The episode as NWS SLC wrote it up.
Patchy freezing rain was reported across the West Desert producing slick roads near the U.S. Army Dugway Proving Ground.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Salt Lake City, UT wrote its last area forecast discussion before the first event at Jan 9, 4:06 PM MST, 5 hours 54 minutes earlier.
Area Forecast Discussion National Weather Service Salt Lake City UT 406 PM MST Wed Jan 9 2019 .SYNOPSIS...A weak weather system will bring showers to northern Utah Thursday with high pressure dominating trough the end of the week. && .SHORT TERM (Through 00Z Saturday)...The highest impact items expected during the short-term forecast period will be the continued inversion over Northern Utah's valleys and a storm system moving through the northern half of the forecast area Thursday into Friday. Southwest flow aloft will continue to prevail ahead of an elongated upper level trough currently off the west coast will begin its onshore movement tonight. As the trough moves onshore, it begins to undergo a couple key influences...First, a jet max enters the ridge on the backside of the trough, building the ridge over the PacNW directly upstream of the trough. Second, a southern finger of the Polar Front Jet strengthens downstream of the upper level trough over the four corners region, amplifying the southern extent of the trough. These two factors cause the trough to stretch as it passes through the region, weakening the vertical motion associated with the trough. Despite the weak forcing, light precipitation should be experienced along much of the northern half of the forecast area associated with a thin band of synoptic lift and a surface cold frontal boundary. The low QPF precipitation should fall as light mountain snow with a rain/snow mix expected for many of the valleys. The warm layer also has the potential to cause freezing rain/drizzle in the western desert until the deeper extent of cold air moves through in the afternoon. The confidence of this is low ATTM, therefore, it was not included in the current forecast package. In regards to the inversions...The 12Z KSLC RAOB sounding indicates a strong inversion with the max subsidence layer based at 803mb/~2200ft AGL. This inversion is continuing to degrade the air quality over the northern Utah valleys this afternoon. The wind speeds have increased over the inversion with many weather stations above ~7 kft MSL reporting southerly winds gusting between 20-30 mph. These enhanced winds are expected to gradually weaken overnight. After frontal passage...High pressure and a relatively dry airmass is expected to build into the forecast area as the aforementioned ridge builds to our NW. Despite the weak cold air advection aloft after the trough's passage, the inversion is expected to remain in place through the week. .LONG TERM (After 00Z Saturday)...A large scale blocking pattern will remain in place at the beginning of the long term period, characterized by a highly amplified ridge centered across the northern Rockies. A weak shortwave trough expected to undercut the ridge and traverse the Desert Southwest late Saturday into Sunday, however any precip threat should remain well south and as such have maintained a dry forecast through the weekend. The medium range models are in agreement breaking down the mid level ridge early next week and bringing a series of shortwave troughs inland across the Interior West. Timing these waves is a bit problematic at this point, and as such have generally maintained chance PoPs for the latter portion of the long term period. Kept temperatures close to guidance through the long term period however developing inversions in the short term will ultimately dictate temperature trends over the weekend. && .AVIATION...Light winds will continue through the TAF period at KSLC with light west-northwest winds this afternoon giving way to the diurnal southeasterly shift between 02-03Z this evening. Northwest winds will develop again Thursday between 19-20Z. Ceilings will lower below crest level Thursday between 16-19Z with an approaching weak disturbance. A few light rain or snow showers are possible at the terminal Thursday afternoon. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None.
