||Arctic air continued plunging through Deep South Texas on February 3rd and 4th, returning freezing temperatures to all areas during the late evening of the 2nd or just after midnight on the 3rd. A weak upper level disturbance combined with just enough low level moisture to develop a mist of freezing drizzle and light freezing rain soon after sunrise on the 3rd across the Lower Valley, spreading west and north through the day. The precipitation combined with gusty north winds to lock down temperatures at or below 32 degrees for more than 30 hours in all areas.
Overnight on the 3rd and into the 4th, temperatures remained steady from the Lower Rio Grande Valley to the King Ranch, but skies cleared before daybreak farther west, allowing temperatures to bottom out in the lower to mid 20s - a hard freeze. The combination of gusty north winds 20 to 25 mph mainly east of highway 281 held wind chill temperatures near or below 20 for much of the day on the 3rd, making it the coldest feeling day in more than two decades.
||Air temperatures fell back to 32 degrees just after midnight on February 3rd, and would not recover above 32 until just before noon on February 4th - a total of 33 hours at or below 32 degrees. The Remote Automated Observing site at San Manuel, about 10 miles south of the county line, recorded nearly 35 hours. Low temperatures at Falfurrias were in the upper 20s on the 3rd and again on the 4th. A hard freeze - temperatures below 28 degrees for 2 hours or more - was recorded during the early morning hours on the 4th.
