…. A Dry Summer Weather Pattern Through the Labor Day Weekend ….
On this Wednesday morning…. surface high pressure continues over the southeastern USA.. northeastern Gulf of Mexico as well as the western Atlantic Ocean. Another high pressure area is to our distant west over the four corners region. A low pressure area is over southeastern Colorado with a trough.. or line.. of low pressure extending southward into eastern New Mexico and far west Texas. As a result of this surface weather pattern, surface winds are south southeasterly over our area.
In the upper levels of the atmosphere… a strong upper level high pressure area continues over Missouri and the middle Mississippi Valley. Being on the south side of the upper air high, winds over south central Texas and the Austin metro area about 18,000 feet above the ground are easterly 10 to 20 mph.
Through the remainder of the week and into the upcoming Labor Day weekend, I expect that the upper level high pressure area.. to our north.. will continue settle back south southwestward to become more overhead of our area. As this occurs, our rain chances from the last few days drop from the forecast. In addition, given the on-going drought conditions, afternoon high temperatures will rise once again with near triple digit temperatures possible once again.
The upper high pressure area may settle more west of our area by Sunday and Monday; even so, limited atmospheric moisture and limited atmospheric instability will keep rain from our forecast.
According to meteorologists at the NWS/National Hurricane Center, there are no systems in the Atlantic Basin (Atlantic Ocean, Gulf of Mexico and the Caribbean Sea) that threaten development over the next five days.
Regarding my forecast, my local forecast confidence: Very high forecast confidence through the next seven day period.
Have a good Wednesday…
