KEY MESSAGES

- The coldest air this snap is ongoing, and well below normal temperatures ride into and thru the weekend. Temperatures finally return to more seasonable levels by the middle of next week. - Low end precipitation chances exist Thursday night and Saturday night into Sunday morning, but amounts and impacts remain negligible.

DISCUSSION

Issued at 115 AM CST Thu Dec 4 2025

More low clouds are on the way as our reinforcing cold shot makes its mostly dry passage. While some light echoes that show up on long pulse radar mode might produce a light snow flake or flurry along/north of I-64 as the nose of the air mass arrives this morning, amounts and chances are negligible. Another small chance of light pcpn occurs this evening, when a surge of overrunning moisture that is largely to our south clips our far southeast counties/CWA border area. While a flurry cannot be ruled out and the Builder produces a hint of -FZRA, amounts range from T-0.01" and chances of this occurring are less than 30 percent.

Another upper trof makes passage this weekend, bringing the next best chance of pcpn over its back half. We're mostly above freezing during this window of time, so it's all liquid save for a brief period across the north Saturday night. Amounts are negligibly light and pops remain scant, with the system's main impact being another punch of cold air that keeps temperatures well below normal right on thru the remainder of the weekend and the beginning of the new work week.

Finally some moderation occurs by the middle of next week as high pressure shifts east in the wake of that departed system, and return flow southerlies develop. 40s and 20s are followed by 50s and 30s or closer to seasonal norms.

AVIATION /18Z TAFS THROUGH 18Z FRIDAY/

Issued at 1114 AM CST Thu Dec 4 2025

Persistent low (IFR to low MVFR) clouds seem more likely than not to hang on for most of the rest of the day south of I-64. Poorer visibilities and lower ceilings are expected the closer you get to the KY/TN and MO/AR border through the next few hours as weak precip moves across western TN. There is some pressure from the west to clear out and places like CGI have the best chance today but the highest probability - through 06z or so is for the clouds to stick around.

Some improvement is possible early Friday morning but clearing may only serve to lead to ground fog. Better overall conditions seem plausible for Friday as the parent upper storm system slides slightly further east.
