Snow again! Recap of the 2nd Mid-South snow event of winter ’11-’12

It may seem like déjà vu, and it’s still not even officially
winter yet, but for the second time in just nine days, accumulating snow has
made a visit to the Mid-South! With another upper level disturbance moving
across the region overnight through Wednesday morning, precipitation which
broke out Tuesday evening across central Arkansas began to move into the metro
area. As colder temperatures and stronger upper-level dynamics moved in, light rain quickly changed to snow and the result was another decent accumulation
event for much of the metro. For some areas, snow amounts were heavier than
seen in the November 28-29 event, even though the event did not get nearly the hype prior to onset.

While it may have been a surprise to some,
computer models came into agreement on the likelihood for snow
accumulation in the area on Tuesday morning. Given the higher confidence presented by the model solutions, MemphisWeather.Net ramped up our snow forecast accordingly during the day and pretty much nailed the event by Tuesday evening.  In fact, in this blog post, we provided a window of 1-3am for snow onset and 10am for an end time.  Memphis Int’l Airport officially switched over to snow at 2:11am and the snow ended at 10:18am!  We also predicted about an inch on grassy and elevated surfaces last night. While some locations in the northern metro got about 3″ of snow, the official observation from Memphis was 1.3″ with many metro locations reporting 1.5-2.0″.

Similar to the November 28-29 event, temperatures throughout
the duration of snowfall were borderline, with readings near the freezing mark.
This meant that snow accumulation once again mainly occurred on grassy
surfaces and elevated or non-paved surfaces. However, where heavier snow fell
and temperatures briefly dipped to 31-32, some slush did accumulate on roadways in outlying areas and on a few bridges and overpasses
area wide. Fortunately, travel impacts still remained limited overall.
In the city of Memphis, snow amounts were more significant
compared to last week’s event, with several locations recording 1 to 2 inches
of total accumulation. Memphis International Airport received 1.3”, with 1.8”
at the National Weather Service in East Memphis. Other locations in Shelby
County received similar amounts, and these amounts were also common in the
other metro counties. Higher snow totals were found across portions of Tipton
and Fayette County, another similarity to last week, with some localized areas
reporting unofficial accumulation of 3 to even 4 inches!  Some pics we took this morning are below.

The system responsible for the snow began moving east of the
metro by mid-morning, bringing an end to the precipitation. Once snow ended,
temperatures began warming back above freezing and snow quickly started melting.
By late afternoon, patchy areas of snow on grassy surfaces were about the only
remnant left from this morning’s snow event and clouds were just moving out, creating a nice sunset for many to enjoy.

It’s certainly been an early and active start to the winter
weather season in the Mid-South! If you don’t want to be surprised by another snow storm, be sure to stay updated with MemphisWeather.Net.  We’ll keep you posted on all weather threats and potential impacts, including any potential for winter weather over the next few months.
