Rainfall late Sunday and Monday across the Columbia Basin was mainly two tenths of an inch or less. Heavier amounts up to a third of an inch were reported from Walla Walla southwest to Pendleton and Heppner areas. The upper level low pressure area that brought Monday's rain has moved into Montana, but another Pacific system is sliding into about the same position and this one appears a little stronger, so additional rainfall appears likely beginning this afternoon and overnight into Wednesday and ending on Thursday. Thunder is also a definite possibility on Wednesday. Most farms should get a tenth to quarter inch, but those areas near the Cascades and Blue Mountains can expect a quarter to half inch. Although this will cause significant delays for haying, field work, and fall planting, it will add some moisture for dry land pastures and get them started growing out of the dry seasonal dormancy. This upper level low pressure area and clouds will keep daytime temperatures 5 to 10 degrees below normal until this weekend. For chemical applications, washoff risk should be low beginning Friday and winds will be lighter. Crop water use the next few days will drop off to between .05 and .1 inch per day and then increase to around .15 inch per day this weekend. A fast moving system on Sunday may bring a few light showers, but other than that it appears mostly dry conditions are likely from Friday into the middle of next week.
