KNOXVILLE (WATE) - Get ready for some big changes Thursday, as temperatures will tumble through the afternoon and evening.
Most will start out the day in the upper 30s-lower 40s and end up near or below freezing by sunset.
Rain will be likely Thursday for most areas, as we start out. There will be a transition of rain to snow across the region as we go through the day, from west to east.
This system is moving rather quickly, meaning the bulk of the moisture moves out before the significantly colder air funnels in, which will help reduce the opportunity for significant snow totals.
The changeover to snow will start early afternoon along the Plateau and mid to late afternoon across the valley into the mountains.
It appears as though the plateau and southeast Kentucky will see around 1" or less, in most areas. The valley looks will likely see some trace amounts of snow, up to 1/2" and the mountains could see 3" to 6"+, especially above 2,500ft.
The bigger story may be the wind chill values overnight Thursday into Friday morning, which could bottom out in the single digits to below zero. The colder air lingers into Friday afternoon, as most will not get above 30°. Some sunshine and a light southerly wind should get us closer to 40° by Saturday.
Another similar storm system looks poised to barrel through late Sunday into Monday, with another rain to snow possibility, but the bigger story with this system will be the colder air.
It appears as though we could see single digit or even below zero temperatures by next Tuesday morning.
