…. South Southeasterly Surface Winds Continue Across Texas ….
…. Late Night and Early Morning Cloudiness with an Otherwise Partly Cloudy Sky ….
On this Monday… surface high pressure is centered over the southeastern USA. A trough.. or line.. of low pressure extending southward from eastern Colorado and western Kansas into the Oklahoma and Texas panhandles and further south into southwest Texas and northern Mexico. As a result, a southerly surface wind is blowing across our area.
In the upper levels of the atmosphere, a rather benign zonal (west-to-east) upper level wind flow persists across Texas. As a result of the upper air wind flow, the upper level winds are light to moderate west southwesterly over Texas.
As a weak upper air disturbance move eastward in the upper air flow to the north of our area, we could see a few rain showers and thunderstorms to our east through tonight.
Otherwise, little change as predicted as the active jet stream pattern remains well to our north with fronts not expected to make much headway southward into Texas over the next seven days.
Late night and early morning low cloudiness will be present with some light drizzle possible along the IH35 corridor with our extensive morning low cloudiness. Otherwise expect a partly to mostly cloudy sky. The south southeasterly surface winds will continue with additional return of low level moisture through the remainder of the week into next weekend with afternoon temperatures continuing above seasonable levels.
My forecast confidence continues high to very high through the weekend into the early and mid part of next week.
For Austin and south central Texas… tonight will see a partly cloudy sky with low clouds thickening after midnight. Lows around 70. Southerly wind. For tomorrow, it’ll be partly cloudy after morning low clouds. Highs in the 80s with a southerly wind.
Have a good Monday night and Tuesday…
