Episode Narrative A 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 Narrative Temperatures dipped to 32F as early as 8 PM on February 4th, and would continue through 830 AM on the 5th before quickly rising into the 40s and 50s before noon. A hard freeze - temperatures below 28F for 2 hours or more - was widespread in the largely rural county. The low at Brooks County Airport (southeast of Falfurrias) dipped to 27 degrees, which held fo 2.5 hours. The cooperative observer at the Hollywood Hunting Camp (west of Falfurrias) recorded a low of 21 degrees. Interpolating between observing locations at Linn/San Manuel suggested between 12 and 13 hours of freezing temperatures during the event in much of the county.
