LONG TERM
(FRIDAY THROUGH THURSDAY)
ISSUED AT 110 PM CDT THU MAY 7 2026
GUSTY SOUTHERLY WINDS AND NOTICEABLY WARMER TEMPERATURES EXPECTED
FRIDAY AHEAD OF WEAK COLD FRONT WHICH WILL APPROACH NE OK EARLY TO
MID AFTERNOON. MOISTURE RETURN WILL BE ONGOING BUT LIMITED IN
MAGNITUDE AS SFC RIDGING CURRENTLY EXTENDS THROUGH THE WESTERN
GULF. DESPITE THE LESSER MOISTURE RETURN, GUIDANCE IS IN GOOD
AGREEMENT DEVELOPING AN UNSTABLE AND WEAKLY CAPPED AIRMASS AHEAD
OF THE COLD FRONT BY MID AFTERNOON AND SCATTERED STORMS ARE LIKELY
TO DEVELOP AND SPREAD EAST AND SOUTHEASTWARD THROUGH FRIDAY
EVENING. SUFFICIENT INSTABILITY COUPLED WITH STRONGER DEEP LAYER
SHEAR WILL SUPPORT STRONG MULTICELL TO SUPERCELL STORM MODE WITH
THE MORE PERSISTENT UPDRAFTS. LARGE HAIL AND LOCALLY STRONG
OUTFLOW WINDS WILL BE THE PREDOMINANT CONCERNS THROUGH EARLY
EVENING. EXPECT A NOTABLE DOWNTREND IN SEVERE POTENTIAL AFTER
SUNSET.
THE COMBINED OUTFLOW / COLD FRONT BOUNDARY LIKELY BECOMES ALIGNED
FROM THE RED RIVER CORRIDOR OF SE OK INTO NW OK BY SATURDAY
AFTERNOON. GUIDANCE CONTINUES TO VARY ON BOTH THE PLACEMENT AND
MAGNITUDE OF THE EVENTUAL INSTABILITY CORRIDOR IN PLACE BY
SATURDAY EVENING. THE SCENARIO OF STORMS DEVELOPING WEST OF THE
LOCAL REGION AND SPREADING EASTWARD THROUGH SATURDAY REMAINS THE
GENERAL IDEA, HOWEVER THE OVERALL STORM COVERAGE AND PERSISTENCE
INTO THE DAY SUNDAY IS MORE UNCERTAIN.
THE WAVE PASSING SUNDAY IS EXPECTED TO DRIVE THE ASSOCIATED COLD
FRONT WELL SOUTH OF THE REGION ALLOWING FOR A DRY START TO THE
WORK WEEK. THE NEXT FRONT ARRIVES IN THE MONDAY NIGHT TO TUESDAY
TIME FRAME ACCOMPANIED BY THE NEXT CHANCE OF SHOWERS AND STORMS.
