(The latest day being on 4/16/1999) Periods of light snow and flurries last evening starting around 7:30pm with intermittent very light snow thru the night. Ob. time right at 7am, a light rain/snow mix! Temp. around 37F.
4/21/2020 4:00 PM 0.18 M M M M Late report: For yesterday 4/20.. moderate thundershower with a burst of pea to marble sized hail early in the evening, another weak supercell thunderstorm skirted us around the 1930CDT timeframe with wind gusts to around 35mph from the NW.
4/22/2020 7:00 AM 0.20 M M M M Experienced the northern edge of the precip. shield of the convective complex to our south. Occasional IC and CG activity was the chief event here during the 2100-2230CDT timeframe. Thismorning at ob. time 0900, convective complex just to our north produced an outflow boundary that is teasing my location.
4/23/2020 4:30 PM 0.47 M M M M Another late ob. but better late then never. All rainfall measured was from late yesterday afternoon. No rain since then.

5/8/2020 7:00 AM 0.45 M M M M Thunderstorms last evening ended up being more bark than bite. Moderate amount of lightning, no hail. Max. winds around 30mph. Refreshingly brisk thismorning with fresh northerlies ushering in our last formidable cold front of the season.

6/20/2020 7:00 AM 1.55 M M M M This was the most rain logged in a single day since 8/27/19, and the first measurable rain since 6/3. Most of the rain occurred in the mid/late AM hours; 1.25 between 9-12pm, then a gentle, soaking rain thereafter. Moderate amounts of thunder at times. Mesolow induced winds early in the evening (between 1845-2000 CDT) with gusts to approximately 40, maybe 45mph.
6/21/2020 7:00 AM 1.38 M M M M Rainfall measured came exclusively from a surprise severe thunderstorm that rolled thru from around 0530-0630. Hail and wind barely met severe criteria. Lots of quarter sized hail, a few stones maybe close to half dollar that lasted around 10 minutes (roughly 0540-0550 timeframe) Highest winds at leading edge of gust front, estimated between 50-60mph and lasted until the hail started, then slowly abated. Lightning was mostly in cloud but a fair amount of it. One of the most notable storms of the whole year thus far.

7/11/2020 7:00 AM 1.70 M M M M Rain Pour excessively and for about 10 plus minutes the rain was horzonal.
7/12/2020 7:00 AM 0.33 M M M M This observation is based on what my wife measured as I am out of town. Apparently it was the most intense storm of the year. Close to the 11pm-midnight time (estimated).. aproximately 70-80mph wind gusts and numerous very close CG's. Rainfall measured may be an estimate as rain was horizontal due to intense winds. Some tree damage in the area and power outages. Wish I would have seen this in person.

9/1/2020 7:00 AM 1.73 M M M M An eventful day to wrap up an otherwise drier than normal, mundane month of August. One well developed funnel cloud and one landspout spotted around 8 miles north of the farm around 1720-1730CDT. Waves of moderate to heavy rain occasionally accompanied by intense lightning lasted thru the evening. One brief period of near severe criteria wind gusts occurred between 1745-1800, according to the Mrs. Storms with intense lightning were worse just off to my south towards OKC and Yukon during mid and late evening. Rain moved out after about 1am.
9/3/2020 7:00 AM 1.50 M M M M Another bout of heavy rain between 1730-1900. Moderate amounts of lightning but nothing too noteworthy. What was noteworthy was the brilliant rainbow afterwards. One of the best I've ever seen.
