Frost/Freeze in Kenedy, Texas

After rain changed to snow just before daybreak on December 8th, temperatures fell to or just below 32 degrees for several hours during the morning. Observations included both Armstrong (30 degrees) and Sarita (31 degrees), making the case for the winter of 2017/2018's first light freeze.

A pattern known as a modified McFarland brought a modified polar air mass across all of Deep South Texas and well into northeast Mexico in the lee of the Sierra Madre Mountains. The polar air changed rain to snow, some which fell heavy enough in a stripe from southern Zapata, northern Starr, most of Jim Hogg, and western Brooks County to bring several hours of 32 degree or lower temperatures.
