Mean upper troughing will persist east of the Rockies for the Day 4-8 period. This will largely suppress northward transport of Gulf moisture, except periodically across the southern Plains and Southeast/Gulf coast states. Severe potential is expected to be low on Day 4/Fri as surface high pressure dominates in the wake of a prior cold frontal passage offshore the Gulf and Atlantic coasts. On Day 5/Sat, lee troughing will allow for increasing south/southeasterly low-level flow across the southern Plains and Lower MS Valley, aiding in moisture return across these areas. This could result in thunderstorm potential across the south-central U.S., but severe potential is limited given a lack of stronger forcing for ascent. By Days 6-7/Sun-Mon, another cold front is forecast to move east/southeast across much of the U.S. east of the Rockies. As the front impinges on a moist airmass across the southern Plains to the Southeast and Mid-Atlantic, some severe potential could develop. However, mid to upper-level flow is not forecast to be overly strong and medium range guidance varies quite a bit with respect to moisture and cold front timing, resulting in low predictability. ..Leitman.. 05/05/2026 = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
