Thar she blows!
The cold front is just upstream of Hat Island and we can now get a pretty good look at its strength in terms of the airmass change and post-frontal winds. The MesoWest analysis shows a 16F temperature contrast between Hat and Gunnison Islands.
The temperature at Gunnison Island dropped from about 43F to 28F with frontal passage, which was accompanied by a 55 mph wind gust. Post frontal winds, however, have subsided to about 25 mph sustained with gusts to just over 35.

It's a bit nastier along I-80 in the West Desert. DPG17 warmed to 48F and then observed an abrupt temperature drop to 28F with fropa. Impressive! Post-frontal winds are sustained 40 mph with gusts to over 45. This is blizzard strength for sure and it must be a mess and really lonely out there on I-80. I suspect the surge to 48F may have been fueled a bit by a clear slot that was evident in the satellite earlier this afternoon (mentioned at weather discussion).
It should be a spectacular cloud display as the front pushes into the Salt Lake Valley.
Keep in mind the "SLCBY" MesoWest site for 1-minute obs from the fropa. This site is located at the NWS.
