A broad high pressure system will bring above-normal temperatures back to the Institute this week. With its center to our south, the high pressure system will bring clear skies and offshore winds to the Boston area for the next few days. Temperatures will near the 90°F (32°C) mark today as 10 mph westerly winds will keep cooler ocean temperatures literally at bay. Temperatures over the weekend will be slightly cooler as cloudiness increases ahead of an incoming cold front. The frontal passage will likely occur sometime on Sunday, ushering in a much colder start to the week on Monday. After the cold front passes, another high pressure system is expected to move in, resulting in a return to sunny skies for at least the first part of next week.
