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.

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

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
