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 coastal Cameron County, air temperatures likely fell to 32F by approximately 11 PM on February 4th (pockets fell to 32F as early as 915 PM), and continued falling into the upper 20s to around 30F, 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 - occurred in a few pockets north and east of County Road 106, generally near the Laguna Atascosa National Wildife Refuge, where minimum temperature fell to 24 degrees with hard freeze conditions lasting up to 6 hours. ||The long duration of cold was aided by highs on the 4th, which only reached 40, giving a head start to rapid cooling in light winds and starry skies. Other low temperatures included Bayview/Cameron County Airport (29 degrees; 7 hours of freezing) and South Padre Island heliport (29 degrees; 9 hours of freezing temperatures).
