… Rain Chances Continue On and Off Over the Next Seven Days …
On the Weather Map…
On the surface map… tropical cyclone Gordon is over the northeastern Gulf of Mexico. A trough, or line, of surface low pressure extends from a Colorado low into New Mexico and far west Texas near El Paso. As a result of this surface weather pattern, our surface winds over south central Texas are light easterly.
On the upper air map… a broad trough of upper level low pressure is deepening a bit from central Canada to over the western half of the USA. Upper air high pressure, acting like a “lid” on the atmosphere, continues over the eastern part of the USA. As a result of this upper air weather pattern, the 30,000 foot winds over our local area are light and variable less than 10 mph.
What I am Seeing As I Look Ahead…
The upper level high pressure.. or the “lid” on the atmosphere that has been present over Texas this summer.. has weakened overhead as moist unstable air spreads into the area off the Gulf of Mexico.
As a result, a moist and unstable air mass will, over the next seven day period, produce scattered on-and-off rain shower and thunderstorm activity. Some gusty winds and, of course, dangerous cloud to ground lightning will accompany the stronger thunderstorms. NWS/Weather Prediction Center rainfall guidance suggests that we’ll see, on average, 1 to 3 inches of rain between and next Monday.
As the result of cloud cover and areas of precipitation, afternoon high temperatures will be, for the first time in a while, closer to seasonal averages.
Tropical cyclone Gordon will move ashore the Mississippi coast later tonight with little effect on our sensible weather across south central Texas.
Have a good Tuesday..
