Synopsis...strong high pressure will prevail across the region
through the first part of next week. Moisture will slowly increase
across the south into the upcoming weekend...then spread across
the remainder of the region by early next week.
Discussion...an expansive middle level ridge remains centered across
the Southern Plains this evening...with the associated elongated
axis extending westward through The Four Corners region and into
the southern Great Basin. To the south of this axis moisture has
become well established across the Desert Southwest...while north
of the axis the airmass remains quite dry across much of the Great
Basin including the forecast area.
This ridge axis is forecast to amplify over the next couple of
days while pivoting across the Great Basin. This will allow deeper
moisture to slowly encroach on southern Utah...while middle level
moisture seeps northward across the southern half of the state. As
a result would expect to see a gradual uptick in convection across
the south through the remainder of the week and into the upcoming
weekend...while the north remains generally dry.
With the amplifying ridge axis anticipate a continued warming
trend across the north with temperatures returning to normal or
slightly above normal values by Friday...while the increase in
moisture across the south will allow for a bit of a cooling trend.
Going overnight forecast looks in good shape and no updates are
Aviation...VFR conditions will prevail at kslc through the taf
period...with northerly winds switching back to the south between
03 and 04z.
