TK’s Weather Update for Thursday / 13 July 2017….

.. A Stable Summer Weather Pattern Continuing ..
.. Rain Chances Still Show Up Over the Weekend ..

On the Weather Map…
Surface map… surface high pressure is to the east of the area over the southeastern USA and the northern Gulf of Mexico with a weakening cold front moving southward from central Missouri through central Kansas southwestward into a surface low over the Oklahoma panhandle then across the Texas panhandle into northern New Mexico then northward as a stationary front into western Colorado. As a result of this surface weather pattern, our surface winds across south central Texas are southerly.

Upper air map… a zonal (west-to-east) upper air wind pattern continues over the USA with passing upper level low pressure disturbances remaining well north of the USA/Canada border. An upper level high pressure area.. acting like a lid on the atmosphere.. is centered over the intermountain west and the Rockies. There is a weak upper level low pressure area over the Rio Grande River west northwest of Del Rio with several other upper air disturbances over the lower Mississippi Valley and the southeastern USA. As a result of this upper air weather pattern, the 30,000 foot winds over south central Texas are southerly 5 to 15 mph.

What I am Seeing As I Look Ahead…
There will continue to be little change in the overall stable weather pattern for south central Texas and the Austin metro area over the next few days. While a few towering clouds are possible primarily in areas along and east of the IH35 corridor and along and south of the IH10 corridor today into this evening and over the next day or so, I do not expect any precipitation locally.

By the weekend into next week, longer range computer model and manual forecast guidance continues to suggest that the upper level high pressure will weaken a bit and settle back north northwestward into the northern Rockies and plains states. This will allow for better moisture flow off of the Gulf of Mexico as a weakening cold front settles southward into Texas and the lower Mississippi Valley. As a result, I think we’ll see more cloud cover and a little better rain chances beginning Saturday and continuing Sunday and into the new week. At this time, the latest NWS/Weather Prediction Center guidance suggest rainfall, on average, of 1/4 to 1/2 inch locally for the Saturday through Tuesday time period.

Have a good Thursday….
