So what’s the deal with the storms this week moving from EAST to WEST? Isn’t that backward?
Alabama and Tennessee typically see weather ‘systems’ move the other way, west-to-east, because of the westerlies: the usual upper-air wind flow over the Continental United States.
Lately, a strong ridge over the northeastern United States and a series of upper-air lows near the Gulf Coast have reversed that flow giving us more of an easterly wind throughout the atmosphere. That breeze pushes the storms along westward from where they develop!
This changes back to a more normal west/northwest flow by the weekend, and that could mean some stormy weather! See more here on WHNT.com!
