AgWeatherNet Weekly Weather Outlook for January 13 to January 19, 2018

Drier and Calmer This Weekend; Active Weather Returns Next Week

Nic Loyd, Meteorologist, 509-786-9357

This outlook period will be characterized by two main weather intervals. The first is set to occur this weekend, as a building ridge of high pressure ushers in a more benign pattern. Although light rain should brush especially northwestern Washington on Saturday morning, the general trend looks to be toward drier and calmer conditions. As warm air infiltrates the region from the south, the mountains and the coast are particularly likely to experience rather mild temperatures. Inversions may attempt to become established, which will increase the odds of low clouds and/or fog in the Basin, and perhaps in parts of interior western Washington.

The second interval begins early next week, as dry weather early on Monday gives way to increasing rain chances and breezes by Tuesday. This pattern shift toward active conditions is expected to cause a parade of storms to bring periodic rain and wind to the region. Overall, even as the Northwest transitions from a stable regime to a more unsettled regime, the common theme in the coming days is anticipated to be the persistence of unseasonably mild temperatures.
