AgWeatherNet Weekly Weather Outlook for January 23 to January 29, 2016

Typical El Niño Weather Pattern Continues

Nic Loyd, Meteorologist, 509-786-9357

The presently well-established, El Niño-induced circulation pattern featuring a deep trough in the Pacific Ocean and a weak high pressure ridge near the Pacific Northwest is expected to linger for the coming seven days. The resulting southwesterly air flow will periodically direct mild storms toward western Washington. Relatively warm temperatures and somewhat variable weather conditions are forecast to persist through the period.

On Saturday, a slightly cooler disturbance should bring some rainfall as it moves across the southern part of the state. There is likely to be a drier period around Sunday and Monday, before more active conditions return next week. Still, areas east of the Cascades should be notably less wet compared to this past week. As rain returns to northwestern Washington by Tuesday, eastern areas could potentially see much warmer weather later in the period. Looking ahead to next weekend, a temporary pattern change toward cooler and more normal conditions may occur, but it is not certain at this point.
