HRRR for 6:00 am Wednesday. Not hard to see the cold front. Temps will fall fast from the mid 60s to the low 40s once it passes during the morning hours.

The brutal cold is the big story. More on that in just a bit. First, quick note about the snow.
Light snow showers across the area have been stubborn to dissipate today with some sites still reporting light snow or flurries ongoing this afternoon. So a dusting or a quick half inch of snow isn`t out of the question still through this afternoon, but all of this should wind down within the next few hours. NWS NashvilleIf you get a quick burst of snow, roads can deteriorate quickly on a local level, even if just for a few minutes. Take it easy out there.
Forecast rain amounts have increased in the last 24 hours, with widespread 2-3 inch rainfall expected between Friday evening and Sunday evening.
Now that the leaves have fallen, this is a good time to check the drainage on your property and clear out any gutters/drains/culverts/ditches that are designed to carry water away. While the flood threat is low, clogged drains could create an issue.
Record highs in Nashville for Monday, Tuesday and Wednesday are 79°, 80° and 83°, according to the National Weather Service. If we don’t tie or break those records this week, we’ll be awfully close. We’ll cool off behind a cold front for the weekend, but still not seeing any freezing temps in the long range computer models.
