MID-MISSOURI - From blizzards to spring floods, severe thunderstorms to extreme heat and drought, we have seen it all here in Missouri this year. Which raises the question what's next?

We all remember the February 1st blizzard. We told viewers the Friday before to expect a foot of snow, if not more. Then we said to expect a hot and dry summer which also proved true.

Tony Lupo, Atmospheric Science Professor said, "Generally when you have La Niña conditions that continue from one year to the next. You have a hot summer and those hot summers continue to extend into the fall into Septemeber, October and even into November."

If this sounds familiar that's because this set up is exactly how fall played out last year. Out with the mild and dry conditions and in with the bitter cold and record breaking snowfall. Thanks all in part to La Niña.

"La Niña is the absense of warm water in the east tropical pacific," Lupo said, "when those waters warm we call that El Niño and then when those waters cool back down thats what we call La Niña."

So you may be asking how does La Niña affect our weather here in Mid-Missouri? These conditions impact the placement of the jet stream which influences the path of the storm track. So in a La Niña year you typically have Northwest flow over the continent. Our predictions for this winter are looking similar to last year. A typical Missouri winter sees around 20 inches of snow. Last year, we had a record breaking amount of 45.6 inches. This winter, we expecting to see colder than normal temperatures and above average snowfall, again.
