Timing and rainfall
Showers are possible around midday with a greater chance of showers and thunderstorms developing later in the afternoon. Localized rainfall totals are forecast to be in the range of 10 to 20 mm in the heaviest cells. Forecasters also note a risk of a thunderstorm close to noon.

Health and safety guidance
- Heat and humidity: those sensitive to heat — older adults, young children, and people with chronic conditions — should limit strenuous activity during the warmest and most humid parts of the day.
- Thunderstorms: secure loose outdoor items and avoid travel if visibility is reduced by heavy rain. Move indoors at the first sign of thunder or lightning.
- Driving: expect sudden changes in road conditions during downpours; reduce speed and allow extra stopping distance.
UV levels will be elevated later in the afternoon with an index of about 6 (high), so sun protection is recommended whenever skies clear. Forecasts indicate drier and sunnier conditions on Monday, with temperatures returning to the mid- to high-20s the next several days.
Updates will be issued as conditions evolve; consult local weather services for any short-term watches or warnings affecting the Cambridge area.
