Overview
- Weather models show a broad early‑summer setup of warm, humid air and daily afternoon or evening isolated to scattered showers across many regions.
- Minnesota faces the highest immediate storm risk with roughly a 70% chance of scattered storms Tuesday and a few cells capable of becoming strong to severe with hail.
- The Southeast and Lowcountry are seeing low‑to‑mid 90s for highs with feels‑like readings in the upper 90s to triple digits, and some forecasts say heat indices could approach or exceed 105°F later this week.
- A weak frontal passage will briefly lower humidity and bring a few more comfortable, drier days to parts of the Southeast and the Susquehanna Valley before heat and humidity rebuild.
- Forecasters say the pattern is likely to strengthen into next week with more widespread heat, temperatures climbing into the upper 80s and 90s, and a growing chance of the season's first heatwave in some areas.
