Man, and I thought I was bad complaining ably getting 5 inches instead of 6.

Not complaining just an observation.  It just a very weird thing that happens here.  We struggle mightily to reach 90 even on days forecasted for well above 90.

I will complain though about this never ending storm.  Very annoying.

Someone is going to have some pretty serious flooding on the south hills.

 

actually more like right in the city. I hope you guys that complain about not getting destructive weather have had your fill.

This summer has been incredible. Tons of storms, lots strong to low-end severe, very limited destruction so far. No ridiculous prolonged heat. A below normal July with no 90s.

This may be a historic night of thunderstorms. I have had 4 different storms go through in the last 2 hours. This line moving back north has strong winds and intense lightning. Worse than the other storms. Flooding will be an issue. 

Yeah, this is absolutely ridiculous.  Hope the destructive weather lovers are happy.

I like thunderstorms. Nobody on here likes destructive weather as you call it. The line is weakening. General thunderstorms now moving through. 

Sitting on my porch drinking a beer. Steady rain with thunder and crickets. Great sleeping weather too. Can’t beat it. 

Mmmmm...there are severe storm rooters around here.
