|Episode Narrative||A blast of very cold Canadian air came sweeping down the Great Plains, migrating from the Yukon and Northwest Territories through Saskatchewan and Alberta Provinces, starting on January 6th. The high pressure cell, sourced near the Arctic Circle, brought sharply falling temperatures on January 7th, which would fall just below freezing across the Rio Grande Plains by daybreak of January 8th, and near freezing by mid to late morning on the 8th before struggling to rise into the mid 30s to near 40 toward evening under slate gray clouds, accompanied by a little sleet and rain mixed across the Lower Rio Grande Valley around midday.
Evening clouds on the 8th allowed a gradual temperature fall, but as skies cleared toward midnight, temperatures began a steady drop beginning across the Rio Grande Plains before midnight, spreading southeast and clearing the coast a couple of hours after midnight. By daybreak, all of Deep South Texas, save for the immediate coast and urban/developed locations, sustained hard freeze conditions.
Minimum temperatures ranged from the upper teens across the ranchlands of the Upper Rio Grande Valley of Zapata and Starr County stretching east through much of Jim Hogg, Brooks, northern Hidalgo, and into western Kenedy County. Elsewhere, lows ranged through the low and mid 20s, except mid and upper 20s in the urban pockets of McAllen/Pharr/Edinburg and toward the immediate coast from Brownsville to South Padre Island, who even touched 32.
The freeze on the 9th probably caused the most damage for the entire period, as insulating frost was confined to low lying, wind protected areas. Light winds and low humidity in most areas kept frost from developing.
|Event Narrative||Temperatures fell below freezing shortly before midnight on the 8th, and ultimately fell into the lower and mid 20s by daybreak on the 9th across much of Brooks County. Freezing temperatures lasted up to 10 hours near Falfurrias and in locally colder pockets elsewhere, with a hard freeze, defined as temperatures below 28 degrees, lasting between 4 and 8 hours, with the longest duration in aforementioned colder pockets. The cooperative station at the Hollywood Hunting Camp near Falfurrias dipped to 20 degrees; Brooks County Airport dropped to 24.
Early planting of rangeland known as coastal grasses was severely damaged from the Freezes on the 9th and 10th. Damage to these grasses, as well as any local tender vegetation, was unknown as of this writing.
