Jacket and sweater weather again this morning across South Florida as our cold snap continues. National Weather Service meteorologist George Rizzuto says we are waking up with highs in the mid to upper forties. The cold front continues on through tomorrow morning, but temperatures will start to slowly head back up Friday afternoon. Don't be surprised if your tire light comes on. As temperatures drop, tire pressure decreases. For every ten degrees Fahrenheit change, tire pressure changes by one-to-two pounds per square inch.
