More of our models are coming into agreement on the possibility of a hard freeze for our area Friday and Saturday morning. A sleet-snow mix is also coming into focus for Wednesday evening into Thursday morning. The Arctic air will cause temperatures to plunge during the day Thursday. By Friday morning even Galveston could see frost on the vegetation that survived Ike. The low temperatures on Galveston island could be in the upper 20s by Friday morning. The temperatures in Houston will range from the mid to upper 20s with teens from Huntsville to Brenham. If the early December frost of 2009 didn't impact your home and garden, this air mass has a better chance. The temperatures may be below freezing for several hours through the weekend. Take steps now to protect your pipes, plants and pets. Please check to make sure elderly friends and neighbors are ready for this extended period of cold weather.
