A mostly sunny, seasonable weekend is in store after two consecutive days of above-average temperatures. Yesterday’s high temperature at MIT was 73°F, well above the mean value of 61°F normally recorded at nearby Logan Airport. Likewise, southerly winds will keep a warm, moist air mass in place early this morning, allowing temperatures to approach the 70-degree mark for the second day in a row. This time, however, a cold front will pass through the area during the morning hours, resulting in increased windiness, a drop in humidity, and the arrival of cooler air from our north and west. That cooler air mass will continue to move in over the next couple of days, creating the a more seasonable weather pattern, with highs near 60°F and lows around 45°F by the beginning of next week.
Some showers will be possible on Saturday night and Sunday morning with the passage of a weak disturbance through the area. For the most part, however, the weekend will be pleasant, with a relative abundance in sunshine. The same could not be said for this weekend in 1770, when a hurricane struck Boston, causing the city to record its highest tides in 47 years.
