An upper level low (Shaded “U” Shape with blue arrows) will be moving West to East north of us giving us some slightly cooler weather. It looks like a frontal system will be heading our way Thursday with very little or no effect on our weather. A warm front (line of red semicircles) pushes through between Friday and Saturday. A cold front looks like it will move through the Pacific Northwest next Monday. A high pressure ridge (“Arch” shape with blue arrows) takes over to bring more sunshine and warmer temperatures once again.

The upper level airflow will increase from the West today cooling us out of the mid 90s. It looks like a frontal system will be heading our way Tuesday with very little or no effect on our weather except to keep us a bit cooler. Another frontal system slides through the Pacific Northwest Thursday. You may just want to check out this year’s Perseid Meteor Shower which peaks through tonight. It is predicted that you could see up to 200 “shooting stars” per hour from debris from the comet Swift-Tuttle. Best viewing is late at night to before sunrise. Make sure you are out far enough away from the city lights so the sky looks darker and the meteorites will be more easily seen.

An upper level high pressure ridge (“Arch” shape in blue arrows) is bringing us sunshine and much warmer temperatures. A frontal system will be pushing through Oregon Sunday to cool us down a bit . It looks like another frontal system will be heading our way next Tuesday with very little or no effect on our weather. You may just want to check out this year’s Perseid Meteor Shower which peaks through Sunday. It is predicted that you could see up to 200 “shooting stars” per hour from debris from the comet Swift-Tuttle. Best viewing is late at night to before sunrise. Make sure you are out far enough away from the city lights so the sky looks darker and the meteorites will be more easily seen.
