Overview
- Heavy, localized rain bands on Sunday produced Flash‑Flood risk and Flood Watches across southern New England, with narrow pockets receiving 2–4 inches in a few hours and reports of flooding in parts of Bristol and Plymouth counties.
- The same frontal system brought cooler, drier air to parts of the Upper Midwest and Northeast, creating a short 'temperature roller coaster' for the Chicago area with lows dropping into the 60s after recent warmth.
- Dangerous heat persisted across the South, where Houston and Central Texas faced Heat Advisories with feels‑like temperatures near 110°F and Northeast Florida/Southeast Georgia saw heat indices around 102–105°F plus strong storm gusts and frequent lightning inland.
- Scattered showers and isolated thunderstorms will continue through the next 48 hours with gusty post‑front winds possible (up to about 30–50 mph in some spots), while models show a rebuilding upper‑level ridge that could return summerlike warmth to inland areas by midweek.
- The Atlantic basin is broadly quiet for the next seven days, but short‑range forecast uncertainty means local National Weather Service offices should be consulted for flash‑flood warnings, heat‑safety guidance, coastal rip‑current alerts, and any rapid changes to the midweek outlook.
