URGENT - WINTER WEATHER MESSAGE
National Weather Service Lake Charles LA
403 AM CST Sun Feb 14 2021

...Increasing Confidence in the Potential for a Significant 
Winter Weather Event Tonight into Monday...

.An upper level disturbance will bring abundant moisture tonight 
and continuing into Monday. Meanwhile a very cold air mass will be
in place at the surface. Therefore, any rain is expected to 
become freezing rain and sleet as early as after sunset today,
then increase in intensity overnight into Monday morning. The 
precipitation will change over to snow and sleet for portions of 
the interior southeast Texas and west central Louisiana overnight 
and early Monday morning, with some snow mixing in for the 
remainder of the area mid to late Monday morning into Monday 
afternoon. The winter precipitation will gradually end during 
Monday afternoon. 

The expected winter precipitation amounts, especially ice 
accumulations, will have the potential to produce significant 
impacts.

Bitterly cold arctic air will then move in as the precipitation
ends. Dangerously cold wind chills will accompany this arctic air
for Monday night into Tuesday morning.

URGENT - WINTER WEATHER MESSAGE
National Weather Service Lake Charles LA
416 AM CST Mon Feb 15 2021

...A Significant Winter Weather Event is in Progress...

.An upper level disturbance will bring abundant moisture through
the morning hours over a very cold air mass at the surface. This
will produce widespread freezing rain, sleet, and snow. Some 
thunderstorms will also occur producing periods of heavier
precipitation. The winter mix will gradually end from west to 
east by the afternoon.

The expected winter precipitation amounts, especially ice and
sleet accumulations, will have the potential to produce 
significant impacts.

Bitterly cold arctic air will continue to move in as the 
precipitation ends. Dangerously cold wind chills will accompany 
this arctic air through Tuesday morning. 

Also, with the frigid temperatures, any leftover moisture on
surfaces will freeze, and not allow for any significant melting 
of the winter precipitation accumulation.

...Another Round of Wintry Weather Possible for the Texas Lakes
into Central Louisiana...

.Temperatures this morning tonight will range from the single 
digits to near 20. These temperatures combined with northwest
