The computer models are suggesting that this coming week will be the most exciting meteorologically in months. The main culprit is a midlatitude upper-level trough that will develop along the west coast over the next couple of days. First it will toy with the remnants of Hurricane Paine and bring a pronounced monsoon surge into the southwest (missing us though).
Then, as the trough amplifies and migrates eastward, a major precipitation event will develop over much of the interior west with showers, thunderstorms, frontal precipitation, and the like. Very interesting!
The pattern above suggests a very active period later in the week with the bottom falling out temperature wise. We haven't seen anything like this in months and will take a closer look as the system approaches.
