AVIATION...18z TAFs

Expecting mostly VFR conditions during the period, however shower activity may make for periodic MVFR conditions at times later this afternoon into the early evening. Rain showers are expected to be light at most sites, however BDN and especially RDM could see light snowfall this afternoon. Accumulations are expected to be minimal, however vsbys and cigs could drop to IFR at times (30-40% confidence). Winds will start to pick up out of the SW and W across most sites as well, starting in the late morning for BDN/RDM, and spreading to most other sites by the late evening and overnight hours heading into Thursday. Otherwise expect mostly bkn mid-level cigs outside of precipitation. 74

PREV DISCUSSION

/issued 356 AM PST Wed Jan 7 2026/

DISCUSSION...Radar shows valley rain and mountain snow impacting the region, with most of the current heavier precip located over the Blue Mountains and the Foothills of the Blues. That area of precipitation is expected to move out into the Idaho region as we head into the later morning hours. On the other hand, parts of the Cascades will continue to see periods of light to moderate snow going into Wednesday morning. Snow rates in the Cascades at the time of writing this discussion have temporary lessen, but will increase by the early afternoon. Parts of the Northern Blue Mountains will see another increase of snow rates heading into the late afternoon and will stay more or less consistent across the mountains until Thursday afternoon. We've seen a slight tick up in forecasted snow amounts via the NBM in the latest run tonight but the message still remains fairly the same with several feet still expected in many parts of the Cascades and Northern Blue Mountains.

Conditions will greatly improve going into Friday as a ridge pushes ashore and brings mostly dry conditions with some temporary warmer highs in the low 50s across the Columbia Basin. Despite that, low temperatures across the region will remain below freezing for the most part. This pattern will dominate through early next week, bringing some relief from the unsettled weather in the short term. Winds tonight remain breezy with some locally windy spots reporting 40 plus mph gusts. Not seeing criteria widespread enough to warrant a Wind Advisory, but some populated areas (such as Pasco) recorded 38 mph earlier tonight. Not expecting conditions to get to Wind Advisory level despite the upcoming cold frontal passage today increasing pressure gradient to some degree. Chances are moderate (50 to 70 percent) we'll continue to see breezy to locally windy conditions through today with gusts up to 35-40 mph.
