|1800 UTC 9 Feb – 1800 UTC 11 Feb 2014 GFS analysis of 925 mb wind (vectors) and integrated water vapor (mm, color contours with warmer colors indicating higher values).|
It certainly looks like the upper-elevation mountains of southern Idaho and western Wyoming are going to get another pasting, as indicated by the GFS accumulated precipitation through Saturday morning.
As you might deduce from the plot above, the mountains of northern Utah sit on the southern periphery of the heaviest 4-day accumulated precipitation in the current model forecasts. Nevertheless, this does look like another significant event for the northern Wasatch and the Bear River Range (although not as big as the previous storm), with the Cottonwoods and southern Wasatch likely seeing their most significant precipitation late Wednesday and Thursday when the AR dips southward.
This is also going to be another warm event thanks to the Hawaiian connection. Direct output from the 12-km NAM (below) suggests rising ridge-top temperatures on Wednesday with the snow-to-liquid ratio dropping to less than 10 (i.e., more than 10% water content). Snow levels will also rise to close to 8000 feet in the Cottonwoods. Provided we only get a brief visit by the AR, as presently forecast, water totals in the Cottonwoods will be much lower than we saw during the last event, although snow and snow water equivalent rates could be strong at times late Wednesday and Thursday.
If you don't like these Cascadian conditions, wait a couple of days and head to Zion on Friday to enjoy some 70 degree sun.
