AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
The likelihood of rain and storms continues for our IH35 corridor with the possibility of
periods of heavier rain into Sunday as passing upper level low pressure disturbances move eastward overhead. Between the disturbances, we will see some periods of calmer weather. With the expected overall clouds and precipitation, however, temperatures will be a little below seasonal averages.
As the ground becomes more moist, it is likely we’ll see some localized flooding and even
some flash flooding particularly tomorrow into Sunday as another weak cold front moves
down into our area. Clouds and rain chances are likely to continue early next week although the rain chances decrease a bit for Monday (Memorial Day) into Tuesday before another disturbance approaches the area with better rain chances and some heavier periods of rain again for next Wednesday.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– High to very high forecast confidence through the next seven days..
