Now this is gonna get interesting… who remembers what the meaning of life is – from hitchhikers guide to the galaxy ?  42 and this is also Boise’s Magic temp for snow to be falling at Bogus, for most storms. Let’s Keep It Simple Silly (KISS) so we don’t have to explain the adiabatic temp lapse rate decreasing 3F /1000 ft increase in elevation. 

The NWS forecasts for Boise for Tues shows temps pushing 43 F and Bogus at 34 with rain snow mix and snow line / level around 6,600 ft !!! Elevation matters and makes a difference! Stay tuned and let’s hope the snow on ground and frozen soils can keep the temps cooler than the models are predicting and snow keeps falling above 6,000 ft !!!

In Idaho, rain-on-snow runoff events happen below 5,000 ft from mid-Nov to mid-Feb. We’re step-up nicely for rapid runoff if the rain intensity and duration occurs because of valley snow cover and frozen soils. Soils in my backyard are frozen deeper than my shovel can easily dig. What’s happening in your backyard ?

It’s always interesting to watch these storms set up as they cross the Pacific, the ocean swells they produce and becomes an Atmospheric River when they hit the west coast and move inland.  

Get ready to enjoy the ride from this AR ! Be safe whether you’re deep in snow on a mountain side as avalanche danger will increase from this heavy snowfall on the colder lighter older snow layers OR if you’re watching the creeks and rivers rise in the valley bottoms! How high the rivers rise depends on duration / intensity of rain and temps above 32F.

The good news from OpenSnow mentions the weather door in PNW may remain open in early Jan to start the New Year !!!
