It’s no secret by now that freezing precipitation may be headed toward southeast Texas. The big question is how serious is this threat to Galveston County? The short answer is that the chances of having to deal with freezing rain and sleet will be moderate to high in the northwest part of the County and progressively lower as you near the coast and Galveston Bay.
An Arctic front will plunge deep into Texas on Thursday. As the cold air moves in, warmer air aloft is expected to produce a classic over-running situation, with clouds and precipitation. Precipitation should start as rain, but may shift to sleet or freezing rain by early Friday as temperatures dip to the freezing mark. Snow will be possible, though the best chances will be off to the north of Galveston County and extending eastward into south-central Louisiana.
