Autumn Washington Weather Summary Reports Bitter Cold Events

AgWeatherNet shows impact on vineyards, other crops.

In stark contrast to the ferocity of last year, this November went out like a lamb, report Washington State University weather watchers.

Thanksgiving's blast of bitter, arctic air however raked across the eastern state landscape, with effects still being felt in decreased vineyard production. November ended with fairly benign weather conditions, however, as temperatures across the state were nearer to slightly below normal during the month, with several very warm days late in November in southeastern Washington.

Overall, autumn temperatures were above normal in eastern Washington and near normal in the west near Mt. Vernon.

There were no unprecedented weather events this November.

The month exhibited a normal degree of weather variability, featuring stormy weather interspersed with dry and calmer periods.  Walla Walla experienced three days with temperatures in the 60s during the last 10 days of the month. There were also blustery days in November, with winds in certain locations gusting to around 60 mph on Nov. 13.  Some areas in southwestern Washington, like WSU's AgWeatherNet station at Long Beach, recorded nearly 10 inches of rain during the month.

A web-based publically available system, AgWeatherNet provides access to real-time weather data and value added products from Washington State University's statewide weather network, along with decision aids for agricultural producers and other users seeking information on how to manage during certain adverse weather conditions.

The network is 134 stations strong, with sites located mostly in irrigated regions of Washington, particularly in the agricultural rich eastern part of the state. The network recently has undergone significant expansions in western Washington, however, and in dry land regions of the state.

The system includes stations with multiple weather information gathering devices that report their findings directly into network computers, which farmers can access without cost to determine how climate may be changing in their local regions. The system has grown substantially during the last five years, and is managed by Washington State University.
