Rainfall this past weekend was mainly a quarter inch or less but a few spots between Yakima and Sunnyside and over by Dayton got up to ½ inch. Look for a couple minor weather systems to affect the Columbia Basin this week. First of all, plan on a dry cold front on Wednesday to kick up winds a notch and hamper spraying. Than an upper level low pressure area will produce isolated showers and thunderstorms mainly Friday night into Sunday. It looks like the higher rain chances will be near the Cascades and southeast of a line from Dayton to Hermiston to Heppner, but again amounts will be mainly under a quarter inch. So the effect on curing hay and ripening cherries and winter wheat should be minimal. A ridge of high pressure building over the area early next week will produce more dry weather and a return to above normal temperatures. These warm temperatures next week may be of concern for apple sunburn on susceptible varieties and also for spring canola in the bloom stage. Hay balers can expect humidity to be in the 65 to 80 percent range from about midnight to 8 am on most days. Crop water use for the next 7 days will range between and inch and a half and ¾ for tall alfalfa and spring grains. Lawns will use about an inch and a quarter.
