EVENING UPDATE WILL BE TO ADJUST POPS BASED ON CURRENT AND LATEST
RADAR TRENDS. ALSO WILL UPDATE SKY AND TEMP GRIDS BASED ON THE
CLEARING LINE BEING NEAR PONCA CITY. IF THE SKIES CLEAR ENOUGH
ACROSS NORTHEAST OKLAHOMA THERE COULD BE THE POTENTIAL FOR SOME
FOG WITH TEMPS HANGING CLOSE TO THE DEWPOINT. WILL LEAVE OUT
MENTION OF FOG IN THE FORECAST FOR NOW.

UPDATES HAVE ALREADY BE SENT.
