… Lots of Sunshine over the Next Seven Days ….
… Very Limited Rain Chances …
… Near to Slightly Above Average Temperatures Expected to Continue ….
On this Wednesday… surface high pressure is over Arkansas with a trough.. or line.. of low pressure southward from southeastern Colorado into New Mexico. As a result of this surface pattern, a easterly 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 over the Rockies and the southwestern plains states with a deeper trough.. or line.. of upper level low pressure extends southward from the Great Lakes states southward over the eastern half of the USA. As a result of the upper air wind flow, the upper level winds are light to moderate northwesterly over our area.
A mostly dry and stable weather pattern is expected to continue across the area over the next seven days with no frontal passages expected. As we’ve seen in the last few days, there has been a little more cloud cover and even a few rain showers due to the northwesterly wind aloft bringing upper air disturbances through the area. With the upper high moving eastward a little, I think that the rain chances locally are now reduced. Nevertheless, I’ll continue to watch for this possibility in the days ahead.
Temperatures should continue to be near or even slightly above seasonal averages.
For Austin and south central Texas… tonight will see a partly cloudy sky with lows around 70 degrees with an east southeasterly wind. For tomorrow, it’ll be partly cloudy with highs in the 90s with a southeasterly wind.
Have a good Wednesday night and Thursday…
