Weather Underground midday recap for Wednesday, November 04, 2009.

Chilly temperatures and pockets of wet weather developed in the northeastern quadrant of the nation of Wednesday as a weakening low pressure system moved through the Ohio Valley. Flow around this system swept across the Great Lakes to produce a few areas of light rainfall in northern Michigan and southwestern New York. Blustery air from the North also streamed into the region and created a chance for light snowfall development through the remainder of the day. Meanwhile, a warm front associated with this system sparked scattered showers in West Virginia as it became curled across Kentucky and the central Appalachians by the afternoon. The system's dry cold front produced no significant weather activity as it swept though the Mid-Mississippi Valley and the Southern Plains.

To the South, dry and fair weather conditions with mostly sunny skies and warm temperatures persisted in the Southeast as high pressure lingered near the Gulf Coast. Prolonged low relative humidity levels and breezy winds across the Florida Panhandle and the Big Bend created a risk of fire danger throughout the latter half of the day.

In the West, high pressure along the West Coast trekked further inland on Wednesday and became ridged over much of the Intermountain West. Ridging over the region translated into warm daytime temperatures and dry weather conditions throughout the afternoon. As the system exited the Coast, low pressure in the eastern Pacific brought increasing clouds and cooler temperatures to the coastal areas of California and the Pacific Northwest.

Temperatures in the Lower 48 states Wednesday have ranged from a morning low of 10 degrees at Mt. Washington, N.H. to a midday high of 96 degrees at Williams Gateway Airport, Ariz.
