…. Weather Pattern Shifts with Rain Chances Decreased A Bit over Coming Days ….
…. Afternoon High Temperatures Will Continue Slightly Above Seasonal Averages ….
On this Wednesday… a surface low pressure area is over southern Oklahoma southwestward into southwest Texas. A weakening stationary front extends westward from southern Georgia into central Louisiana. As a result of this pressure pattern, a south southeasterly surface wind is continuing across our area.
In the upper levels of the atmosphere, a trough.. or line.. of upper air low pressure is located over the eastern seaboard of the USA with another one over the northwestern USA and the intermountain region. A small upper air low pressure disturbance is located over northwest Texas. As a result of the upper air wind flow, the upper level winds are light and variable over our area.
More changes today as models and guidance are now swinging back toward a much drier pattern. The focus for rain showers and thunderstorms has shifted more to the north of the local area with rain chances locally considerably diminished over the next few days.
As a result, I’ll include only isolated to widely scattered rain showers and thunderstorms in the forecast with a little more sunshine and a little warmer temperatures over the next few days.
By late Friday through next weekend, initial guidance continues to suggest a dry and stable weather pattern as upper high pressure generally dominates and acts like a “lid” on the atmosphere. I will continue to go for the general drier solution for the weekend but I will include isolated to widely scattered rain showers and thunderstorms for Saturday into early next week.
For Austin and south central Texas… tonight will be partly to mostly cloudy early with low clouds late with isolated to widely scattered rain showers and thunderstorms with lows in the 70s. South southeasterly wind. For tomorrow, partly to mostly cloudy with isolated to widely scattered rain showers and thunderstorm with highs in the 90. South southeasterly wind.
Have a good Wednesday night and Thursday…
