Weather Underground Forecast for Wednesday, November 02, 2011.
The cold front that brought a snow storm event to the Rockies Tuesday will continue to surge southeast and merge with another front over the Central U.S. Wednesday morning. As this occurs, expect an expansive area of rain with isolated thunderstorms from the Upper Midwest and Great Lakes southwestward through the Mississippi Valley and Central Plains. In addition, moderate to heavy snow will continue over the Central and Southern Rockies, moving onto the High Plains Wednesday morning. Snow accumulations will range from 1 to 3 inches with locally higher amounts. Winds are expected 25 to 40 mph range, with gusts to 50 mph, which are likely to cause areas of blowing snow, reduce visibility and create hazardous driving conditions. Temperatures will be turning much colder with windchill readings possible dropping to 20s and teens. This snow storm should end by mid-afternoon as the front pushes into the Southern Plains.
In the East, a strong ridge of high pressure will hold in place, providing fair weather conditions.
Out West, a cold front will approach the coast Wednesday evening, bringing coastal rain and high elevation snow across the Pacific Northwest Wednesday night. This system is expected to push into Northern California and northern Intermountain West by Thursday morning. Apart from the precipitation, this front will bring the first cold surge of the season across the West Coast from Thursday to Saturday. Temperatures are expected to run 10 to 15 degrees below normal. Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 15 degrees at Rome, Ore. to a high of 89 degrees at Fort Stockton, Texas
