Updated at 156 AM EST Thu Nov 5 2026

DISCUSSION

Issued at 156 AM EST Thu Nov 5 2026

Currently, a closed low is located to our north with a frontal boundary along western portions of the area. Ahead of the cold front, showers and storms have provided widespread rain to the area. Fog has already been developing, and a Dense Fog Advisory has been issued for part of the area. The front will gradually move through the area during the day with a few additional showers possible. Otherwise, gradually clearing conditions are expected with northwesterly winds ahead of high pressure producing seasonally cooler temperatures by Friday morning. As the closed low to the north approaches the area, height falls will help to reduce highs more into the 60s during the day. By Saturday, high pressure will be centered to our west with CAA having pushed highs down into the 50s for most. Saturday night, high pressure will become more directly centered over the region, leading to stronger subsidence and radiational cooling with overnight lows dropping well into the 30s. This will likely be the first frost for many places, along with a first freeze for some as well.

Surface high pressure will remain in place on Sunday with varying indications of a shortwave moving in from the west. Continued subsidence and drier air will keep the region dry and mostly clear, but temperatures will remain seasonally cooler through the day. After the shortwave moves east, subtle height rises with quasi-zonal flow will allow for a slight warming trend into the next week. Overall, highs should be in the 60s for most with morning lows in the 30s and lower 40s.

AVIATION

(06Z TAFS) Issued at 1217 AM EST Thu Nov 5 2026

Deteriorating aviation conditions are already occurring at CHA and TYS and are expected to worsen more through the night due to recent rainfall. Reductions to LIFR, which have already been seen a few times, are likely at both by early morning. TRI has remained VFR and looks less likely to reach below MVFR. However, trends will be watched at all sites. Additional rain showers in the morning could lead to more reductions at TRI. The sites will slowly improve back to VFR through the day, taking the longest at TRI. Winds will generally be from the southwesterly to westerly direction.
