… Watching Isaac But Still Little Effect Expected Locally on Current Forecast Track …
… A Dry Seven Day Forecast …

On this Wednesday… surface high pressure is over the eastern USA and over the four corners region.  Hurricane Isaac is located just west of the New Orleans metro area. As a result of this surface pattern, a northerly 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 northwest of the local area over the southeastern Rockies and southwestern plains.  As a result of the upper air wind flow, the upper level winds are light northeasterly over our area.

Tropical cyclone Isaac continues to move northwestward. The current National Hurricane Center track forecast suggests a continued northwestward movement. With this movement, I expect little effect locally other than the northerly wind that we’re currently seeing.

A dry and stable weather pattern is expected to continue across the area; I do not expect any frontal passages/air mass changes. Upper level high pressure, acting like a “lid” on the atmosphere, will build back overhead and will result in sinking air in the atmosphere, so no rain chances through the upcoming long Labor Day weekend.

Temperatures should continue to be above seasonal averages.

For Austin and south central Texas… tonight will see a mostly clear sky with lows in the 70s with a northerly wind 5 to 12 mph. For tomorrow, it’ll be mostly sunny with highs in the 90s with a northerly wind 8 to 15 mph.

Have a good Wednesday night and Thursday…
