[Earth is in a stream of debris from Comet Swift-Tuttle, source of the annual Perseid meteor shower. Worldwide observers are reporting more than 30 Perseids per hour, a number that could have tripled when Earth reached the heart of the debris zone today. Meteor shower forecasters recommend looking during the dark hours before dawn when activity is expected to be highest. The meteor shower will continue for a few more days with fewer meteors visible per hour. Visit http://spaceweather.com for sky maps, observing tips, and links to a live meteor radar].

Advisories: NONE AT THIS TIME.

A high pressure ridge (“Arch” shape on brown line) has been building over us and will allow for another day of hot weather. The ridge will weaken Monday and Tuesday along with a weak cold front that will slide by mainly north of us by Tuesday not having any effect on our weather except to cool us down a bit and making us feel like the hot weather is over. The high pressure ridge will strengthen again for another round of increasing temperatures back to hot. [Earth is in a stream of debris from Comet Swift-Tuttle, source of the annual Perseid meteor shower. Worldwide observers are reporting more than 30 Perseids per hour, a number that could have tripled when Earth reached the heart of the debris zone today. Meteor shower forecasters recommend looking during the dark hours before dawn when activity is expected to be highest. The meteor shower will continue for a few more days with fewer meteors visible per hour. Visit http://spaceweather.com for sky maps, observing tips, and links to a live meteor radar].
