The Weather Authority is continuing to monitor a disturbance tracking through the region that will bring beneficial rain and strong winds through early Tuesday.
While parts of the Deep South saw severe weather, the thunderstorm activity and severe weather threat were limited for our area. With the warm front remaining further south, it kept the unstable airmass well to the south as well. Dewpoints remained in the upper 50s, compared to further south where tropical moisture was in place allowing dewpoints to surge into the upper 60s. Finally, while we did have wind shear in place, change in wind direction, and/or speed with height, we did not have the instability in place to support storm development.
Heading into the rest of the night, the bulk of rain will continue to shift east over the region. It is forecast to slowly track through the area, increasing the potential localized heavy rainfall. The best chance for moderate to heavy rain to occur will be across parts of Northeast Alabama.
Rain totals across the Tennessee Valley will range from one to two inches by early Tuesday morning. Isolated flash flooding will be possible in areas that see training heavy rain.
The main impact this system will bring to the area is strong winds, sustained between 25-30 mph. Wind gusts are forecast to reach upwards of 45-50 mph, especially in the higher terrain. The strongest winds will occur after midnight during the frontal passage. A Wind Advisory will remain in effect through 6 am Tuesday morning.
Behind this cold front, cooler and drier air will filter into the Southeast region. This will lead to sunshine and highs in the 50s by Thanksgiving.
