… Lots of Sunshine over the Next Seven Days ….
… A Mostly Dry Weather Pattern for South Central Texas ….
… Near to Slightly Above Average Temperatures Expected to Continue ….
On this Monday… a weakening stationary front extends from Alabama and Mississippi west southwestward into east Texas. A surface trough.. or a line.. of low pressure extends southward from a surface low over southeastern Colorado into far west Texas and eastern New Mexico. Surface high pressure is over Kansas. As a result of this surface pattern, a northeasterly surface wind is prevailing across our area.
In the upper levels of the atmosphere, a upper high pressure ridge, acting like a lid on the atmosphere, is over the western United States with a deeper trough.. or line.. of upper level low pressure extends southward from the Great Lakes states southward over the eastern half of the USA. As a result of the upper air wind flow, the upper level winds are light to moderate northwesterly over our area.
A mostly dry and stable weather pattern is occurring and is expected to continue across the area over the next seven days with no frontal passages expected.
I will watch a weak area of low pressure just off of the eastern coast of Mexico (a few hundred miles south of Brownsville). At this point, this system is expected to move into Mexico and dissipate.
In the northwesterly wind aloft, I will continue to watch for weak disturbances moving along in that northwest-to-southeast upper air flow. These disturbances can cause a few thunderstorms but, right now, I just don’t see much of a chance locally.
Temperatures should continue to be near or even slightly above seasonal averages.
For Austin and south central Texas… tonight will see a clear sky with lows around 70 degrees with an northeasterly wind. For tomorrow, it’ll be mostly sunny with highs in the 90s with a east southeasterly wind.
Have a good Monday night and Tuesday…
