Memorial Day weekend weather: severe storms in Central US, Northeast chill, and Southwest heatwave

Severe storms and heavy rain in the Central US
The central United States is currently under threat from severe weather and heavy rainfall. A slow-moving frontal system is bringing showers and thunderstorms, with the potential for flash flooding in areas from the Lower Mississippi Valley into the Southern Appalachians. The National Weather Service has issued a Slight Risk (level 2/4) of excessive rainfall in these regions, warning of localized flash flooding, especially in urban areas and low-lying regions.

Cool temperatures persist in the Northeast and Mid-Atlantic
In contrast, the Northeast and Mid-Atlantic are experiencing unusually cool weather. A broad mid to upper-level vortex centered across eastern Canada is supporting this cold pattern, with temperatures remaining below average. Highs are mainly in the 50s and 60s, particularly in the Ohio and Tennessee Valleys. Early morning frost is possible on Saturday from the upper Ohio Valley to the central Appalachians.
