Early this afternoon there were a few snow flurries and by 3pm it was sunny warm and beautiful! The morning's precipitation barely wetted the ground.

5/6/2010 4:00 PM 0.50 0.0 M 0.0 0.00 At 6am there was a light dusting of snow. The very light snowfall has continued thru the day.

Start Date End Date & Time Duration in Days Precipitation Snow Depth Snow Depth SWE Notes
2/3/2010 2/04/2010 4:30 PM 2 M 8.0 M Yesterday(2/03/2010) temperatures reached 39 degrees in Roundup Montana and the snow in my backyard was measured at 6.25 inches. It was very cold last night and began snowing at around 8:00am today. I measured the total snow at 7.75 inches at 4:30pm today. The dirt roads had frozen over and with the additional snow on top, they are incredibly slick to drive on.
2/10/2010 2/11/2010 12:00 AM 2 0.00 8.3 M It was sunny and a little warmer today and yesterday than it has been...perhaps in the high 20s or low 30s (I don't have an outside thermometer so check the temperatures posted in downtown Roundup, MT when I am in town.
2/21/2010 2/22/2010 4:30 PM 2 1.00 7.0 M We have had daily flurries and it has been cold. I measured yesterday afternoon at 4:30pm and it was 5.75" of snow. Today it was showing 7.0". It did not seem that the flurries we have been having should have amounted to much of anything, so am thinking I must have measured in a slightly deeper area today even though I measure in the same basic area.
2/28/2010 3/01/2010 4:30 PM 2 0.00 1.5 M The weather has been warm the past few days (high 40s and mid-50s today). There are only patches of snow left. The place in my backyard where I measure still has a patch of snow.
3/7/2010 3/08/2010 12:00 AM 2 0.00 0.0 M There are still small patches of snow around my property in the areas covered by trees especially on hillsides but the area where I take measurements is finally snow free! The temperatures have been in the high 50's. It is nice to have a few spring like days before the next weather event happens!
3/16/2010 3/22/2010 4:30 PM 7 0.00 0.0 M Friday March 19, 2010 it snowed in the morning, just enough to "dust" the ground but it had totally disappeared by early afternoon. Today, March 22 it has "spritzed" (not even a real sprinkle) a couple of times but not even enough water to wet the ground!
3/24/2010 3/29/2010 3:30 PM 6 0.00 0.0 0.00 It sprinkled off and on Friday Match 26. I just received a rain gauge and do not have it up yet; however, the dampness on the ground was truly negligible. It is quite windy today so obviously a new front is moving in.
3/31/2010 4/01/2010 2:00 PM 2 0.00 0.0 0.00 It has been overcast and cooler but no precipitation.
4/4/2010 4/05/2010 1:30 PM 2 0.00 0.0 0.00 Very LIGHT occasional sprinkles on Saturday here at home in Roundup, MT
4/7/2010 4/12/2010 4:00 PM 6 0.00 0.0 0.00 It is cold in Roundup, Mt today (around 37F). It feels like their might be some precipitation coming our way.....think I just felt a few drops of "wet"!.
4/13/2010 4/14/2010 3:30 PM 2 0.00 0.0 0.00 A little weather front moved through Roundup, MT Monday night. The thunder must have been right overhead as it shook my entire house! There was a "light frosting" of snow in the morning and probably rained less than 1/4 inch throughout the day and has been dry ever since.
5/1/2010 5/05/2010 7:30 AM 5 0.50 0.0 0.00 It has been exceedingly windy the last few days, especially yesterday (Tuesday May 4). I heard reports of shingles being blown off roofs and entire roofs being blown off some out-buildings. There were snow flurries last night around 8pm.
6/16/2010 6/21/2010 12:00 AM 6 2.00 M M Until today, it had been raining off and on. Am estimating the total rainfall to be around 2 inches. We have had quite a bit of thunder and lightening. Friday night, one thunder bolt appeared to be directly overhead and actually knocked some papers to the floor, it was so loud and vibrated so hard. We were fortunate yesterday (when the tornado hit Billings) to experience only some thunder, a little lightening and some rain - there was hardly any wind with this particula storm.
