Last night around 9 PM EDT, we experienced a deluge of rain during a severe thunderstorm. Our automatic tipping spoon recorded the second highest rain rate in the 8 years we’ve been online (10.7″/hr). Overall, we picked up just over 1.5″ of rain in half an hour with about 1″ falling in the first 15 minutes of the storm.
We clocked a 37 mph wind gust during the storm. However, each wind measurement must last up to 2.5 seconds to be recorded by our system. It’s quite possible higher, shorter-lived winds were present during that storm as radar had indicated up to 60 mph gusts according to the severe thunderstorm alert issued by the National Weather Service.
There was lightning aplenty but no hail. We got quite the hail storm on Saturday July 22nd. The entire property was coated with pea size pellets.
Marquette is running WELL above normal for July rainfall. So far 4.89″ has been recorded by our automatic gauge (which is checked against a manual gauge daily). Marquette’s 30-year normal rainfall for July is 2.77″.
Incidentally, the third highest rain rate in our history (9.75″/hr) was recorded less than two weeks ago on July 15th when we picked up 0.64″ for the day.
