Last Day of 2014-Cold!!!

As expected ideal conditions resulted in one of the coldest nights in Star Valley in almost 2 years. The last time it was as cold was on January 14 2013.

Typically the Auburn area is the coldest part of the valley  and this morning was no exception.  My truck thermometer dipped to -35 around sunrise.

And the nearby cattle were evidence of how cold it was.

The coldest reported in Western Wyoming  was Daniel with -48 followed by Bondurant which bottomed out at -42F.

Following is a list of observed minimums across Star Valley this morning:

Afton                     -33
Double L Ranch    -31
Smoot                    -26
Thayne ES             -25
Etna ES                  -24
Alpine                    -18
Star Valley Ranch  -16

Here is a map across the area where temperatures dipped below -25F

Minimums below -20F December 31 2014

How Cold Is It?

Subzero temperatures dominate most all of Wyoming this Tuesday Morning.  Following are minimums reported in Star Valley as of 8am.

Double L Ranch -27

Afton airport       -24

Bedford               -19

Smoot                  -18

Thayne ES           -18

Etna ES                -15

Star Valley Ranch  -6

Alpine                     -3

Because of east winds down the Snake River Canyon mixing the cold air, Alpine was about the only station not dropping much below zero, however the 10-15 mph east winds dropped the wind chills to about -20!

Coldest reported thus far in Western Wyoming has been at Bondurant with -38.

Following is a map of some of the coldest temperatures reported this morning.

Minimums less than -20F Tuesday December 30 2014

Sub Zero Temperatures on the Way

Subzero cold is on the way to much of western Wyoming including Star Valley. In the wake of the current storm, skies should clear late Friday into Saturday.  This will allow temperatures to plummet by Saturday morning. Below zero readings should be common with the typically coldest valley locations possibly to 10 below.

However a major adjustment to the jet stream pattern across the Pacific Ocean is expected to lead to even colder temperatures by next week. 

The following 500 mb charts graphically illustrate the expected change.

Noon Dec 25 2014

Noon Dec 27 2014

Noon Dec 29  2014

This large high pressure ridge off the west coast will allow very cold air to pour south from Canada into the Western States including western Wyoming.

By mid day Saturday the models depict the cold air over Canada heading south toward the western States.

By noon Monday  a cold polar high pressure is spreading the airmass south into the area.

By Tuesday night bitter cold has engulfed all of Wyoming and surrounding states

As of now it appears that by Wednesday morning if not before the mercury will dip to 10 to 20 below zero  in many areas of western Wyoming and possibly 30 below in the typically coldest locations.
