Flood Forecast

Heading into the weekend, the ingredients are lining up for a serious flash flood threat.

The slow-moving nature of these ingredients is key.

A sharp, expansive southern plunge of the jet stream will be slow to lumber out of the western U.S.

Ahead of that, a deep plume of moisture will be pumped northward from the Gulf of Mexico and Caribbean Sea.

Thanks to the slow-moving jet stream plunge, a waffling frontal system will be slow-moving as well, from the Ohio Valley to Texas, providing additional lift for rain and thunderstorms.

* a potent upper level storm system will move into the area
Friday with strong to severe thunderstorms developing by early
evening across portions of eastern Oklahoma and northwest
Arkansas. Thunderstorms will continue Friday night through
Saturday evening with locally heavy rainfall as a frontal
boundary slowly pushes southeast. 4 to 6 inches of rainfall
are expected across east-central Oklahoma and northwest
Arkansas with locally higher amounts approaching 10 inches.

* The heavy rainfall will likely lead to widespread and
potentially life threatening flash flooding. Several rivers
will likely go into moderate to major flood including the
Illinois River and Lee Creek at Van Buren. Beaver Lake Dam in
northwest Arkansas could begin to release water which would
impact areas downstream.
