Baby, it's cold outside! In fact, the coldest temperatures in just shy of three years have moved into Houston.

As of 7 a.m. Saturday, the mercury plummeted to 21 degrees at Bush-Intercontinental, 23° at Hobby, 19° in Conroe, 19° in The Woodlands, 20° in Sugar Land and 31° in Galveston.

Even under bright sunny skies temperatures will struggle to get out of the 30s today and in many cases they won't.

In preparation for the freeze, the National Weather Service has issued a Hard Freeze Warning for every county except Galveston. A Freeze Warning is in effect for Galveston county and Galveston Island. All the advisories are in effect until Sunday morning.

A hard freeze is defined as temperatures dropping to or below 27 degrees for a couple of hours. That should be an *easy* accomplishment.

Temperatures area wide will range between 15 and 25 degrees, colder to the north and west, and Galveston will hover around 31 degrees. Wind chills will hover in the single digits above zero and low teens area wide.
