Area forecast discussion
National Weather Service Salt Lake City Utah

Synopsis...high pressure will remain the dominant weather feature
over Utah and southwest Wyoming for much of the week. A weak
disturbance will graze northern portions of the area midweek. A
more active weather pattern is possible for the upcoming weekend.
Discussion...the upper ridge currently positioned near the West
Coast will gradually shift east into the Great Basin by Wednesday.
A series of weak weather disturbances will crest this ridge
during the week. The trajectory of these feature will be into the
northern rockies, then turning southeast along the Continental
Divide during the week.
Periodic mid/high level cloud cover will cut across mainly
northern Utah/southwest Wyoming with these passing dynamic
features. The only feature that will have any notable impact will
be the shortwave that will graze northern Utah/southwest Wyoming
late Tuesday night through Wednesday morning. This disturbance,
much like the one that moved into Utah last night, will see the
mid-level shortwave outrunning the low-level cold advection. This
lack of good baroclinic structure will likely lead to increasing
clouds with little or no chance for precip outside of flurries in
the far northern Wasatch and western Uinta ranges.
Warmer temperatures and dry conditions will settle across the
state during the latter half of the week as the upper ridge
settles across the Great Basin. The first decent chance for some
precipitation could finally arrive with the next upper trough
moving southeast into the northern rockies/northern Great Basin
early in the upcoming weekend.
Aviation...light south-southeast winds this evening will persist
through Tuesday morning, followed by a return to northwest winds
between 19-20z. VFR conditions will exist throughout the current
