Summary | Snowfall Totals | Reporting Snowfall | Safety
A very wet and dynamic storm system moved through the area on Tax Day, April 15th and it is taking its time to move completely out of the area. However, most of the accumulating snow is done with. Given the storm's Pacific origins, it was rather warm and wet, typical for this time of year but it was a challenge to nail down exactly where and when the snow would accumulate as the surface temperatures hovered around the freezing mark. As such, the amount of liquid precipitation that fell was healthy across the board while snow accumulation was highly dependent on surface temperature and elevation (Click here to see a pop-up video of a drive through Sink's Canyon to Lander on 4/15/15).

Click to Enlarge The Infrared Satellite loop above shows the rapid strengthening of the upper low as it spun to our south. We were in the strongly forced northeast quadrant of the system - watch as the pink area expands in the afternoon right over central Wyoming! Later on in the loop, you can see thunderstorms develop in southeast Wyoming.
