AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
Upper level high pressure, acting like a “lid” on the atmosphere, continues
to strengthen through the balance of the seven day forecast period. This will
result in a more stable pattern (and less influence from the Gulf) meaning a
dry pattern tomorrow through the weekend into next week.
Low level humidity levels will continue through the balance of the seven day
forecast period resulting in higher afternoon and evening heat stress over
the next seven days. Take it easy out there in the afternoon into evening hours..
remain hydrated!!
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence through next Tuesday.
