.. A Stronger Cold Front with a Chance of Thunderstorms by Late Saturday ..
.. Cooler Temperatures Sunday into Monday ..
On this Friday… a northeastward moving warm front extends southeastward from a surface low pressure area over west central Texas through east Texas into Louisiana and southern Mississippi. A cold front extends from the low pressure area through west Texas and west central New Mexico. As a result of this surface weather pattern, our surface winds across south central Texas are southerly.
In the upper levels of the atmosphere, a deep trough.. or line of upper level low pressure.. extends southward from central and western Canada through the western 2/3rds of the USA. As a result of this upper air weather pattern, the 30,000 foot winds over south central Texas are west southwesterly 55 to 65 mph.
Surface winds have returned back southerly with low level moisture quickly returning to the area.
As a dynamic area of upper air low pressure moves eastward through the southwestern USA into the southern and central plains by late tonight into tomorrow, a stronger area of surface low pressure and associated cold front will advance quickly into Texas. The cold front will pass through the local area late Saturday night. With abundant low level moisture in place along with instability and atmospheric lift accompanying the system, the latest guidance from the NWS/Storm Prediction Center suggests prefrontal thunderstorms over the area with stronger, potentially severe, thunderstorms mainly in areas to our north over north and east Texas and Oklahoma and areas eastward.
A drier.. more stable and a cooler air mass will move into Texas in the wake of the front for most of the day Sunday through Sunday night into early next week.
Another low pressure area and cold front will progress southeastward across the area late next Wednesday with another chance of rain showers and thunderstorms. Slightly cooler and drier air will advance into the area again by Wednesday night into Thursday.
Have a good Friday….
