WBBJ 7 Forecast Update:
Well this forecast is shaping up to be a doozy unfortunately. There are a lot ingredients in this winter brew and a lot of possible scenarios that could play out. First off, there is a chance the low tracks too far south to bring much of anything to West Tennessee. There is also a chance the dry air from the north cuts off the low and keeps most of the precipitation south of I-40. There is a chance we are a couple degrees to warm for snow anyway and just get a cold rain. But there is also a scenario, where the low tracks through south West Tennessee, the moisture beats the dry air and we are down around 31-33° when the showers fall and we get snow. Still the best chances for snow we believe is just north of I-40 with up to an inch being possible but more likely just a dusting to a 1/2″ (if things work out for snow to fall). I would NOT be shocked in the slightest if we get a repeat of Monday either and just get a cold rain. Another thing we know for sure, there will be less showers coming down on Thursday than we saw on Monday.
A cold front will pass by early Thursday morning and will stall out during the day. A low pressure system will come up through the southern plains and pass just south of us late in the day. That will usher in showers by the afternoon. Some of the showers will try to transition to a brief wintry mix or possibly some light snow late in the evening. Snow chances are greater the further north you are, but precipitation chances are lower the further north you are as well. Also, the longer the showers hang around during the day, especially if they do after the sun sets, that will create our best chances for some small snow accumulations. This is another system where being off in the forecast by 1-2° could make a huge difference in what you see in your area. Catch the latest coming up here.
