Weather Underground Forecast for Tuesday, November 20, 2012. A strong Pacific storm will continue moving inland through the Northwest and Northern Rockies on Tuesday. Rain and high elevation snow is likely for Washington, Oregon, and Northern California before the storm moves into Idaho and western Montana. This storm will be reinforced by another Pacific storm in the afternoon and evening that will allow precipitation to continue through the Northwest throughout the day. In addition to the precipitation, gusty wind to 65 mph is expected for the area. The strongest wind will blow through the higher elevations of the Cascades.
By the end of Tuesday, rain will reach as far south as the San Francisco Bay Area, with high elevation snow moving into the Sierra Nevadas of California.
Much of the rest of the country will experience dry conditions as a high pressure ridge moves into the Plains. The one exception to this may be in the Great Lakes as a weak cold front could bring light morning rain.
The Southeast will rise into the 60s and some 70s, while the Northeast will see temperatures in the 40s and 50s. The Upper Midwest will rise into the 40s and 50s, while the Northwest will see temperatures in the 30s in the higher elevations, 40s and 50s elsewhere.
Temperatures in the Lower 48 states Monday have ranged from a morning low of 1 degrees at Springfield, Vt. to a high of 82 degrees at Weslaco, Texas
