…. A More Stable Air Mass Taking Hold ….
…. Slim Rain Chances Today into Early Tonight ….
…. Increased Sunshine with Warmer Temperatures ….

On this Monday morning…. an area of high pressure continues over the eastern Gulf of Mexico. A trough.. or line.. of low pressure extends southwestward from eastern Colorado and western Kansas into New Mexico. As a result, surface winds are southerly across our local area.

In the upper levels of the atmosphere… an upper air low pressure area is over southwestern Texas and northern Mexico with another one over the Pacific Ocean southwest of southern California. A trough.. or line.. of upper air low pressure is deepening slowly over the northeastern third of the country. 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 generally variable at less than 15 mph.

A more stable atmosphere prevails over the area as upper level high pressure strengthens a little. I will still keep an isolated rain shower and/or thunderstorm in our forecast today into this evening given the daytime heating combined with available low level moisture. The chance of rain, however, at any given location, is very slim so the chance of any given location seeing rain is very slim indeed.

Beyond today and continuing through much of the remainder of the new week and even into next weekend, a much more pronounced area of upper air high pressure will become established overhead.. acting like a “lid” on the atmosphere.. and will result in a dry and stable weather pattern with no mention of rain in my forecast.

There are no tropical threats at this time according to the forecasters at the NWS/National Hurricane Center.

Have a good Monday…
