…. Arctic Air Continues its Grip on Texas ….
…. Warmer Temperatures, More Clouds and Rain Chances by Late Week into the Weekend ….
On this Monday morning…. arctic high pressure continues from Texas north northwestward into the northern and central Rockies and the intermountain west. As a result of this surface weather pattern, our local surface winds are northwesterly.
In the upper levels of the atmosphere.. a massive area of upper level low pressure area, covering much of the USA, is centered over the area from Hudson Bay south southwestward to west of Lake Superior. As a result, our upper air winds at about 18,500 feet are west northwesterly 70 to 80 mph.
Unseasonably cold temperatures continues across Texas as arctic high pressure continues to build south southeastward into Texas.
With a clear sky, I expect a widespread and potentially hard freeze across the Austin and south central Texas overnight tonight into early Tuesday morning. Temperatures are likely to fall into the 20 to 25 degree F range in outlying and low lying areas with downtown Austin likely seeing temperatures of 29 to 32 degrees F. Average lows across the city/metro area will be in the mid and upper 20s. Please remember your pets.. pipes and plants…
As surface high pressure moves east of the area and low pressure becomes better developed to the west, south southeasterly surface winds return to the area by the middle and latter part of this week, clouds and temperatures will increase once again with the slim possibility of rain. Early guidance suggests that we could see upwards of 1/4 inch of rainfall across the area with this next weather system.
Regarding my forecast, my local forecast confidence: My forecast confidence is high to very tonight through the next seven days.
Have a good Monday….
