Weather Underground Forecast for Thursday, November 05, 2009.

Wintry weather will persist in the Northeastern US on Thursday as a weak low pressure system continues tracking through eastern Canada. Flow around this system will pick up cool and moist air from the Great Lakes and create a cold front that will extend from Main into New England. The southern end of the front will push well off shore early in the morning. This system will allow for light and scattered snow showers in the early morning hours of Thursday over the Northeast as highs will remain in the 30s and 40s. Little snow fall accumulation is anticipated as this system has used up most of its moisture. However, the higher elevations may see up to 2-3 inches.

Behind this system in the Plains and Mississippi River Valley, high pressure will continue building in from the west. This will bring another day of sunny skies and mild weather. Expect highs in the Upper Midwest to approach the 50s, while the Central and Southern Plains will reach into the 60s and 70s. Another chilly night is in store for the Central and Southern Plains as high pressure will bring drastic overnight cooling. Frost advisories have been issues for the region as lows will dip into the 30s and 40s.

In the West, a trough of low pressure will finally move into the Pacific Northwest. The system will push a cold front over the region that will bring near an inch of rain to Washington and Oregon. The system will push cooler conditions with partly cloudy skies over California.

Temperatures in the Lower 48 states Wednesday ranged from a low of 9 degrees at Daniel, Wyo. to a high of 97 degrees at Mesa, Ariz.
