AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
As we start the new week, southerly surface winds have resulted in increased low level
moisture and higher humidity. While I am maintaining a dry forecast over the next few days, some the computer models suggest a few rain showers and thunderstorms in the afternoon hours over the next few days but based on what I am seeing, I think that most of the activity will stay to our south and southeast in deep south Texas and the Texas coastal plains. As a result, I will not include any rain chances for our IH35 corridor. I will continue to watch for this possibility today and tomorrow as well as Wednesday.
A more unsettled weather pattern still looks set up beginning mid week as we see a more
distinct weather pattern change for Texas that will continue into Friday as a broad upper
level low pressure trough passes west to east into the central plains states. We will see better rain and thunderstorm chances beginning late Thursday into the predawn hours Friday as the upper level trough helps to support a relatively strong cold front as it dives southeastward through Texas. Following the cold frontal passage, surface high pressure characterized by drier and cooler conditions will be in place by late Friday through the weekend.
Beyond my seven day forecast, preliminary guidance suggests rain chances may return to
our forecast by the mid part of next week.
MY LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence now through Wednesday night
– A high forecast confidence Thursday through the weekend
