How Cold Was It?
Overnight cloud cover thinned/dissipated toward sunrise allowing a rapid temperature drop. In the Lower Salt River Valley clouds hung around longer and as a result minimums were only near zero. However, from about Thayne southward it cleared and was much colder. Following are the observed minimums in the valley this morning.
Auburn -17
Afton -13
Thayne ES -8
Osmond ES -8
Smoot -5
Etna ES -1
Star Valley Ranch 2
Alpine 3
Nearby it was:
Pixley south of Cokeville -21
Driggs ID -17
Cokeville -15
Jackson Airport -13
In other areas clouds were not a factor and as a result it was much colder.
Old Faithful -33
West Yellowstone -35
and the coldest was a -41 at the Peter Sink Site which is located just south of Logan Summit Utah west of Bear Lake. This high elevation sheltered site is typically one of the coldest around.
