A tranquil weather pattern is expected to continue into the start of Memorial Day weekend. Temperatures should remain seasonably mild with a blend of sunshine and passing clouds. At this time, no significant storm systems appear likely. • High: 73–77°F | Low: 52–56°F | Wind: SW 5–15 mph • Sky: Partly sunny • Precipitation: 10%
High pressure building into the Northeast should provide another pleasant day with moderate temperatures, lower humidity, and a good deal of sunshine. Overall, this looks to be one of the more comfortable days of the forecast period. • High: 72–76°F | Low: 50–54°F | Wind: NW 5–15 mph • Sky: Mostly sunny • Precipitation: 10%
Conditions begin trending more comfortable behind the departing cold front. Temperatures will settle closer to seasonal averages with a refreshing drop in humidity. A lingering morning shower cannot be ruled out, but much of the day should feature improving conditions and partial sunshine. • High: 75–80°F | Low: 54–58°F | Wind: WNW 10–15 mph • Sky: Partly sunny • Precipitation: 20%
Another very warm day is likely ahead of an approaching cold front. Temperatures may again approach 90 degrees, while rising humidity levels will make it feel even warmer. By afternoon or evening, scattered showers and thunderstorms could develop as the front moves closer to New England. Some storms may become locally strong depending on how much sunshine develops during the day. • High: 86–91°F | Low: 64–68°F | Wind: SW 10–20 mph • Sky: Partly sunny • Precipitation: 40%
Strong sunshine, southwest winds, and an increasingly warm air mass aloft could allow temperatures to surge into the lower 90s during the afternoon. Humidity levels will also begin increasing, giving the day a more midsummer-like feel. Aside from a very isolated late-day shower risk well north or west of the area, dry conditions are expected. • High: 89–92°F | Low: 66–70°F | Wind: SW 10–20 mph • Sky: Mostly sunny • Precipitation: 10%
Warm air continues building into the Northeast, although some coastal communities may be tempered by a developing onshore flow. Waltham should remain firmly on the warmer side of that boundary with temperatures pushing well into the 80s under a mix of sunshine and scattered fair weather clouds. • High: 84–88°F | Low: 60–64°F | Wind: SW 10–15 mph • Sky: Mostly sunny • Precipitation: 0%
A beautiful late spring day is expected with abundant sunshine, low humidity, and temperatures climbing well into the 80s during the afternoon. Westerly breezes may occasionally gust over 20 mph, but overall conditions will feel more like late June than mid May. • High: 81–85°F | Low: 56–60°F | Wind: W 10–20 mph gusting 25 mph • Sky: Sunny • Precipitation: 0%
A warming trend develops heading into next weekend with more sunshine returning. While most of the day looks dry, a brief passing shower cannot be completely ruled out. • High: 71–74°F | Low: 52–55°F | Wind: SW 10–15 mph • Sky: Partly sunny • Precipitation: 20% chance brief showers
The steadiest rainfall exits, though lingering clouds and a few scattered showers remain possible as cooler air aloft lingers over New England. • High: 64–67°F | Low: 47–50°F | Wind: WNW 10–15 mph • Sky: Mostly cloudy with some breaks of sun • Precipitation: 30% chance scattered showers
