More on the Tornadoes, Blizzard and TS Karen

October 3, 2013; 10:02 AM ET

Commentary

Nothing much has changed in regards to the severe weather across the Midwest into the Ohio Valley. Friday will be a nasty day across Iowa into Kansas with the potential for tornadoes. I think Iowa will get the bulk of the tornadoes due to the low-level jet and the quadrant of the jet aloft. Storms should form along the warm front in the afternoon and race northeast during the evening and night hours. I remain concerned for large tornadoes that can be on the ground for many miles.

Tropical Storm Karen will hit the Gulf Coast near Mobile late Saturday and move into the Southeast on Sunday. Karen could briefly become a hurricane, but once Karen nears the coast, shear should weaken the system back down to a tropical storm. It should hit the coast with tropical storm-force winds and heavy rains. I do think the heavy rains and flash flooding would be the main impacts with some coastal flooding along the western Florida beaches. Karen will track just east of the southern Appalachians to hit the western Carolinas with heavy rains Sunday night into Monday then Virginia Monday night.

Up the snow in Wyoming, South Dakota and western Nebraska for Friday into Saturday. I think the combination of wind and snow will create near-blizzard conditions and very poor travel.
