… A Dry and More Stable Weather Pattern Continues …
… Low Pressure Storm System Approaching By the Weekend into Next Week …
On the Weather Map…
On the surface map… low pressure is over the eastern USA with a series of cold fronts extending southward into Florida and Cuba. High pressure, northwest of the front, is over the plains states. As a result of this surface weather pattern, our surface winds are light.
On the upper air map… a low pressure trough (a “line” of low pressure) extends south southeastward from the Great Lakes into the eastern USA. As result of the upper air weather pattern, the 30,000 foot winds over our local area are northwesterly 80 to 90 mph.
What I am Seeing As I Look Ahead…
A dry and stable weather pattern through today. By later tonight into tomorrow, surface high pressure, and its associated clockwise wind flow, will move east of the area with a return south southeasterly surface wind flow across south central Texas.
Enough moisture will show up for noticeable higher humidity, an increase in cloud cover by Friday and even slim rain shower and thunderstorm chances for the latter part of the upcoming weekend. At this point, however, I don’t see another cold frontal passage until sometime next week so any rain chances for Sunday will remain, as mentioned, on the slim side; rain chances will increase Monday into Tuesday.
A warming trend is expected through the weekend. The latest NWS/Weather Prediction Center guidance has increased rainfall averages to 1/2 to 1 inch through the next seven days or so for south central Texas.
Have a good Wednesday..
