CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
PERIODIC IFR CONDITIONS HAVE BEEN NOTED WITHIN VICINITY OF A SLOW
MOVING COLD FRONT CURRENTLY FROM FAR NW AR TO SOUTH CENTRAL OK
WITH MVFR CONDITIONS FURTHER NORTH. THIS TREND WILL CONTINUE AS
FRONT CONTINUES TO PUSH SLOWLY SOUTHWARD. BY EVENING MVFR TO
POSSIBLY VFR CEILINGS ARE EXPECTED...AND THIS FORECAST WILL RETAIN
LOWER CEILINGS THAN MOST GUIDANCE GIVEN THE WET SOILS AND LACK OF
STRONGLY DRIER AIR. MVFR CEILINGS ARE LIKELY TO PREVAIL THROUGH
MUCH OF THURS MORNING WITH A POSSIBLE BREAK ACROSS NE OK SITES.

..UPDATE...

DISCUSSION...
EXPANSIVE CLOUD COVER AND EARLY MORNING CONVECTION HAS LARGELY
STABILIZED THE AREA AHEAD OF THE COLD FRONT WHICH IS CURRENTLY
FROM NW AR INTO SOUTH CENTRAL OK. A BAND OF LIGHT SHOWERS /
DRIZZLE HAS BEEN NOTED NEAR THE FRONTAL BOUNDARY AND THIS IS
LIKELY TO REMAIN THE EXTENT OF PRECIP THROUGH THE REMAINDER OF THE
DAY. ISOLATED ELEVATED THUNDERSTORMS MAY DEVELOP NEAR THE RED
RIVER OVERNIGHT...OTHERWISE A DRY SPELL IS UNDERWAY AND IT WILL
REMAIN RATHER BRIEF. TEMPS TODAY WERE LOWERED ACROSS NE OK GIVEN
THE CLOUD COVER AND CHILLY UPSTREAM TEMPS.
