A Passing Upper Air Low Pressure Disturbance into the Afternoon ….
Dry and Stable Weather Pattern for the Next Seven Days ….
On this Friday morning…. a unseasonably strong cold front is along a line from eastern Tennessee southwestward through the New Orleans area into the extreme northwestern Gulf of Mexico to south of Corpus Christi into northeastern Mexico and into the Texas Big Bend Country. Surface high pressure is settling southward into Texas from the north in the wake of the cold front. Given this surface pressure pattern, surface winds are north northeasterly across our area.
In the upper levels of the atmosphere… a broad upper level low pressure trough.. or line of low pressure.. is located over the eastern 1/2 of the USA. As a result of this upper air pattern, winds over south central Texas and the Austin metro area about 18,000 feet above the ground are northwesterly 20 to 30 mph.
The cold front, over the northwest Gulf of Mexico, is washing out as it moves southeastward and high pressure settles southward into our area in the wake of the front that moved through our area around 6pm yesterday.
An upper air low pressure disturbance is tracking southeastward over the area with some clouds and rain showers and thunderstorms to our distant west.. but these should remain well south and southwest of the local area. The disturbance will move through the area by early to mid afternoon.
The surface high pressure, in the wake of the front, will move east of the area by later today into tonight with surface winds returning back south southeasterly by tomorrow. Overall, it looks dry and summer like for through the weekend and into the middle part of next week as the atmosphere becomes more stable once again. Temperatures will be at or above seasonal levels for the weekend through next week with no rain mentioned in the forecast.
Have a good Friday night and Saturday…
