Storm Update: Heavy Snow & Bitter Cold

There was very little change in the models last night, and everything looks as it should on the radar, satellite and weather maps. A front has developed just to our south, with low pressure moving up through the Tennessee Valley. Another area of low pressure is just starting to show up off the coast of the Carolinas as well.I have updated my SnowMap in an attempt to narrow the ranges a bit and nail down, within a couple inches, what everyone should expect. The biggest question is: how much snow will about half an inch of liquid make? Normally, this sort of storm would be a 4-6″ event, but snow ratios will be double, or more, than normal.There is mostly light and moderate snow around the region this morning, but by afternoon, moderate to heavy snow should overspread the area. In addition to the increase in snow rate, the winds should start to increase. By late afternoon, temperatures will be down into the single digits as well.This will all lead to a dangerous travel situation this afternoon through early Friday. Blowing snow will make keeping roads clear problematic while greatly reducing visibilities. Bitter cold temperatures will reduce the impact of rock salt and combine with the wind to create dangerous windchills as low as -30º overnight. If you do not have to go out, stay put and stay warm.If you do have to travel, you are advised to allow plenty of extra time and to take an kit of emergency supplies, including LOTS of WARM blankets, Warm clothing, hats and gloves, High energy food (granola bars, etc.), Water, Batteries & a Flashlight, and a fully charged cell phone.
