What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area Forecast Discussion
National Weather Service Memphis TN
502 AM CST Mon Dec 6 2021

.DISCUSSION... /issued 439 AM CST Mon Dec 6 2021/

Cool, dry and seasonal early December weather will prevail across
the Midsouth through midweek, following this morning's cold
frontal passage. Strong northerly winds will lighten overnight,
but probably not go completely calm, as surface high pressure
settles into Illinois. These light winds and dry air (lower to mid
20s dewpoints), should preclude fog/freezing fog formation late
tonight.

Fast zonal flow aloft will prevail until a weak upper trof passage
early Wednesday morning. This feature should pass through the
area dry, given the lack of return flow moisture in the Midsouth.
Main impact would be an increase in midlevel clouds.

Zonal flow an low amplitude ridging will prevail Thursday and
Friday, with strengthening low level return flow. Milder overnight
lows will accompany increased surface dewpoints. A few showers
will also be possible, aided by warm advection.

A progressive longwave trof remains on track to pass from the
plains into the MS River valley on Saturday. This feature will
bring our next appreciable rain chances, and perhaps a few strong
storms. Dry conditions should for Sunday, with upstream ridging
set to move into the Midsouth early next week.

.AVIATION...

12Z TAF Set

Convection along and ahead of a cold front will continue to sink
southeastward across the Mid-South this morning. IFR/MVFR
conditions will occur with the convection. Expect conditions to
improve to VFR pretty quickly behind the front. Gusty Northerly
winds will occur behind the front as well. Expect speeds sustained
at 12-16 KTS with gusts up to 25 KTS. Speeds will begin to
diminish around sunset as the direction begins to shift to the NE.
