AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
After a couple of days of dealing with isolated rain showers and thunderstorms
that have developed in the afternoon over the Texas coast plains and then moved
northwestward into the IH35 corridor before dissipating before sunset, I’m
throwing in the towel. I will introduce very slim chance of rain this afternoon
into this evening for the IH35 corridor with all activity diminishing by sunset.
Consider yourself lucky if you get measurable precipitation.
Otherwise, upper level high pressure, acting like a “lid” on the atmosphere, will
start to strengthen overhead tomorrow through the balance of the seven day
forecast period. This will result in a more stable pattern (and less influence from
the Gulf) meaning a dry pattern tomorrow through the weekend.
Low level humidity levels will continue through the balance of the seven day
forecast period resulting in higher afternoon and evening heat stress temperatures
particularly for Wednesday into Friday.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A high forecast confidence today.
– A very high forecast confidence for Tuesday through Sunday.
