AREAS AFFECTED...NORTH-CENTRAL OKLAHOMA
CONCERNING...SEVERE THUNDERSTORM WATCH 250...
VALID 300116Z - 300315Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 250
CONTINUES.
SUMMARY...THE POTENTIAL FOR ISOLATED OCCURRENCES OF LARGE HAIL
AND/OR SEVERE WIND GUSTS WILL PERSIST FOR THE NEXT COUPLE OF HOURS.
DISCUSSION...AS OF 01:10 UTC, A SERIES OF SMALL STORMS WERE LOCATED
FROM SOUTHERN NOBLE INTO GARFIELD AND GRANT COUNTIES, TO THE NORTH
OF AN OUTFLOW BOUNDARY. IT'S UNCLEAR WHETHER THAT CONVECTION IS
TRULY SURFACE-BASED OR SLIGHTLY ELEVATED. IN EITHER CASE, AMPLE
INSTABILITY (SEE 00 UTC OUN SOUNDING) PERSISTS WITHIN THE INFLOW AIR
MASS. BOTH THE KTLX AND KVNX VWPS INDICATE A GRADUAL INCREASE IN
WIND SPEED IN THE LOWEST 1.0-1.5 KM AGL, A TREND WHICH IS EXPECTED
TO CONTINUE THROUGH MID TO LATE EVENING. A RESULTANT INCREASE IN
STORM-RELATIVE INFLOW MAY SUPPORT STORM INTENSIFICATION WITH
ATTENDANT RISK FOR LARGE HAIL AND PERHAPS LOCALLY SEVERE WIND GUSTS
FOR THE NEXT COUPLE OF HOURS.
THE CURRENT EXPECTATION IS THAT THE REMAINING VALID PORTION OF THE
WATCH WILL BE ALLOWED TO EXPIRE AT 03 UTC.
