Eyes Watching Snow

A spoke of energy is spinning around an area of low pressure that is currently centered over south central Kentucky.

Just ahead and along the spoke precipitation should begin to pick up in intensity.

The Storm Prediction Center has also taken notice of the current environment. They have recently issued a Mesoscale Discussion for western Tennessee, southeast Missouri and northeast Arkansas concerning snow rates picking up.

Laura Wibbenmeyer, former co-worker of mine at KFVS-TV, is in Portageville, Missouri and is reporting that it is all falling as snow. Nothing is sticking to the roads but snow is covering grass and car roofs.

The National Weather Service in Memphis is going a little higher than me with snow totals. They have mentioned that the freezing level has dropped further and is approximately 800-1,000 feet above the surface. If that is the case, more snow is likely to fall. Unfortunately, I don't have access to all the hi-res temperature profile data right now. (That is all located on my laptop at home.) However, I still think the snow will only accumulate on grassy and elevated surfaces.

Interesting to note the the NWS in Memphis has noticed that the rain is changing over to snow once the surface air temperature hits 36°-37°.
