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

...The Winter Weather Has Ended...
...Bitterly Cold Tonight...

.The winter weather has ended, however very little melting will 
have occurred through Monday afternoon. This will lead to 
extremely hazardous roadways across the region as snow and sleet 
form icy conditions. Icy roads will remain a concern through early
Wednesday.

Low temperatures tonight will range from the single digits to near
20. These temperatures combined with northwest winds of 5 to 15
mph will produce wind chills of 5 below zero to 15 above zero. The
lowest wind chills will generally be north of a Silsbee to Buna
line in Southeast Texas and north of Highway 190 in Louisiana.

...Bitter Cold This Morning...
...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 
winds of 5 to 15 mph will produce wind chills of 5 below zero to 
15 above zero. The lowest wind chills will generally be north of a
Silsbee to Buna line in Southeast Texas and north of Highway 190

Another round of wintry precipitation is expected to affect the

morning. Locations across the Texas lakes region and Central
Louisiana will see areas of freezing rain develop after midnight
tonight, with rain continuing and increasing in intensity on

Temperatures are currently expected to climb above freezing for a
short time period Wednesday afternoon in this area, but are
expected to fall below again Wednesday night. Accumulating ice is
currently forecast, with a greater than 50 percent chance of
totals reaching or exceeding one quarter of an inch.
