Updated at 4 p.m.: Revised to include hard freeze warning.

Most of the Dallas-Fort Worth area appeared to escape the brunt of icy weather Tuesday morning, but areas to the south and east were hard hit.

Temperatures were expected to remain in the teens and 20s Tuesday, with wind chills in the single digits, according to forecasters at the National Weather Service in Fort Worth.

Temperatures should stay below freezing until Thursday, when the high is expected to reach the mid-40s, KXAS-TV (Channel 5) reported.

Most roads in the Dallas-Fort Worth area remained dry and clear on Tuesday morning.

A winter weather advisory scheduled until noon in Dallas-Fort Worth was canceled early Tuesday as conditions were better than expected.

But frigid temperatures prompted the Weather Service to issue a hard freeze warning Tuesday afternoon for all of North and Central Texas. It will be in effect from midnight to 10 a.m. Wednesday. Temperatures are expected to fall to around 10 degrees overnight.

A Hard Freeze Warning is in effect for all of N & C TX tonight! Lows will be in the single-digits & teens. Remember to protect people, pets, pipes, & plants! Also, dress in layers if you are going to be outside for a prolonged period of time! #dfwwx #ctxwx #txwx #texomawx pic.twitter.com/640onlajNP — NWS Fort Worth (@NWSFortWorth) January 16, 2018

More than 200 schools and school districts announced they would be closed on Tuesday, but many in the Dallas-Fort Worth area operated on a normal schedule, including Dallas ISD.

A few districts, such as Mansfield and Fort Worth, opted to begin classes two hours later than usual, while Grand Prairie called for a Flipped Learning Day for staff, in which teachers were encouraged to work from home. Tuesday was already scheduled as a staff development day and student holiday, Grand Prairie ISD spokesman Sam Buchmeyer said.
