Heaviest Rain Moving East – Clear By This Evening


It has been a dreary day across the Tennessee Valley so far, with a mostly cloudy sky, as scattered showers have been making their way across the region.  The heaviest rain continues to shift east and is located in extreme Northeast Alabama and will be moving into northwest Georgia within the hour.  Patchy light showers/sprinkles are lingering behind the heaviest rain and still extend just west of I-65. Below is a radar image as of 12:30 pm.

Rainfall totals have mostly ranged between 1/2 to 1 inch, as expected.  Clouds and patchy showers will linger throughout much of the afternoon east of I-65, with clearing and some sunshine possible west of I-65. Below is a visible satellite image showing the clearing line (back edge of clouds) right on the doorstep of Northwest Alabama.

There is also a sharp dewpoint gradient coinciding with the clearing line as drier air will be moving in, along with the colder air. The dewpoint in Memphis is currently 28°, whereas in Huntsville it’s 50°.  Check out the regional dewpoints below.

High temperatures today occurred this morning and were mostly in the mid 60s before the cold front moved through. Actually many reached their high temperature for the day before sunrise. As much colder and drier air continues to filter into the Tennessee Valley, don’t expect a warm up today, even if the sun peaks out.  Temperatures will slowly cool into the 40s and low 50s this afternoon.  Below are the 12:00 pm temperatures across the area.

The combination of dry and much colder air moving in, with a clear sky, will aid temperatures in cooling into the upper 20s and low 30s tonight.  A northerly breeze between 5-10 mph will persist overnight, meaning wind chills could be in the low 20s tomorrow morning. You’ll need to bundle up as you head to school or work tomorrow morning.  Unseasonably cool weather will continue throughout much of the work week.
