A very active weather pattern is forecast to continue across the central part of the nation through the end of the week, NWS warns.
This is in response to an anomalous upper level trough situated over the Intermountain West and a large upper level ridge anchored over the southeastern U.S.
A clash of air masses from the southern Plains to the Ohio Valley region will support multiple episodes of bad weather in the general vicinity of a slow-moving frontal boundary with waves of low pressure developing along with it.
The first of these surface lows will cross the Great Lakes region on Thursday, May 23 and bring a cool front to the East Coast by Friday morning. In the warm sector of this low, severe thunderstorms will be possible from the Ohio Valley to the Mid-Atlantic and Northeast on Thursday.
After some lingering showers across New England on Friday, expect better conditions across the northeastern quadrant of the nation to end the work week, with slightly cooler conditions and lower humidity compared to Thursday.
The second low pressure system develops across the western High Plains Thursday night and lifts northeastward across the Upper Midwest by Friday evening, May 24. A corridor of enhanced rainfall along with severe weather is likely from the Texas Panhandle to Wisconsin over the next couple of days.
Flash flooding is possible across portions of the central plains during this time, and SPC has an enhanced risk of severe storms from northwest Texas to central Kansas on Thursday.
