…. Colder Arctic Air In Place Over Texas As We Start the Week ….
…. More Arctic Air into Texas Early Wednesday and Again over the Weekend ….
…. Clouds and Rain Chances with a Warm Up Late Week into the Weekend ….
On this Monday morning…. high pressure is building into Texas from the north… it is centered over eastern Kansas and western Missouri. As a result of this surface weather pattern, our local surface winds are northerly.
In the upper levels of the atmosphere.. a broad upper level trough.. or line.. of low pressure is centered from Hudson Bay southward over the eastern half of the USA. As a result, our upper air winds at about 18,500 feet are west northwesterly at 10 to 20 mph.
The surface high pressure area, to our north, will move eastward pretty quickly today into tonight with winds becoming more southeasterly locally by later this afternoon. Overall, a dry and stable winter weather pattern continues. With the increased south southeasterly wind flow, we’ll see a warm up tonight into tomorrow.
Another strong arctic cold front will move through the area by early Wednesday morning with high pressure settling into the area.. with much colder temperatures.. for Wednesday into Wednesday night. Temperatures will be much below average Wednesday into the latter part of the week into the weekend with a hard freeze (think: pets, pipes and plants!!) likely Wednesday night into Thursday morning.
An approaching upper level low pressure disturbance.. from the west.. will approach the area by Thursday into Friday and into the weekend with an overrunning cloud and rain pattern setting up across the area.
In the wake of the upper air disturbance, another reinforcement of modified arctic air.. not quite as cold.. is due by early Sunday with sunshine returning to the area for Sunday into the early part of next week.
Regarding my forecast, my local forecast confidence: My forecast confidence is very high through Wednesday and Wednesday night with my confidence falling back to medium for Thursday through the weekend with rain chances, timing and amounts being the issues.
Have a good Monday….
