AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
ISSUED AT 1112 PM CST WED JAN 21 2026
INTERMITTENT MVFR TO VFR CONDITIONS CAN BE EXPECTED FOR THE TAF
PERIOD BUT WITH HIGH UNCERTAINTY ON CLOUD COVERAGE. CLOUD BASES
SHOULD RANGE ANYWHERE FROM 600 TO 5000 FT BUT THE MAIN QUESTION
IS IF THESE WILL BECOME CEILINGS. IN ANY CASE, THIS SHOULD BE
THE PRIMARY IMPACT FOR THE TAF PERIOD. WINDS WILL INCREASE FROM
THE NORTHWEST OVER THE NEXT SEVERAL HOURS WITH INTERMITTENT
LIGHT SNOW POSSIBLE, CAUSING VISIBILITY REDUCTIONS TO MVFR AT
TIMES. AGAIN, THIS ALSO DEPENDS ON HOW WIDESPREAD CLOUD COVER IS
FOR IT TO BE EITHER TEMPORARY OR PREVAILING. THIS WILL CONTINUE
THROUGH THE DAY TOMORROW, BUT CLEARING SHOULD OCCUR TOMORROW
EVENING AS A SURFACE HIGH APPROACHES.
