A chilly northeast flow will keep our temperatures well below average Tuesday, and an isolated shower isn’t out of the question (although it is unlikely). The low pressure center bringing in the cold air will more out of the region as the week goes on and temperatures will rebound as we go through the rest of the week. High temperatures Tuesday will top out in the upper 50s, but could reach 80 by the weekend.

We’ve been talking about the fall equinox, and just what the equinox denotes astronomically. But the term “equinox” might be a bit of a misnomer. The term “equinox” comes from the Latin meaning “equal night”. We generally think that on the first day of fall (at the equinox), the nights and the days are of equal length, and in a rough sense, that’s true. But if you check sunrise and sunset tables, you’ll find that the day (the time between the two) is about eight minutes longer than the night.

Tomorrow, I’ll tell you why they’ve tacked on those extra minutes.
