Severe Storm- Flash Flood Risk For Metro Kansas City and Central States

The one instance of severe flash flood in southwestern Arkansas that has killed many is in the news- but virtually unreported is the almost nightly thunderstorms drenching parts of Kansas- Nebraska and Iowa.

Overnight NWS radar-indicated precipitation totals of more than 10-inches were indicated in western north-central Kansas northeast of Colby to near Phillipsburg.

Other areas in Nebraska from near North Platte south and eastward saw heavy rains overnight on top of up to 8-inch amounts Friday morning.

Flash-flood warnings are in effect in Iowa this morning as thunderstorms from Nebraska moved eastward.

Gulf coast-like humidity levels and warm temperatures today will again bring thunderstorms- possibly severe but certainly with torrential rains- in a Storm Prediction Center forecasted area from the Texas Panhandle across much of Kansas and Missouri- including Metro Kansas City- north into parts of Nebraska and Iowa.

Large hail- wind gusts 60 m.p.h. or greater and maybe an isolated tornado are the usual  severe suspects- with a heightened risk of deadly flash flooding just about anywhere in the Central States generally along and north of Interstate 70.

The "slight" severe risk continues over the Central States through Monday- according to the SPC.

The latest 5-Day precipitation total amount for our area is also not promising if you wanted drier weather.

This morning's scattered shower and thunderstorm activity in Metro Kansas City is just priming the pump as far as saturating already moist soils.

More showers and storms will form anytime after about 6 p.m. this evening- with off and on activity expected through Monday morning.

CSW will post any bad weather watches here later today.
