AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
Upper level high pressure, acting like a “lid” on the atmosphere, continues to our
northwest resulting in a stable summer weather pattern. A more southerly surface
wind has resulted in higher low level humidity levels and this will continue through
the balance of the seven day forecast period.
While I will keep my IH35 corridor forecast rain free, we need to watch for a few
afternoon into early evening rain showers and thunderstorms to our east and
southeast over east and southeast Texas and the Texas coastal plains. At this
point, my confidence is quite low that this activity would ever reach as far west
as our IH35 corridor.
As we’ve seen lately, afternoon into evening temperatures are combining with the
increased atmospheric moisture and resulting in more elevated heat index and
wet bulb globe temperature values. The heat index and wet bulb globe temperature
values will rise a bit higher and, at times, even a little closer to dangerous levels, so
please remember to remain hydrated and to “take it easy” if you’re outdoors in the
afternoon and evening hours.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence for over the next seven days.
