12/5/2016 7:00 AM 0.07 1.0 M 1.0 M This snow came in with very little wind, the third time this fall. We almost never have snow come down with so little wind, so maybe this is a record for snow coming straight down.
12/6/2016 7:00 AM 0.19 4.5 M 4.5 M The accumulation of new snow was measured yesterday afternoon. The snow shrank about an inch during the night. This snow came down with a light wind out of the north, so the gauge probably is a little conservative on the total moisture.

12/9/2016 7:00 AM T T M 3.0 M The trace of snow was about 8:45 last night. It was very lightly snowing when I was walking the dog. It looked more like snow flakes than a light frost. The temperature was -7 with a very light drift to the air.

12/17/2016 7:00 AM 0.25 5.5 M 6.0 M This snow came in with a strong wind, 10-20 mph, so the gauge didn't catch all the snow. My guesstimates as to the snow amounts are only estimates. I checked on the tractor and hit a drift that was knee deep. With the temperature -37, I have not spent much time outside. I might edit the amounts of snow after I look at more measurements.

12/19/2016 7:00 AM 0.00 0.0 M 3.0 M Total snow ranges from drifts of a foot or so to almost bare ground. It is impossible for me to make an accurate guess as to the average, but it is a lot more than a trace, an less than the 5 inches I had yesterday. We have 30 plus mph winds which are really moving the snow around.

12/26/2016 7:00 AM 0.35 9.0 M 9.0 M This is the amount that was in the rain gauge. This storm came in with a strong northeast wind and finished with a strong southwest wind. I think that the gauge missed a good portion of the snow. All the snow amounts are guesses due to the various winds.
12/27/2016 7:00 AM 0.00 0.0 M M M There are drifts and bare ground, I cannot guess what the average total snow is.

12/30/2016 7:00 AM 0.00 0.0 M M M We have both bare ground and drifts. The average snow is more than a trace, and probably less than 6 inches. I cannot guess any more accurately.

1/4/2017 7:30 AM 0.03 0.5 M M M There is a complete cover of 2 inches of snow, and drifts that are much more. I don't know what the average is.
1/5/2017 7:00 AM 0.08 2.0 M M M The new snow is more of a guess than normal. The snow came in with out very much wind, so the gauge is probably pretty accurate. I still cannot guess the total snow average.
1/6/2017 7:00 AM 0.00 0.0 M M M We are getting some pretty nice drifts, but I cannot guess the average snow depth.
1/7/2017 7:00 AM 0.00 0.0 M M M Too bad we don't get to count snow that is moving horizontally; it would allow me to report moisture much more often. There is about an inch of snow in the wind blown areas and drifts. I have no idea what the average is.

1/9/2017 7:00 AM 0.00 0.0 M T M There could have been a trace last night, but I did not find any evidence of it. More than half the area is bare ground, with drifts wherever there is any protection from the wind. I think total snow is a trace, but it is a very snowy trace.

2/23/2017 7:00 AM 0.29 3.0 M 3.0 M The wind is really strong, with my wind gauge saying an average of 14 and gusts to 25 mph. I'm sure that the rain gauge did not catch more than half the snow. I would take a core sample, but I'm not sure what the average snow is. The wind is so strong that it has blown my favorite spot partly clear. We go from almost bare ground to drifts, with most of the snow going by.
2/24/2017 7:00 AM 0.12 2.0 M 4.0 M This snow came in with a strong wind. My guess is that the rain gauge caught about half the moisture. This wind was so strong that my normal place to measure snow was blown clear. The snow totals are pure guesses. I don't know where to take a care sample that would be meaningful.
2/25/2017 7:00 AM T T M 4.0 M Total snow is a guess. Everything is covered with snow, but the depth depends on it exposure to the east wind. The drifts are really dense snow. When I was feeding my cows this morning, I had to put the tractor in 4-wheel drive to get through about 6 inches of snow.
2/26/2017 7:00 AM 0.00 0.0 M 4.0 M Total snow is a guess. There is a couple of inches of snow everywhere, and drifts.
2/27/2017 7:00 AM 0.00 0.0 M 4.0 M Total snow is a guess. I originally guessed 3 inches. On 2/28/17 I measured the snow depth in the field south of the gauge, and it was 4 inches, so I changed the guess to 4 inches on 2/28/17.

3/5/2017 7:00 AM 0.00 0.0 M T M Over half the ground is now snow free. However, there is still a lot of snow in drifts wherever the snow is protected from wind and sun.
3/6/2017 7:00 AM 0.13 0.1 M T M Virtually all of the moisture came down as rain. We had a thunderstorm about 10:30 last night, I don't know if all the rain came with that thunderstorm or if we had more showers overnight.
3/7/2017 7:00 AM 0.08 1.5 M 0.5 M Total snow is a guess. The ground is completely covered, but it isn't very much.

3/9/2017 7:00 AM 0.00 0.0 M T M It is impressive how much snow has melted over the last 2 days. I think most of it went into the ground. There was very little runoff, but there was probably some evaporation.

4/26/2017 7:00 AM 0.27 2.0 M 1.0 M This snow came in with a strong wind, so the gauge probably did not catch all the moisture. The snow was melting almost as fast as it came down, so the snow amounts need to be taken with a grain of salt.

4/28/2017 7:00 AM 0.75 2.0 M 2.0 M This is an accurate measurement. About 0.60 inches of this moisture came straight down. The last 0.15 came down with a 5-10 mph north wind. The snow totals should be taken with a grain of salt. The snow is only on grassy areas and vehicles, the driveway is just muddy. Most of the snow is melting as soon as it hits.
4/29/2017 7:00 AM 0.21 3.0 M 3.5 M This is the wettest April in the 9 years I have been reporting to COCORAHS. I measured the snow all over, and found that the depth of the snow depended on the height of the grass. 2.5 and 3 inches were the most common measurements, but there were far more 4 thru 7 inch depths than below 2.5. Therefore, my guess as to the average is 3.5 inches. The new snow is a guess. Most of the snow melted about as fast as it come down until the temperature dropped after sundown. The snow came in with a strong wind, 24 mph was the highest I saw, so the gauge probably did not catch all the moisture.

5/19/2017 7:00 AM 0.80 3.0 M 3.0 M The rain and melted snow is an exact measurement of what was in the gauge. A large portion of yesterday had winds up to 20 mph, so the gauge is probably under reports what actually fell. The snow was melting as it came down, so new snow is just the most I measured, and not accurate. The total snow is the approximate average of many measurements, and is probably representative of what it is at 7:00 AM.

4/27/2017 10:30 AM I was over a mile away, closer to WY-NT-4, when this happened. I am relying on my wife's description which was the same as I experienced where I was. The hail did not completely cover the ground. The time of starting is approximate because neither one of us looked at a clock when the hail started.

6/5/2017 6:01 PM There were several hail storms over the course of about an hour. Sometimes there was just a little hail with the rain, and other times there was mostly hail with a little rain. The length of time it was hailing is a guess because it was so intermittent. NA 1/4" Pea Size NA Hard|White Ice 15 10min no damage Intermittent True After rain After smaller hail
