The first big winter storm of the year got its start in the lower Mississippi Valley before charging northeast to New England. The Eastern Seaboard is getting attention for the snow they are seeing, but they caught a little bit in southern Illinois as well.
At 1054PM, CT, Decatur was reporting a temperature of 24 degrees with clear skies and haze. The recently fallen snow and clear skies were leading to the radiation fog developing across the region overnight. Fog was prevalent throughout east central Illinois, where temperatures were slightly depressed thanks to the recently departed system, which was now centered over Cincinnati, with clouds terminating at the Indiana-Illinois state line.
The upper level pattern is quite active, so this period of tranquility around Decatur is going to be short-lived. A bit warmer weather is coming tomorrow with a weak ridge between the system that clobbered the region today and a Clipper moving through the Upper Midwest, scheduled to arrive in central Illinois on Saturday afternoon. Snowfall is going to be significantly lighter than the snow of the last 24 hours, but it will be persistent, and linger through the rest of the day Saturday.

Well, this is interesting. I know Clippers, especially when they arrive with warmer temperatures, aren’t always a sure thing, but I’m surprised snow is being left out by so many outlets. Here is a look at the satellite, with the monster area of low pressure that brought snow earlier, looking like a hurricane over the Ohio Valley.
