Weather Underground Forecast for Tuesday, April 28, 2015
A low pressure system will affect the Gulf Coast on Tuesday, while a cold front will slide across the Northwest.
An area of low pressure will shift eastward over the central and eastern Gulf Coast. As this system draws moisture from the Gulf of Mexico, strong to severe thunderstorms will develop across the Gulf Coast, the Deep South and the Southeast. Severe thunderstorms will be possible in southeast Louisiana, southern Mississippi, southern Alabama and the Florida Panhandle. These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. Scattered showers and stray thunderstorms will also trail this system over parts of the southern Plains. Additionally, temperatures are expected to be 15 to 30 degrees below normal over the southern Rockies and the southern high Plains.
Meanwhile, an Atlantic system will linger several hundred nautical miles east of New England. This system will continue to usher light rain over New England and Upstate New York on Tuesday.
Out west, a weak cold front will shift eastward over the Pacific Northwest. This frontal boundary will generate light to moderate rain across Washington, Oregon and northern California. A ridge of high pressure over the eastern Pacific will keep conditions warm and dry across the Southwest. Temperatures are forecast to range between the 80s and 90s across the Desert Southwest on Tuesday.
