AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
As upper level high pressure, acting like a “lid” on the atmosphere, continues to
hold over the area, I expect the dry and stable weather pattern to continue into
the weekend.
While the upper high pressure area will settle more westward and center itself over
the inter mountain west and southwestern US by Saturday night into early next
week, a weakening surface cold front will be moving southward into central Texas
by Saturday night into the predawn hours Sunday. The atmospheric lift associated
with the front as it weakens just to our north will result in a few rain showers and
thunderstorms Saturday night into the predawn hours Sunday.
Over the seven days ahead, afternoon into evening temperatures will continue with
atmospheric moisture and will result with elevated heat index and wet bulb globe
temperature values. As usual this time of year, please remember to remain hydrated
and to “take it easy” if you’re outdoors in the afternoon and evening hours.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence for over the next seven days.
