AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
The tropical system over the Texas coastal waters is departing to the
northeast as a drier and more stable air mass becomes more established
overhead. As a result, we’re headed into a break in the precipitation for
the IH35 corridor over the next 48 hour period.
Another weak low pressure disturbance looks to approach our area from
the west and northwest by Friday and Saturday with rain and storm
chances returning to our IH35 corridor forecast.
A drier weather pattern arrives by Sunday into Monday.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– High to very high forecast confidence through tomorrow..
– High forecast confidence tonight through Tuesday..
