Dewpoints and thunderstorm activity have declined significantly through the week. Will the rains return? The National Weather Service says, “Yes.” And, maybe we will see a return to big storms and lots of rain. There is a nice moisture plume in Mexico that could have our name on it. Here is a water vapor image.
In this image, the orange have over the Pacific and parts of the Southwest is dry air. The gray areas are moister, with greens, blues and oranges over Mexico represent even greater moisture levels. You can load an animation here (It’s very cool). To me, it looks edgy. A little to the sides of this plume there may be nothing. Right now, they are saying it will hit Flagstaff and could hit hard, again. But, a little shift to the east or west could make a big difference.
Today could see a little more activity, with the weekend seeing much more activity.
