This is your official “wintry mix” alert for Houston.

Like we told you last week, the National Weather Service says a cold front making its way through Texas could bring a mix of rain and snow to areas north of the Houston metro Wednesday night. But don’t put on your parka and scarves just yet – showers and thunderstorms with the possibility of hail are expected to impact the Greater Houston ahead of the front Tuesday night.

Relatively light showers will move in Tuesday evening, which increases to possible thunderstorms into the night as the front pushes off the coast, meteorologists say. Wednesday morning will be wet commute for drivers, but the skies will clear as the day goes on, according to NWS.

Temperatures on Tuesday could reach the low 80s in parts of the Greater Houston area. Wednesday’s daytime temperatures north of Houston will barely break 40 degrees while coastal communities will be in the 70s early in the day.

As cooler air moves in, showers could develop – which could turn into a wintry mix of rain and snow for counties north and northwest of Houston, including Montgomery, parts of Waller, Walker and Brazos counties, meteorologists say. Whether the frozen precipitation will stick to the ground remains to be seen.
