Difficult Travel Christmas and Wednesday


A powerful winter storm system will be affecting much of the country from Christmas Day through Wednesday with widespread rain and a swath of snow. If you’re traveling by car back to the Tennessee Valley from areas West, North or Northeast mid-week, you’ll need to pay close attention to weather conditions. Here are our latest thoughts based on new model guidance.

The upper-level system will mature over the Southern Plains on Tuesday, forming an area ofsurface low pressure, which will serve to produce snow to its north and west The system will move slowly at first while it is still digging south but will quickly accelerate at it lifts northeast.


The highest chances for snow will stretch from Oklahoma through Arkansas and Western Tennessee and through the Eastern Great Lakes. Some areas in Arkansas through the Great Lakes may see nearly a foot, but very windy conditions will make even moderate snow a travel hazard by reducing visibilities.

As far as the Tennessee Valley, it looks like we’ll be in a position with respect to the low to see widespread rain on Christmas Day, but most of the heavy precipitation should be moving out as the colder air moves in Tuesday night. Some rain may turn over to snow during the first half of Wednesday, but no significant accumulations are expected at this time.

Remember, snow forecasts depend on discerning very subtle details, and small changes in those details can create big changes to the forecast. Check back here at ValleyWX.com for the latest updates.
