…. Upper Level High Pressure Strengthens Again ….
…. A Warm and Humid Tropical Air Mass Remains in Place Over the Area ….
On this Monday… 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 air low pressure area has settled further westward into northern Mexico and the southwestern USA with a strengthening of the upper high pressure ridge across our local area. As a result of the upper air wind flow, the upper level winds are still light and easterly over our area.
The upper level high is rebuilding over the area, especially north of the area, and this will result in decreasing the clouds a bit.. reducing the chance of rain and bringing up daytime high temperatures again.
This warm and humid tropical weather pattern will continue through the week and into next weekend with any rain chances decreasing after today. Late night and early morning low clouds will prevail over the coming days.
For Austin and south central Texas… tonight will see an isolated evening thunderstorm otherwise it’ll be partly cloudy 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. South southeasterly wind.
Have a good Monday night and Tuesday…
