AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
A dry and stable late summer weather pattern is building back over the area
and will continue through the weekend and into the first part of next week as
somewhat drier air moves into our area for particularly Friday into Saturday.
By late Monday, an approaching upper level low pressure disturbance will
move from the west coast into the southern Rockies. This will promote
increasing moisture and low level wind flow off of the Gulf. By Tuesday morning,
this system will begin to cross Texas with an associated surface cold front extending
from a developing surface low pressure area over the Kansas and Nebraska
border southwestward into west Texas and southern New Mexico. Model
and manual forecast data suggests that the front will move through our area
on Wednesday (as the first fall cold front of the season). Rain and thunderstorm
chances appear to increase by Tuesday into Wednesday before a slightly cooler
air mass taking hold, with temperatures falling a few degrees, by Thursday as
this weather pattern change takes hold.
Until that occurs, 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 at least through Thursday and again
Sunday into Monday.
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 make our way 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 especially if no precipitation occurs as the fronts move
through. 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 Monday
– A medium to high forecast confidence for Monday night into Tuesday
