KEY MESSAGES
- COLD AND DRY WEATHER WILL BE THE GENERAL RULE THROUGH TUESDAY
NIGHT.
- MILDER AND WETTER CONDITIONS ARE EXPECTED FOR LATE WEEK.
DISCUSSION
ISSUED AT 415 AM CST SUN JAN 18 2026
TODAY THROUGH TUESDAY NIGHT: POLAR FLOW INTO THE EASTERN CONUS
WILL MAINTAIN A STEADY SUPPLY OF COLD AIR FOR OUR FORECAST AREA.
COLD AND DRY CONDITIONS WILL BE THE GENERAL RULE WITH TEMPERATURES
AND WIND CHILL READINGS NOT QUITE MEETING "COLD WEATHER ADVISORY"
LEVELS.
WEDNESDAY THROUGH FRIDAY NIGHT: THE POLAR STREAM WILL RETREAT AT
LEAST TEMPORARILY NORTHWARD AS WE GO LATER INTO THE WEEK. A WARM
ADVECTION PATTERN WILL DEVELOP AS A RESULT, AND THIS WILL BRING AN
INCREASE IN SHOWER CHANCES AND TEMPERATURES. AS OF NOW, RAINFALL
TOTALS ARE NOT EXPECTED TO BE EXTRAORDINARY, AND INSTABILITY
SHOULD NOT SUPPORT MUCH IN THE WAY OF THUNDERSTORM ACTIVITY.
NEXT WEEKEND: WEATHER DETAILS ARE HIGHLY UNCERTAIN GIVEN THE MANY
DIFFERENT MODEL SOLUTIONS ON WHEN THE POLAR AIR WILL MAKE RETURN.
IT APPEARS WE'LL HAVE A STRONG TEMPERATURE GRADIENT ACROSS THE
AREA AND THIS WILL HELP TO MAINTAIN UNSETTLED WEATHER. NEXT
WEEKEND WILL BE A GOOD WINDOW OF TIME TO MONITOR FOR FORECAST
CHANGES. /EC/
