Winter Storm Update: Tuesday Morning Data

The new Tuesday morning run of the GFS is in. I'm quickly digesting some of the data for the southeast Missouri, southern Illinois, western Kentucky, northwest Tennessee, and northeast Arkansas area.

It still looks like it is going to be a primarily ALL SNOW event for the area. There are a few exceptions to that in northeast Arkansas and western Tennessee.

Here is a view at the data for Cape Girardeau, Missouri:


Other points of snowfall amounts:

• Cape Girardeau, Missouri: 8.8"
• Farmington, Missouri: 7.3"
• Jonesboro, Arkansas: 8.9"
• Paducah, Kentucky: 9.4"
• St. Louis, Missouri: 0.4"

I have had several people asking about other points in the Missouri bootheel and southern Illinois. Unfortunately, NOAA only provides data points for this type of data for specific locations in the area. There aren't any locations in either the bootheel or in southern Illinois. Of course on air we will be giving forecasts for the entire area.

With this storm the track means everything. There will be a very sharp cut-off of snow on the north side of the storm. A deviation of the storm track of 25-30 miles could mean the difference in getting 0" instead of 6" of snow.

The above numbers are not our forecast. These are just numbers from a computer model.
