Overview
- A compact storm produced multi-inch rainfall and localized flooding on Cape Cod and the islands, with reports of three to six-plus inches and street flooding in Falmouth and Mashpee.
- The system slowed evening travel on Massachusetts’ south coast and left wet roads through the commute while Boston and inland areas saw lower totals.
- The same low-pressure area only brushed Maine, where the coast had light showers, patchy overnight fog, and daytime highs held in the 70s under a sea breeze.
- Meteorologists say most rain should taper toward midnight with clearing on Wednesday, then temperatures and humidity will climb Thursday into Friday with highs near 90°F and elevated heat-index values.
- A frontal passage may trigger thunderstorms Friday before humidity and temperatures fall for a sunnier, less humid weekend, and forecasters will refine the exact timing of Friday’s storms as models update.
