We are still looking at a warm and periodically cloudy Easter weekend. The ridge of high pressure over the west coast does flatten out a bit, but will still allow high temperatures in the low to mid-70s through the first few days next week. A couple of weak to moderate storms will move through the region late next work week, bring a chance of some valley rain and high mountain snow.
Lee wondered: “Do you know a definition for the Arctic Circle? I have heard two. One is it is above that latitude where the day and night is 24 hrs. The other is it north of the latitude where the hottest average monthly temperature is above 10 degrees.”
Basically, it is the southern extent of the theoretical “Polar Day”… or the farthest south you can go and still have 24 hours of sun at the summer solstice (or 24 hours of night at the winter solstice, called the “Polar Night”). It’s located at latitude 66.56083 degrees north. This is what you get when you subtract the tilt of the earth (23 degrees and change) from 90 degrees. And while the average monthly temperature is pretty chilly up there, it doesn’t factor in the definition of the Arctic Circle.
