Area forecast discussion
National Weather Service Salt Lake City Utah
908 PM MST Friday Feb 5 2016
Synopsis...a weak weather disturbance racing east across the
northern rockies Saturday will be followed by strong high pressure
aloft across the western states beginning early next week.
Discussion...a fairly strong upper level trough currently along
the Pacific northwest and britcol coast will continue east across
the northern rockies on Saturday. This feature will lower heights
a bit over Utah and allow for slightly cooler air aloft to slip
into northern Utah during the days. The bulk of any precipitation will
remain well north of the state near the best dynamic lift over the
northern rockies. Over northern Utah the likely outcome will be a
modest increase in clouds with a few light showers possible near
the Idaho border during the day.
Rapidly building heights near the West Coast late in the weekend
will eventually evolve into a strong and quite broad upper ridge
encompassing the western Continental U.S. Through at least the middle of
next week. Increasing areas of valley fog and urban haze the main
weather concern under the ridge...with a substantial warming trend
for the higher elevations and far southern valleys early in the
Aviation...generally light southeasterly winds will prevail at the
kslc terminal through the night. There is a 10 percent chance of
brief ceilings near 4kft through 05z. Otherwise...haze/mist may bring
reduced visibilities tonight...with a 20 percent chance of MVFR
visibilities developing after 10z.
