Area forecast discussion 
National Weather Service Salt Lake City Utah
1018 am MST sun Jan 25 2015

Synopsis...strong high pressure will build into the western
states through tomorrow. The next storm system approaching from
the southwest will impact the area Monday night through Wednesday.


Discussion...a high amplitude ridge over the West Coast will
shift over the Great Basin through today...leading to drier and
warmer conditions across Utah and southwest Wyoming. Some low
stratus is still lingering across portions of northern Utah and
Uinta County Wyoming...but should generally decrease through the day
due to dry air moving in from the west...with sunny skies
developing across most of the area.

This ridge will remain in place through Monday...with very warm
temperatures for this time of year expected...especially across
the higher terrain. The storm coming up from the south Monday
night through Wednesday still looks fine...though will have to
watch model trends to see exactly how far west the low
tracks...with some concern that the best forcing mostly hugs the
Utah/Nevada border.

Updated the forecast earlier to tweak sky cover for this
afternoon. Maximum temperature forecast could be too low in some
locations...but current guidance is only a couple degrees warmer
than ongoing forecast. May update if quick warming trends continue
through noontime.


Aviation...the stratus layer from earlier has largely dissipated
over the slc terminal...though a brief return to a ceiling around
5000 feet above ground level will be possible through 20z. Otherwise...light
southerly winds will shift to the north to northwest between
