Severe weather threat subsides, Winter Weather Advisory in effect through 12 p.m. Sunday

The severe weather threat has since subsided, but with freezing temperatures moving into the Valley, a wintry mix is possible through Sunday afternoon.

Refresh this page for the latest radar image:

  • The Winter Weather Advisory now includes a large part of Tennessee and several counties in North Alabama: Colbert, Lauderdale, Limestone, Madison and Jackson. The forecast has not changed: very little (if any) impact from winter weather in the WHNT News 19 viewing area.
  • A few slick spots may develop in areas that have trouble drying off after a heavy rain (i.e., areas where natural springs develop after a 1-2″ rain).

With that said, below is a recap of the severe storms and gusty winds that moved through the Valley late Saturday into Sunday morning.

An error in the NOAA Weather Radio system may have led to some radios not toning the ‘watch’ a little while ago.  The NWS is working on that problem; just like last time, HAVE A BACK-UP to weather radio.  Live Alert 19 offers GPS specific warnings (not just counties), and there’s no programming involved.  www.whnt.com/apps

Mesoscale Discussion 1898
NWS Storm Prediction Center Norman OK
0230 AM CST Sun Dec 18 2016

Areas affected…Northeast MS…far northwest AL…west and middle
TN…central to northeast KY…and southern OH

Concerning…Freezing rain

Valid 180830Z – 181230Z

SUMMARY…Surface temperatures will continue to fall overnight in
the wake of the cold front. As readings fall below 32 F, freezing
rain with rates of 0.05-0.10 inches per hour will continue to be the
initial wintry precipitation-type, as a 70-100 mile wide swath of
stratiform rain spreads across the discussion area through 11-12Z.
Sleet should mix in from west to east as the cold air deepens.

DISCUSSION…Strong low-level cold air advection will continue in
the post-frontal air mass across the discussion area from northern
MS to southern OH overnight, as the cold front advances toward the
Appalachian Mountains. Trends in mosaic radar imagery indicated a
70-100 mile wide swath of stratiform precipitation in the wake of
the cold front. As surface temperatures fall below 32 F in this
post-frontal air mass, a residual warm layer above the surface will
support freezing rain as the primary precipitation type as has
already been observed in northern MS through west TN, southwest KY
to central OH. Precipitation rates of 0.05-0.10 inches per hour
will be common, though locally higher rates cannot be ruled out.
Meanwhile, forecast soundings suggest as the vertical thermal
profile cools in the lower-troposphere, the warm nose will diminish
allowing sleet to mix in and or become the primary precipitation
type.
