Episode narrativeepisode_narrativeA section of modified arctic high pressure settled over Deep South Texas and the Rio Grande Valley late on February 4th into early February 5th, bringing clear skies, nearly calm winds, and the coldest air temperatures of the three day period to most areas. ||After an ice storm departed all areas by midday on the 4th, sunshine returned, bringing temperatures above freezing but only into the 40s, except upper 30s along the coast. With low relative humidity, the stage was set for rapid temperature falls during the evening of the 4th; before midnight, most locations away from the coast (where some wind continued) fell below 32F and would continue dropping steadily. By daybreak on the 5th, hard freezes (temperatures below 28 for several hours) covered rural areas north and west of the Lower Rio Grande Valley; sheltered pockets fell into the teens. ||Readings quickly rose above freezing by mid morning of the 5th, ending the freeze event - until the next one arrived just five days later.
Event narrativeevent_narrativeFor most of Willacy County, air temperatures fell to 32F by approximately 11 PM (sheltered locations likely fell to 32F by 8 PM), and continued falling into the mid and upper 20s, on average, before sunrise, with these temperatures continuing until an hour or so after sunrise before rapidly rising into the 50s by noon. A hard freeze - temperatures below 28 degrees for 2 or more hours - was common for most of the largely rural county. Coldest temperatures in the mid 20s were most likely west of Raymondville, interpolated from 24 degrees at San Manuel (less than 10 miles west of the border).||Other specific temperatures included: 27 degrees at the Port Mansfield and Raymondville cooperative observing stations, and 24 degrees at Laguna Atascosa NWR (9 miles south of the county line).||Additional light to moderate damage to cold sensitive crops likely occurred with the cold temperatures on the 5th. See the report for the long duration freeze from the 3rd through the 4th for details.
