Episode narrativeepisode_narrativeA 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 narrativeevent_narrativeTemperatures fell below freezing by 1 AM on the 9th, bottoming out in the upper 20s to around 30 by daybreak across Coastal Cameron County. Lows ranged from 28 at Laguna Atascosa National Wildlife Refuge to 32 on South Padre Island. Freezing temperatures likely lasted up to 7 and one half hours. A few pockets may have received an hour or two of a hard freeze, defined as temperatures below 28 degrees.||Crop damage was unknown as of this writing. Information from the Farm Services Agency of Cameron County suggested only minor damage to citrus plants, with most fruit and trees surviving the freeze. Tropical tender vegetation did not fare as well, but significant damage was not reported near the coast.
