DISCUSSION
(TODAY THROUGH NEXT TUESDAY)
ISSUED AT 154 AM CST WED JAN 7 2026
ANOTHER MORNING WITH AREAS OF DENSE FOG. DENSE FOG ADVISORY WILL
REMAIN INTACT THROUGH 15Z. HAVE BEEN WATCHING FOR VISIBILITY DROPS
DOWN AT TROY AND EUFAULA, FOR POSSIBLE DFA AREA EXTENSION. SO FAR
EARLY THIS MORNING, THEY DON'T (YET) REACH CRITERIA.
MODEL GUIDANCE CONTINUES TO PAINT A WARMER THAN NORMAL WEATHER
PATTERN FOR CENTRAL ALABAMA THROUGH THE END OF THIS FIRST WORK
WEEK OF 2026, WITH A FLAT UPPER LEVEL RIDGE OVER THE GULF COAST.
NEXT WEATHER MAKER STILL LOOKS TO COME ON FRIDAY, AS A SERIES OF
SHORTWAVE TROUGHS EJECT OUT OF THE SOUTHWEST INTO THE OHIO VALLEY.
THE FIRST SUCH SHORTWAVE ACTUALLY SCOOTS TO ALABAMA'S NORTH ON
THURSDAY, AND GETS SHEARED OUT IN THE PROCESS. THERE'S AN OUTSIDE
CHANCE OF A SHOWER OR TWO ASSOCIATED WITH THIS FEATURE. BUT
CURRENT MODEL GUIDANCE SUGGESTS THE RAIN WILL WAIT UNTIL THURSDAY
NIGHT AND (MORESO) FRIDAY, WHEN THE ASSOCIATED SURFACE COLD FRONT
STARTS TO PUSH INTO THE REGION.
THE FRONT IS FORECAST TO BRIEFLY SLOW DOWN OR STALL AS IT
APPROACHES NORTHWEST ALABAMA ON FRIDAY, BEFORE BEING KICKED ALL
THE WAY THROUGH BY THE NEXT SHORTWAVE ON SATURDAY. THIS
SLOWING/STALL WILL LIKELY LEAD TO SOME SIGNIFICANT RAIN TOTALS IN
THE NORTHWEST PART OF OUR FORECAST AREA, ON THE ORDER OF 2 INCHES
OR MORE. RAINFALL AMOUNTS SHOULD GENERALLY DECREASE AS YOU HEAD
MORE SOUTH AND EAST, BUT ALL PARTS OF CENTRAL ALABAMA ARE LIKELY
TO GET AT LEAST A HALF INCH TO ONE INCH OF RAIN BEFORE IT COMES TO
AN END LATE SATURDAY.
WILL NEED TO CONTINUE TO WATCH THE SEVERE WEATHER RISK FOR FRIDAY,
ESPECIALLY FRIDAY AFTERNOON AND EVENING. THE UNUSUALLY WARM AND
MOIST LOW LEVEL AIRMASS WILL PROVIDE INSTABILITY, AND LARGE SCALE
LIFT ASSOCIATED WITH THE FRONT SHOULD BE SUFFICIENT TO PRODUCE
THUNDERSTORMS IN THIS TIME FRAME. ONE PARTICULAR FEATURE TO KEEP
AN EYE ON IS A LOW LEVEL JET THAT BOTH THE GFS AND ECMWF FORECAST
TO DEVELOP FRIDAY EVENING AND PUNCH RIGHT ACROSS THE MIDDLE OF THE
STATE. THIS JET COULD PROVIDE AN ADDITIONAL SOURCE OF BOTH LOW
LEVEL SHEAR AND CONVERGENCE, WHICH WOULD AID IN SEVERE
THUNDERSTORM POTENTIAL (GIVEN THE INSTABILITY REMAINS HIGH ENOUGH
AFTER DARK).
COLD AIR SPILLS BACK INTO CENTRAL ALABAMA SATURDAY NIGHT AND
SUNDAY AS THE FRONT DEPARTS TO OUR WEST. DRY CONDITIONS AND
SEASONABLE TO BELOW NORMAL TEMPERATURES ARE INDICATED FOR THE
END OF THE FORECAST PERIOD EARLY NEXT WEEK.

(12Z TAFS)
ISSUED AT 524 AM CST WED JAN 7 2026
A MIXTURE OF LOW LEVEL STRATUS AND DENSE FOG HAS RESULTED IN
IFR/LIFR CONDITIONS ACROSS ALL TERMINALS. VISIBILITIES ARE
EXPECTED TO IMPROVE BY 15Z. CEILINGS WILL SLOWLY LIFT THROUGH THE
MORNING WITH MVFR RETURNING BY LATE MORNING, FOLLOWED BY VFR EARLY
THIS AFTERNOON. LOW LEVEL STRATUS MOVES BACK IN AFTER MIDNIGHT
TONIGHT. MODEL TIME HEIGHTS AND FORECAST SOUNDINGS HINT AT MORE OF
A LOW LEVEL STRATUS EVENT FOR THURSDAY MORNING BUT AS WE HAVE SEEN
THE LAST COUPLE OF MORNINGS, IT WILL LIKELY A MIXTURE OF BOTH.
