AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
A and unstable tropical air mass from the Gulf has settled overhead as a
weakening frontal boundary over north Texas nudges southward creating
atmospheric lift resulting in high precipitation chances over the next few days.
The increased cloud cover as well as higher rain and thunderstorm chances
continue into Thursday and it is in this time period that I expect the heavier
rainfall totals area wide especially in areas west of the IH35 corridor through
the Texas Hill Country and the Edwards Plateau where a flood watch continues.
As I pointed out yesterday, the tropical air mass in place will result in rainfall
rates that will be quite efficient with several inches of rain possible in relatively
short periods of time. Afternoon high temperatures, with the more extensive
cloud cover and precipitation in place, will fall below seasonal averages over
the next few days.
Rain chances will drop from the forecast by late Thursday night as our atmosphere
becomes more stable once again as clouds break and afternoon high temperatures
rebound back to seasonal averages Friday through the weekend and into early
next week.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A medium to high forecast confidence today through Thursday night
– A high to very high forecast confidence Friday through Sunday.
