KEY MESSAGES

Updated at 405 AM CST Mon Nov 2 2026 - Medium to high chances (50-95%) for showers and a few thunderstorms will move in Tuesday afternoon through Wednesday evening as another front moves through the region.

- There is a Marginal Risk for for flash flooding across the Tennessee Valley Tuesday night through Wednesday.

NEAR TERM

(Rest of Today and Tonight) Issued at 1016 AM CST Mon Nov 2 2026

The weather today will remain dry and warm which will be a nice change after the wet day that we had on Sunday. We will briefly be under mid-level shortwave ridging during the near term period with sfc high pressure centered off the NJ coastline. This will allow for breezy, southeasterly winds today on the west side of the sfc ridge as the gradient begins to tighten with the approach of our next weather system from the west. Wind speeds will come up to 10-15 mph with gusts near 20 mph (locally higher across the higher elevations of NE AL) this afternoon. Highs top out above normal in the low to mid 70s and with plenty of moisture in place at the surface (dewpoints in the 50s), lows only expected to drop into the mid to upper 50s tonight.

SHORT TERM

(Tuesday through Wednesday Night) Issued at 1016 AM CST Mon Nov 2 2026

The main focus for this week will be during the short term period as a trough swings eastward from the Central Plains to the Great Lakes region Tuesday and Wednesday. The trough will continue to dig southward as a potent shortwave rotates through the base of the trough over AR/LA/TX Tuesday afternoon into Wednesday. This will bring a sfc cold front through the area Tuesday evening into Wednesday which will be the main driver for increasing rain and thunderstorm chances midweek. Conditions are expected to remain mostly dry throughout the day on Tuesday with increasing cloud cover ahead of the trough and breezy, southwest winds with gusts of 20-30 mph. The front approaches Tuesday evening with some isolated showers and storms moving through our western zones ahead of the main front during the time. As the main band of frontal precipitation moves through, all areas will see 90-100 percent chances for rainfall Tuesday night into Wednesday. This will be a relatively slow moving frontal boundary and therefore, our concerns for flash flooding start to increase, especially after the amount of rain some areas of N AL received on Sunday. Most areas will see an additional 1-2 inches of rainfall with locally higher amounts of 3-4 inches which on top of the 3-5 inches received yesterday across NW AL, this could create some additional flooding issues. Currently, we are in a Marginal Risk for Excessive Rainfall from WPC with this system with just the far northwestern tip of Lauderdale County in a Slight Risk. Amongst the CAMs the timing of the entrance of main band of precip is still slightly varying but within the window of 10p-3a looks like the best estimate for entrance into NW AL with exiting NE AL by 6 PM Wednesday. There will be limited instability with the timing of the frontal passage with best chances for thunder being on Wednesday afternoon east of I-65 as the front works its way out of north Alabama.

LONG TERM

(Thursday through Sunday) Issued at 933 PM CST Sun Nov 1 2026

Extended range model guidance suggests that a weak low-level ridge will build northeastward into the local forecast area on Thursday, in the wake of a departing surface trough and axis of rain/thunderstorms. This (along with unamplified/westerly flow aloft of 35-45 knots) will support dry conditions, with overnight lows falling into the l-m 50s Thursday morning, followed by afternoon highs in the l-m 70s. On Thursday night, large scale ascent will strengthen considerably as a mid-level wave digs east- southeastward into the TN Valley in the flow around an upper low across the Great Lakes. Although the tropospheric column will be far too dry to support any risk for precipitation, a minor increase in cloud cover aloft should accompany the passage of this system. At the surface, a reinforcing cold front will spread southeastward in conjunction with the shortwave trough, with light northerly winds in the low-levels (beneath NW flow aloft) expected to result in a continuation of dry weather from Friday- Saturday night. Early morning lows in the m30s-l40s can be expected on both Saturday/Sunday, with afternoon highs in the l-m 60s. Low chances for rain may return to parts of the region by Sunday afternoon, either as a result of a weakening clipper system diving into the Mid-MS Valley or a lower- latitude disturbance shifting eastward along the northwest Gulf Coast. However, due to vastly different model solutions at this time range, we will keep POPs in the 10-20% range.

AVIATION

(18Z TAFS) Issued at 1041 AM CST Mon Nov 2 2026

VFR conditions will continue through the TAF period. The main weather concern is gusty southeasterly winds with gusts up to 18 knots this afternoon and then increasing to 20-25 knots tomorrow afternoon. Cloud cover will gradually increase from west to east during the day tomorrow with a low chance of MVFR ceilings. For now, kept it SCT and VFR, but will need to be something to keep an eye on in later forecasts.
