.. Little Change ..
.. A Dry and Stable Weather Pattern Continues ..
On this Monday…. a weakening cold front extends westward across southern Missouri then along and just north of the Kansas/Oklahoma border into the northwestern part of the Texas panhandle. A trough.. or line.. of low pressure extends south southwestward from western Texas and eastern New Mexico southwestward into far southwest Texas. Surface high pressure is over the eastern Gulf of Mexico and the southeastern USA and eastward across the western Atlantic Ocean. As a result of this surface weather pattern, our local surface winds are southerly.
In the upper levels of the atmosphere.. an upper level high pressure area.. acting like a “lid” on the atmosphere.. is centered over the our area of Texas. An upper level low pressure trough extends southwestward over California. An otherwise rather zonal (west-to-east) upper level wind pattern across the USA. As a result, our upper air winds at about 18,500 feet, are light and variable.
A typical summer weather pattern continues with a moist and tropical air mass holding across the area.
More of the same is expected through the seven day forecast period. Upper level high pressure, acting like a “lid” on the atmosphere, should keep us dry with afternoon high temperatures near or even slightly above seasonal averages. While a few 100 degree readings are possible over areas over the hill country west through southwest of the Austin area.. most afternoon high temperatures will remain in the mid and upper 90 degree range through the balance of my seven day forecast period.
I do not expect any precipitation through the seven day forecast period.
Looking beyond, the NWS Climate Prediction Center’s 8 to 14 day outlook.. pretty much through the remainder of the month and into early August.. strongly suggests a seasonally warm and dryer than average weather pattern continuing.
Have a good Monday….
