DISCUSSION
(THIS AFTERNOON THROUGH NEXT MONDAY)
ISSUED AT 1133 AM CST WED JAN 7 2026
SIMILAR CONDITIONS TO THIS MORNING ARE EXPECTED OVERNIGHT TONIGHT,
WITH PATCHY FOG EXPANDING ACROSS THE REGION. THANKFULLY, I DON'T
EXPECTED THIS FOG TO BE AS DENSE, WITH THE BEST PROBABILITIES FOR
DENSE FOG REMAINING IN OUR SOUTHERN COUNTIES. ANOTHER DENSE FOG
ADVISORY MAY BE NEEDED INTO TOMORROW MORNING, BUT MY CONFIDENCE IS
LOW WHEN IT COMES TO EXACT COVERAGE AT THIS TIME.
THE MAIN WEATHER STORY FOR THIS FORECAST PERIOD IS THE THREAT FOR
SEVERE WEATHER FRIDAY EVENING, WITH THAT THREAT POTENTIALLY
LINGERING INTO SATURDAY. TO GO ALONGSIDE THIS SEVERE WEATHER THREAT,
VERY HEAVY RAINFALL IS LIKELY, PARTICULARLY IN OUR NW COUNTIES
THROUGH SATURDAY AFTERNOON. FORECAST RAINFALL AMOUNTS ALREADY RANGE
BETWEEN 2-4 INCHES, WITH HEAVIER AMOUNTS CERTAINLY POSSIBLE WITH
CONVECTIVE BANDING.
RAIN CHANCES SHOULD BEGIN TO INCREASE BY THURSDAY NIGHT, WITH THINGS
REALLY GETTING UNDERWAY BY FRIDAY MORNING AS THE STALLED FRONTAL
BOUNDARY TAKES A MORE SW/NE ORIENTATION. WHILE MOST OF THE SEVERE
WEATHER PARAMETERS LOOK RELATIVELY GOOD FOR THIS TIME OF THE YEAR,
THE LINGERING QUESTION HERE IS INSTABILITY. GIVEN THE WIDESPREAD
RAIN AND CLOUD COVER, WE MAY NOT HAVE ENOUGH TIME TO DESTABILIZE IN
THESE AREAS CLOSEST TO THE FRONT. EVEN A LOT OF THE GUIDANCE
SUGGESTS INSTABILITY SUPPRESSION FROM THE HEAVY RAINFALL THROUGH
FRIDAY NIGHT.
FROM PURELY A SEVERE WEATHER STANDPOINT, SATURDAY AFTERNOON MIGHT BE
OUR BEST CHANCE FOR AN ORGANIZED SEVERE STORM OR TWO. A LOT OF THE
MORNING GUIDANCES PUTS THE COLD FRONT ALONG OR NEAR I-65 BY THE
EARLY AFTERNOON HOURS. THIS WOULD AT LEAST ALLOW FOR A FEW HOUR
WINDOW FOR INSTABILITY TO INCREASE IN OUR SE COUNTIES AS THE COLD
FRONT CONTINUES TO MOVE EAST. WHILE THE REGION IS CURRENTLY NOT
UNDER ANY KIND OF OUTLOOK FROM THE SPC, I WOULD NOT BE SHOCKED AT
ALL TO SEE SOMETHING GET INTRODUCED FOR THE DAY 3 PERIOD OVERNIGHT
TONIGHT. FOR BOTH FRIDAY AND SATURDAY, THE ENVIRONMENT LOOKS MOST
CONDUCIVE FOR DAMAGING WINDS AND TORNADOES, WITH THE THREAT FOR
LARGE HAIL BEING MORE SECONDARY.
STRONG COLD AIR ADVECTION WILL WORK IN BEHIND THIS FRONT, WITH
TEMPERATURES QUICKLY DROPPING INTO SATURDAY NIGHT. FROM HERE,
TEMPERATURES ARE EXPECTED TO REMAIN BELOW AVERAGE THROUGH TUESDAY,
BEFORE WARMING BACK TO A MORE SEASONABLE FEEL BY THE MIDDLE OF NEXT
WEEK.

AVIATION
(18Z TAFS)
ISSUED AT 1133 AM CST WED JAN 7 2026
CONDITIONS WILL GENERALLY REMAIN IN VFR CATEGORY FOR THE REMAINDER
OF THE AFTERNOON, BEFORE LOW-LEVEL CLOUDS AND REDUCED VIS WORK BACK
IN OVERNIGHT. MOST TERMINALS WILL SEE MVFR/IFR CIGS AND VIS
THROUGH 08/16Z, WITH A FEW TERMINALS DROPPING INTO LIFR CATEGORY
FOR VIS AND CIGS AS WELL. MIXING WILL BE SLOW AGAIN TOMORROW
MORNING, WITH MVFR CONDITIONS POTENTIALLY LINGERING TO 08/18Z.

FIRE WEATHER
WIDESPREAD RAINFALL IS EXPECTED THROUGH SATURDAY, WHICH WILL
POTENTIALLY AID IN REDUCING DROUGHT CONDITIONS ACROSS THE REGION.
GIVEN THE UPCOMING WIDESPREAD RAINFALL, FIRE WEATHER CONCERNS WILL
REMAIN LITTLE TO NONE FOR MUCH OF THE NEXT SEVEN DAYS.
