Recap of a rare late-November Mid-South snow storm

It’s still November, but Mid-Southerners have already experienced
the first snow event of the winter season! Thanks to a strong upper-level low
pressure center which developed and moved through the region Monday night, the
right combination of significant moisture and cold temperatures were able to
make a rare early appearance. As a result, rain in the Mid-South began to
change to snow and for some in the area it was enough for a decent
accumulation! In general, it was the first measurable November snowfall in the
region in two decades!
As is typical in Mid-South winter weather events, location
made a great difference in just how much snowfall occurred. The strongest
dynamics of the system, where the heaviest precipitation was able to develop,
set up over a rather localized area and ended up largely north of the Memphis
metro area. Complicating matters further, temperatures during the event were
borderline, with readings generally remaining just above freezing, between 33
and 35 degrees. Additionally, ground temperatures remained well above freezing (in the 40s) due to the very warm temperatures preceding the system – it
was 73 degrees in Memphis on Saturday! These factors served to limit snow
accumulation potential greatly, but in areas where snow was able to fall hard
enough, these limitations were overcome, allowing for accumulations in
grassy areas and elevated and non-paved surfaces. Fortunately, roadways across
the region remained just wet for the most part, resulting in few significant
travel problems.
Across the city of Memphis, snow amounts were minor, a
half inch or less. Memphis International Airport recorded just one-tenth of
an inch of snowfall, with 0.3” recorded at the National Weather Service office
at the Agricenter in East Memphis. Slightly higher amounts, up to 1”, occurred
across northern Shelby County, with 0.6” recorded at MWN headquarters in Bartlett. Other areas of the metro, however, saw more significant snow
accumulations. In Tipton and Fayette Counties, 1 to 2” of snowfall was a common
occurrence, with localized higher amounts up to 2.5” in Fayette County. Amounts
up to 1” also occurred across Crittenden, DeSoto and Tunica Counties.  
The most significant snowfall of this event though was north
of the metro area. Several places in northwest Tennessee, the Missouri
Bootheel, and especially northeast Arkansas saw snow accumulations of 2-4
inches as heavier snow bands redeveloped and persisted in these areas overnight
Monday into early Tuesday morning. There were even isolated reports of up to 6”+ of snow accumulation, nearly hard to fathom for November in the Mid-South! See
the map below for a more complete depiction of snow amounts across the entire region.

Once snow tapered off by Tuesday morning, whatever snow was
left on the ground generally melted away very fast as temperatures recovered to
near 40 degrees. However, to our north where the most significant snow occurred (and
thus took longer to completely melt), visible satellite imagery was able to
detect remnants of snow cover as late as Wednesday morning (see image below). Some
of the most visible (and thus deepest) snow that remained was along the higher terrain of Crowley’s Ridge.

across Middle TN into Alabama.

It’s impossible to say whether this early start to the
winter weather season in the Mid-South is a sign of things to come, but whatever
lies ahead, you can count on MemphisWeather.Net to keep you accurately informed
and up-to-date!
