As I have mentioned before, and shown on my Monsoon Mechanics Website, the location of high pressure in the southwest. Over the last few days, we have had southwesterly to westerly winds. This is due to the drift
But, starting this weekend, high pressure will develop to southeastern Arizona. This will put us back in the moisture stream. It will take a couple days for it to make it here. By Tuesday or Wednesday, we should see more thunderstorm activity.
It looks like it could be a pretty good puff of moisture we get. Here is the water vapor image from this morning.Notice the effect of the southwesterly flow bringing the dry (orange) air to Arizona.
There is plenty of moisture available, we just have to get it to Flagstaff. But, for this weekend, ENJOY!!! This could be the most beautiful weekend of the summer.
