Overview
- Broad high pressure is in control early this week, producing dry, low‑humidity weather and highs in the 70s to low 80s across many eastern and central areas.
- Southerly winds later this week will raise temperatures into the 80s and upper 80s with some spots near 90°F and noticeably higher humidity by Friday.
- Forecast models agree on a frontal system that will increase shower and thunderstorm chances late Saturday into Sunday, though the exact timing and coverage remain uncertain.
- Localized severe risks are possible if instability and the front align, with areas of concern including eastern Montana and parts of the Plains and Midwest where gusty winds, large hail, or heavy rain could occur.
- NOAA and Colorado State University predict a below‑normal 2026 Atlantic hurricane season, and drought‑stressed pockets in the Northeast stand to benefit if the weekend rain materializes.
