A Dry and Stable Weather Pattern Continues…
Stronger Cold Front Due Early Saturday Morning With Weekend Cool Down …
Clouds Linger Behind the Cold Front with a Few Sprinkles …

On this Wednesday… a high pressure area is located over the lower Mississippi Valley and over the southeast. A trough of low pressure area extends southward from eastern Colorado into eastern New Mexico and west Texas. As a result of this surface pattern, a southerly surface wind has returned across our area.

In the upper levels of the atmosphere, the deep trough of low pressure extends south southwestward from the Great Lakes into the lower Mississippi Valley. As a result of this upper air wind flow, our upper level winds are moderate to strong northwesterly.

A dry and stable weather prevails across our area. Southerly surface winds have returned as the surface high pressure area continues to move of the area and our upper levels become more zonal (west-to-east) across the area.

By Friday into the weekend, 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 with even a few sprinkles of very light rain late Saturday into Saturday night. Clouds will break by late Sunday into early next week.

A much cooler than average weather pattern will prevail for the weekend into early next week.

For Austin and south central Texas… tonight will see a few clouds with lows in the 60s with a southerly wind. For tomorrow, it’ll be mostly sunny with highs will approach 90 with a southerly wind.

Have a good Tuesday night and Wednesday…
