PHOENIX -- According to the calendar, the monsoon season isn't over since the season extends until September 30. But the question is will be seeing any more storms?

Probably not many. It's been a crazy summer.  We had a week in mid-July where we had a bunch of rain. However, we've only had .01" since July 25.

And while it's not unusual to have a few breaks from the thunderstorms, the dryness of the atmosphere has been incredible for the summer. We've had dew points in the 20s and 30s quite regularly. That's supposed to happen in the fall.

It won't end up being the driest monsoon. That occurred for Phoenix in 1924 when the city received only .35" of summer rain. So far this year we've had a respectable 1.77" of rain, all of it coming during that one week in July.

So what to expect for the rest of the summer thunderstorm season? Probably more of the same…..lots of dry air and then, for maybe a week later this month or early next, we'll get a frenzy of thunderstorms in and around the Valley.  After that, the monsoon may be over.

For the end of this week and weekend, things are picking up a little bit.  However, even the National Weather Service has no more than a 20 percent chance for rain on Sunday, with a 10 percent chance Friday and Saturday.
