Ag Weather Impacts

Rainfall this past week was mainly a tenth to a third of an inch. The Walla Walla area got the most at around a half inch. Look for a blocking ridge of high pressure to keep storms away from the inland northwest this weekend into early next week. The combination of warmer air aloft and very light winds will contribute to strong inversions setting up and increasing areas of fog and low clouds. Yesterday, temperatures were 10 to 15 degrees above normal along the Oregon border and close to normal across the rest of the area. Now, once the fog sets up we'll likely see below normal daytime temperatures area wide. Soil temperatures remain in the mid and upper 30s and will likely show little change into the middle of next week. It does look like the ridge will break down by the middle of next week with the next chance for rain moving in from the southwest on Thursday. There is a good chance for a succession of storms for next weekend into the following week with a mild west to southwest flow aloft. The latest drought monitor continues to shows moderate drought in the Columbia Basin, with the exception of only abnormally dry in the Ellensburg and Yakima areas. This drought designation is likely because for the water year that began on October first, most farms are only at 75 to 90 percent of normal precipitation.
