.. A Dry Stable Weather Pattern to Start the Week ..
.. Another Cold Front with Stronger Thunderstorms Possible Midweek ..
.. Clearing and a Bit Cooler Again Late Week ..

On this Monday… a strong surface low pressure area is over the Great Lakes states with a cold front extending southward into the southeastern USA and the Gulf of Mexico. Weak surface high pressure is over east Texas as pressures lower once again over west Texas and New Mexico. As a result of this surface weather pattern, our surface winds across south central Texas are south southwesterly.

In the upper levels of the atmosphere, a deep trough.. or line of upper level low pressure.. extends southward from the Great Lakes southward through the eastern 2/3rds of the country. Another upper level low pressure disturbance is over the Baja Peninsula. As a result of this upper air weather pattern, the 30,000 foot winds over south central Texas are westerly 55 to 60 mph.

A drier and more stable air mass has moved into Texas in the wake of the Saturday evening cold front and round of rain showers and thunderstorms that affected the central and eastern parts of the area.

The upper air low pressure disturbance will deepen and move slowly east northeastward toward Texas over the next day or so. As it does, abundant low level moisture will increase over the area as the air mass grows more unstable.

By late tomorrow night into Wednesday and Wednesday night, a surface cold front, associated with the approaching/passing upper level low, will increase the lift in the atmosphere as it become increasing moist and unstable. Scattered to numerous rain showers and thunderstorms will occur over the area with the possibility of severe thunderstorms.. including the risk of larger hail, damaging thunderstorm winds and even a few tornadoes over our area. At the current time, the NWS/Storm Prediction Center has our area in a “marginal” severe thunderstorm risk but hey do indicate this risk could be increased by the time the severe weather outlooks are updated again tomorrow morning. Given the progressive nature of the system, rainfall for this event will stay below one inch.

Once this system passes by Wednesday evening, we’ll see clouds break with sunshine returning along with a little cooler temperatures for Thursday and Friday.

It looks like a sunny weekend coming up with a slow warming trend.

Have a good Monday….
