.SHORT TERM...Today through Wednesday night. More light snow is
forecast today as the next "wave" moves across the state. The
target areas will be the Sawtooths and eastern highlands with 2-4"
possible. Other areas will see anywhere from a dusting to a
couple of inches tops. The bigger story today will be the return
of strong winds this afternoon. We are still looking at higher
speeds than yesterday, 20-30mph with higher gusts in most areas.
Sustained to 35mph with gusts of 40-50mph are expected for the
higher peaks of the central mountains and south central highlands.
The WIND ADVISORY for the Snake Plain is still a go with similar
speeds anticipated. Large vehicles will have a rough go of it
especially in crosswind situations. There will be some pockets of
blowing and drifting snow, creating low visibility and slick
spots. Winds should die down overnight, but stay on the breezy
side on Wednesday as well. Behind today`s storm, we will switch to
northwest flow and a ridge building to our south. This will keep
some light snow showers going in the central mountains and eastern
highlands, but coverage will be on the decrease. A few showers are
also possible along/east of I-15 due to upslope conditions.
Temperatures will begin rising tomorrow afternoon, with several
areas pushing to the mid/upper 30s and likely kickstarting
snowmelt and the next round of lowland flooding. Keyes
.LONG TERM...Thursday through Tuesday.
Weak northwest flow will keep low chances for snow showers across
portions of the central Idaho mountains and upper Snake highlands.
Temperatures will warm considerably Friday into Saturday with the
threat of lowland flooding returning. Next system arrives over the
weekend with an initial round of precipitation moving through Friday
night or Saturday with a larger batch of precipitation arriving
Sunday with the cold front. Monday continues to look mainly dry.
Models having difficulty determining how long and strong high
pressure system is for early next week. Potentially could have
another wet system arriving as early as Tuesday or could stay dry
.AVIATION...Another storm system will bring windy conditions along
with snow showers to the region today. Expect reduced ceilings and
visibilities around snow showers.
.HYDROLOGY...Cooler temperatures have helped to mitigate snow melt
issues. The next warm up comes late this week peaking on Saturday
with snow melt follow-through expected into Sunday. Huston
Wind Advisory from noon today to 6 PM MST this evening for
