Wintry weather heading to North Texas

Monday, January 15, 2018

The National Weather Service on Sunday afternoon issued a Winter Weather Advisory and Winter Storm Watch for parts of North Texas for Monday night through Tuesday morning.

While overall accumulations don't look to be very high across North Texas, any accumulations of ice, sleet, or snow will likely cause problems. So, we do have concerns for a slow and slippery commute Tuesday morning.

TxDOT and North Texas Tollway Authority crews pre-treated highways several days ago with a brine substance, but both agencies will have crews on standby Monday.

THE TIMING:

A shot of arctic air moves into the area Monday afternoon and evening. Ahead of this strong cold front, light rain is possible between 3 p.m. and 7 p.m. Monday. The arctic air will continue to spill into North Texas and any moisture left behind the front will transition to a wintry mix Monday evening.

Depending on the timing of the front, the Monday evening commute could be a little slick for parts of North Texas. Right now, that risk is higher NORTH of DFW. But there's also a chance that those areas stay fairly dry Monday evening. However, if you have any plans after 7 p.m in and around DFW, a transition to a wintry mix is likely during that timeframe. Eventually, late Monday night, we’ll see a transition to light snow. That could linger through Tuesday morning especially in the southern part of North Texas. Any snow will end from north to south during the morning hours on Tuesday.

ACCUMULATION:

Totals will be tricky because they will likely be a mix of sleet and snow, and the timing of dry air moving into North Texas. As of now, a dusting to less than a half-inch is possible for areas north/northwest of DFW to the Red River (Denton, Decatur, Jacksboro, Gainesville, Bowie). While some slick spots are possible in those areas just mentioned, travel issues are not very likely. Up to a half-inch of a sleet and snow mix is possible for DFW and to the west (areas under the Winter Weather Advisory). Slick spots are likely in areas under the Winter Weather Advisory, but widespread, hazardous travel is less likely. The highest totals will be in areas east and south of DFW (areas under the Winter Storm Watch). These locations could pick up a half-inch to one inch of a sleet and snow mix. There also could be a band of higher amounts (1-2 inches) for areas around and near Mexia to Corsicana to Athens to Tyler and farther east into East Texas). Hazardous and the most widespread travel problems will be in areas under the Winter Storm Watch.

BEHIND THE FRONT:

We'll wake up Tuesday morning to temperatures in the lower 20s and upper teens. Wind chills Tuesday morning will be in the single digits to low teens. Regardless of whether or not you have any sleet or snow on the ground, it'll be COLD to start Tuesday. Highs Tuesday afternoon will only climb to the upper 20s and lower 30s. Most of North Texas will not get above freezing. By Wednesday morning, lows will fall into the teens.

Temps will not warm up above freezing until around midday or early afternoon on Wednesday for most. There's a chance far northern and northeastern parts of North Texas could stay below freezing through Wednesday afternoon as well. 

COMPLICATIONS:

If the front moves through a little quicker and drier air moves in a little faster than it looks right now, that could push most of the wintry weather farther to our south. The northern half of North Texas including DFW would likely stay fairly dry, while the southern half would still see wintry weather. 

Continue to check back to the forecast! Not everyone will see delayed or canceled school Tuesday morning or impassable roads. While cancellations are certainly possible and roadways will be icy or slick for parts of North Texas, it's too early to know those exact details. Be prepared and stay in the know!
