This forecast is coming out too late to factor into our standings or anything like that, but it will serve as a send off to the newly retiring Forecast.io. Starting on January 1st, we will be using Clime. I would love to use Fox Weather, but they still haven’t managed to produce a website with local forecasting.
At 956PM, MT, Lewiston was reporting cloudy skies with a temperature of 42 degrees. While the west didn’t experiences the frigid temperatures seen in the eastern 2/3 of the country over Christmas, a deep trough has set up over the Rockies, with a strong jet, a so called atmospheric river, pumping moisture into the Pacific Northwest. Winter Weather advisories have been issued just to the north of Lewiston, with more to the south. It remains quite likely that snow is on it’s way in Lewiston as well.
The next round of wet weather is already Pressing ashore in western Washington and Oregon, bringing steady precipitation to the Cascades. Lewiston’s presence between the Cascades and the Rockies of western Montana will spare some of the more significant snows, as will temperatures that will flirt with freezing. Additionally, a prominent surface feature is forecast to organize in the Great Basin, south of Idaho through the next two days, sapping Lewiston’s moisture and ultimately bringing colder temperatures as the snow ends. Nevertheless, snow with a bit of light rain mixed in are possible from mid morning tomorrow and onward for about 24 hours before clearing arrives.

Clouds and the amount of precipitation in Lewiston will all play a factor. I think there is a huge bust potential overall with this dynamic system in the mountains. I am banking on it skewing colder. Look at all the rain coming for the Cascades at this hour!
And with that, so long, Forecast.io!
