Special Weather Statement
Statement as of 5:07 AM CST on December 01, 2009
... First accumulating snow of the season appears likely over parts of eastern and central Missouri and southwest Illinois for Wednesday afternoon and night...
The latest weather data continues to indicate the potential of accumulating snow across the area for Wednesday afternoon and evening. The most favored region at this time appears to be from the St Louis Metro area south to around Farmington and east to near Salem Illinois... however all areas in eastern and central Missouri and southern Illinois appear likely to get at least a little snow accumulation.
Precipitation is expected to begin as light rain Wednesday morning over much of the area before gradually increasing in intensity heading into Wednesday afternoon. Colder air spilling into the region from the northwest will help change the rain over to snow over many areas in Missouri during Wednesday afternoon and early Wednesday evening in Illinois.
By late Wednesday night... some areas may have picked up a total of an inch or two of snow accumulation before the snow tapers off to flurries.
It must be stressed that there is still some uncertainty with regards to this storm... especially with respect to how quickly the cold air will build in to change the precipitation over to snow and also with the exact track of the storm. Any change to these two items could drastically impact the expected snowfall amounts.
Stay tuned to NOAA Weather Radio or your local media for further details or updates on this developing winter storm.
