AUSTIN / UNIVERSITY OF TEXAS WEATHER
SEVEN DAY WEATHER HEADLINES
AND MY 7 DAY FORECAST CONFIDENCE …

(1) Upper level high pressure, acting like a “lid” on the atmosphere, will
result in a stable dry summer weather pattern with near or slightly above seasonal average temperatures through mid week.

(2) The upper level high will weaken overhead as the center of the system shifts more north northeast of the area by late week into the weekend with a better flow of moist and more unstable air surging northwestward from the Gulf of Mexico. As a result, I am returning rain and thunderstorm chances to the forecast for this time period.

(3) The NWS/National Hurricane Center is monitoring an area of disturbed tropical weather moving westward over the eastern Caribbean Sea. By the end of the week and into the weekend, this system will be over the western Caribbean Sea with longer range guidance suggesting a more northwestward movement toward the western Gulf Of Mexico by early next week. All interests around the Gulf of Mexico should be monitoring the latest forecast information from the meteorologists at the NWS/National Hurricane Center.

NWS/Weather Prediction Center rainfall guidance, over the next seven days, is forecasting 0.10″ or less of rainfall for the IH35 corridor.

MY FORECAST CONFIDENCE OVER THE NEXT SEVEN DAYS…
High to very high forecast confidence through Saturday
Medium forecast confidence Sunday
