The weather over the next week can be summed up pretty distinctly…Hot and dry. A ridge of high pressure will strengthen boosting our Tuesday high temperature into the mid-80s, followed by the mid-90s from Wednesday through the end of the week. All that heat may allow some afternoon pop up cumulus clouds to build up, but overall the airmass looks quite stable, and at this time I don’t expect to see any storm development.

pole reversal

A while ago I mentioned that the earth’s magnetic field will flip over every so often, on average every quarter million years or so. Barbara wondered: “I don’t understand what it means for the magnetic poles to reverse. I know that our weather doesn’t suddenly turn from summer to winter as that is dependent on the inclination of the poles; but do all the compasses suddenly start pointing in the opposite direction?  If not, how do you know the poles have reversed?”

It’s not a physical flipping over of the earth… it just has to do with magnetic north switching with magnetic south. As you know, magnets have a north and south pole… for some reason over geologic time these flip for the earth’s magnetic field. More tomorrow.
