A front extending from Northern Mid-Atlantic to the Middle Mississippi Valley into the Northern Plains will move off Northeast Coast by Tuesday evening and off most of the Southeast Coast/Gulf Coast by Wednesday. Farther to the south, an upper-level trough has provided a triggering mechanism for scattered showers and thunderstorms for the past few days across the Deep South. Southerly flow ahead of the upper trough will begin to bring tropical moisture from the Gulf of Mexico into the Southeast including Florida for the next few days. An elongated low pressure system is forecast to form in the northern Gulf and reach the Florida Panhandle by Wednesday morning. Widespread showers and thunderstorms can be expected to continue into Wednesday from across the Deep South into the Southeast and down the Florida Peninsula. Out West, a strong cold front is expected to bring showers and thunderstorms across the northern Rockies and into the northern Plains today. Some of the thunderstorms could become quite strong. The front will continue to move steadily eastward across the northern and central Plains on Tuesday, bringing more showers and thunderstorms. By Wednesday, thunderstorms should reach the southern High Plains. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
