      Disruptive Storms Forecast for Northwest & Southeast U.S.
      Two stalled out systems will bring disruptive weather to opposite ends of the country today. 

      The first system is a stationary front over the northern Rockies. Warm air streaming in from the southwest and a jet stream will allow thunderstorms to form this afternoon and evening. 

      The Storm Prediction Center has a Slight Risk  in effect over southeastern Idaho, eastern Montana, and northwestern Wyoming. Cities include Pocatello, Idaho, Jackson, Wyo., and Billings, Great Falls, and Glasgow, Montana. The main threats will be sporadic damaging winds but some of the stronger supercells could produce large hail. 

      Across the Southeast, a slow moving low pressure system will produce extensive rain and thunderstorm activity from Mississippi to South Carolina and Florida. While a few of these storms may become severe, the primary threat will be flash flooding. Flash Flood Watches are in place for central and southeastern Alabama, southwestern Georgia, and the Florida Peninsula.

      Later tonight and Monday, heavy rain will surge northward toward North Carolina and western Virginia where additional watches are in place. Two to 6 inches will be possible with localized amounts of 8 to 10 inches today and Monday. 

      Remember, if you approach a flooded roadway, it is best to “Turn Around, Don’t Drown!”

      Make sure to know the difference between a watch and a warning should they become issued. A “watch” means that conditions are favorable for severe weather to occur and to be on alert for any rapidly changing conditions. A “warning” means that severe weather is imminent, and you should act fast to remain safe.
