Our Cocorahs sample site on a north-south ridge top at 8750 feet elevation has entered the snow-neutral drift regime. While the weather stays cold and dry, the snow depth will stay about 4 inches. New snow will come from the west and build up east of our ridge.

Heavy runoff requires repair of the ditch on the switchback below our house. Significant damage to broad leafed plants including broccoli and lettuce in the garden

Wind was what I thought at the time was "brisk" and which I now estimate was 25 mph. The heavy rain and hail was preceded by light intermittent rain before and more extended intemittent rain. My observations were cursory because Marith and I ended a hard job of logging in our forest just before the hardest rain and darkness overtook us as we were recovering in the hot tub.

5/7/2014 2:16 PM The pad has been in place since the day you asked us to put out hail pads on 4/12/2014. The pad has undergone several snow storms since then. The rice sized hail happened sometime in late April, possibly 4/19 or 4/20 when I was not present. Hail pad left out. First observed hail on 5/7/2014, recorded here as pea sized, but hail strikes observed on pad are negligible and I am leaving hail pad out so as not to waste the pad. I shall send today's pad in along with the last wimpy pad from the 2013 season when the snow season ends and we finally get hail worth recording with a pad. There was a few nearby lightning strikes with this mini storm, and there are more clouds to the west. The storm area and density increased about 5PM and hail fell again between 5:27PM and 5:30PM. Storm cloud extends from the northern horizon to the southern horizon, east to Guy Gulch and west to the north fork of Clear Creek. Lightning storms are widespread. At 5:44 PM I am terminating this hail report and switching to a significant weather event. 90% of hail strikes occurred on 5/7/14. Hail did not accumulate on ground because it fell over 195 minutes, giving plenty of time to melt. 3/8" Rice Rice Soft|White Ice 195 10min no damage Intermittent True After rain After smaller hail vertical 200 .125
1/1/0001 12:00 AM This is the hail pad that I put out on 5/08.14. I reported about 200 rice sized hail strikes on 5.8.14. Because I was afraid I would run out of hail pads, so I left the same pad out so I could record more over the weekend. I did not observe more hail strikes on the pad until 6:00 AM on 5/12. I took the frozen pad into the house at 6:00 AM and let it thaw, and immediately saw that a lot more hail must have fallen sometime during the night. In addition to some of the rice sized strikes left on 5/7, I saw about 100 strikes of 3/8 inch size and somewhat fewer of 1/4 inch size. I estimate that a total of 80 hail strikes occurred in the evening of 5/11 or the morning of 5/12 I am reporting those in the details printed above. It is likely that the hail fell in the evening of 5/11 because 12 inches of precip occurred in the form of wet snow during the night. If this snow had fallen late in the storm, the hail strikes would not have been as well defined as those that pummeled the hail pad. 3/8" 3/8" 1/4" Pea Size Hard no damage False 84 .58
5/21/2014 3:44 PM Storm began with a short, heavy rain. I didn't get the hail pad deployed until the hail ended. It was an insignificant hail storm. Sun came out about 3:48 PM. Much more hail continued overnight. Pad taken in 5/22. Hail melted, depth not available. 3/8" 1/4" Pea Size Rice Hard|Soft|Mixed|White Ice 20 10min no damage Intermittent True After rain After smaller hail 2000 .2

1/1/0001 12:00 AM I was out of town from noon 7/14 until 7/16 early evening. I observed no hail at our location, but reached my destination in South Park just after a heavy hail storm passed in the afternoon. I shall assume that the hail at our house occurred on 7/16 because that was the date of the heaviest precipitation at the stations nearest us. I entered a multi-day accumulation report of .61 inches for the 3 day period that we were gone. 1/4" Pea Size Rice Rice False 144

8/27/2014 6:02 PM (Complete report deferred until tomorrow morning because it is getting dark. There will probably be damage in the garden.) Added 7:58 AM, 8/28/2014. Originally I reported that the dominant hail was 3/8 in diameter and that there was no rice sized hail. I learned this morning when I collected the hail pad that the numerically dominant hail was rice sized and the greatest volume of hail must have been pea sized. These results were confirmed by Marith, my wife this morning, who had taken shelter in the barn where she could both hear and see the hail storm. I checked the garden this morning and there was no damage. 3/8" 1/4" Pea Size Rice Hard|White Ice 28 1min Intermittent True Same time as rain After smaller hail 10-20 .2 .5
8/31/2014 4:05 PM Hail was very soft. Could be called graupel. It stayed intact when hitting grass or soft dirt, but splattered when it hit a hard surface. A lot of hail fell in 4 minutes and covered the ground. 0.18 inches of moisture accumulated in the rain guage during 5 minutes of hail and the rain that followed. 1/2" Grape 3/8" 1/4" Pea Size Soft|White Ice 4 1min no damage Continuous True Before rain Same time as smaller hail 10-20 288 .25 .5
1/1/0001 12:00 AM I discovered that my hail pad, put out on 8/31, had rice sized hail that I failed to notice when I checked my rain gauge previously. It must have been when a trace of rain was observed on 8/12. I am recording it on 9/14. No hail pad was submitted for economy. RETIRED PAD after snow fall on 10/2/2014. Unchanged since 9/14.
