.. Drier with Plenty of Sun Through the Weekend ..
.. An Unsettled Weather Pattern Developing with Rain Chances Next Week …

On this Friday… a surface low pressure area is over central Arkansas with a cold front extending southwestward into east Texas to onshore along the Texas coast to near Eagle Pass then into northern Mexico and far southwest Texas. Surface high pressure is located behind the front over eastern Colorado and western Kansas. As a result of this surface weather pattern, our surface winds across south central Texas are north northwesterly.

In the upper levels of the atmosphere, a strong northeastward moving upper air low pressure disturbance is over Arkansas. Another eastward moving upper air low pressure disturbance is located along the Oregon and Washington coasts. As a result of this upper air weather pattern, the 30,000 foot winds over south central Texas are west northwesterly 50 to 60 mph.

After the late afternoon thunderstorms (with some hail in northern and western parts of the Austin/IH35 corridor area) yesterday and isolated thunderstorms in the eastern areas after midnight as the cold front moved through, a drier and more stable weather pattern will prevail into the weekend with abundant sunshine. Nighttime low temperatures will be a bit cooler due to the dryness of the air.

As surface high pressure, in the wake of the front, moves east of the area by early Sunday, southerly surface winds will pick up over the area. Low level moisture will increase over the area with late night and early morning low clouds returning as early as Monday and Tuesday mornings.

By the middle into latter parts of next week, an approaching upper air low pressure and associated cold front will move slowly eastward through the western and southwestern USA parts of next week. I’ll introduce rain chances beginning Wednesday with rain and thunderstorm chances increasing even more by Thursday into Friday. Early guidance, from some of the computer models, suggests the possibility of severe thunderstorms and heavier rain for the latter part of next week for parts of Texas.

Have a good Friday….
