…. Sunshine and Much Cooler Temperatures For Now ….
…. A Warming Trend with Clouds Increasing Again Late Week ….
On this Tuesday morning…. surface high pressure /1027mb/ is centered over north and west Texas over the Abilene area. The cold front.. that passed our area early yesterday morning.. extends from Georgia and Alabama southward deep into the central Gulf of Mexico then into Mexico well south of Brownsville. As a result of this surface weather pattern, our local surface winds are northerly.
In the upper levels of the atmosphere… a deep trough.. or line.. of upper level low pressure extends southward from the Great Lakes into the Gulf of Mexico off the upper Texas and Louisiana coasts, As a result of this upper air wind pattern, the upper level winds over south central Texas and the Austin metro area about 18,000 feet above the ground are northwesterly at 55 to 65 mph.
In the wake of a cold front that moved through the Austin area yesterday.. clear skies.. drier and unseasonably cool air continues to settle southeastward into the area. Another chilly night is ahead with overnight low temperatures near the freezing mark in typically cooler outlying and low lying areas away from the metro Austin area again tonight.
As the surface high pressure moves east of the area by tonight into early Wednesday, southerly surface winds will return tomorrow through the latter part of the week into the weekend as another cold front settles into the area Friday into Friday night. I expect that we’ll see increased cloud cover.. increased humidity and even some rain chances Thursday into Friday and again Saturday into Saturday night.
Regarding my forecast, my local forecast confidence: My forecast confidence is very high tonight through tonight. My forecast confidence is medium to high for late week into the weekend (reference the increase in clouds and any rain chances).
Have a good Tuesday…
