||A fairly vigorous cool front swept through Deep South Texas early on December 12th, followed by strong high pressure with Canadian roots but not truly frigid air to arrive later on the 12th into the 13th. Clear and relatively calm conditions overnight allowed temperatures to fall near or just below freezing in rural Deep South Texas. In locations where the temperature remained just above freezing, dew points remained in the teens, and prolonged low wet bulb temperatures in the mid 20s likely created a proxy freeze for tender vegetation in neighborhoods and towns.
The very dry, cold morning further cured fine and medium fuels (grasses and brush); the freeze was the fourth of the season in a little more than two weeks.
||The cooperative observer at the Hollywood Hunting Camp just west of Falfurrias recorded a low of 27 degrees. Proxy locations in Kenedy County (Lebh Shomea House of Prayer, 30) and northern Hidalgo County (Lower Rio Grande Valley National Wildlife Refuge near San Manuel, 29, for three hours) support several hours of freezing temperatures across the Brooks County brush country. In addition, dew points in the upper teens to lower 20s supported wet bulb readings in the mid to upper 20s. Prolonged low wet bulb temperatures are known to create a proxy freeze to unprotected tender vegetation.
