Winter Arrives Again

Good afternoon and I hope you are staying dry. It has been a wet one much of the day and will continue to be as we work into this afternoon. Looking across the nation right now, a very clear cold air mass is working through, dropping temps to the west into the 20 and 30's. Working into tonight, expect low's in the mid to upper 20's and high's Wednesday in the low to mid 40's. 

Looking at the surface map right now, the cold front continues to work through dropping those temperatures through today and overnight. A transition is beginning to take place into parts of middle TN and will work in by this afternoon and evening here in the valley. This system is expected to move out overnight leaving chilly temperatures Wednesday but sunny skies by the afternoon. 

Looking at model guidance and comparing it to the latest radar scan, mixing is taking place just west of Cookeville right now. As temperatures continue to fall, rain will change to frozen matter this afternoon and evening. As model guidance is suggesting, a quick moving system will allow for limited accumulation tonight and clearer skies for tomorrow. 

Looking at the overall totals, we will stick with our original forecast from yesterday with a few tenths of an inch. Locally higher amounts are possible working into the northern valley, but with warm surface temperatures (50's today and 60's yesterday) snowfall will be limited. Expect any accumulation to be on grassy surfaces, leaving clear road ways into Wednesday (YAY). Even though we are not anticipating travel issues, be weary of slick spots with low's dropping into the mid/upper 20's overnight. 

That concludes today's forecast but stay up to date via Twitter & Facebook for any changes in the forecast through today. Have a good one and don't forget the jacket tomorrow!
