AREAS AFFECTED...PARTS OF NORTHWESTERN TEXAS AND SOUTHWEST INTO
CENTRAL OKLAHOMA
CONCERNING...TORNADO WATCH 710...
VALID 181009Z - 181215Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 710 CONTINUES.
SUMMARY...A NARROW SQUALL LINE MAY CONTINUE TO POSE A RISK FOR
LOCALIZED DAMAGING WIND GUSTS AND ISOLATED BRIEF TORNADOES WHILE
APPROACHING THE I-35 CORRIDOR, INCLUDING THE OKLAHOMA CITY METRO,
THROUGH 6-8 AM CST.
DISCUSSION...A NARROW, STRONGLY FORCED SQUALL LINE, WITH EMBEDDED
MESO-GAMMA SCALE CYCLONIC CIRCULATIONS CONTINUES PROPAGATING
NORTH-NORTHEASTWARD INTO/ACROSS THE RED RIVER VALLEY VICINITY.
DOWNSTREAM OF MID-LEVEL TROUGHING TAKING ON A MORE NEGATIVE TILT
INTO AND THROUGH THE TEXAS SOUTH PLAINS, MODELS INDICATE THAT THIS
MAY BE MAINTAINED AT LEAST INTO THE 12-14Z TIME FRAME. ALTHOUGH
BOUNDARY-LAYER INSTABILITY REMAINS LIMITED ACROSS SOUTHWEST OKLAHOMA
INTO THE I-35 CORRIDOR OF CENTRAL OKLAHOMA, STRONGER SURFACE
PRESSURE FALLS IN ADVANCE OF THE DEEPENING SURFACE CYCLONE MAY ALLOW
FOR SUFFICIENT BOUNDARY-LAYER WARMING AND MOISTENING TO MAINTAIN A
RISK FOR DAMAGING WIND GUSTS AND ADDITIONAL BRIEF TORNADOES.
