6/23/2018 7:00 AM 0.79 M M M M Severe thunderstorm between roughly 2215-2300. Wind gusts to about 60mph, no hail. More storms later in the night but not severe.
6/24/2018 7:00 AM 1.00 M M M M Exactly 1 inch of moisture with this convective system that rolled thru between 0330-0600. Not quite as severe as the storm the night before but still 40 mph winds or so, no hail that I'm aware and an average amount of lightning. More storms close by at the time of observation which was at 0730.
6/25/2018 7:00 AM 2.54 M M M M What was likely the last in a series of late night convective complexes rolled thru with borderline severe wind gusts (50-55mph) a fair amount of lightning, bountiful rainfall and a few pings of small hail on the windows. Storm was from roughly 0200-0500. Still light rain with occasional IC lightning at observation time at 0745.
7/1/2018 7:00 AM 0.37 M M M M .32 in storms around mid afternoon, then thundershowers ongoing at observation time giving additional .05 so far until 0700.

Initial gust front had 40-50mph gusts, but the main action was towards the back side of the core where winds gusted to around 70mph around 0300. Rainfall rates were impressive; up to 5"/hour. No hail that I was aware. Lightning was not overly noteworthy; mostly in cloud with an occasional CG. Thankfully, it was no worse than expected.

8/8/2018 7:00 AM 2.07 M M M M Close to severe thunderstorm around the 0230 timeframe. Considerable CG's; some close. Highlight was strong wind gusts from the east which then veered south at 45-50mph. More storms afterwards but not as strong; lightning continued in abundance. This rain alone will really green things up now.
