URGENT - WINTER WEATHER MESSAGE
National Weather Service Shreveport LA
448 AM CST Mon Jan 11 2021

...A few lingering snow showers remain across the area, slick
conditions will continue for this morning's commute...

.While the snow is coming to an end across much of the area this
morning, there remains some concern of slick conditions through
the morning commute, especially on elevated bridges and
overpasses. With temperatures not expected to warm much through
the early morning hours, we have extended the Winter Storm Watch
and Winter Weather Advisory through 10:00 AM CST. General thinking
is that road conditions should begin to improve around this time.
