… A Dry and Stable Weather Pattern To Start the New Week …
… A Weak Cold Front Due Late Wednesday into Early Thursday …
… Another Weaker Low Pressure Area and Cold Front By Late Next Weekend …
On this Monday… broad low pressure extends southward from Canada into the central USA plains. It separates higher surface pressure over the Great Lakes as well as over the intermountain west. As a result, our surface winds across south central Texas are light southwesterly.
In the upper levels of the atmosphere.. a trough, or line, of upper level low pressure extends south southeastward from Hudson Bay down along the USA eastern seaboard with the broad trough covering the eastern half of the country. A ridge, or line, of higher surface pressure extends from the eastern Pacific Ocean into the Pacific Northwest. An upper level low pressure area is located over the central and southern Baja Peninsula. Our upper level winds, at about 18,500 feet overhead, are westerly 35 to 40 mph.
A dry and stable weather pattern continues as we start the new week.
The upper level low over the Baja Peninsula will be weakening and pushing eastward over Mexico and far south Texas over the next few days. Low level moisture will begin to increase again by Wednesday into Wednesday night as the southerly surface winds become a bit more pronounced.
A southeastward moving weak cold front will move into the area between midnight Wednesday night and daybreak Thursday morning. As it does, some patchy fog and low cloudiness will develop. The real question with this front will be exactly how far south it gets before the front washes out. Early indications suggest that it will not move very far southeast of the IH35 corridor before it weakens on Thursday morning. The effect will be slightly cooler temperatures on Thursday.
Winds return south southeasterly by Thursday night into Friday with warmer temperatures returning. By Friday night into Saturday, as low level moisture increases along with atmospheric instability, we’ll see a few sprinkles developing as early as Friday night into the weekend.
The next cold front.. it this point, it appears weak.. will move eastward across the area late Saturday night into Sunday with an increased chance of rain showers and thunderstorms.
Overall, over the next seven days, I expect rainfall to average 1/4 inch or less.
Have a good Monday….
