||A developing cold front, associated with the creation of the December Blizzard of 2010 from New Jersey to New England, pulled down dry, Canadian air with strengthening high pressure overnight on December 25th and well into the morning hours of December 26th. Breezes through the post midnight hours kept temperatures a hair above freezing in many areas, but calming winds by 2 AM or so allowed temperatures to fall more steadily, continuing for an hour or two after sunrise.
Lows fell well into the 20s in sheltered locations of rural Deep South Texas, and even reached 32 or lower in populated areas of the Lower and Mid Rio Grande Valley. The coldest temperatures of the winter thus far were felt from McAllen to Harlingen and Brownsville, where temperatures fell to a hair above freezing. For the lower Valley, all non urban areas west of highway 77 saw freezing temperatures on the 26th.
||The Automated Weather Observing Station at the Brooks County Airport just southeast of Falfurrias recorded more than 4 hours of freezing temperatures, falling to 27 degrees just after daybreak on the 26th. Proxy observations near Sarita and Armstrong in Kenedy County/King Ranch fell to 27 and 25 degrees, respectively. The Lower Rio Grande Valley National Wildlife Refuge Remote Automated Weather Station near San Manuel also reached 25 degrees, with freezing temperatures for just under 5 hours.
