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 over
the area. A more southerly surface wind is resulting in higher low level humidity
and this will continue through the balance of the seven day forecast period.
As this occurs, afternoon into evening temperatures will combine with the
increased atmospheric moisture and we will return to more elevated heat index and
wet bulb globe temperature values. Once we get into mid and late week through the
weekend, 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.
