Synopsis...high pressure will build across the region through
Friday maintaining warmer than normal temperatures. A cold front
will push through the region Saturday bringing a cooling trend,
along with a few snow showers possible over northeast Utah and
Discussion...a weakening shortwave trough moving into the western
Great Basin this evening will continue to work on weakening the
ridge in place over Utah. Mid and high clouds associated with this
system will continue to stream across Utah overnight, which should
allow for warmer overnight temperatures compared to last night.
Behind said trough, a second but splitting trough will make its way
inland. The northern and southern branches will split around Utah,
although the northern branch may maintain enough jet energy and
brief cold advection to produce a few weak showers over northeast
Utah and southwest Wyoming on Saturday. Latest models are not all
that promising, however. Still, expect a cold front to bring
temperatures down to closer to 5-10 degrees above climatological
normals for the weekend (compared to the 15-20 degrees above climo
expected for tomorrow).
Behind this trough, high pressure will quickly build back into the
area. Looking for more of a change beginning around midweek next
week, with latest models settling for now on a solution indicating a
a closed low over the Desert Southwest which would draw moisture
with high snow levels into southern Utah. However, models are still
in a state of flux, so stay tuned.
Aviation... VFR conditions will be maintained at the slc terminal
through the taf period under mid and high clouds. Southeasterly
drainage winds are expected through the night. Winds will become
northwest again Friday between 19-20z. Speeds are expected to remain
7 knots or less.
