The nation's weather
Weather Underground Forecast for Saturday, Nov. 26, 2011.
Active weather was expected to return to the central U.S. on Saturday, as a low pressure system moved into the Upper Great Lakes. This system expected to pull a cold front eastward with it, which extended from the Upper Midwest, through the Mid-Mississippi River Valley, and into the Southern Plains. This system was expected to bring significantly cooler temperatures to the Upper Midwest, allowing for snow showers to return. Snow showers were expected to be light with accumulation around one to two inches. At the same time, the southern end of this front was expected to pull in ample moisture from the Gulf of Mexico, allowing for strong showers and thunderstorms to develop. These storms were expected to turn severe across eastern Texas and the Lower Mississippi River Valley. Rainfall totals will range from 0.50 to one inch, up to two inches in areas of severe thunderstorm development.
Behind this system in the West, cold air was expected to continue pouring in from western Canada, allowing for unseasonably cold temperatures across the Rockies and Southwest. Daytime highs will range in the 40s and 50s, with overnight lows dipping into the 20s and 30s. The Northern Rockies, however, were expected to see overnight lows near zero, with daytime highs in the 30s. Further west, high pressure continued building over California, which allowed for clearing skies and dry conditions. In the Northwest, a cold front pushed onshore from the Gulf of Alaska, bringing rain and high elevation snow to British Columbia and northern Washington. These showers were expected to reach into Oregon by evening. Temperatures in the Lower 48 states Friday ranged from a morning low of 12 degrees at Big Piney, Wyo. to a high of 86 degrees at Edinburg, Texas
