.SHORT TERM...Today through Wednesday night.
It will be another very warm and dry day across southeast Idaho
today with well above normal high temperatures in the 50s to lower
60s valleys and mainly 40s to lower 50s mountains. Rain and snow
will move into the central mountains during the day on Wednesday
and gradually spread east overnight. Snow levels will start out
between 6 and 7 thousand feet on Wednesday ahead of the cold front
and drop to 5 to 6 thousand feet Wednesday. Any snowfall of over 6
inches Wednesday and Wednesday night will be above 7 thousand
feet. Rain and snow will spread over the remainder of southeast
Idaho late Wednesday night. Highs Wednesday will remain warm ahead
of the frontal system with 50s to near 60 again in the valleys and
40s in the mountains. Lows tonight in the 20s mountains and 30s
valleys and again Wednesday night.
GK

.LONG TERM...Thursday through Tuesday. Widespread rain and snow is
expected for most of Thursday, before clearing out a bit from west
east Thursday night. Snow levels will be falling as a cold front
arrives, but do expect them to peak at 6000-7000ft out ahead of it.
It will be breezy but with warmer temperatures, blowing and drifting
snow will be mitigated a bit. Southerly winds will create some
downslope from Burley to Driggs, but will create opposite from the
Wood River Valley through Island Park on that side of the Snake
Plain. Current trends keep most of the accumulating snow above
6500ft, with light accumulations below that. At the moment, the end
of widespread precipitation will occur before snow levels fully
crash later Thursday. The latest forecast has 12" or more likely for
the Lost River Range, as well as portions of the White Knob,
Boulder, Pioneer and Sawtooth Mountains. Same can be said from
Monida Pass to Sawtell Peak. The chance of more than 16" is between
20-40% depending on location. Across the Bear River Range, there is
only a 10-20% chance of more than a foot. Showers will linger Friday
as the actual splitting storm crosses the state. Another round of
moisture is poised to hit eastern Idaho over the weekend, especially
Sunday and into Monday. This round looks to hit the
Sawtooths/surrounding ranges, eastern highlands, and Bear River
Range hardest. There is a 40-50% chance of more than 1" of moisture
(rain/melted snow) for the Big Holes/Tetons and the Bear River
Range. There is a 25-45% chance of exceeding 1.5" for the Sawtooths.
More precipitation is expected Monday and Tuesday. It definitely
looks like a wetter and cooler pattern heading our way. Keyes
