… Unsettled Weather Pattern Continuing …
… Rain Chances Tomorrow into Saturday …
On the Weather Map…
On the surface map… a dissipating stationary front extends northeastward from deep south Texas along the Texas coast into southern Louisiana. Surface high pressure is located over the St. Lawrence River Valley of the northeastern USA into eastern Canada. As a result of this surface weather pattern, our surface winds over south central Texas are northeasterly.
On the upper air map… a deepening trough, or line, of upper level low pressure is moving slowly eastward from western Canada into the Pacific northwest and intermountain west. Upper air high pressure, acting like a “lid” on the atmosphere, continues over the northwestern Mexico as well as along the mid Atlantic seaboard of the USA. As a result of this upper air weather pattern, the 30,000 foot winds over our local area are light.
What I am Seeing As I Look Ahead…
With the dissipating stationary front still sitting along the Texas coast in combination with the approaching area of disturbed weather over the western Gulf of Mexico, a moist and unstable air mass will, over the next few days, produce scattered to numerous rain shower and thunderstorm activity for south central Texas. Heavier rainfall is possible.. especially south of Austin.. and localized flooding is possible Friday into Saturday.
As the result of cloud cover and areas of precipitation, afternoon high temperatures will continue to be below seasonal averages.
I expect our air mass will become more stable once again by early into mid parts of next week with increased sunshine and lowering rain chances.
Have a good Thursday..
