A Typical Late Spring Weather Pattern ….
No Frontal Passages/Air Mass Changes over the Next Seven Days ….
On this Tuesday morning…. surface high pressure is off the southeastern coast of the USA over the western Atlantic Ocean with another weaker high out west over the four corners region. A cold front is moving southward over central and western Kansas and eastern Colorado with a surface low along the front over southwestern Kansas. A trough.. or line.. of surface low pressure extends south southwestward from the surface low into eastern New Mexico and far west Texas. Given this surface pressure pattern, surface winds are southerly across our area of the state.
In the upper levels of the atmosphere… an upper level trough.. or line.. of low pressure is over the western third of the USA. As a result of this upper air pattern, winds over south central Texas and the Austin metro area about 18,000 feet above the ground are northwesterly 10 to 20 mph.
A pretty typical late spring weather pattern continues across our area. Late night and early morning low cloudiness continues with an otherwise a partly cloudy sky with near above average daytime high temperatures.
As the trough.. or line.. of upper level low pressure to our west lifts northeastward, it is possible that a few thunderstorms that develop out west could make it as far east as the IH35 corridor by tomorrow into Thursday and over the weekend as a cold front makes a unsuccessful attempt to move into central Texas. Any risk of stronger or severe thunderstorms over the coming days should remain well to our west and northwest through the end of the week.
Have a good Tuesday night and Wednesday…
