You can plan on much cooler air and a few showers to move into the Columbia Basin today on the heels of a vigorous cold front. Temperatures today will be 10 to 15 degrees colder than Monday and then on Wednesday it will likely be another 5 to 10 degrees colder than today. Showers will be spotty yielding under a tenth of an inch, except more numerous showers with amounts a tenth to a quarter inch near the Blue Mounains. The heavier rain amounts near the Blue Mountains may cause moderate to severe cold stress for exposed newborn or weak livestock. If you did not get a freeze last week, it looks like your growing season will likely come to an end Wednesday night with a hard freeze when the skies clear and the wind decreases. Most farms will have temperatures in the lower to mid 20s Thursday morning with subfreezing conditions for 6 to 9 hours. Exposed water pipes may freeze unless protective measures are taken. This cold will bring a slight setback on germination and development of winter wheat and pastures, but should also setback the bug population. Soil temperatures at the 2 inch depth are currently averaging in the mid 50s to lower 60s into the lower to mid 40s on Thursday. Daytime temperatures should recover to slightly below normal this weekend, which should allow soils to warm into the upper 40s to lower 50s. Once the precipitation ends on Wednesday, generally dry conditions should prevail until at least the middle of next week.
