KEY MESSAGES
UPDATED AT 638 PM EST SUN JAN 4 2026
- PATCHY DENSE FOG IS POSSIBLE BETWEEN MIDNIGHT TONIGHT AND 10 AM
MONDAY, MAINLY ALONG AND SOUTH OF INTERSTATE 85.
- ABOVE AVERAGE TEMPERATURES (BY 10 TO 25 DEGREES) ARE EXPECTED
FOR THE WORKWEEK.
SHORT TERM
(THIS AFTERNOON THROUGH MONDAY)
ISSUED AT 106 PM EST SUN JAN 4 2026
THE FOG POTENTIAL TONIGHT & MONDAY MORNING:
THE PRIMARY VARIABLE TO MONITOR IN THE NEXT 24 HOURS IS THE
POTENTIAL FOR DENSE FOG BETWEEN MIDNIGHT TONIGHT AND 10 AM MONDAY.
FOG IS MOST PROBABLE ALONG AND SOUTH OF INTERSTATE 85, WERE THE BEST
COMBINATION OF LIGHT WINDS AND SURFACE MOISTURE SHOULD BE IN PLACE
TONIGHT. THE ELEVATED MOISTURE IN THIS REGION IS EVIDENT ON
SATELLITE THIS AFTERNOON DUE TO THE LINGERING LOW CLOUD COVER. THERE
IS A 40% CHANCE THAT A DENSE FOG ADVISORY WILL BE ISSUED FOR THIS
PART OF THE STATE OVERNIGHT. FOG IS UNLIKELY IN NORTHWEST GEORGIA,
WHERE LOWER SURFACE DEWPOINTS SUGGEST INSUFFICIENT MOISTURE
CONCENTRATIONS. THE PRIMARY FAIL POINT FOR THE FOG FORECAST
OVERNIGHT APPEARS TO BE THE DENSE CIRRUS STREAMING IN FROM THE
CENTRAL PLAINS. IF THESE CLOUDS REMAIN THICK OVERNIGHT, IT WILL
HINDER RADIATIONAL COOLING AND LIMIT THE FOG COVERAGE. RAPID WARMING
AND SUBSEQUENT BOUNDARY LAYER MIXING SHOULD BRING AN FOG RISK TO A
RAPID CONCLUSION MONDAY MORNING.
MILD WEATHER MONDAY:
MONDAY WILL BE THE FIRST DAY OF A SIGNIFICANT WARMING TREND THAT
WILL SEE TEMPERATURES RETURN TO THE 70S BY THE END OF THE WORKWEEK.
THE WARMING WON'T BE THIS INTENSE MONDAY AFTERNOON, BUT WIDESPREAD
AFTERNOON HIGHS IN THE MID 60S SHOULD OCCUR. TEMPERATURES OF THIS
LONG TERM
(TUESDAY MORNING THROUGH NEXT SATURDAY)
ISSUED AT 106 PM EST SUN JAN 4 2026
BROAD MID- TO UPPER-LEVEL RIDGING WILL BE IN PLACE AT THE START OF
THE LONG TERM (TUESDAY). A WEAK SHORTWAVE AND LOW PRESSURE SYSTEM
WILL BE TRAVELING EASTWARD ACROSS THE UPPER MIDWEST AND GREAT LAKES
REGION TUESDAY INTO WEDNESDAY LEADING TO MORE ZONAL FLOW ALOFT.
CLOUDS ARE LIKELY TO MAKE A RETURN ON TUESDAY ESPECIALLY ACROSS
NORTH GA AS SOUTHERLY TO SOUTHWESTERLY FLOW RETURNS. A LOW CHANCE
FOR A FEW LIGHT RAIN SHOWERS REMAINS POSSIBLE OVERNIGHT TUESDAY INTO
EARLY WEDNESDAY BUT UPPER-LEVEL SUPPORT IS LIKELY TO BE WEAK. THUS,
ANY RAINFALL LOOKS TO BE MINIMAL WITH AMOUNTS LESS THAN A TENTH OF
AN INCH. OVERALL, LATEST ENSEMBLE GUIDANCE REMAINS LESS EXCITED
ABOUT THIS POTENTIAL AND ANY MEANINGFUL RAINFALL IS LIKELY TO HOLD
OFF UNTIL LATER IN THE WEEK.
MID- TO UPPER-LEVEL RIDGING GRADUALLY BECOMES MORE AMPLIFIED OVER
THE COURSE OF THE WEEK AS TROUGHING ACROSS THE SOUTHWEST US
DEVELOPS. THIS WILL LEAD TO GRADUALLY WARMING TEMPERATURES WITH WELL
ABOVE NORMAL TEMPERATURES (10-20 DEG) BY LATE IN THE WEEK.
ADDITIONALLY, MUCH NEEDED RAINFALL LOOKS TO MAKE A RETURN BETWEEN
THURSDAY AND SATURDAY, AS A DIGGING TROUGH AND LOW PRESSURE SYSTEM
TRACK ACROSS THE PLAINS EVENTUALLY LIFTING NORTHEAST. LATEST
GUIDANCE CONTINUES TO SUGGEST MAINTAINING A WATCHFUL EYE AS THIS
SYSTEM TRACKS EASTWARD. RIGHT NOW, ONE OF THE UNCERTAINTIES WILL BE
HOW MUCH INSTABILITY (STORM FUEL), IF ANY, WILL BE AVAILABLE AS
THE SYSTEM MOVES THROUGH. WE ARE STILL AT A BIRDS EYE LEVEL THUS
DETAILS REMAIN UNCLEAR AT THIS TIME BUT IT'S WORTH NOTING THAT THE
POTENTIAL IS THERE.
