Episode narrativeepisode_narrativeA deep trough of mid level low pressure, extending from the Upper Midwest southwest into Texas brought a period of cold rain and snow to South Texas on the 4th. When the clouds cleared at the end of an unusually cold afternoon on the 4th, Canadian high pressure overspread the region overnight on the 4th and into the 5th, bringing the coldest surface temperatures in nearly 5 years to all of Deep South Texas. ||Morning lows on the 5th dropped to the mid 20s to around 30 in all counties, with freezing or lower temperatures lasting up to 6 hours in typically colder pockets. The freeze was frosty for many critical agricultural areas of the Rio Grande Valley; temperatures hovering just below 32 combined with calm winds limited notable damage to protected crops and plants.
Event narrativeevent_narrativeDaytime temperatures held in the lower to mid 40s even as skies cleared during the late afternoon of December 4th, setting the stage for a widespread freeze overnight on the 4th into the morning of the 5th as clear skies and calm winds allowed temperatures to fall steadily from the 30s into the 20s in Jim Hogg County. By daybreak on the 5th, lows fell to the mid or upper 20s, including 26 at Jim Hogg County Airport northwest of Hebbronville and 24 at the Hebbronville Cooperative observing site. Estimated and measured duration of 32 degree or lower temperatures was 7 to 10 hours.
