AgWeatherNet Weekly Weather Outlook for April 28 to May 4, 2018

Cooler and Unsettled Into Early Next Week; Warmer and Drier Thereafter

Nic Loyd, Meteorologist, 509-786-9357

A notable weather pattern shift is imminent, as an upper level area of low pressure begins to move inland over Oregon tonight. The very warm and summer-like conditions of late will be replaced with cooler and unsettled weather for this weekend and early next week. Although the upcoming regime is not abnormal for this time of the year, the change may seem abrupt after the recent warm spell. The drop in high temperatures in eastern Washington from Friday to Saturday should be on the order of 25 degrees.

Along with much cooler days in the east, periodic winds and increased shower chances are likely, as the low meanders across the Northwest this weekend. It appears that some locations could experience a rather wet couple of days, although much of south central Washington looks to be spared from appreciable rainfall. Somewhat drier and calmer conditions are expected to develop early next week, although very isolated frost is possible during the transition. However, another warm and benign interval is anticipated for later in the period, as daytime temperatures climb back into the 70s and 80s. As you can see, changeable mid to late spring conditions are predicted to persist in the coming days and weeks.
