Northwest

Weather Underground midday recap for Wednesday, November 11, 2009.

Wet and stormy weather persisted in the Mid-Atlantic states as the remnant low pressure system of Ida became positioned along the Carolina Coast on Wednesday.

The system continued to pulled moisture from the Atlantic Ocean into the Mid-Atlantic states, producing persistent showers, areas of heavy rainfall, and thunderstorms through the afternoon. Prolonged and heavy rainfall caused areas of excessive runoff and flooding near small streams and creeks, as well as ponding in urban areas. Damaging onshore winds of 15 to 25 mph with gusts near 35 mph accompanied unsettled weather activity and ushered cooler conditions into the Mid-Atlantic. Meanwhile, the Southeast states began to see drier weather conditions as the system exited to the coast.

To the north, the Great Lakes and Northeast saw fairly tranquil and warm weather conditions as high pressure remained poised over the Great Lakes.

In the West, cool temperatures and gloomy skies developed throughout the Pacific Northwest on Wednesday as low pressure pushed inland. Moist, onshore flow streamed into the region and sparked areas of light, scattered rainfall near the Pacific Northwest coast and northern California, as well as snow showers in the Cascades and the Northern Rockies. Cooler daytime temperatures also developed across much of California and the Central Great Basin, while low-level clouds remained along the remainder of the West Coast.

Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 15 degrees at Kremmling, Colo. to a midday high of 89 degrees at Williams Gateway Airport, Ariz.
