Helping Business Weather the Storm

Hazardous Weather Outlook for Wednesday, October 1, 2014

by WeatherOps, on Sep 30, 2014 4:09:59 PM

Severe thunderstorms are possible Wednesday for portions of the Missouri Valley and Central Plains. Strong to severe storms are possible for portions of the Central and Northern Plains. Heavy rain and general thunderstorms will be possible for Missouri and points south to the Arkansas/Oklahoma border.

Central Plains: A lead wave of low pressure will lift across the Central Plains on Wednesday ahead of a developing trough of low pressure over the Rockies. Moderate instability is expected to build to the north and east of a surface low over Kansas with a dryline extending down into Northwest Texas. Severe thunderstorms will be possible by early to mid-afternoon from eastern Nebraska/southern Iowa, down into portions of Kansas, and possibly as far south as western portions of Oklahoma. Impacts with the stronger storms will include large hail of up to 2.00” and winds gusting in excess of 55 mph. A tornado threat may also develop in close vicinity to the surface low and also with any severe storms that develop along the dryline.

Central/Northern Plains: Strong warm air advection should be ongoing on Wednesday from the Southern Plains into the Central Plains. Upper-level forcing ahead of the developing trough to the west will support isolated to scattered showers and strong thunderstorms from Northwest Texas into the Upper Midwest with a risk for hail up to 1.00” and winds gusting in excess of 45 mph.

Missouri & Oklahoma/Arkansas border: Heavy rain from thunderstorms on Wednesday across the Central U.S. will produce 1 to 2 inches of rain from Missouri and southward along the Oklahoma/Arkansas border.
