Episode narrativeepisode_narrativeA true blue norther drove pure Canadian high pressure directly into South Texas and northern Mexico, beginning on November 27th and continuing through early on the 29th before the high drifted into the southeast U.S. Extremely dry and relatively chilly air invaded Deep South Texas and the Rio Grande Valley; temperatures bottomed out in the mid 20s to lower 30s for all but the southeast corner of the Rio Grande Valley on the 28th.||The event was a rare dry freeze, as humidity through the coldest periods remained below 50 percent. Ambient temperatures varied greatly depending on the height of the sensor taking the measurements. At eye level, temperatures fell to or just below freezing in many areas, but remained a few degrees above freezing in others. Just above the ground, and in wind protected hollows, temperatures fell into the 20s; local hard freezes, defined as 2 or more hours with temperatures below 28 degrees, likely occurred. Agricultural damage was not known as of this writing.
Event narrativeevent_narrativeTemperatures fell below freezing in wind protected areas, including the Zapata County Airport (near Medina, northeast of Zapata), shortly after 5 AM and continued until 8 AM on the 28th. Minimum temperature at the airport was 27 degrees. A Remote Automated Weather Station at Falcon Lake, just south of the Zapata/Starr County line, dipped to 25 degrees; temperatures reached freezing as early as midnight.
