Up and down weather patternDecember 4th, 2012 at 12:00 pm by Greg Shoup under Weather
A fast shot of colder air will be moving through the Great Lakes region and bring a quick dose of cold air from the north. This cold air will be followed by move pacific air moving in from the west coast.
Another uncharacteristically warm pattern will set up across our area being driven by mild pacific air with several wet and warm weather systems moving across the Pacific west. This warmer and wet pattern will most likely hold through the weekend.
Colder wintery forecast
By early next week it looks like it could become rather winter like here as a strong system could once again over spread arctic cold air across our region. This pattern will be replaced again by pacific air which will moderate temperatures.
This colder pattern may also produce a winter storm across portions of the Midwest as a low pressure center will move across the buckled jet stream. This low may be able to feed into some Gulf moisture and produce snow for parts of the Midwest. This is still a developing situation and could change quite a bit over the next several days.
