Mother’s Day looks improved overall with a mix of clouds and some sunshine developing. However, enough moisture lingers in the atmosphere for an isolated afternoon shower or thunderstorm. • High: 71–74°F | Low: 54°F | Wind: SW 10–15 mph • Sky: Partly sunny • Precipitation: 30% chance isolated showers
Early indications suggest somewhat improved conditions, though an isolated shower cannot be ruled out depending on how quickly the late-week system clears. More breaks of sun are possible. • High: 68–71°F | Low: Low to mid 50s | Wind: W 8–12 mph • Sky: Partly sunny • Precipitation: 20–30% chance isolated showers
Unsettled weather may linger as the frontal system slowly exits. Some showers remain possible, though there should also be dry periods mixed in. Temperatures stay mild. • High: 70°F | Low: 55°F | Wind: W to SW 8–15 mph • Sky: Mostly cloudy • Precipitation: 40% chance showers
A frontal boundary approaches, increasing the likelihood of scattered showers and more widespread cloud cover. While not necessarily a washout, this appears to be one of the wetter days of the stretch. • High: 71°F | Low: 54°F | Wind: S to SW 10–15 mph • Sky: Mostly cloudy • Precipitation: 50–60% chance showers
Warmth persists with another day well above average, though humidity and cloud cover gradually increase. A few showers may arrive later in the day or overnight. • High: 76°F | Low: 58°F | Wind: SW 10–15 mph • Sky: Partly sunny becoming mostly cloudy • Precipitation: 30–40%
A strong southwest flow develops, pushing temperatures into the upper 70s. Breezy to windy conditions are likely, but most of the day stays dry aside from a slight late shower risk. • High: 77°F | Low: 56°F | Wind: SW 15–25 mph, gusts 30+ mph • Sky: Partly sunny • Precipitation: 20%
The weekend system pulls away, allowing drier air and increasing sunshine to return. Breezy west winds and moderating temperatures make for a much more comfortable spring day. • High: 69°F | Low: 48°F | Wind: W 10–20 mph • Sky: Partly to mostly sunny • Precipitation: 10%
A coastal low passing southeast of New England keeps Waltham on the northern edge of the system. While the heaviest rain should stay southeast, periods of light rain or showers remain possible, especially in the morning. • High: 61°F | Low: 44°F | Wind: NE to N 10–15 mph • Sky: Cloudy • Precipitation: 40% chance light rain
Partly sunny and seasonable with just a low chance of a leftover shower. • High: 60–65°F | Low: 45-50°F | Wind: W/NW 10–15 mph • Sky: Partly sunny • Precipitation: 20%
A few showers may linger, but there should also be some dry periods. • High: 62–66°F | Low: 48-52°F | Wind: W/SW 10–15 mph • Sky: Partly to mostly cloudy • Precipitation: 30%
