AREAS AFFECTED...PARTS OF CENTRAL OKLAHOMA INTO WESTERN NORTH TEXAS
CONCERNING...TORNADO WATCH 86...
VALID 020118Z - 020315Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 86 CONTINUES.
SUMMARY...THE RISK OF DAMAGING WINDS AND A COUPLE TORNADOES
CONTINUES ACROSS TORNADO WATCH #86.
DISCUSSION...AN MCS IS TRACKING SLOWLY EASTWARD ACROSS WESTERN OK
AND WESTERN NORTH TX, WITH EMBEDDED SUPERCELL STRUCTURES ON THE
SOUTHERN PORTION OF THE LINE ALONG/SOUTH OF THE RED RIVER. OVER THE
NEXT COUPLE HOURS, THE RISK OF A COUPLE TORNADOES, DAMAGING WINDS,
AND LARGE HAIL SHOULD BE MAXIMIZED WITH THE SOUTHERN STORMS
ALONG/SOUTH OF THE RED RIVER, WHERE UNSTABLE INFLOW AND STRONG
LOW/DEEP-LAYER SHEAR (AROUND 300 M2/S2 0-1 KM SRH PER FDR VWP) IS IN
PLACE.
FARTHER NORTH IN WESTERN/CENTRAL OK, A MESSIER CONVECTIVE MODE
EVOLUTION HAS LIMITED THE TORNADO RISK THUS FAR, WITH PRIMARILY A
DAMAGING-WIND RISK. HOWEVER, THE OUN 00Z SOUNDING SHOWS AMPLE
SURFACE-BASED BUOYANCY/STEEP LAPSE RATES AND A LARGE
CLOCKWISE-CURVED HODOGRAPH (265 M2/S2 EFFECTIVE SRH) IN THE
PRE-CONVECTIVE ENVIRONMENT. THIS COULD STILL SUPPORT EMBEDDED
MESOVORTICIES/SUPERCELL STRUCTURES WITH A RISK OF A COUPLE TORNADOES
AND SEVERE WIND GUSTS TOWARD THE I-35 CORRIDOR.
