||A second modified arctic high pressure cell, coming just a week after a more significant and prolonged freeze and ice storm, initially brought afternoon wind chill temperatures down into the mid 20s to mid 30s on February 9th under steel gray skies. By sunset, skies cleared gradually from west to east; with starting temperatures in the low 40s, the stage was set for another widespread freeze.
By daybreak on February 10th, lows ranged from the upper 20s to lower 30s in most areas under clear skies and a range of north winds. Rural locations north and west of the Lower Valley saw winds drop generally below 10 mph, but still produce wind chill close to 20 degrees. Across the Lower Valley toward the coast, the combination of freezing temperatures with sustained 15 to 25 mph wind brought wind chill values to 20F as well.
||Temperatures across Brooks County fell to the freezing point shortly after 3 AM on the 10th, then continued in the upper 20s to around 32 degrees through 9 AM before rising through the 30s and 40s by noon. The cooperative observer in Sarita recorded a low of 28 degrees; the Remote Automated Weather Station at Linn/San Manuel National Wildlife Refuge (northern Hidalgo County) dipped to 29, with freezing temperatures lasting six hours.
