Area Forecast Discussion
National Weather Service Pocatello ID
210 PM MST Fri Feb 24 2017

.SHORT TERM...Tonight through Saturday night. Per the most recent
radar imagery, light snowfall continued to fall from Pocatello north
through Idaho Falls and points eastward to the Wyoming border. The
threat of moderate snowfall has mostly ended however and thus all
the winter warnings and advisories have been cancelled for the
remainder of this evening. Cooler temperatures have significantly
slowed snow melt across the region and many of the hydrologic
warnings and advisories have been eased (see discussion below). A
trough digging SE through Montana Saturday will support ongoing
light snow along the Montana/Wyoming divide region through Saturday
evening. Temps remain cool through the period. Huston

Sunday morning through Monday afternoon. Next weak winter storm
enters during the day Sun and spreads moisture threat from north to
south with its approach from the north. The storm peaks Mon morning,
with Winter Weather Advisory criteria only being reached at extreme
elevations. Expecting only 1 to 2 inches in the Snake River plain
and eastern Magic Valley. Wind starts to increase to at least brisk
conditions on Mon afternoon after the cold front pushes through.
This slows but does not stop the expected warming trend. Messick

.LONG TERM...Monday night through Friday. A weak boundary is
forecast to pass through Central Idaho early Tuesday morning, which
will enhance precipitation potentials along the Continental  Divide
and Upper Snake Highlands Monday evening/Tuesday morning. This will
also aid in keeping winds elevated across the Snake River Plain
through Tuesday. High pressure will begin to build in late Tuesday
and continue through Friday, allowing for clearing conditions.
Eastern Highland locations are expected to continue with light snow
showers through Wednesday, however. Temperatures will build some
Thursday and Friday into the upper 30s and possibly into the 40s for
the lower Snake River Plain/Eastern Magic Valley areas. The rest of
Idaho will continue to struggle to reach much higher temperatures
beyond freezing. NP/MH

.AVIATION...Slow clearing from west to east during the evening, with
most of the IFR conditions ending during the late afternoon. Wind
will also subside by 25/00 UTC. May see some problems with morning
stratus at KIDA and KDIJ. Messick

.HYDROLOGY...After coord with county EM`s, have trimmed back all
hydro warnings and advisories for the Upper Snake River Plain and
Southern Highlands due to cooler temperatures now and expected to
continue through early next week. Eastern Magic Valley is still have
issues with water ponding and we have continued all the Areal Flood
Warnings in that area. Next warm up comes late next week. Huston
