AgWeatherNet Weekly Weather Outlook for October 15 to October 21, 2016

Stormy This Weekend; From Unsettled to Drier and Warmer Next Week

Nic Loyd, Meteorologist, 509-786-9357

A second, powerful storm will be barreling toward Washington on Saturday, even as the state is still reeling from the Thursday/Friday storm number one. The result should be additional heavy rainfall and strong winds. In fact, winds on Saturday evening could gust to over 70 mph in parts of western Washington. Following a stormy night, Sunday is likely to be less wet in western areas, and drier in central areas, even as gusty winds continue east of the Cascades. Overall, numerous impacts are anticipated this weekend, including urban and river flooding, high waves at the coast, and potential downed trees and power outages. Another low pressure system is possible for early next week, although it would likely be more garden variety in nature and strength. Still, after a period where some western locations may have seen five (or more) inches of rain in as many days, any additional unsettled weather early next week could be more impactful than normal. Although clouds are expected to keep high temperatures in check, lows may be fairly mild given the active conditions. A dirty ridge of high pressure should build into Washington later next week, bringing warmer days and somewhat calmer conditions to the region. However, the ridge may not be strong enough to prevent some periodic rainfall in northwestern parts of the state.
