AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
A dry and stable late summer weather pattern continues. As we’ve seen the last
few days, a few isolated rain showers and storms could develop with daytime
heat in the afternoon hours between the Austin metro area/IH35 corridor and the
coast especially on Thursday but my confidence is not high enough in the model
signals that we’re seeing to mention in this in my IH35 corridor forecast.
There is now some continuity and stronger signals in model and manual
guidance suggesting a weakening surface cold front moving into our area by
midday into afternoon on Monday with perhaps better rain and storm chances
for late Sunday night into Monday.
Meanwhile, with elevated to dangerous 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
– A medium to high forecast confidence Sunday night into Monday regarding the
potential cold frontal passage any associated rain and storm chances
