Extremely Windy Conditions Expected
This Evening through Saturday Afternoon

 

A strong cold front will move across western and north central Nebraska Friday evening.  Very strong pressure rises in the wake of the frontal passage, will help drive strong winds tonight through Saturday afternoon.

Surface low pressure will strengthen over the northern Plains this afternoon, as the cold front dives south across the high Plains this evening and overnight. Strong high pressure will be building over the northern Rockies.  Thus a tight pressure gradient will help produce a prolonged period of gusty northwest winds across our region.

Below is an animation showing the pressure gradient forces that will drive these strong winds across much of western & north central Nebraska. Please click to view this animation in Windows Media Player.
