AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
A more stable and drier late summer weather pattern is setting up as we move
further into our new week.
There are some initial signs of a weather pattern chance, namely a more
unstable weather pattern and perhaps a better chance of rain, by the middle
part of next week just beyond the seven day forecast period. I’ll start looking
at this more closely in tomorrow’s update.
With elevated to dangerous afternoon and evening heat stress over the next
seven days, a friendly reminder to please stay hydrated and take it easy out
there in the afternoon into evening hours. Friday into the weekend look to be
most hazardous in regards to afternoon heat stress values.
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. At this point, I do not see a cold frontal
passage over the next seven to ten days, but I will continue to monitor things closely.
Burns bans continue for our IH35 counties so I would strongly discourage any
outdoor burning.
