Wintry mix, downpours and gusty storms to threaten Texas following July-like heat

A wintry mix, urban flooding and gusty thunderstorms will accompany a push of cool air across Texas early this week, just days after record heat baked the state.
The thrust of cool air into Tuesday will put an end to the July-like heat that smashed numerous records on Friday and Saturday.
High temperatures in Amarillo plummeted 51 degrees Fahrenheit spanning Saturday to Monday, from the upper 80s to the lower 30s F.
In Dallas, temperatures will drop over 30 degrees from the upper 80s on Saturday to the lower 50s on Tuesday.
A storm pivoting out of the Southwest will run into the fresh chill. Areas of snow, ice and rain will develop as a result.
Snow, ice may cause slick spots from Amarillo to Lubbock
A wintry mix of snow and ice will expand eastward from New Mexico into the Texas Panhandle into Tuesday night.
“As hard as it is to believe, there will be some snow and wintry mix with this storm just days after areas reached or exceeded 90 F,” AccuWeather Senior Meteorologist Dan Pydynowski said.
Given the recent heat, much of the wintry precipitation will melt as soon as it hits the ground.
Still, motorists should not let their guard down, especially on bridges and overpasses where icy spots can develop. This includes along portions of interstates 27 and 40.
“With the recent heat, accumulations are most likely on grassy and non-paved surfaces,” Pydynowski said. “Parts of western Texas will get a slushy inch or two of snow.”
Soaking rain, localized flooding to threaten San Antonio to Dallas, Houston
Soaking rain, locally severe thunderstorms and flooding are forecast farther south and east where it will remain too mild for any wintry weather.
Soaking rain will expand from San Antonio and Dallas to Houston into Tuesday night..
One to 3 inches of rain is expected to fall along this swath.

While much of the rain will be beneficial given the dry start to the month across the South Central states, there can be areas of low-lying and poor drainage flooding.
In addition to the risk of hydroplaning when traveling at highway speeds, motorists could also face slick spots due to oil buildup.
Travel along portions of interstates 10, 20, 35 and 45 could be slower than normal due to reduced visibility.
A handful of the thunderstorms in Texas and Louisiana can turn locally severe and kick up damaging winds and hail on Tuesday. An isolated tornado or two is also possible.
The rain and locally severe thunderstorms will progress eastward along the Gulf Coast and into the lower Mississippi Valley from Tuesday to Wednesday.
