SHORT TERM /Through Thursday Night/
Issued 232 PM MDT TUE APR 14 2026 An upper trough dropping south along the BC coast will push into the region later tonight bringing valley rain and mountain snow. Precipitation will develop across SE Oregon by late this evening, spreading into SW Idaho overnight. Snow levels of 5000-6500 feet will support snow or a rain/snow mix across mountain valley floors with any minor accumulation melting off by late morning. Precipitation mixes with or changes to rain below 6000 feet with a heavy, wet snow continuing in the higher mountains through Wednesday evening. Liquid equivalent totals over the mountains is 0.75-1.5" over the 24h period from late this evening through Wednesday evening. Above 6500 feet this will translate to 10-20" of snow, with high end amounts of up to 2 feet.

Lower elevations will see periods of rain on Wednesday. By late morning strong southwest flow aloft (30-50 mph at ~10kft) will mix to the surface bringing gusty winds to higher terrain outside of the Snake Plain. The windiest locations will be southern Harney, Malhuer, and Owyhee counties where gusts of 40-45 mph are expected. A cold front will push into the region Wednesday evening bringing a chance of thunderstorms, more gusty winds and lower snow levels. Areas that don't tap into the stronger winds during the day, will see a period of stronger gusts with the frontal passage. This is mostly in the Snake Plain and Weiser Basin. Snow levels will drop to valley floors behind the front as precipitation scatters out. Though it will remain breezy, lower elevations will briefly flirt with freezing temperatures Thursday morning.

The upper low passes overhead on Thursday, keeping a chance of rain/snow/graupel showers at lower elevations with snow showers in the mountains. Daytime instability will support heavier showers and possible thunderstorms in the mountains which could drop brief heavy snow.

Thursday night will see drying conditions and clearing skies as the low exits eastward. This will allow for a widespread freeze, and for many locations a hard freeze (28 degrees or less).

LONG TERM /Friday through Tuesday/
Issued 232 PM MDT TUE APR 14 2026 Strong northwest flow from the back end of the eastward moving trough will continue breezy conditions Friday, with elevated gusts up to 30 mph mainly over Magic Valley and Camas Prairie.
The west-central ID mountains will see a 20-30% chance of snow showers from remnant upper moisture on Friday. Nighttime temperatures will be expected to stay on the colder end, below freezing through Saturday morning. Otherwise, a warming and drying trend will settle in for the weekend as a ridge builds in from the northwest coast. Peak temperatures will hover slightly above normal on Saturday and 5-10 degrees above normal on Sunday.

Long-range guidance continues to favor another low digging down from the Gulf of Alaska early next week, although considerable uncertainty remains over its arrival timing for our area. However, ensembles still favor the late Sunday/Monday time frame. With that, precipitation chances will increase from west to east early Sunday into Monday, reaching 30-60% area-wide by Monday afternoon. Precipitation chances will remain elevated through midweek. The south-southwest flow from this system will keep temperatures near normal when it impacts our area. Gusty winds can be expected ahead of and behind the system passage.
