With a storm track that is running along the US-Canadian border and a broad ridge of high pressure across the southern US, the weather pattern isn’t likely to change dramatically anytime soon. Temperatures will rise into the 90s and stay there throughout the rest of the week. Winds will be light in the morning hours, with afternoon “Washoe Zephyr” winds coming up out of the west in the 10-15 mph range.

Elliptical orbit

Here’s why sunsets don’t get later for a couple of weeks after the solstice: Right now we are just about at the furthest point out from the sun, and as a result we are moving around the sun at the slowest speed. Every day, the earth spins one full rotation PLUS 1/365th of a rotation to make up for how far the earth has orbited the sun (we keep our days straight with respect to the sun’s position relative to the earth). That means that every 24 hour period this time of year we over-rotate a bit a bit since we are travelling a little less around the sun during that 24 hours. (I’ll finish tomorrow.)
