Ice remains. It was 5° at BNA overnight. Many local areas colder than that.
Temps above freezing – barely, briefly – this afternoon. Sunlight and light winds will erode but not eliminate ice sheets. Back down to 20° overnight and Monday morning.read more
Most main and secondary roads are OK, but could contain “invisible” black ice in “hard freeze” (T<26°) temps today and Sunday morning. Neighborhood roads, sidewalks and decks remain icy, esp on hills and in shady areas. read more
Wind Chills “as low as minus fifteen” (-15°) expected.” -NWSNashville.
Winds could “result in hypothermia if precautions are not taken.” -NWSNashville.
Any traveling vehicles need full weather clothes, flashlight, food, water should you slide off icy roads. If you crash you’ll need supplies.
Tues morning temperature low: 7°. Weds morning low 2°. TWO. Wind chills will be much colder of course.
Snow Totals Vary 5.5″ to 9.5″. Snow fell unevenly. Elevation and location skew results. I’ve seen 5.5″ to 9.5″ in our replies. An average winter in the last 30 years delivered 4.7″. Snowfall is ending now and should be gone after dark. Send measured snow taken from hard surface (not grass) by tagging it with #tSpotter on Twitter. read more
Morning rain will end during lunch. A few hit/miss showers may drive by your place this afternoon, otherwise cloudy with a few breaks of sunshine for some. HRRR model through 7 PM today below:
Colder air later this week, wind chills near freezing Weds morning with colder mornings after that. read more
National Blend of Models predicts 2″ of rain this weekend.
BEST GUESS TIMING. Most likely start time between 6 PM to midnight Saturday night. Ending around lunch Sunday. It’s possible rain could arrive as early as noon Saturday and end earlier Sunday morning -or- start later Saturday night and linger into Sunday afternoon. read more
1. Brief, chilly, and unevenly rainfall caused by – impress coworkers at holiday parties with a well timed – this “is common for these clipper systems.”
2. Rainout/Washout unlikely.
3. You may hear talk of “snow” — that’s for non-accumulating snow potential on the plateau.
4. GEO ICYMI: The plateau is east of us – think between Cookeville and Crossville – they’re at higher elevation – easier for them to snow than us.
Near/Freezing Morning Temps & Thursday’s Marginal Fire Danger
1. Ice may form where fog develops on bridges and overpasses Weds & Thurs mornings.
2. A marginal fire danger Thursday afternoon will discourage outdoor burning – dry airmass with low relative humidity + winds in the low teens = may cause fire containment problems.
Big Rainmaker Coming This Weekend
1. TIMING: best guess right now arriving Saturday night and departing around lunch Sunday – timing will probably change.
2. RAIN: on average 1″ to 1.5″ – this too may change either way – models diverge in key areas – this reduces forecast confidence.
3. STORMS: again our confidence is shaky here due to model disagreement – the path of the storm favors thunderstorms – but other essential ingredients (instability, lapse rates) are very weak in the models – SPC excluded us from severe weather risk – no risk will be introduced unless and until models develop agreement – more to follow later with new data.
4. SNOW: not for us – our ground will be way too warm – unreceptive to ice – models at this range routinely advertise snow that never happens – even the Euro (above) pulls the colder air columns way too far north of us.

Monday morning. HRRR has a weak rain band tomorrow (Monday) morning. Inconsequential.
2. Tuesday morning. Cold brief rain if the HRRR is right (model cuts off before arrival):
3. Weekend rain. Timing and “accuracy” iffy at this range. A soaker is best bet. Not sure if Saturday or Sunday or both. May involve thunderstorms but no current severe concerns. Notice those pinks and blues as the system moves away – common false flag for wintry precip. More about this system tomorrow. read more
