Area Forecast Discussion
National Weather Service Salt Lake City UT
913 AM MDT Wed Oct 28 2020

.SYNOPSIS...High pressure will remain over the western United
States over the next several days. This will result in continued
dry conditions over Utah and southwest Wyoming, with temperatures
returning to near or above seasonal normals by late in the work


.DISCUSSION...The upper low that has been tracking across the
Desert Southwest is moving into Texas this morning. Behind it,
high pressure centered off the California coast is building into
the Great Basin, keeping Utah and southwest Wyoming under a dry
northerly flow aloft. The orientation of this flow is resulted in
some elevated winds in prone gaps of Washington county, but
otherwise winds are generally light. The warming trend in
temperatures will continue today, with maxes running around 5F
above yesterday`s values over northern Utah, and up to 10F warmer
over southern Utah.

As high pressure continues to build, the warming trend will
continue for the remainder of the work week. By Friday, maxes
across the area should be at least a couple of degrees above
normal for this time of year as conditions remain dry. A Pacific
Northwest storm system moving over the top of the ridge late
Friday into Saturday will flatten it some, bringing a more zonal
flow and curbing the warming trend for the weekend. However, the
ridge should quickly rebuild by early next week.

No updates expected to the forecast this morning.


.AVIATION...The SLC terminal will see VFR conditions throughout
the day with mostly clear skies. Southeast winds are expected to
shift to the northwest between 17Z and 19Z.


.FIRE WEATHER...Behind an exiting low pressure system, high
pressure off the Pacific coast will build over the western United
States through the work week. This will result in a steady warming
trend, with temperatures return to values at or above seasonal
normals across the district by Friday as conditions remain dry and
stable. Temporary weakening of the ridge will curb the warming
trend to start the weekend, but the ridge will then rebuild by
early next week.
