Warmer and More Humid into the New Week ….
A Cold Front with a Chance of Thunderstorms for the Middle of the Week ….
Cooler.. Drier and More Stable Weather Pattern Thursday through the Weekend ….
On this Monday….deepening surface low pressure is over southern Utah with another area of low pressure over the Texas and Oklahoma panhandles. From that second low, a trough. or line.. of low pressure extends southwestward into southern New Mexico and southwest Texas. Surface high pressure is off the east coast of the USA. Given this surface pressure pattern, surface winds are southerly across our area of Texas.
Southerly surface winds have been quite efficient in returning low level moisture back to the area with late night and early morning low clouds with some patchy fog and drizzle. As the surface and upper level low pressure areas.. to our distant west and northwest.. continues to strengthen and move eastward, we’ll see the more humid weather pattern continuing over the next 24 hours.
As the upper level low pressure area out west moves eastward, a surface cold front will move southeastward into Texas by late tomorrow into tomorrow night and will move through the local area in the morning hours on Wednesday. As it approaches tomorrow night into Wednesday, scattered rain showers and thunderstorms with some storms possibly severe.. mainly north and east of Austin. The main risk will be larger hail and damaging straight line thunderstorm wind.
Cooler and drier surface high pressure will settle southeastward into Texas Wednesday night into Thursday.
As surface high pressure moves eastward by late Friday into Friday night into Saturday.. a south southeasterly wind will redevelop with a slow return in low level moisture over the weekend into early next week.
Have a good Monday night and Tuesday…
