9AM Photo, Star Valley Ranch, March 4 2015

It was a cold morning across all of Wyoming. Star Valley, while cold, was spared record breaking temperatures by insulating clouds much of the night.  They cleared around sunrise and allowed the Afton airport observation to dip to 6 below.  Following are the observed minimums across the valley this morning,

Star Valley Ranch             7
Alpine                               6
2 S Bedford                       5
Etna Elementary               4
Smoot                                3
Double L Ranch               -2
Thayne Elementary          -4
Afton Airport                   -6

Further east clouds dissipated early in the night and resulted in much colder, record breaking temperatures.
