… A Dry and Summer Like Weather Pattern Continues …

On the Weather Map…

On the surface map… a low pressure area is over the Texas/New Mexico state line with a stationary front extending northeastward into northwestern Oklahoma and central Kansas and northeastward from there. A dryline, a boundary between moist air mass to the east from the drier continental airmass to the west, extends from the surface low southwestward into southeastern New Mexico and far southwestern Texas. Surface high pressure is situated well to our east off the southeastern USA seaboard. As a result of this surface weather pattern, our surface winds over south central Texas are southerly.

On the upper air map… a trough, or line, of upper air low pressure extends southeastward from Hudson Bay into the southeastern USA. A trough, or line, of upper level low pressure area also extends south southwestward from northern Idaho southward to off the coast of southern California. Upper level high pressure is building northeastward from northern Mexico into the southern plains states. As a result of the upper air weather pattern, the 30,000 foot winds over our local area are northwesterly about 35 to 40 mph.

What I am Seeing As I Look Ahead…

The dry weather pattern continues with the stable summer like weather pattern to prevail through the balance of the week and continuing into the upcoming weekend.

Guidance is still suggesting that afternoon highs will rise to near 100 by the weekend as the upper level high pressure, to our southwest over northern Mexico and southwest Texas, builds northeastward into the area and establishes more of a “lid” on the atmosphere locally.

There are still some indications that a weak cold front.. with stronger northwest winds aloft.. will make it southward into central Texas by Sunday morning. With upper air high pressure increasing its hold on the area, afternoon high temperatures locally may peak in areas in advance of the front by Saturday and Sunday as the front tries to move deeper in Texas. Some marginal instability and atmospheric lift will develop Sunday afternoon south of the dissipating front; as a result, I’ll now include isolated thunderstorms primarily north of Austin with an associated lightning risk as well as a threat of very strong, potentially damaging, straightline winds.

Extended forecast guidance suggests that Sunday cold front will wash out just to our north by Sunday afternoon and then return back quickly northward as a warm front by Sunday night into Monday. Upper level high pressure will continue to dominate our weather pattern with a dry weather pattern for much of next week.

Based upon the latest NWS/Weather Prediction Center guidance, rainfall, over the next seven days, will average less than a tenth of an inch.

Have a good Friday..
