Temperature dips to 22 degrees; another hard freeze coming; road closure information

Technically, it could be called a snow day.

Harry P. Williams Memorial Airport reported light snow and freezing rain between midnight and 2 a.m. Tuesday as the mercury was on its way to 22 degrees by 7 a.m.

The temperature was expected to stay below freezing until about noon, which would be about 17 hours at or below 32 degrees. The low was headed for 23 degrees again by Wednesday morning, but without the precipitation.

St. Mary public schools, Central Catholic and South Louisiana Community College called off classes Tuesday. No announcements have yet been made about Wednesday.

Ice collected on vehicles parked outdoors overnight. The U.S. 90 bridge remained open, but minor crashes were reported there overnight.

U.S. 90 was closed in Lafourche and Terrebonne parishes because of ice. Farther north, Interstate 10 was closed between Lafayette and Lobdell, also because of ice.

The high temperature is expected to be 47 degrees Wednesday and 65 degrees Thursday.
