…. A More Stable Air Mass ….
…. Lots of Sunshine with Warmer Temperatures ….
On this Tuesday morning…. an area of high pressure continues over the Gulf of Mexico. A trough.. or line.. of low pressure extends southwestward from eastern Colorado and western Kansas into northwest Texas and eastern 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 USA.. northwestern Mexico and adjacent areas of the Pacific Ocean. A trough.. or line.. of upper air low pressure is deepening slowly over the eastern quarter 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 continue to be generally variable at less than 15 mph.
A stable atmosphere prevails over the area as upper level high pressure strengthens a little. This pattern will continue through the remainder of the week and through the weekend into early next week as an even 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.
Other than a better organized area of disturbed weather off the west coast of Africa.. there are no other tropical threats at this time according to the forecasters at the NWS/National Hurricane Center.
Have a good Tuesday…
