AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
In the wake of yesterday’s storms, upper level high pressure, acting like a “lid”
on the atmosphere, has rebuilt over the area and will stay this way through the
balance of the seven day forecast period with the surface front that moved in
yesterday weakening and returning northward as a warm front. This means we’re
back to a stable pattern meaning dry late summer for our area.
We’ll continue with elevated to dangerous afternoon and evening heat stress
over the next seven days. A NWS Heat Advisory may once again become
necessary. Over the coming days, please stay hydrated and take it easy out
there in the afternoon into evening hours.
In addition, we continue to see drought conditions worsen over the area and
vegetation continues to dry out, wildfire danger continues to slowly increase over
our area. So far, winds have been relatively light so the danger has been limited.
As we wrap up summer in September and head into the fall months, this danger
will likely continue to get worse assuming no precipitation (which I’m not really
seeing in longer range climate outlooks). Another thing we need to monitor are
any early fall season cold fronts and any stronger northerly winds that might
occur with their passage. As I mention, I do not see either of these things happening
at this point, but I will continue to monitor things closely. Burns bans have been
posted for our IH35 counties so I would strongly discourage any outdoor burning.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence through next Thursday.
