Overview
- Morning rain and fog on Memorial Day gave way to afternoon clearing and seasonable highs mostly in the 70s to mid‑80s across large parts of the country.
- Guidance now focuses on an elevated storm window Tuesday night into Wednesday driven by upper‑level energy and a front that could produce widespread showers and clusters of storms.
- Southern coastal areas, notably the Pine Belt and nearby coast, were singled out for training downpours with forecasters warning of 2–4 inches in 24 hours and the potential for flash and urban flooding.
- California contrasted with the rest of the nation as cooler onshore and Delta breezes kept valley highs in the upper 70s, produced gusts around 20–35 mph, and allowed isolated afternoon storms over the Sierra.
- After midweek rounds, forecasts shift toward a late‑week cooldown with renewed shower chances and continued spotty storms in humid southern zones, a pattern that could disrupt travel and outdoor plans.
