It looks like our monsoon season started really early this here in Tucson. We started getting some clouds moving in last night and I thought is monsoon season going to start early? It officially starts June 15 but we usually don't get rain until the start of July. It's been pretty cloudy today and I went outside and I could smell a change in the air, not quite monsoon rain.
Just a little while ago we heard thunder, and on twitter someone in the Tucson area, reported hail and tweeted a picture if it hitting their backyard.
I just stepped outside and definitely could smell the rain. And a litle while later the skies opened up. It rained pretty hard for about 10 minutes then died off.
Note: We've had an unusually wet and slightly cooler year so far, though this past week we had some record temperatures. You've heard the expression for March, "In like a lion. Out like a lamb." There should be one for June in Tucson. "In like an oven. Out like a steamer."
