West:
A fast moving low ("Alberta Clipper") moving out of western Canada will produce precipitation in Montana, Idaho and Wyoming and south to the Four Corners area. The mountains of central Idaho, Bitterroots, Glacier peaks and Tetons may see 6 to 10 inches of new snow by tonight. Cold air moving in with the system will result in temperatures dropping as much as 30 degrees from yesterday's record highs in parts of Montana. A Dense Fog Advisory for the northern Sacramento Valley is in effect until 10 am PST.
Midwest:
The Alberta Clipper will bring widespread precipitation including light rain, snow and freezing rain across the Northern Plains and Upper Midwest. High temperatures will vary widely, from the upper 20s over northeast Wisconsin and lower Michigan behind the cold front to near 70 in Kansas from gusty southerly winds.
South:
Under high pressure, much of the region will be partly cloudy with little or no weather except for a few light showers over parts of the coastal Carolinas and the central coast of Florida.
Northeast:
A series of low pressure troughs moving over the region will produce widespread cloudiness and snow showers from the Appalachians to northern New England. Significant accumulations (5 to 9 inches) are expected in the usual areas - east of Lakes Erie and Ontario. (NOAA, National Weather Service and Various Media Sources)
During periods of dense fog the California Highway Patrol runs traffic breaks and pace cars on major highways to help slow traffic when visibility drops below 500 feet. Message signs provide information on changing conditions. (NOAA National Weather Service, FEMA Region IX)
