Boston Weather: 40.0°F | A Few Clouds and Breezy

Weather: Weather More Rest from the Heat

By Michael J. Ring
STAFF METEOROLOGIST -- In a refreshing change after a stifling week of heat and humidity, yesterday’s temperatures and dewpoints were well below normal values for early August. The next few days will continue to feature respite from the sweltering weather.

Last week’s heat wave was remarkable not for extremely high temperatures but for its duration. Temperatures in most locations reached the low 90s F each day last week, which is about 10°F above normal late July/early August highs. Record daily temperatures for this time of year, though, hover near 100°F, so few daily records were broken last week.

But many sites in southern New England recorded 90°F or greater highs for eight consecutive days -- an unusually long streak for this area, where heat waves usually break after three or four days. In fact, the National Weather Service reports that the recent eight-day streak of 90-degree-plus weather at Windsor Locks, Connecticut tied for that town’s third longest heat wave on record.

The fans of heat and humidity will have to wait a few days until their favorite weather returns. While highs will remain well below 80°F today and tomorrow, a southwesterly flow expected to form later in the week will bring warmer and more humid weather back for the weekend. However, temperatures and dewpoints over the weekend should not reach last week’s oppressive levels.
