AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …

In the wake of hill country rain showers and thunderstorms on Sunday, a dry and
stable late summer weather pattern appears underway as we start the new week.

Meanwhile, with elevated afternoon and evening heat stress over the coming days,
a friendly reminder to please stay hydrated and take it easy out there in the
afternoon into evening hours.

In addition, we continue to see drought conditions worsen overall over the area and
vegetation continues to dry out, wildfire danger continues to increase over
our area. So far, winds have been relatively light so the danger has been
limited. As we wrap up summer and head into the fall months, this danger will
likely continue to get worse assuming no precipitation. Another thing we need to
monitor are any early fall season cold fronts and any stronger northerly winds
that might occur with any frontal passage. Burns bans continue for our IH35
counties so I strongly discourage any outdoor burning.

LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence through Sunday night
