… A Stable Weather Pattern Continues …
… Rain Shower and Thunderstorm Activity Increases Late Week into the Weekend …
On the Weather Map…
On the surface map… weak high pressure continues over the Mississippi River Valley southward into the Lower Mississippi Valley and Texas. A trough, or line, of surface low pressure extends from eastern Colorado southward into New Mexico. As a result of this surface weather pattern, our surface winds over south central Texas are light and variable or light south southeasterly.
On the upper air map… a trough, or line, of upper level low pressure is moving slowly eastward from western Canada into the Pacific northwest and inter mountain west. Upper air high pressure, acting like a “lid” on the atmosphere, continues over the northwestern Mexico into north Texas and Oklahoma. As a result of this upper air weather pattern, the 30,000 foot winds over our local area are east northeasterly 20 to 25 mph.
What I am Seeing As I Look Ahead…
A dry and stable late summer weather pattern is prevailing across Texas; as a result, we’ll see increased sunshine and warmer temperatures through tomorrow.
By late week and through the weekend, another area of clouds and rain showers and thunderstorms, associated with an upper level low pressure disturbance, will move northwestward from the Gulf of Mexico and into south Texas. We’ll see increased clouds as well as a better chance of rain showers and thunderstorms. NWS/Weather Prediction Center estimates that we’ll see 1/2 to 1 inch of rain during the period.
Upper level high pressure.. acting like a “lid” on the atmosphere.. looks to rebuild a bit over Texas by early next week with decreased rain chances and a bit more sunshine.
Have a good Tuesday..
