As far as the current conditions for your Tuesday night across east Tennessee, they seem to be relatively clear. Temperatures are currently sitting in the mid 40's with the low for most of the area bottoming out in the mid 30's. For the morning commute to school and work bundle up! Temperatures will be in the low to mid 30's with winds blowing around 10+ mph. Be on the look out for wind advisories issued by the National Weather Service as there are some already put out for Seviere, Blount, Cocke counties and counties near the Smoky Mountain Region. This means winds between 15-25 mph with gusts up to 40 mph. For your Thursday, temperatures will be a little colder with high's in the mid 30's. Thursday should be mostly sunny and clear. To finish our the work week, Friday is expected to remain clear and sunny with highs in the low to mid 40's.
Diving right into it.... this is of the upper level winds in the atmosphere over the next few days. We can see at the beginning of the gif a dark red pattern across northern Kentucky. This is the front bringing in that cold polar air from our northwest along with the winds. Over the next few days (Thursday into this weekend), this cold air will be sticking around and bringing a possibility of some snow flakes into the east Tennessee area.

So what does this weekend's snow chances look like? Well... Many models indicate snow on the leading edge of the system. With cold air in place from the front coming through today, and the system impacting our area during the coldest time of the day (early Saturday morning) snow is likely. Sadly for the snow enthusiasts though, this will be quickly washed away with lots of rain behind it. Snow amounts of up to half an inch are possible for most of the east Tennessee valley. As the day Saturday picks up, warmer air and moisture from the system (Warm air advection) will take-fold and make the transition from snow to rain. Rain will be the brunt of this systems as we are expected to receive amounts of near half an inch. Overall, messy roads caused by ice and snow should not be a cause of trouble as high's Saturday are expected to be in the low to mid 40's and low's for Saturday night being in the mid 30's. Since temperatures are not expected to reach or dip below the freezing point, the chances of ice are very low for most of east Tennessee. For your Sunday into the early part of next week, the system will move out leaving mostly sunny skies and high's in the mid to upper 40's.
