…. A Stable Upper Level High Pressure Continues over the Area ….
…. Above Average High Temperatures Expected to Continue ….
…. A Warm and Humid Tropical Air Mass Remains in Place Over the Area ….
On this Tuesday… a surface high pressure area is located over the southeastern USA and to the west over the southwestern states. A trough.. or line.. of surface low pressure extends southward from western Colorado into western New Mexico and northern Mexico. As a result of this pressure pattern, a south southeasterly surface wind is prevailing across our area.
In the upper levels of the atmosphere, the upper high pressure ridge, acting like a lid on the atmosphere, continues across our area. As a result of the upper air wind flow, the upper level winds are light and variable over our area.
The upper level high is rebuilding over the area, especially north of the area, and this will resulting in a stable weather pattern across south central Texas. Over the coming days, we’ll see a little more sunshine along with the above average afternoon high temperatures.
This warm and humid tropical weather pattern will continue through the week and into next weekend. Late night and early morning low clouds will prevail over the coming days.
There is some indication of a slightly more unstable air mass along with the a little more influence off the Gulf of Mexico by Sunday into Monday. At this point, with the guidance still showing only a very slight chance of rain, I will hold off on mentioning rain chances in my forecast until I have a little higher confidence.
For Austin and south central Texas… tonight will be partly cloudy early with low clouds late with lows in the 70s. South southeasterly wind. For tomorrow, morning low clouds will give way to a partly cloudy sky with highs in the 90s. Southerly wind.
Have a good Tuesday night and Wednesday…
