The upper level high pressure ridge that has given areas of fog, but otherwise fairly tranquil weather this week across the Columbia Basin is moving east. It’s being pushed east by a low pressure trof that brought locally heavy rain to California much of this week. The trof will weaken a little as it moves into the Columbia Basin, so precipitation amounts of only a quarter inch or less are expected from tonight into Saturday night. The mountains should get 5 to 8 inches of snow which will help the snowpack that has been lagging so far this water year. Newborn or weak livestock will be need be sheltered or given extra care since the precipitation combined with temperatures in the 30s will likely cause severe cold stress, especially tonight and Saturday morning. If your farm to market transport involves mountain travel above 3500 feet, the snow may cause some issues. After Sunday, the ridge rebuilds for dry weather for Monday and Tuesday. Temperatures should average close to normal and there does not appear to be any extreme cold on the horizon. That ridge will break down paving the way for a few more rounds of rain and mountain snow for Wednesday night into next weekend. And it’s quite possible, the active weather could continue into the third week of December as it looks like the jet stream continues to meander between a ridge and a trof every 3 to 4 days.
