Overview
- Forecasters put parts of the southern and central Plains under an enhanced severe risk Wednesday, with the NWS warning of very large hail, damaging winds and a few tornadoes this afternoon and evening in areas including Oklahoma City and Wichita.
- A broad system is set to trigger thunderstorms across more than 30 states through early Thursday, with NOAA projecting 1 to 4 inches of rain for many areas and local totals near 6 inches that could spark flash flooding and river rises.
- Major Midwest and Ohio Valley metros face lower‑tier risks and tight timing windows, with Chicago and Milwaukee expecting a slight risk for strong storms Thursday, Cleveland dealing with lingering heavy rain Wednesday, and south‑central Pennsylvania bracing for evening thunderstorms.
- The UK Met Office issued yellow wind warnings from Saturday 6 p.m. to Sunday noon for Scotland, Northern Ireland and parts of northern England and Wales, citing gusts of 50–60 mph, 60–70 mph in exposed spots and up to 80–90 mph in western Scotland with risks to travel and power.
- Met Office guidance ties the UK threat to a cold plunge from Canada that strengthens the jet stream and deepens a low near northwest Britain, while in the U.S. the clash of Gulf moisture with cooler air is driving repeated storm rounds that add to already wet soils and flood risk.
