Weekly Climate Summary 09/27/2021

This week in Texas weather saw another dry week for the majority of the state. The South Plains and Gulf Coast saw the most precipitation in the state between 0.15”-0.9” for most of these regions. However, certain counties in these regions saw increased precipitation at 1.2”-1.8” such as in Brazoria County, Webb County, and Duval County. Aransas County, Calhoun County, and Refugio County saw the highest precipitation accumulation in the state at 2.1"-2.4”. For the remainder of the state, precipitation accumulation was 0.1” or less. A few pockets of precipitation around Madison County, Ellis and Hill County, and Hall County saw precipitation up to 1.2” but these counties were an anomaly as the remainder of North, Central, and West Texas were particularly dry.

This week Texas saw varying temperature departures across the state. The Gulf Coast, Piney Woods Region, western side of the Edwards Plateau, and the region southwest of Austin Texas in Travis County saw a negative temperature departure. These areas were 0-4 degrees Fahrenheit cooler than the normal. Brazoria County saw the most extreme negative departure at 6 degrees cooler. The Big Bend Region, Panhandle, the remainder of the South Plains, and Prairies and Lakes Region saw a positive temperature departure. Temperatures in these areas were 0-6 degrees Fahrenheit warmer than the normal. Furthermore, a pocket around Burleson and Washington County also had a positive departure up to 6 degrees warmer in these counties.

The negative temperature departure could be attributed to the cold front that passed through the state this week. Monday the 20th saw the introduction of the cold front to Northern Texas and the front had passed through the state by Wednesday the 22nd. This cold front brought cooler temperatures to much of the state as temperature averages were in the 70’s.
