Here is 850mb forecast

Thats indicating winds speeds of 50-60 kts at 850mb, thats not to far above the surface by the time that mixes down thats indicating wind speeds of 35-40 mph
Look at the dry air being pulled up into MO from the Desert SW just gives an idea of how strong the surface low is forecast to be.
500mb just gives a perspective on the strength of the trough

This is still 100+ Hours out so this forecast is far from any guarantee, however it is becoming apparent a major winter storm will impact somewhere in the plains this weekend, and while it currently looks like NE will be impacted severely there is still much that could change based on the exact strength and track of the system. Stay Tuned.
