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
through the balance of the seven day forecast period. This is resulting in a
stable pattern meaning a dry late summer weather pattern for our area.
We’ll continue with elevated to dangerous afternoon and evening heat stress
over the next seven days. A NWS Extreme Heat Warning until at least 7pm on
Wednesday. Please stay hydrated and take it easy out there in the afternoon
into evening hours.
After looking more closely, I will include isolated to widely scattered precipitation
for Thursday into Thursday night as an upper air low pressure disturbance
approaches the area from the north northeast. The atmosphere will remain
relatively dry with most precipitation evaporating before reaching the ground;
as a result, the rain chances remain very low for any given location with most
areas remaining dry.
Given that, as 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 seeing
in longer range climate outlooks). Another thing we need to monitor are early
fall season cold fronts and any stronger northerly winds that 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 Sunday.
