KEY MESSAGES

Updated at 205 PM CDT Sat Oct 10 2026

- The remnants of Isaias will continue to progress over the Tennessee Valley today, bringing medium chances for gusty winds up to 40-50 mph.

- A Wind Advisory is in effect for all of north Alabama and southern middle Tennessee through 7 PM this evening.

NEAR TERM

(Tonight) Issued at 205 PM CDT Sat Oct 10 2026

Light to at times moderate showers continue over portions of the area this afternoon. With low rainfall rates and confidence dropping in any flooding concerns, we decided to cancel the Flood Watch earlier today. In addition, with continued cloud cover over the local area and a warm front draped over central Georgia, expecting any storms to be concentrated well to our east in the warm sector and towards the east coast. Hi-Res guidance tends to agree with this thinking as well. However, even with the storm potential being very low for our area, wrap around showers from what's left of Isaias will keep low to medium chances of showers in the forecast through tonight. Chances then taper out through Sunday morning.

As for winds, these have been a bit lackluster so far this afternoon due to a relaxing pressure gradient. Observed gusts over the local area peaked between 30-40 mph at best a few hours ago (prompting us to downgrade the High Wind Warning to a Wind Advisory), but these have since further decreased. Wind gusts generally range between 20-30 mph at most at the moment, which is below even Wind Advisory criteria. We will be monitoring this over the next few hours to see if we should cancel the Wind Advisory early. For now, it remains in effect for all of north Alabama and southern middle Tennessee until 7 PM this evening.

SHORT TERM

(Sunday through Monday) Issued at 912 AM CDT Sat Oct 10 2026

With what's left of Isaias (that has/is merging into the upper level flow/trough) lifting to the northeast on Sunday, expect perhaps some lingering showers (low chances, 10-30%) especially for NE AL and portions of southern middle TN. However, by Sunday evening, dry weather will take hold as upper level ridging moves into the region and this will persist through at least Monday. While some wind gusts to around 20-25 mph may persist through much of the day on Sunday, winds really drop off into early next week. With upper ridging and high pressure over the South by Monday, temperatures increase from the 70s this weekend into the mid to upper 80s on Monday.

LONG TERM

(Monday night through Friday) Issued at 1102 PM CDT Fri Oct 9 2026

The upper ridging is expected to strengthen over the southeast Monday into the middle of next week. The sunny skies and building upper level winds will make for a very warm conditions with highs climbing back into the mid to upper 80s and lows in the lower 60s.

An upper level low and associated longwave trough axis makes some slight progress pushing east into the upper ridge over the area towards the end of the week/weekend. However, over much of the area the surface and upper ridge remain stout. However, enough forcing aloft and moisture convergence does setup over much of Tennessee to produce some precipitation over that area. Our southern middle Tennessee counties could see some low end precipitation chances, but consistency is too low to include at this time. Most guidance does push a dry cold front through the area Friday or Friday night. This will bring cooler weather to to the area that is more seasonable into the weekend.

AVIATION

(18Z TAFS) Issued at 1245 PM CDT Sat Oct 10 2026

MVFR to IFR conditions were observed at issuance, along with light showers for both terminals. Medium to high chances of showers will continue through this afternoon, then decrease to low to medium tonight (20-50%) from wrap around showers from the remnants of Isaias. Chances then diminish through early Sunday morning. Expect MVFR to IFR CIGs and lower VIS to persist through tonight, with the potential for improvement back to VFR Sunday afternoon. Winds will remain elevated, but gradually decrease through the period. Easterly winds around 10-20 knots with gusts up to 30-35 knots this afternoon will slowly decrease and shift to be out of the southwest by Sunday morning. Expect sustained winds between 10-15 knots and gusts up to 15-20 knots through the morning on Sunday.
