More Snow for the Midwest...Pattern to Remain Wintry!

January 13, 2012; 10:03 AM ET


The map below is my take on the next snowstorm. The West should get hit hard by snow and cold over the weekend, and all that snow and cold will head into the Midwest and Great Lakes early next week. Places that had snow in Illinois to Michigan will get hit again with snow Monday into Tuesday. Using Chicago as the center of the snow, I see 3-6 inches for that area Monday night. Behind, cold weather will once again plunge across the eastern part of the country with another round of heavy lake snow.

A lot of you have been talking about the pattern and the change in the pattern. We continue to see a decline in the SOI values, a negative PNA, a bumpy NAO and negative AO. Understand that pattern changes don't happen overnight, and for the whole Northern Hemisphere jet stream to change its wavelength, it takes time. So given this, let me give you my thoughts on January into March.

1. The last half of January will be a bumpy one with cold dominating but also spells of warm weather.

2. Snow will be centered over in two locations. The Northwest and the Midwest/western Great Lakes. Some snow will sneak into the Northeast north of I-90.

3. In February, the cold should become more widespread across the northern Plains into the Northeast.

4. February into March should be stormier with the potential for a major snowstorm along the East coast. Midwest and Great Lakes will continue to see the bulk of the snow.

5. March will probably end up on the colder side across the eastern half of the country.

6. Severe weather across the South and southern Plains may become more widespread February and March. It should not be on the magnitude that we saw last year.

That's my ideas. Enjoy!
