Weather: Some Seasonal Statistics

By Nikki PrivÉ
STAFF METEOROLOGIST -- High pressure building over New England today will keep skies clear, but temperatures will remain a bit chilly for the season with highs only in the mid 50s F. A fast-moving low pressure system will push through Canada tomorrow, trailing clouds and showers into the Boston area on Saturday afternoon. The system should clear out quickly, with drier conditions on Sunday and Monday.

Although October got off to a warm start, temperatures for the past week have been relatively cool -- the average high temperature for mid-October is in the low 60s F (17°C). With the rapidly shortening day length, the average high temperature in Boston drops quickly during October and November, falling one degree F every 2-3 days. The average daily snowfall becomes measurable the first week of November, but the earliest measurable snowfall occurred on Oct. 10, 1979. The latest first snowfall of the winter occurred on Dec. 16, 1973, with the earliest trace of snow on July 10, 1955!
