Deep upper-level trough will shift from the central US to the Tennessee Valley over the next 24 hours and a strong cold front will slide slowly to the east in this same time period. Low pressure along the frontal boundary zone will help to generate some heavy rainfall today from the Ohio Valley southward to the northern Gulf region and there will be the threat for some severe weather in much of the Southeast US including Alabama and Georgia. The cold front will slide across the region by early Friday and usher in a cooler air mass for the end of the week and upcoming weekend. One reminder, it is time once again to turn the clocks back this weekend early on Sunday morning.

Low pressure will form along the strong cold front in the central US and vigorous upper-level support will combine to help to generate a significant precipitation event from later today through Thursday in the region from the Rockies to the Ohio and Tennessee Valleys. Severe weather could also get involved with this unfolding pattern on Thursday across much of the southern US including here in northern Alabama.

A strong cold front will slowly push across the nation over the next few days and it’ll have an important impact on a wide area from the Rockies to the eastern seaboard. A powerful digging jet stream in the upper atmosphere will help to carve out a deep upper-level trough by late in the week and the result of this overall unfolding weather pattern will be heavy snow across the Rockies, heavy rain in the Ohio and Tennessee Valleys, and a severe weather threat across much of the southern US. Rain will spread into the eastern US by Thursday night as the front continues to slide slowly to the east. The rain will likely continue into Friday night in the eastern US - possibly heavy at times - as low pressure forms along the frontal boundary zone.
