AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
Trailing upper air disturbances are moving west-to-east overhead and will
keep gulf moisture streaming up and over the surface based cooler air which
has settled over our area. This is resulting in extensive clouds and high
precipitation chances today into early tonight before tapering off. As we’ve
seen, this weather system is quite efficient as far as rainfall rates are concerned
with the possibility of heavier rain and localized urban, small stream and even
a few cases of flash flooding today.
I expect decreasing clouds late tonight with skies partially clearing tomorrow.
Sunshine continues with a warming trend on Sunday into Monday and Tuesday.
Low pressure approaching from the west and another cold front moving into
Texas from the north will result in increased clouds and slim rain chances by
the middle and latter part of next week.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– High to very high forecast confidence through Tuesday..
– Low to medium forecast confidence Wednesday and Thursday..
