Weather Underground Forecast for Tuesday, February 07, 2012. A Pacific storm will slam into the West Coast Tuesday, bringing much-needed rain and some high elevation snow to California. It has been a very dry Winter for many areas of the countries, particularly in California where most areas are far below their normal precipitation levels. While this new storm will not be a very wet system, it will bring precipitation to many areas of the state from Eureka through San Diego. Rain will turn to snow in the higher elevations of the Sierra Nevadas, an area also in need of Winter precipitation.

Meanwhile, leftover showers and thunderstorms will diminish in south Florida as a rare February tropical disturbance continues to move out into the Atlantic Ocean.

A cold storm will progress through the Plains, but it will lack significant moisture that would make it a major storm. Instead, it will act to cool afternoon temperatures from the Dakotas to Oklahoma. A few snow showers are possible in the Central Plains to Illinois.

The Northeast will be cool but dry, as has been the case for much of the Winter.

The Northeast will rise into the 20s, 30s, and some 40s, while the Southeast will see temperature sin the 60s, 70s, and some 80s. The Northern Plains will rise into the 10s, 20s, and 30s, while the Northwest will see temperatures in the 40s and 50s in the lower elevations.
