…. A Dry and Stable Weather Pattern Continues ….
…. Daytime High Temperatures Warming a Bit ….

On this Tuesday morning…. a trough.. or line.. of surface low pressure extends southward from southeastern Colorado and far west Texas and eastern New Mexico. Surface high pressure is to our northeast over eastern Arkansas and northern Mississippi. As a result of this surface weather pattern, our local surface winds are light.

In the upper levels of the atmosphere… an area of upper level high pressure is sandwiched over the southern Rockies and the southern plains between troughs of low pressure one that is situated over the eastern third of the USA and the other one over Nevada and the western third of the country. As a result of this pattern, the upper level winds over south central Texas and the Austin metro area, about 18,000 feet above the ground, are relatively light.

Surface high pressure continues to the distant northeast of the area; it is moving eastward as lower pressure continues to develops to our west. This will result in a return south southeasterly surface wind flow over the next 12 hours or so. Even with the return south southeasterly wind flow, I expect the mostly stable weather pattern to continue across the area.

As low level moisture increases a bit, we’ll see a bit of an increase in clouds over the coming days. At the same time, the upper level high pressure area to our west will intensify its hold on Texas with daytime high temperatures on the way up as well.

Overall, over the next seven days, temperatures will be near to slightly above average with no precipitation expected.

Regarding my forecast, my local forecast confidence: My forecast confidence is very high over the next seven days.

Have a good Tuesday….
