AREAS AFFECTED...NORTH CENTRAL OKLAHOMA
CONCERNING...TORNADO WATCH 137...
VALID 240140Z - 240345Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 137 CONTINUES.
SUMMARY...THE RISK OF TORNADOES REMAINS CONCENTRATED OVER
NORTH-CENTRAL OKLAHOMA FOR THE NEXT FEW HOURS.
DISCUSSION...SUPERCELLS HAVE BEEN PRODUCING STRONG TORNADOES, MOST
RECENTLY WITH A LONE STORM ALONG THE DRYLINE AND JUST SOUTH OF ENID
OK, WITH OTHERS WITHIN THE COMPLEX STORM CLUSTER FROM KAY INTO OSAGE
COUNTIES. THE LARGE CAPE, STEEP MIDLEVEL LAPSE RATE ENVIRONMENT
CONTINUES TO SUPPORT TREMENDOUS UPDRAFTS, WHILE THE LOW-LEVEL JET
INCREASES IN SPEED, ENHANCING SHEAR.
EVEN IF STORMS EVENTUALLY MERGE, THE STRONG LOW-LEVEL SHEAR AND
AMPLE INSTABILITY WILL STILL FAVOR PERIODIC ROTATION/TORNADOES,
ALONG WITH DAMAGING WINDS LATER THIS EVENING.
