5/8/2019 7:00 AM 3.26 M M M M This ob was taken at 0840. Based on radar loops, rainfall amounts since 0700 may have been inconsequential. Bulk of the storms moved in around close to midnight. Storms remained sub severe (at least when I was awake until 0230) CG's were active at times, no hail was noted and highest winds at most 45mph. I think we're okay on the rain for now.

5/14/2019 7:00 AM T M M M M Early evening thunderstorms skirted the farm from 1930-2030. Only a meager outflow boundary was noted here, but the storm was a pretty one with nice sculpture and in cloud lightning.

5/21/2019 7:00 AM 5.83 M M M M We were a little concerned about how yesterday would pan out, There was a visual of the meso with brief tornado touch downs about 8 miles to our west around mid afternoon with the first round of convection. Early evening around 2000CDT the rains started, nothing more than subsevere as far as wind and hail is concerned, heaviest of the rains occurred after midnight with repeated rounds of convection. Most noteworthy was the CG's, several striking uncomfortably close to the house. Have I mentioned we've had enough rain?

5/25/2019 7:00 AM 1.13 M M M M While a train echo of intense thunderstorms raked area's to my immediate west and north in the early evening, we stayed mostly dry until around 2000 hour, then thankfully with the second batch of convection that moved over us, it was a moderate soaking with the usual CG activity that wasn't too out of hand. No severe wx parameters met here. No hail and highest winds during the event only around 35mph.
5/26/2019 7:00 AM 1.39 M M M M While parts of El Reno was being ravaged by a tornado 25 miles to my southwest around the 2230 time frame, the same system came over us with nothing more than the rainfall logged and suprisingly..very little wind. What was interesting was the near continuous in cloud lightning; not many CG strokes. Thunder was nearly continous for about a half an hour during the event.
5/29/2019 7:00 AM 1.10 M M M M Late report due to power failure. we experienced the largest hail here since May 2010. tennis ball sized hail fell between 1802-1805. Mesocyclone went right over the farm and was accompanied by blinding rain (visibilties less than 100 feet); hail as described, wind gusts to around 60mph according to my wife. I was out chasing and downtown Piedmont missed the hail but had RFD winds of around 50mph.

6/7/2019 7:00 AM 1.73 M M M M Thunderstorms moved in around the 0800 timeframe, lasted until around noon, then some wrap around precip. from the upper level low responsible for the latest siege of unwelcome rain in the early evening.
6/10/2019 7:00 AM 2.02 M M M M Late entry.. marginally severe storm came thru commemcing around the 0800 period. What was interesting about this storm was a brief but intense period of positive, staccato CG's along and just ahead of the forward flank of the storm complex. Several bolts well within a mile of our house. Also of note was a core of quarter to near golfball sized hail just to our north with this cell, but none here at the house. Highest winds around 40mph. Thismorning, a refreshing breeze with temps. in the upper 50's.

8/27/2019 7:00 AM 2.71 M M M M Severe storm with prolific amounts of CG's with several within 1/4 mile of the house. Not sure if any hail fell as I was out stormchasing this beast. Wind gusts estimated around 65-70mph by my wife. Several branches down including part of tree planted a few years ago partially destroyed. One of the more notable storms we've had here that raged between 2000-2230 timeframe. Worst of it was during the first hour.
8/30/2019 7:00 AM T M M M M Strong storms to our north, west and east with IC lightning at time of observation.
