AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
Over the next 24 to 48 hours, a strong upper level low pressure disturbance will be
moving east northeastward into Texas. Abundant amounts of atmospheric moisture, at
all levels, from the south has moved northward into Texas as the atmosphere senses
the main upper level low pressure disturbance to our north northwest.
This is combining with the upper level low pressure disturbance and an eastward moving
cold front promoting dynamic and abundant atmospheric lift as they moves through Texas.
This is resulting in widespread rain shower and thunderstorm activity. By afternoon today,
a slow moving cold front will pass through our area and move to the east with some
precipitation lingering behind the front late today through the weekend as cooler air arrives.
This sort of weather pattern is well known for it’s ability to produce excessive rainfall
amounts so periods of heavier rain and even some flooding is likely locally so let’s continue
our flood awareness through today.
Guidance suggests a second cold front may move in from the north northeast by late Sunday
into Monday and Tuesday Tuesday as cooler and drier air arrives in our area with sunshine
returning and continuing through much of next week.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A high to very high forecast confidence through the next seven day forecast period
