Locally Heavy Snow and Rain In A Few Spots

A few locations will see heavy snowfall today, including the northern California mountains and Sierra and across the northern Rockies into eastern Montana. Meanwhile, locally heavy to excessive rainfall is possible across southern Tennessee into northern Alabama and Georgia. A more organized and widespread heavy rainfall threat may be possible midweek for the Ohio and Tennessee Valleys. Read More >

Winter Storm Summary Banner

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).

Large snowflakes started falling at the NWS Riverton office up at Griffey Hill by late morning. Snow fell off and on through the day with periods of melting in between.

Things started to come together by the afternoon. The infrared satellite imagery was impressive once all of the dynamic forcing aloft worked together!

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.

Blue Shades = Cool Cloud Tops

Pink Shades - Very Cold Cloud Tops

Dashed Yellow Lines = 500MB Heights (helps to identify where the upper level low was centered)
