Weekend Weather Spotlight: 4-23-21

Three systems will be tracked through the weekend affecting the country producing heavy rain, some snow accumulations, and severe weather as well.

The first system, the strongest and most impactful one will move from the Southern Plains today, through the Southeast and Mid-Atlantic Saturday, and lingering effects early on Sunday still for northern parts of the Mid-Atlantic and parts of New England. The main story will be the severe weather and heavy rain potential today and tonight for parts of the Southern Plains and lower Mississippi River Valley, and in parts of the Gulf Coast states and Southeast on Saturday. Shower and storm activity is expected to increase in coverage this evening and evolve into a large thunderstorm complex over the lower MS River valley tonight and will move through the Southeast and Mid-Atlantic Saturday and Saturday night. The severe potential will be in eastern TX and much of OK east through southern AR, much of LA, and southwest MS, and could get as far east as southwest AL this evening and overnight, and then develop on Saturday behind the large storm complex with chances from southeast MS to southern GA. All severe hazards will be possible in addition to heavy rain as widespread accumulations in the 2-4 inch range are possible from east TX to southern SC. 

The next system brings light rain and snow chances from the northern Rockies to the northeast with a couple of inches of snow possible in the northern Rockies today, and in the UP of MI on Saturday night. 

Finally, the last system affects areas from the west to the Upper Midwest with more rain and snow chances. Snow accumulations are likely in the mountainous regions, and there could be a swath of a couple of inches from parts of MT through the Dakotas and into MN Saturday night into Sunday.
