Monitoring & Reporting Snowfall


A winter storm moved through early this week with impacts from the storm felt from Monday through Thursday. Several feet of snow accumulated on Casper Mountain and in the Wind River Mountains with over a foot of snow again in Casper and the Lander Foothills.

The wintry storm also resulted in many locations breaking new daily record low maximum temperatures, and record low temperatures over the last few days.

Benefits to the Snow Pack:

This storm has done wonders for our snow pack. The long range models are indicating that another storm is possible early next week.

The amount of water contained in this snow is rocketing toward normal for this time of year.


So, what is going on? Casper gets several feet of snow yet the snow pack is still well below normal? Yup. Hard to believe but the amount of water contained in the snow pack is still well below normal and even below where it was last year! However, the amount of water in the lower elevations has worked to move Natrona and Fremont counties out of "Extreme" drought into "Severe" drought. Casper's climate site is reporting over an inch above normal, Lander has exceeded their normal snow amount by over a foot now so the low elevations are doing well. We just need the mountains to store up some water for the summer...

The above graph shows the snow water equivalent contained within the snowpack this year (in blue) compared to last year (green), both compared to normal (purple) on Casper Mountain. So, even though nearly seven FEET of snow has fallen in the past two weeks, there is still less water in that snow than there was at this time last year, and there is much less (about 5" of water) than normal.

The map above shows that Fremont and Natrona counties have improved from "Extreme" drought to "Severe" drought due to the recent snow storms. We still have a way to go to get us out of drought completely.
