Bottom Line

Additional freezing rain and sleet accumulations will worsen roadways areawide with travel not advised today and Wednesday. The axis of greatest additional sleet and ice accumulations Tuesday has shifted to along and south of a Goldthwaite-Hillsboro-Sulphur Springs line. Conditions start to improve east of I-35 Wednesday afternoon and area-wide Thursday afternoon.

Overview

• Any water on the roadways from yesterday’s precipitation has frozen overnight, worsening travel impacts today.
• More widespread freezing rain and sleet is expected today with significant accumulations of ice expected. Road conditions will steadily deteriorate.
• Even a thin glaze of ice can cause you to lose control of your vehicle.
• Another round of sleet, freezing rain, and rain will return Wednesday.
• Conditions may improve Wednesday afternoon, particularly across the southeast.
• Light freezing rain will continue Thursday morning, primarily across western North Texas. 
• In combination with the refrozen water on the roads, the Thursday morning commute will be impacted for those mainly west of U.S. 75 and the I-35 corridor. 
• A transition to all rain will occur by mid-morning Thursday with rain ending west to east Thursday afternoon/evening. 
• The Winter Storm Warning has been extended through 6 a.m. Thursday.

What We Are Certain Of:  

• Multiple rounds of precipitation will occur through Thursday across all of North and Central Texas.
• Much of this will be freezing rain and sleet, resulting in ice accumulations across much of the region.
• There will be significant impacts to travel.

What We Are Less Certain Of:

• Where exactly the axis of greatest freezing rain and ice accumulations will occur. 
• Where and how long temperatures may remain below freezing.
• If heavy rain on Wednesday will allow travel conditions to improve. Heavy rain cores may bring warmer temperatures above the surface down. Periods of heavy rain could also melt
