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 for
our area through the seven day forecast period ahead.
Over the coming days, 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.
By Sunday, longer range numerical modeling along with the NWS/Climate
Prediction Center 8 to 14 day outlook (below) suggests a more unstable
weather may develop with a weak cold front moving into northeast Texas.
It’s still too early to call now, but we may see better precipitation chances
mainly beyond this seven day forecast period beginning as early as Sunday night.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence for over the next seven days.
