A ridge of high pressure is now with us, until Friday's storm.
This ridge is bringing back a southerly flow of air and boosting our temperatures back up into the 20's and 30's for highs, which is right on average for this time of year.
An inversion will set up, keeping a valley haze over the Plain. Also, some mountain communities will be WARMER than the Plain, with colder air being held low in elevation with the inversion.
A chance of patchy freezing fog in the valleys for Thursday morning. With cold temps and a few snow/forst flakes out of the low clouds.
A weak storm system will sweep through the state of Montana, tapping in some light snow showers into eastern Idaho and western Wyoming. No more than an inch is expected in the Snake River Plain, and one to three inches in the High Country.
Weekend temperatures will max out into the upper 20's and lower 30's for the Plain.
