Weather Underground Forecast for Tuesday,February 23,2016

An area of low pressure will slide across the southern tier of the country on Tuesday, while a ridge of high pressure builds over the Southwest.

A low pressure system will strengthen as it moves eastward across the southern Plains and the lower Mississippi Valley. This system will draw copious amounts of moisture from the Gulf of Mexico, which will lead to heavy rain and strong to severe thunderstorms. Severe thunderstorms will be possible in extreme eastern Texas, Louisiana, Mississippi, Alabama and the Florida Panhandle. These storms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. In addition, heavy rain could lead to flash flooding in northern Louisiana, Arkansas, northwest Mississippi, western Tennessee, western Kentucky and southeast Missouri. Thunderstorm activity will also spread across the Tennessee Valley, the southern Ohio Valley, the southern Mid-Atlantic and the Southeast.

The same system will interact with a cooler air mass, which will lead to the development of mixed precipitation across the central Rockies, the central Plains, the middle Mississippi Valley and the upper Midwest. Freezing rain will also be possible across the eastern Great Lakes and portions of the Northeast.

A ridge of high pressure over the eastern Pacific will keep conditions dry across the Southwest. Offshore winds will lead to above normal temperatures across southern California.
