Merry Christmas! Some in Will Co got a White Christmas!
In this edition:
Sleet streaked through Williamson County this morning, but is long gone. Uneventful weather will follow today and tomorrow.
We may even see the sun. Satellite through 11 AM:
A few light, mid-morning Christmas showers are possible.
So says the HRRR model:
NAM3 model agrees:
These won’t be a problem, just a nuisance. You’ll have plenty of time to be outside tomorrow.
A rain system is approaching from the west. It should fall apart completely when it arrives tomorrow. Just clouds for us, so says the HRRR model:
But the NAM3 model thinks enough rain will survive. If this model is right, Christmas Day will be light, drizzly, and off-and-on.
Tonight, winds turn north. Wind chills will approach freezing.
Temps should drop below freezing shortly after 3 AM and stay below freezing until 8 AM or so. Early morning patchy fog may lay down a thin layer of ice on roads where fog settles. If you’re up early Monday morning and see fog on the road, assume a thin layer of ice has formed. Any such hazard will end about an hour or two after sunrise when temps rise above freezing.
Off and on rain will continue this morning into early afternoon. HRRR model (below) thinks rain will be gone by 3 PM:
Less than 0.20″ expected. High 47°, but tonight’s winds turn colder, and wind chills will approach freezing.
The first half of the work/school week looks pretty good.
The second half not so much.
Storms/Severe?
Flood?
Snow?

Rain should start around or after midnight Wednesday night into the wee hours of Thursday morning. “Should.”
Today our weather is better than New York’s weather and I hope our football team is also, you know, better than the Giants.
(Apologies to my mother in law, who loves Eli Manning, and frankly I respect the dude, my son ran into him last summer and Eli was pure class. May you lose, uninjured, Eli).
Most of Nashville and Will Co stayed just above freezing tonight. Those in far north Nashville, and anyone at elevation, saw icing.

If we were about five degrees colder right now everyone would be:
But, we’re in the mid 30°s, embracing uncertainty as part of the social contract involved in, you know, living here and stuff.
After Will’s morning blog forecast and my Twitter review of model data, NWS-Nashville held a special briefing, the substance of which you’ll read below.
In 6 tweets, this morning I laid out all the model data on Twitter. You can read it here.
