Area forecast discussion 
National Weather Service Pocatello Idaho
335 am MST Friday Jan 30 2015

Short through Sunday. A system to our south centered
over Southern California is bringing middle level clouds across the
area this morning. These clouds are limiting the amount of fog we
are seeing across the area this morning. However...patchy fog is
still possible this morning. Though any fog we will see will not
be very dense. Clouds will clear up Friday night into Saturday.
Expect patchy fog across lower areas Saturday morning. A weak wave
passes over Montana and clips our upper snake Highlands Saturday
afternoon into Sunday. Expect little to no precipitation and
slightly breezy winds. High pressure ridging builds back into the
area Sunday. Look for moisture to move into our area in northwest
flow bringing precipitation mainly Sunday night across the upper
central mountains...upper snake Highlands and eastern Highlands.

Long term...Monday through Friday.
Both European and GFS models continue trend of break down of upper
level ridge Monday into Wednesday with some precipitation mainly in
mountains expected Monday and Tuesday which should be the wettest
days in the long term. Some disagreement beyond Tuesday as upper
ridge rebuilds but both filter through some moisture and light
precipitation. Through Friday but the trends are for a drying out
late next week. Temperatures should remain above normal through
the entire long term period.


Aviation...large swath of middle clouds over southeast Idaho has kept
fog and stratus from becoming too widespread at taf sites this
morning. All sites VFR and expect trend to continue throughout
today. Light winds expected today as well.
