Stormy Night Across the Plains; Cold in the Mountain West

South Central Radar 092209

A line of thunderstorms is moving across the southern Plains and Mississippi River Valley this evening ahead of a cold front.  Severe thunderstorm watches are in effect across eastern Oklahoma and north central Texas.  The storms have produced high winds and severe hail in these areas already and will continue to do so for another hour or two.  You can see the thunderstorms from St. Louis, MO to Dallas, TX on the surface map:

Surface data centered on Wichita, KS valid 9:30 PM EDT on 9/21

You may have also noticed the area of blue on the radar in southern Colorado. That is indeed snow falling in the Rockies as cold weather moves through the area.  There are numerous freeze warnings in effect throughout the inter-mountain West as cold air drives south from Canada.  The chill should be short-lived within the mountains, although it may last a few days in the High Plains just east of the Rockies.  You can see the snowfall indicated on the surface map:
