More than 40 million people remain under winter storm alerts this morning, which include ice storm warnings, winter storm warnings, and winter weather advisories that stretch from southeastern New Mexico to West Virginia. 

Additional rounds of heavy icing are expected today across portions of Texas through the Tennessee River Valley. 

Cities under the ice storm warnings include Memphis and Little Rock. Meanwhile, Dallas, San Antonio, San Angelo and Waco remain under winter storm warnings.

“Multiple rounds of wintry precipitation are forecast, with brief lulls followed by bursts of sleet and freezing rain that could drastically deteriorate road conditions,” the Weather Prediction Center said this morning.

Ice accumulations of one-tenth of an inch to three-tenths of an inch have already been recorded across portions of Arkansas, Texas and Kentucky since yesterday. 

“The Tuesday morning commute could become treacherous, especially in areas where residual moisture/slush from yesterday's wave of precipitation has refrozen,” the National Weather Service office in Fort Worth said.

The heaviest ice accumulation of one to three quarters of an inch is forecast across a large portions of Texas through Thursday morning. However, a more widespread swath of one quarter of an inch of ice is possible across southern Oklahoma, Arkansas, northwestern Mississippi and portions of Tennessee.

“The next widespread wave of precipitation looks to develop by late Tuesday night into Wednesday morning,” the weather service office in Fort Worth said. “Wednesday night and Thursday should be the final hurrah of this prolonged Winter Storm.”
