.DISCUSSION...As a stout high pressure ridge lingers across the
western US, extremely anomalous temperatures are expected to
continue through Wednesday. Highs once again soar around 25
degrees above average in most locations across Utah and southwest
Wyoming, which will challenge daily temperature records. The
temperature in Salt Lake City will even rival the previous all-
time high March temperature of 84 degrees... set only three days
ago on March 21st. Current guidance suggests a 35% chance to meet
or exceed 84 degrees at KSLC on Wednesday. This anomalous heat
will be aided by increased warm, southwesterly flow across the
area ahead of an approaching upper-level low. Gusty southwest
winds are expected to develop areawide Wednesday afternoon, with
strongest gusts of 25-30 mph expected across southwest Utah and
portions of the West Desert.

A cold front associated with the aforementioned low is expected
to pass through the region late Wednesday into Thursday morning.
While this front will be mainly dry, some virga showers are
expected across northern Utah along the frontal boundary. Light
rain may be observed in isolated stronger cells that develop
through the evening. Any shower activity is expected to taper
early Thursday morning. A slight cooldown mainly across northern
Utah is expected through Friday as post- frontal northwesterly
winds prevail across the area, though temperatures will still run
around 10 degrees above average.

A shift in the pattern may arrive as early as Sunday, with 75% of
ensemble members on board for the development of a trough across
the northern Pacific to finally break down the persistent ridge.
There is still considerable uncertainty early next week on when or
if this trough will move inland. Regardless, some flavor of
cooling is expected next week, with better potential for
accumulating precipitation.

.AVIATION...KSLC...High pressure remains the dominating influence,
bringing VFR conditions. Southeasterly winds will prevail through
the rest of the night into Wednesday morning. A shift to
northwesterly is expected around 18-19z Wednesday. There is a 20%
chance of occasional light rain showers or virga Wednesday evening
between 00-07z, although associated CIGS should largely remain above
6kft. The diurnal wind shift to southerly Wednesday night will
likely either be delayed or not occur at all.

.REST OF UTAH AND SOUTHWEST WYOMING...Little change to the ongoing
pattern as high pressure remains in control. Some high clouds will
filter in overhead at northern terminals tonight, but VFR conditions
prevail areawide. Winds will tend to follow a diurnally normal
pattern, with some modest gusts mixing in at higher elevations and
exposed terminals (e.g. EVW/CDC) Wednesday afternoon.
