AgWeatherNet Weekly Weather Outlook for February 6 to February 12, 2016

Unsettled on Saturday; Dry and Mild Next Week

Nic Loyd, Meteorologist, 509-786-9357

After the Friday/Saturday storm departs the state, a strong and summer-like ridge of high pressure will build over the region on Sunday, and may persist through next Friday. The result should be dry, mild, and calm weather for much of next week.

On Saturday, rain chances are expected to decrease in western and eastern areas, while high mountain snow tapers off. Central Washington is likely to be mild, dry, and breezy. Sunday will be a transition day, before a stable, warm dome of air becomes well established over the Northwest by Monday. Given the offshore flow, coastal foothills may become quite warm early next week, as some sites could reach 70 degrees. The high mountains should also be unusually warm and sunny. By contrast, a lack of mixing in the central lowlands means that not all of the potential warmth will be realized at the surface. Still, all areas can expect well above normal temperatures.

One wildcard is the ultimate inversion strength and daytime low cloud or fog potential. It is a tough call given the late stage of the winter, but central areas are most likely to see such development. Any foggy locations should anticipate smaller diurnal temperature cycles, while sunny areas could expect warmer days and cooler nights. As this latest iteration of the monster ridge that plagued Washington for much of the last two years weakens later in the period, a return to onshore flow may bring slight daytime cooling to the coast and mountains, along with warming to central Washington, especially at night. A wetter and more active pattern could resume next weekend or sometime in mid February, but abnormal warmth seems determined to hold firm for the foreseeable future.
