AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
644 PM CDT SAT APR 14 2012

.AVIATION...
THE CURRENT SEVERE CONVECTION IS UNLIKELY TO AFFECT ANY OF OUR TAF
SITES OTHER THAN KVNX THIS EVENING...AS WE EXPECT THE CAP TO
REMAIN TOO STRONG FOR STORMS TO FORM MUCH FARTHER S THAN THE
CURRENT STORMS. A NEW CONVECTIVE LINE IS FORECAST TO FORM AROUND
15/0500Z AS A COLD FRONT OVERTAKES THE DRYLINE AND PRESSES E
ACROSS OK AND N TX. THIS LINE IS LIKELY TO AFFECT ALL OUR SITES
BY THE TIME IT EXITS TO THE E OF KOKC/KOUN AROUND 15/1000Z. SOME
BLDU MAY REACH FAR NW OK THIS EVENING...REDUCING VSBYS TO 3 TO 6
SM AT TIMES.

.PREV DISCUSSION... /ISSUED 252 PM CDT SAT APR 14 2012/

DISCUSSION...
SIG SEVERE WEATHER EVENT BEGINNING TO UNFOLD ACROSS NORTHWEST
OKLAHOMA AND HIGH-RES MODELS INDICATE THAT WE WORST CONDITIONS
THROUGH THE AFTERNOON WILL BE OVER NORTHWEST/WEST-CENTRAL INTO
NORTH-CENTRAL OKLAHOMA WITH INTENSE SUPERCELLS AND POSSIBLY LONG-
TRACK TORNADOES. MODELS DECREASE THE THREAT THE FARTHER SOUTH YOU
GO...AT LEAST INITIALLY WITH SUPERCELLS. LATE THIS EVENING AND
OVERNIGHT THERE IS STILL A FAIRLY SUBSTANTIAL SIGNAL THAT SEVERE
SQUALL-LINE WILL FORM AND SWEEP OVER MUCH OF THE REGION.
RELATIVELY HIGH POPS WERE RETAINED FOR THIS. THIS LINE IS PROGD TO
SURGE THROUGH CENTRAL OKLAHOMA NEAR/JUST AFTER MIDNIGHT AND EXIT
FAR SOUTHEAST OKLAHOMA TOWARD SUNRISE SUNDAY. DAMAGING WINDS AND
EVEN EMBEDDED SHORT-LIVED TORNADOES POSSIBLE WITH THE LINE SO WE
SHOULD NOT LET OUR GUARD DOWN AFTER INITIAL DISCRETE SUPERCELL
MODE IS OVER.

NO CHANGES MADE TO REMAINING PERIODS WITH TRANQUIL WEATHER
EXPECTED UNTIL LATE NEXT WEEK.
