Helping Business Weather the Storm

Hazardous Weather Outlook for Wednesday, August 19, 2015

by WeatherOps, on Aug 18, 2015 9:55:02 AM

Strong to severe thunderstorms will be possible on Wednesday for the Mississippi Valley. Heavy rainfall with locally heavy rainfall expected for portions of Ontario.

Strong to severe thunderstorms are possible ahead of a cold front moving through the Mississippi Valley. Ongoing precipitation and weak to moderate wind shear will limit the possibility of severe thunderstorms. Moderate instability and lift associated with the cold front could support line segments of storms that will track southeastward. Damaging winds will be the primary hazard with these storms.

The surface low moving through the Northern Plains will continue to track northeastward and bring heavy rainfall to portions of Ontario. 1-2 inches of rain with locally higher amounts will be possible.
