… Unsettled Weather Pattern Continuing …
… Rain Chances Continue into the Weekend …
On the Weather Map…
On the surface map… the stationary front has generally washed out along the Texas coast. Surface high pressure is located over the eastern Great Lakes with a trough, or line, of low pressure over the western Texas panhandle and eastern New Mexico. 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 southerly about 20 mph.
What I am Seeing As I Look Ahead…
With the dissipating stationary front still sitting along the Texas coast in combination with the area of disturbed weather over the western Gulf of Mexico moving ashore into south Texas, 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 Friday..
