Weather-- Record Rain Reigns
Record Rain ReignsBy Gerard Roe
The 7.9 inches of rainfall recorded at Logan Airport over the weekend was the largest 24-hour total in October and the second greatest ever on record. Only Hurricane Dianne in 1955 with 8.4 inches in a single day has bested this storm's total.
The situation occurred because of an unusually large blocking high pressure sitting over Quebec. This means the rather intense storm, centered in the upper troposphere, is not pushed anywhere very fast and just hangs around making everybody miserable. This fact, combined with a helping hand from Hurricane Lili in the form of a shot of tropical moisture, created the huge rainfall amounts.
The system continues to plague us as it drifts very slowly north and east, with plenty of moisture and an unsettled atmosphere. A weak warm front passing through the area toward the evening may well be the focus for some scattered showers but will be of much diminished intensity compared to Sunday. Some clearing overnight and on Wednesday morning heralds a brief respite, but another large cyclone is gathering in the Midwest and can be expected to menace the area later in the week.
Today: Patchy fog in the morning. Scattered showers possible through the evening, but any precipitation will be light. Cloudy, for the most part but with some breaks expected. Light winds and variable in direction. High 59°F (15°C).
Tonight: Initial chance of scattered showers, then clearing up. Low 46°F (8°C).
Wednesday: Clear early with winds out of the south. High clouds, then becoming overcast toward evening. Chance of overnight showers. High 63°F (17°C). Low 48°F (9°C).
Thursday: Unsettled, with rain possible. High about 60°F (16°C). Low around 40°F (4°C).
