Mostly Dry and Stable Weather Pattern…
Stronger Cold Front Due Early Saturday Morning With Weekend Cool Down …
On this Tuesday… a high pressure area is located over the plains and Rockies as it moves southeastward into Texas. A low pressure area is over Kentucky with a front extending into northwest Florida and into the Gulf of Mexico. As a result of this surface pattern, a northerly surface wind prevails across our area.
In the upper levels of the atmosphere, the deep trough of low pressure extends south southwestward from the Great Lakes into east Texas. As a result of this upper air wind flow, our upper level winds are moderate to strong northwesterly.
A mostly dry and stable weather prevails across our area even though southeastward moving upper air disturbances.. in the upper flow on the back side of the upper air trough.. will keep a slim chance of rain showers and thunderstorms (some of which could produce some stronger wind gusts and smaller hail) until about midnight.
Southerly surface winds will return by tomorrow into tomorrow night as the surface high pressure area moves east of the area and our upper levels become more zonal
(west-to-east) across the area.
By Friday into the weekend, a passing upper level disturbance will help a cold front.. the strongest of the fall season so far.. to move across the area. This front will usher in much cooler air even though clouds may linger back behind the front into Saturday night.
A dry.. cooler than average weather pattern will prevail for Sunday into early next week.
For Austin and south central Texas… tonight will see a partly cloudy sky with isolated thunderstorms until midnight. Low around 60 with a light east southeasterly wind. For tomorrow, it’ll be mostly sunny with highs in the 80s with a south southeasterly wind returning.
Have a good Tuesday night and Wednesday…
