…. Afternoon Highs Down a Few Degrees over the Next Seven Days ….
…. Upper Level High Pressure Lid Weakens / Moves Eastward a Bit ….
…. No Rain Chances in my Forecast over the Next Seven Days ….

On this Wednesday… a surface high pressure area is located over the Ohio Valley region and to the west over the four corners region. A trough.. or line.. of surface low pressure extends southward from eastern Colorado into eastern New 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 area of upper air high pressure is located over the central and southern plains. As a result of the upper air wind flow, the upper level winds are light and variable over our area.

Upper level high pressure is still situated overhead although the strongest part of the “heat dome” is shifting eastward a bit. As the upper level high weakens over the coming days, we’ll see a few more clouds and a slight drop in the average afternoon high temperatures.

The dry and stable weather pattern will continue, in general, overhead through the next seven days. Through the seven day period, I’m not excited about any rain chances for the area.

There is some indication that the upper level high will rebuild and strengthen overhead by next week so I’ll bring up daytime high temperatures again by the middle part of next week.

For Austin and south central Texas… tonight will see a mostly clear sky with lows in the 70s. South southeasterly wind. For tomorrow, mostly sunny with highs around 100. Southerly wind.

Have a good Wednesday night and Thursday…
