Before 8 AM, warm, humid air was streaming in from the south, with a cold front pushing rain toward us.
Winds will pick up (13 MPH or so), then that rain will be here this afternoon.
The HRRR model thinks a main “line” of rain, briefly heavy, will show up between noon and 1:30 PM or so, followed by maybe another light passing shower before dark.
Into tonight, you may want a light jacket for any outdoor sporting events as temps will fall into the upper-60s by 7 PM and the mid-60s by 9 PM.
Like this morning, patchy fog is possible overnight tonight into early tomorrow morning.
NOTE: Barring a partly/mostly clear nighttime, fog could develop and be around for tomorrow’s morning commute.
GFS Model Loop through Sunday Morning
We will remain dry through Saturday as high pressure continues to hold in place through then. Flow will become southerly on Saturday, so expect temperatures about 10-12 degrees warmer than they are today (middle 80s).
Temperatures will remain near normal into tomorrow. Unfortunately, these cooler temps won’t last that long.

Just like that, temps will jump back into the 80s on Friday and stay in the 80s through the weekend. Sunny skies look to hang around through at least the first half of the weekend, with no measurable rainfall in the forecast through Saturday.
Regional Radar 11:30AM CDT
Rain has encompassed much of Middle Tennessee this morning and another heavier batch is moving in from the west for the lunch hour. Plus or minus a few more showers after this next rain swath, we will be largely done with measurable precipitation by late afternoon/evening. The HRRR is in good agreement with this scenario.
Some fast moving showers have popped up over Middle Tennessee this morning, in addition to extra cloud cover. A gradual increase in rain coverage is expected today as moisture pumping in from the Gulf of Mexico and Hurricane Nate aid in shower development. Additionally, a frontal boundary will spark off a few storms after dark tonight.
