The temperatures think today is opposite day. Instead of warming through the day, temps will be cooling through the day. Why? A cold front passed through during the morning hours.
Drizzle is already showing up on the radar in west Tennessee, moving closer. However, air is super dry aloft, so it’ll take time for rain to hit the ground. Therefore, for most of the afternoon Williamson and Davidson Counties will be rainless and overcast.
It is a very pleasant and mild afternoon out there today without temperatures topping out in the low 60’s. These conditions will not last however, as an approaching cold front will bring temperatures back to near normal for this time of the year, along with renewed chances for rain. I have a map below which shows the location of our cold front marked with the blue triangles as of 12 PM Central Standard time. Out ahead of this front, we are in a warm sector with a mild and breezy southwesterly flow. As this front approaches and moves through tonight we will see a drop in temperatures and even a slight chance of a shower.
The month of February has been a wet one so far, with rainfall values well above average. The Nashville Weather Service has recorded a value of 6.18 inches of rainfall for the month already, and it’s only the 13th! This is four and a half inches above the normal for this month. The good news is we are seeing a few dry days ahead before the next round of rain returns. Today, we will see a sunny, dry day with temperatures rising into the low 50’s.
A Flood Watch continues for Davidson County until noon today. We’ve had quite a bit of heavy rainfall this morning, but not as much as the models thought. Totals should settle in around 1.25″ or so; models predicted 1.5″ to 2″. Although some area creeks, streams, and rivers rose to action stage, none are expected to rise to minor flood stage, which is a relief.
Flood Watch: A Flood Watch remains in effect for Davidson County through midday Tuesday.

Yesterday, Mayor Briley allocated money to modernize the sirens. A big step forward well celebrated on Twitter because previously, modernization had support but no money.
If you stepped outside early this morning, this may have been your reaction:
Old Man Winter is back. We are only going to reach a high of 37º this afternoon with plenty of sun. A north-northwest wind around 10 mph is making it feel sub-freezing.
A flash flood watch is in effect from 3 PM through late evening for Davidson County. Williamson is excluded from this watch.
From NWS Nashville:
Up to 1 inch of additional rainfall will fall in areas that already have saturated ground conditions from yesterday`s heavy rainfall. Street flooding will be a big hazard for travelers. Low lying areas and poor drainage areas will be at risk for flash flooding. Also watch for flooding along small streams.A wind advisory is in effect from 10 AM until 7 PM tonight for both counties. As a cold front approaches today, we’ll have sustained winds 20 to 30 mph with gusts up to around 40 mph. After rainfall begins, winds will begin to decrease.
