URGENT - WINTER WEATHER MESSAGE
National Weather Service Brownsville TX
647 PM CST Sat Feb 13 2021

...HAZARDOUS WINTER WEATHER IMPACTING DEEP SOUTH TEXAS THIS
THROUGH MONDAY...

.An upper level trough of low pressure will be approaching
southern Texas from the west. As this low pressure area moves
across the region Sunday and Monday, another surge of Arctic air
will move into the region from the north. This will cause
temperatures to drop lower Sunday Night into Monday likely
falling below the freezing mark for several hours. As the trough
of low pressure moves through the region, the precipitation
chances will increase beginning tonight. This in combination with
the Arctic airmass will set the stage for freezing or frozen
precipitation Tonight, Sunday Night and Monday. The precipitation
will likely be a cold rain early tonight and during the day
Sunday, and will then start to mix with or change over to sleet
or freezing rain from overnight tonight and again Sunday evening
through Monday morning. The precipitation should start decreasing
across the region Monday afternoon and evening. Also, The
combination of steady northern winds and cold temperatures today
will produce Wind Chill Values across the inland portions of Deep
South Texas and the Northern Ranchlands dropping into the 20 to
30 degree range into this evening with wind chills on Sunday into
Monday in the 10 to 20 degree range.

URGENT - WINTER WEATHER MESSAGE
National Weather Service Brownsville TX
424 AM CST Sun Feb 14 2021

...HAZARDOUS WINTER WEATHER EXPECTED ACROSS DEEP SOUTH TEXAS 
THROUGH MONDAY...

.A surge of arctic air continues to arrive into Deep South Texas 
through this evening, dropping temperatures below freezing 
tonight. Temperatures will struggle to reach or warm above 
freezing on Monday, before a hard freeze is expected Monday night.
An upper level disturbance will help increase precipitation into
tonight before drying from west to east Monday morning. At times
this morning into this afternoon, especially across the 
northwestern ranchlands, sleet or ice pellets may mix in with rain.
As temperatures at the surface drop to freezing this evening into
tonight, any rainfall will become freezing rain, potentially 
mixed at times with sleet or ice pellets. A glaze to one tenth of 
an inch of ice accumulation is likely by Monday morning, causing 
significant impacts to travel. Snow flurries or light snow may mix
in Monday morning across portions of the northern ranchlands
before ending from west to east, with little to no snow 
accumulation expected at this time. The combination of steady 
northern winds and cold temperatures will produce wind chill 
values into the 20 to 30 degree range this morning, and again 
this evening, before dropping into the 10 to 20 degree range late
tonight.

URGENT - WINTER WEATHER MESSAGE
National Weather Service Brownsville TX
604 AM CST Sun Feb 14 2021

...HAZARDOUS WINTER WEATHER EXPECTED ACROSS DEEP SOUTH TEXAS
THROUGH MONDAY...

.A surge of arctic air continues to arrive into Deep South Texas
through this evening, dropping temperatures below freezing
tonight. Temperatures will struggle to reach or warm above
freezing on Monday, before a hard freeze is expected Monday
night. An upper level disturbance will help increase
precipitation into tonight before drying from west to east Monday
morning. At times this morning into this afternoon, especially
across the northwestern ranchlands, sleet or ice pellets may mix
in with rain. As temperatures at the surface drop to freezing
this evening into tonight, any rainfall will become freezing
rain, potentially mixed at times with sleet or ice pellets. A
glaze to one tenth of an inch of ice accumulation is likely by
Monday morning, causing significant impacts to travel. Snow
flurries or light snow may mix in Monday morning across portions
of the northern ranchlands before ending from west to east, with
little to no snow accumulation expected at this time. The
combination of steady northern winds and cold temperatures will
produce wind chill values into the 20 to 30 degree range this
morning, and again this evening, before dropping into the 10 to
20 degree range late tonight.
