Warning decision update, from the National Weather Service, Norman, for Central and Southern Oklahoma
THIS WARNING DECISION UPDATE CONCERNS CENTRAL AND SOUTHERN OKLAHOMA.
LINEAR CONVECTION EXTENDING FROM OKLAHOMA CITY TOWARD DUNCAN…AND
MOVING NORTHEAST…HAD BECOME BETTER DEFINED AND TAKEN ON A BOWING
STRUCTURE. THIS LINE SHOULD MAINTAIN INTENSITY AS IT MOVES ACROSS
THE NORTHERN REACHES OF AN INSTABILITY AXIS THAT LAY ALONG AND
EITHER SIDE OF INTERSTATE 35. DESPITE BOWING STRUCTURE…SURFACE
WINDS HAD FAILED TO RESPOND TO MORE THAN GUSTS OF 30 OR 35 MPH. COOL
AND STABLE LOW LEVEL AIR RESIDING OVER CENTRAL OKLAHOMA SHOULD HELP
TO KEEP WIND GUSTS BELOW SEVERE LEVELS THROUGH EARLY AFTERNOON.
GREATER WIND POTENTIAL WOULD BE TOWARD SOUTH CENTRAL OKLAHOMA…
WHERE TEMPERATURES WERE WARMER…AND A SHALLOW INVERSION WILL BE
ENTIRELY MIXED OUT FOR TEMPERATURES OF ABOUT 73 DEGREES. STILL…THE
THREAT MAY BE LIMITED BY THE TENDENCY FOR CONVECTION TO LIFT OUT OF
THE INSTABILITY AXIS…WHILE SUBSIDENCE TO THE SOUTH OF A JET STREAK
LIMITS NEW DEVELOPMENT IN THE RED RIVER AREA.
