Radar at 4:07 pm shows some light to moderate precipitation driving down I-24 from W Kentucky and S Illinois:

Wx models keep that precip coming. Almost all precip today has fallen as snow flurries, which should continue tonight. The HRRR thinks we’ll be up to an inch of accumulated snowfall as of 4am Tuesday morning. Keep in mind, this is just one weather model, not a forecast, and could be wrong:

But, will it stick?  The NWS think it might, mostly in Davidson County:

MUCH OF NORTHEASTERN MIDDLE TENNESSEE HAS SEEN TEMPERATURES REMAIN AT OR BELOW THE FREEZING MARK THROUGHOUT THE DAY AND BELIEVE HAZARDOUS DRIVING CONDITIONS WILL QUICKLY DEVELOP OVERNIGHT, ESPECIALLY ALONG UNTREATED ROADWAYS, BRIDGES AND OVERPASSES, AS THE SNOW INTENSITY INCREASES. SOME SLIPPERY SPOTS COULD ALSO DEVELOP ALONG ROADS IN OTHER PARTS OF THE MID-STATE, ESPECIALLY NORTH AND EAST OF THE I-24 CORRIDOR (INCLUDING THE NASHVILLE METRO AREA). EXPECT UP TO AN INCH OF SNOW IN AREAS JUST WEST OF THE CUMBERLAND PLATEAU, RANGING TO AROUND ONE HALF INCH IN THE NASHVILLE METRO AREA. read more

Here’s what happened overnight:

Today we may see snow in the air from time to time, some of it falling as rain, some of it as snow. Temps will be above freezing, so we don’t expect it to stick to much – mainly just decks, grills and elevated surfaces – if anything at all.

More of the same tonight.  NWS says:

NASHVILLE WILL BE JUST BELOW FREEZING AND WILL LIKELY WARM UP ENOUGH ON TUESDAY MORNING THAT ANY PRECIP WILL CHANGE TO A RAIN SNOW MIX BEFORE TAPERING OFF FROM WEST TO EAST. TUESDAY NIGHT THROUGH WEDNESDAY CONDITIONS REMAIN DRY AND COOL. read more

No need to panic or party, but seriously, it’s late March and we think it’ll snow tonight and tomorrow night. Counting both nights, look for “around an inch.”

The NWS Graphicast:

Here’s the text for tonight into Monday: “less than one half inch.”

AS FOR THE SNOWFALL ACCUMULATION POTENTIAL...THE FIRST DISTURBANCE WILL EFFECT THE AREA LATE TONIGHT AND INTO MONDAY. AREAS ALONG THE CUMBERLAND PLATEAU COULD SEE ONE HALF TO 1 INCH OF SNOWFALL BY MONDAY AFTERNOON. ACROSS NON PLATEAU AREAS OF NORTHERN MIDDLE TN...ONLY MINOR ACCUMULATIONS OF LESS THAN ONE HALF INCH WILL BE POSSIBLE. ACROSS SOUTHERN PORTIONS OF MIDDLE TN...NO MORE THAN A TRACE IS EXPECTED. read more

Today expect rain this afternoon with a small thunderstorm chance, falling temps tonight, maybe a few snowflakes overnight with little or no accumulation, and a lot of wind. This is “Marchuary” (a term used by Tom Johnstone, who is the Warning Coordination Meteorologist at the NWS in Nashville) at it’s finest. read more

The map below shows rainfall totals under a half inch from Sunday morning through Wednesday morning. Most of this rain will fall this afternoon into Sunday morning and afternoon.  We may see a stray thunderstorm or two, but nothing to worry about. read more

There’s still a small chance these models are wrong, but on this they agree: no rain until around dusk tonight, probably later.
