Ag Weather Impacts

As we head into the latter half of May, we're seeing growing degrees really begin to accumulate rapidly. Look for temperatures today and Wednesday to average 8 to 10 degrees above normal. Now we're watching two low pressure areas over Nevada and northern California. A southerly flow ahead of these systems will push moisture into the Columbia Basin and produce showers Wednesday through Friday. There is even a chance for embedded thunderstorms Wednesday and Thursday. Most rainfall amounts should be only a tenth to third of an inch, but a few farms may get a half to one inch with thunderstorms. Where the significant rain occurs and followed by slightly cooler temperatures this should help dryland crops, especially those that missed earlier rain west of Prosser, Boardman and Heppner. If you have not gathered hay by Wednesday afternoon it could be subject to moisture damage. Look for lower rain chances this weekend into the middle of next week. These upcoming three days of warm temperatures, clouds, higher humidity and leaf wetness may increase disease potential on susceptible vegetation. Light winds will aid spraying. Crop water use over the next 7 days will range between an inch and a quarter and an inch and a half for wheat and alfalfa and around 1 inch for lawns. It looks like above normal temperatures will dominate until the end of the month.
