Refreeze could cause problems on the roads Wednesday morning

PITTSBURGH — UPDATE 11 p.m.: Make sure you check the driveway, sidewalks and front steps before you head out because refreeze will be an issue in the morning.

And you’ll have to slow down when it comes to bridges and on-ramps as well.

The reason is that cold air is moving above and below those elevated surfaces, so it’s going to cool off faster or keep it cold.

Experts said even treated surfaces could be a problem if you don’t have the right product or get more snow.

Also, the thermometer in your car doesn’t give you the road temperature, and that’s what determines if the road freezes or if the snow will stick.

If the road looks wet, slow down because it could be black ice.

One more thing -- make sure you pay attention to those yellow signs that read “bridge may ice in cold weather.”

Give yourself a little extra time in the morning for the roads and other drivers on the road.

One family said the first snow of the year is always beautiful.
