…. A Dry Weather Pattern ….
…. A Tropical Air Mass Continues Across the Area ….

On this Tuesday… a surface high pressure area is located over the southeastern USA  and the lower Mississippi Valley. A weak trough.. or line.. of low pressure extends southward from Eastern Colorado southward into eastern New Mexico. Another surface high pressure area is over western Colorado and northwestern New Mexico. As a result of this surface pattern, a southerly 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 broadly over the US central plains east southeastward into  the Mississippi Valley. As a result of the upper air wind flow, the upper level winds are light to moderate southeasterly over our area.

A moist tropical air mass continues across the area and, for the most part, the large upper level high pressure area to the north is increasing its influence on our area weather by keeping the “lid” on the atmosphere.

It looks like a dry forecast for the next seven days. Afternoon high temperatures will continue to be at or above seasonal averages through the seven day forecast period.

For Austin and south central Texas… tonight will see a partly cloudy sky with lows in the 70s. Southerly wind. For tomorrow, morning low clouds will give way to a mostly sunny sky with highs in the 90s with a southerly wind.

Have a good Tuesday night and Wednesday…
