STERLING, Colo. -- Back in Virginia, you've had many cool, clammy days recently.

About a week ago, the jet stream buckled northward near the West Coast, southward in the east, and a huge mass of Canadian air flooded the eastern two-thirds of the United States.

A northwesterly wind flow has set up from the Rockies eastward, bringing cold fronts southeastward while shoving out most of the warmth and moisture that typically are increasing this time of year.

That pattern will be undergoing some changes as the jet stream begins to buckle southward across the western states. That will lift warmth and moisture northward back into the nation's midsection.

A strong low-pressure system may develop near Colorado by Thursday, increasing the wind dynamics and pulling even more Gulf of Mexico juice through the Plains and Mississippi River Valley.

A series of severe weather outbreaks may occur in the Plains, especially from Thursday through the weekend. That is what we are out here to experience. You can read about what we end up catching on my weather blog.

For Virginia, things will be slower to change. The jet stream dip from Canada may hang near or over you several more days. Cooler than normal weather with occasional periods of wetness will be likely to continue.
