WASHINGTON, D.C.-- The National Weather Service's Climate Prediction Center (CPC) is predicting a dramatic change in weather patterns in the eastern third of the U.S. over the next four to five days. CPC forecasters anticipate the possibility of severe weather and possible flooding in some areas. The primary weather-maker for the period Feb. 12 - 19 will be the storm now moving out of the Central Plains as it clashes with the warm air ahead of it. Along with the threat of severe weather, some areas may see heavy precipitation amounts of 1 to 2 inches of rain, and locally heavier amounts.

Areas of particular concern for possible flooding include the Ohio and Mississippi River valleys. As the system moves to the east, areas from the Great Lakes to southern Maine will see a dramatic change from spring-like thunderstorms to flurries and the possibility of significant lake-effect snows.

For the Pacific Northwest, CPC models indicate one more vigorous storm beginning today and running through Saturday. The storm will include extremely high winds along the coastline and rain and snow in inland areas, depending on elevations. In the wake of this storm, the strong northern jet stream is expected to weaken, bringing more settled conditions to this windblown and saturated region.
