WINTER WEATHER ALERT DAY: Winter Storm Warning Today

A Winter Weather Alert Day was issued for Tuesday due to a winter storm impacting the ArkLaTex.

A WINTER STORM WARNING was issued for the I-20 and I-30 corridors and everywhere in between. The warning will be in effect through Tuesday mid-day. Widespread snowfall totals across the watch area will range from 2"-3". A few locations could see up to 4" of snow.

A WINTER WEATHER ADVISORY was been issued for Red River Co., TX, McCurtain Co., OK, Sevier CO., OK and Howard CO., OK. The Winter Weather Advisory will be in effect through Tuesday at noon. Widespread snowfall totals across the advisory area will range from 1"-2" of snow.


A strong cold front pushed from north to south across the area earlier this morning. This front brought in a reinforcing shot of cold air and a round of rain and frozen precipitation.

Rain, freezing rain, sleet and snow is now trying to exit the southern parts of the area. The precipitation started out as rain and quickly transitioned into a winter mix of freezing rain and sleet before transitioning into all snow early this morning. The image below matches the approximate time when the rain started to transition into freezing rain and sleet.

Most areas, especially north of I-20, made a quick transition to all snow, which limited ice accumulations. The transition to winter mix happened from north to south across the area.

Keep in mind, road conditions quickly deteriorated this morning and continue to be slick. Slush may refreeze tonight with poor travel conditions again Wednesday morning

As colder air surged into the ArkLaTex, temperatures quickly dropped behind the front. As temperatures dropped to or below freezing, the rain quickly transitioned into a mix of rain, freezing rain, sleet and snow land moved slowly across our area during the morning Tuesday

By midnight, the I-30 corridor made the transition to all snow, while the I-20 corridor started to see some freezing rain and snow in the predawn hours. 

By Tuesday morning, the front  cleared the ArkLaTex and everyone made the transition to all snow.

The snow will wrap up from north to south across the area by mid afternoon Tuesday .


Snowfall accumulations are expected to continue at least through Tuesday afternoon. Widespread snowfall totals of 1-3" plus are expected across the I-20 and I-30 corridors and everywhere in between (the area in dark blue on the snowfall accumulations map below). The very north tip of the ArkLaTex and places south of I-20 (the area in light blue on the snowfall accumulations map below) will likely see an inch or a bit more.

The two major weather models, the European and American or GFS, that we use to forecast showed snowfall accumulations between 1"-2" across much of the area. Plus, both models showed a heavier band of snow setting up between I-20 and I-30. This is the area was under a Winter Storm Warning Tuesday.

Significant ice accumulations failed to materialize. Many streets and highways saw a glaze of ice as snow was melted by traffic.


This system will likely had the biggest impact on travel. Road conditions quickly deteriorated Monday evening through Monday night and traveling was and still is treacherous, especially across the Winter Storm Warning area.

Keep in mind, snow and slush on the roadways may refreeze overnight with lows expected to be from 10 to 15 degrees.

Road closures and school delays and closures were widespread Tuesday morning.

Depending on what happens Tuesday afternoon, road conditions could improve or stay hazardous. This all depends on how soon the snow ends, if the sky clears and if temperatures warm above freezing. Highs on Tuesday will be on either side of 32 degrees.

The latest run of FutureTrack keeps most places well below freezing Tuesday afternoon.

Even though roadways were icy and slick, widespread power outages did not materialize.

Temperatures will tumble into the teens Tuesday night into Wednesday morning. Unprotected pipes could burst. Wednesday will be sunny and everyone will warm above freezing.
