Area Forecast Discussion

440 AM MST Fri Feb 28 2025

.SHORT TERM (Through 12Z/5AM Sunday)...Ridging will remain the
dominant forecast influence across the forecast region through the
short term. Subsidence associated with the ridge and corresponding
surface high will yield dry conditions, with no precipitation
anticipated. Temperatures will show minimal trends overall, with
seasonably mild afternoon high temperatures, and cool overnights
given effective radiational cooling in the face of calm conditions
and mostly clear skies.

.LONG TERM (After 12Z/5AM Sunday)...On Sunday the mid and upper
level ridge will begin to shift eastward, allowing southerly flow
to impart a gradual increase in moisture. By late Sunday evening,
overnight into Monday, a mid to upper level low will begin
shifting through the Great basin region, and while synoptic
forcing will remain fairly meager, will see precipitation chances
across the local forecast region begin to increase.

Monday on into midweek, the aforementioned low will shift through
Utah, more or less keeping the forecast region under its
influence. Given lingering moisture, will see periods of
precipitation also maintained, with some slight upticks possible
therein depending on the timing of more subtle vort lobes rotating
through the larger scale low/trough pattern. H7 temperatures will
also begin cooling as the low shifts in, with further decreases by
midweek as deeper northwesterly flow starts to become realized.
The result will be cooler temperatures than that of the weekend,
and decreasing snow levels as the event progresses. Uncertainty
is still noted, but generally anticipate some fairly light terrain
snow accumulations throughout the course of the event, with at
least some low end potential for light low elevation accumulations
as well, especially if the forecast trends cooler/wetter.

.AVIATION...Weather expected to remain fairly quiet through the
TAF period with high pressure likely to yield continued VFR
conditions. If not light and fairly variable, winds anticipated to
largely follow typical diurnal pattern with some periods of
variability near typical time of directional shift.
