Although somewhat unlikely, we find ourselves in a winter pattern this morning similar to those that have produced sleet or snow in Galveston County over the years. One major difference is that temperatures are running 5-10 degrees warmer than is typical for such snow or sleet events over Southeast Texas.
Still we find ourselves with a possibility that Galveston County residents could see some sleet pellets or snowflakes this evening or overnight. The chances of any accumulations locally, however, are quite slim. Most likely the sleet or snow would be melting as it falls, with ground level temperatures and soil temperatures too warm to support any accumulations or icing.
Nevertheless, an upper-level disturbance tracking east from northern Mexico and southwest Texas, is producing snow and sleet over the mountains of northern Mexico and southwest Texas and reports of a few flurries have even popped up around the Del Rio and southwest Hill Country as well as closer to San Antonio.
What makes the situation intriguing is a reinforcing surge of colder air expected to reach Galveston County tonight. With precipitation lingering near the coast, this may be just enough to allow some of the snow and sleet to reach the ground before melting.
So, while the chances of seeing this remain somewhat remote, it is certainly something that cannot be ruled out completely as of this morning.
