NORTH TEXAS (CBSDFW.COM) – As we ring in 2019, a colder airmass will continue to settle into North Texas.
Temperatures on Tuesday will be 20° colder than Monday and this cold air is here through the mid-week, CBS 11 Chief Meteorologist Scott Padgett said.
There are a number of factors to look at with the potential winter mix on Wednesday into Thursday.
Right now the Upper Level Low pressure system is near Arizona and is slowing down and moving a bit further south than originally forecast. What that means is there is a better chance now to see a mix of a cold rain/freezing rain in North Texas on Wednesday into Wednesday night and now, most of Thursday.
Wednesday morning between 3:00 a.m. and 5:00 a.m. we will start to see scattered rain/freezing rain mainly along the I-35 corridor and west. By noon Wednesday, the freezing line will shift west and the freezing rain potential also shifts west of the I-35 corridor.
A very cold rain will remain in most of North Texas but the freezing rain/rain mix will be near and west of Highway 281.
Late Tuesday night a Winter Storm Watch goes into effect for our western counties and remains in effect until 6:00 p.m. Wednesday. This lines up with the biggest ice accumulation potential of 0.10”-0.25” being west of the metroplex and west of Highway 281.
As the upper level low moves into the Southern Plains and tracks over or slightly north of North Texas, we will still see a cold rain & freezing rain mix on Thursday morning. The mix will mainly Stay west or near 281 with a cold rain remaining over the majority of North Texas.
Late in the day Thursday, the precipitation will start to break up and be more scattered and by Friday afternoon we will see more sunshine and warmer temps.
Remember that with these winter systems, a small shift in the track and speed could mean a difference in one area seeing only rain and another area 25-50 miles away seeing the winter mix. Stay with your Texas Weather Experts as we continue to monitor and analyze this developing storm.
Meantime, TxDOT and NTTA began pre-treating highways across North Texas Monday in anticipation of possible freezing rain.
Crews in trucks spread a brine mixture with the goal of preventing ice from sticking to the roads.
TxDOT said it’s treating main lanes, bridges and overpasses ahead of the potential wintry weather.
Drivers are asked to be conscious of the trucks on the road and give them plenty of space.
