With the eastward movement of the low pressure center up in the Pacific Northwest, a ridge of high pressure will build back into the Great basin, keeping our skies clear and the temperature trend on the upswing. Look for valley highs to climb into the low 90s Thursday, the mid 90s by Friday and will fall just shy of the triple digit mark by the weekend. Light morning winds will give way to west breezes in the afternoons.
The Perseid Meteor Shower peaks late Thursday night/early Friday morning. The best way to catch them is to pretend that you are going out to view fireworks. That means leave the telescope at home. Go out and find an area away from the lights of the city, bring a couple of lawn chairs, and kick back and relax, looking generally to the east, although they can appear anywhere in the sky. And be prepared to lose some sleep, because they, like most all meteor showers, are better after midnight. Why so late? I’ve been asked that many times, and have always had a tough time describing why in print, but I’ll give it a shot. The reason for this has to do with the geometry of the earth and its orbit. I’ll finish up tomorrow.
