DISCUSSION
ISSUED AT 300 PM CST SAT JAN 10 2026
TONIGHT THROUGH MONDAY NIGHT: MUCH DRIER AND COOLER AIR IS
ADVECTING INTO THE FORECAST AREA THIS AFTERNOON, BUT THE MORE
PROMINENT COLD ADVECTION WILL TAKE PLACE SUNDAY WHEN A POLAR
STREAM TROUGH, CURRENTLY OVER THE UPPER MIDWEST, DIGS SOUTHWARD
INTO THE OH/TN VALLEY REGION. THIS THERMAL TROUGH WILL SUPPORT
TEMPERATURE READINGS THAT ARE MUCH MORE SEASONABLE FOR THIS TIME
OF YEAR. IN FACT, TEMPERATURES WILL ACTUALLY BE RUNNING A BIT
BELOW NORMAL AS WE FINISH UP THE WEEKEND AND GO INTO EARLY NEXT
WEEK.
TUESDAY THROUGH THE REMAINDER OF NEXT WEEK: AFTER A SLIGHT WARM-
UP FOR TUE-WED, IT CONTINUES TO LOOK LIKE WE WILL SEE A MORE
SIGNIFICANT SURGE OF COLD AIR FOR LATE NEXT WEEK. MODELS STRONGLY
AGREE THAT THE EASTERN CONUS LONGWAVE TROUGH WILL BECOME MORE
AMPLIFIED LATE NEXT WEEK AS TWO POLAR STREAM TROUGHS DIG
SOUTHWARD, AND TEMPERATURES MAY FALL WELL BELOW FREEZING IN OUR
AREA. WE'LL HAVE MORE DETAILS ON THIS AS WE CONTINUE TO MONITOR
FOR ANY COLD/WINTER WEATHER THREATS AND GET CLOSER IN TIME. /EC/
