NEAR TERM

(Tonight) Issued at 152 PM CDT Sun Oct 11 2026

There have been no changes to the previous forecast. The back edge of the thick low level cloud cover has now just pushed east of the Huntsville metro area. Temperatures to its west have climbed into the low to mid 70s and should warm another couple of degrees before sunset this evening. Further east, afternoon temperatures are holding in the mid to upper 60s.

Previous Discussion: The remnants of Isaias continue to push further off to the north and east with the bulk of the tropical moisture now across the Mid-Atlantic. Over the Tennessee Valley sits the base of an upper level trough with a pronounced low pressure system, as seen in water vapor imagery, spinning over TN/KY. Wrap around moisture to the south and west of the low continues to produce light rain/drizzle or low cloud cover. As the upper trough lifts to the northeast later today, clouds should gradually clear from west to east, with the back edge of the clouds already in NE MS as of 9am. Temperatures are forecast to warm up into the upper 70s along and west of I-65 and only the lower 70s further east where clouds linger a bit longer into the afternoon.

By tonight, clear skies and light winds will set up ideal radiational cooling conditions. Expect temperatures to fall into the low to mid 50s. Given the moist sfc conditions, tonight will be favorable for fog. While it is unclear how widespread the fog will be, if you do encounter any out driving, take it slow due to the reduced visibility.

SHORT TERM

(Monday through Wednesday Night) Issued at 913 AM CDT Sun Oct 11 2026

Upper level ridging will be the predominant feature as we start off the new week. With high pressure centered underneath the ridge, expect tranquil and warm conditions across the Tennessee Valley. Afternoon highs will top out in the upper 80s to lower 90s through mid week, which is around 10 degrees above climatological normals for this time of year. Overnight lows will fall into the upper 50s to lower 60s each night. The main concern during the short term period is how much dry air aloft mixes down to the surface. If increased mixing occurs this would set up a brief window for an elevated fire wx risk. However, winds are forecast to remain light and well below any fire wx criteria.

LONG TERM

(Thursday through Sunday) Issued at 913 AM CDT Sun Oct 11 2026

The upper level ridge will gradually break down during the long term forecast period bringing another taste of Fall-like weather by this weekend. Warm conditions will continue on Thursday as we once again see temperatures rise into the upper 80s to lower 90s. On Friday, a low pressure system drops down from Canada into the Great Lakes region with a cold front positioned to its south. Due to the lack of moisture associated with this front, no precip is expected as it passes through the local forecast area on Friday. However, an airmass change begins to occur with NW flow advecting in much cooler and drier conditions. We will start to feel this change Friday night as temperatures are forecast to drop into the upper 40s to lower 50s. This upcoming weekend will truly feel like Fall as temperatures warm only into the upper 60s to lower 70s with overnight lows in the low to mid 40s.

AVIATION

(00Z TAFS) Issued at 747 PM CDT Sun Oct 11 2026

Clear skies are in place at both terminals this evening and this will continue overnight. Winds as of 00Z are still at 4 knots at both KHSV and KMSL. However, would expect surface winds to become light or calm over the next few hours. Thus, a good setup for fog development (medium to high chance of being dense) will be in place. For this issuance lowered VSBYS down to MVFR after 6Z. Then reduced VSBYS to 2SM with a tempo group for now between 8Z and 12Z. VSBYS may need to be lowered either before or at next issuance time for this product. Expect VFR conditions to return again after 15Z on Monday. Wind from the west around 5 knots are expected during the day.
