AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
In the wake of the weak cold front and mainly drier air that arrived in its wake,
upper level high pressure, acting like a “lid” on the atmosphere, will restrengthen
over the area. The drier air will hold today into tonight before a south southeasterly
surface wind returns with increased low level humidity tomorrow into Wednesday
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 even closer to dangerous, 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.
