Severe Weather Coming... Could be Nasty! More on Winter

October 10, 2012; 8:55 AM ET


The big story will be the severe weather developing Friday and spreading northeast and east Saturday. If you notice on the map, I pulled the trigger on the severity of the storms Saturday thinking that the left front quad of the jet, high dew point and sufficient shear will be in place for damaging winds and tornadoes across the Midwest. The models are impressive in regards to the severe weather parameters coming together for a significant outbreak of severe weather Saturday.

Storms should initially develop along the dry line in western Kansas to western Texas Friday then spread northeast. The dynamics on Saturday will be the big driver in the development of supercell storms with the potential for moderate size tornadoes across Iowa and Missouri. If the storms hold together, they could spread into Illinois during the night.

Also below is a gif image of the snowfall for years with a neutral ENSO with a cold PDO/warm AMO. Interesting to see the Northeast seems to be the snowy area during these years.
