Overview
- The week begins dry and comfortable under a broad area of high pressure with low humidity and seasonable highs for Monday and Tuesday.
- Forecasts from multiple local offices show temperatures climbing into the upper 80s and 90s by Wednesday and Thursday as warmer air and higher dew points move north.
- Daily chances for scattered to numerous afternoon and evening thunderstorms will expand later in the week and these storms can produce intense short‑duration rainfall that creates localized flash‑flood and urban‑flood threats.
- Coastal and lakeside communities should expect cooler conditions thanks to onshore and lake breezes while inland areas face higher heat‑index values that may reach triple digits in spots.
- The Southwest will remain dry under the ridge of high pressure, keeping drought and elevated fire danger in place even if late‑week storms bring isolated downpours elsewhere.
