Highland Lakes Chapter

Highland Lakes NPSOT Meeting: Saturday, 17 January “Spring and Early Summer Weather”

Bob Rose, the chief meteorologist for Lower Colorado River Authority (LCRA), is the speaker for the Highland Lakes Native Plant Society of Texas’ Chapter meeting on Saturday, 17 January 1:00-3:00 p.m. at the Marble Falls Library, 101 Main Street.

Bob is responsible for the daily forecast of weather conditions and temperature affecting LCRA’s power generation, electrical transmission, flood control and water supply operations. In addition to short term forecasts, he provides LCRA operation centers with long-term weather forecasts and updates on the threat of severe weather and extreme temperatures. Bob worked at TV stations in Austin and Bryan-College Station prior to coming to LCRA. He earned his B.S. in Meteorology from Texas A&M University.

Bob has served as past president of the Central Texas Chapter of the American Meteorological Society (AMS), and holds the seal of approval and the certified broadcast meteorologist award from the AMS. He is a regular contributor to the National Drought Monitor, and is also the Travis and Williamson County coordinator for CoCoRaHS, a volunteer network of rainfall observers. His daily blog, Bob’s Blog on Central Texas Weather, can be found at lcra.org.  Bob gives numerous talks about the weather to various civic and school groups around Central Texas. He enjoys traveling and has been on 17 different cruises to various parts of the world.

Bob’s presentation, “Spring and Early Summer Weather,” will provide insight into how the weather outlook affects our planting and maintenance of native plants. His presentation will address:

§  Drier than normal weather conditions look to continue into early spring. A change to a wetter pattern expected mid and late spring.

§  Warmer than normal temperatures are expected to start early and continue through spring

§  Odds are increasing for the development of an El Nino this summer

Chapter business occurs during the first 30 minutes of the meeting, followed by Bob’s presentation.

About the Region

2026 Fall Symposium Logo

This low-elevations region of Texas extends inland from the barrier islands, about 60 or so miles, and stretches from Brownsville to Louisiana. In total, it covers about 9.5 million acres, with a high point of 150 feet in elevation. More than 1000 species of plants can be found in this region. On the southern end, species more common in Mexico (such as Sabal mexicana) and Central America occur.

The barrier islands provide us with dune systems, and clay flats to the inland side, which have species found in these areas alone. Many plants here, such as Ipomoea pes-caprae (beach morning glory), can be found throughout tropical regions of the globe. I’ve encountered the same species on the beaches of Guam.

Once inland, vast marshes and wet prairies occur. Occasionally, oak (Quercus fusiformis) groves can be found. Common grasses include species of Bothriochloa, Paspalum, and Sporobolus; eastern gamagrass (Tripsacum dactyloides); and switchgrass (Panicum species). Many rivers and creeks cut through the Gulf Prairies, and along these riparian areas various species of trees, Sabal minor, and other plants adapted to clay soils can be found. Due to overgrazing, farming, and fire suppression, woody species such as mesquite (Prosopis glandulosa) and huisache (Acacia farnesiana), and invasive species such as chinaberry (Melia azedarach), Brazilian pepper (Schinus terebinthifolius), and Chinese tallow (Sapium sebiferum) have increased and displaced our native flora.
