Observation Date Observation Time Precipitation Snowfall Snowfall SWE Snow Depth Snow SWE Notes
10/1/2011 7:00 AM 0.00 0.0 M M M Hot day is predicted. This week the kids wear coats to school and come home to change into shorts and tank tops. No precip in sight. (or on site either)
10/2/2011 7:00 AM 0.00 0.0 M M M Extremely hot this weekend. I didn't know I could get a sunburn in October. No rain although the occasional passing clouds were pretty.
10/3/2011 7:00 AM 0.00 0.0 M M M Quite a hot afternoon - a bit breezy at time. Sunshine sunshine sunshine and no precip.
10/4/2011 7:00 AM 0.00 0.0 M M M Slightly cool wind with hot sun and still dry dry. But great soccer weather.
10/5/2011 7:00 AM 0.00 0.0 M M M Looking forward to some rain hopefully soon.
10/6/2011 7:00 AM 0.06 M M M M A nice light rain came through some time early this morning. What a nice refreshing morning!
10/7/2011 7:00 AM 0.24 M M M M Rain came last night with a brief sunrise and then overcast. Looks like the hot weather has turned. It looks like I won't be reaping more bugs than precipitation in the coming days.
10/8/2011 7:00 AM 0.24 M M M M Rained in the afternoon a small amount. Most of this rain must have come last night and early morning. Nice to have some rain.
10/9/2011 7:00 AM T M M M M Heavy dew and scattered low fog in the valley this morning.
10/10/2011 7:00 AM 0.01 M M M M Another morning of patchy valley fog. Unsure if the water was from a heavy dew or actual rain from clouds. Beautiful sunny day today and yesterday. The box elder tree is down to 2 leaves, but I still have a frost-touched tomato holding on and the cottonwoods have lost some leaves but most haven't turned colors yet.
10/11/2011 7:00 AM 0.00 0.0 M M M hmm enjoyed the moisture while it lasted. now time for fall gardening.
10/12/2011 7:00 AM 0.02 M M M M I was surprised to see so little in the rain gauge this morning. We came home between 10 and 10:30 p.m. and hit quite a downpour west of us towards Miles City, but it must not have made it all the way here. Breezy this morning and chilly.
10/13/2011 7:00 AM 0.00 0.0 M M M Cool and sunny.
10/14/2011 7:00 AM 0.00 0.0 M M M Nice cool but windy day.
10/15/2011 7:00 AM 0.00 0.0 M M M I expected rain this morning but awoke to clear skies which surprised me (later the clouds came).
10/16/2011 7:00 AM 0.06 M M M M Our expected rain let us play soccer all Sat. morning despite drizzle and driving conditions weren't affected. This morning's hard freeze did however mean that I now have taken out the inside of my gauge to preserve it. I had to wait for the rain to thaw to read it. I guess I should be getting my snowboard ready too.
10/17/2011 7:00 AM 0.02 M M M M Some rain came in the night. Otherwise Sunday was a lovely sunny day and followed by a cold night.
10/19/2011 7:00 AM 0.00 0.0 M M M Cool, breezy, and sunny day.
10/20/2011 7:00 AM 0.00 0.0 M M M Nice and warm day for working outside.
10/21/2011 7:00 AM 0.00 0.0 M M M Thursday was a nice and sunny day, with a very cool night. No precipitation.
10/22/2011 7:00 AM 0.00 0.0 M M M
10/23/2011 7:00 AM T M M M M I don't think I would have known it rained, but I was outside in it Saturday doing some work after dark. The day was sunny and the wind gusts were quite strong in the late afternoon, but settled down by sunset.
10/24/2011 7:00 AM 0.00 0.0 M M M A nice cool and sunny day. Most of the leaves have turned to yellow, yellow and green, or brown. Many of the cottonwood trees on the river are bare, but in our yard we are still raking. My rose bush seems to want some last blossoms. Fall is definitely progressing.
10/25/2011 7:00 AM 0.03 M M M M Rain started as sprinkles and went to a steady patter as we left a late dinner at our neighbor's to go home around 8 p.m. Apparently it didn't add up to much and the night sky was clear. Most of the calves in our area have been shipped and the cows are moved or moving to winter pastures. The grasshoppers ate much of the winter grass forage around here and neighboring places, as well as our home gardens.
11/6/2011 7:00 AM 0.12 2.1 M 2.0 M I didn't measure the water in the snow last night, but I think we lost some in this measurement to the ground melting as much as settling. Last night there was 5" and today 2". Still the gauge reading would have caught some of that, but I don't think it had a good catch with the wind we had.
11/7/2011 7:00 AM 0.00 0.0 M 1.0 M The snow is mostly melted, but not in my garden where I measure.
11/8/2011 7:00 AM 0.00 0.0 M M M There was a heavy frost this morning and I notice the Powder River is full of frazzle ice and is flowing slowly at the surface. Maybe it will freeze this week.
11/9/2011 7:00 AM 0.00 0.0 M M M Cool but sunny day!
11/13/2011 7:00 AM 0.00 0.0 M M M I thought with all the wind last night we were getting a snowstorm, but nothing is indicated this morning.
11/14/2011 7:00 AM T M M M M It rained last evening but nothing recordable apparent in the gauge this morning. Cool day - all the leaves are down.
11/15/2011 7:00 AM T 0.5 T 0.5 T Woke up to light snow. Really big flakes but not much moisture. I'm now remembering why I like summer better - rain is easier to measure.
11/16/2011 7:00 AM 0.00 0.0 M 0.0 M Yesterday's snow melted off by midmorning.
11/18/2011 7:00 AM 0.00 0.0 M 0.0 M Surprisingly nothing but a lot of cold wind and dreary looking clouds.
11/19/2011 7:00 AM T 0.5 T 0.5 T Intermittent patches of snow on the ground and still accumulating. Too cold for much.
11/20/2011 8:00 AM 0.07 M M M M
11/21/2011 7:00 AM 0.00 0.0 M 1.0 M Sunny and cold this morning. Beautiful clear afternoon yesterday which warmed up considerably from the morning, but didn't melt off the snow.
12/1/2011 7:00 AM 0.01 0.2 M M M Windy, Windy, cold. The snow started late here - and never amounted to much.
12/4/2011 7:00 AM T M M M M Windy, blowing, and a skiff of snow on the ground - enough to turn it white anyway.
1/22/2012 7:00 AM 0.02 0.0 0.00 M M 0.25 inch of frozen rain is coating everything. It began yesterday afternoon.
