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 levels, so please remember to remain hydrated and
to “take it easy” if you’re outdoors in the afternoon and evening hours.
One final note.. some of the model guidance is suggesting a few very widely
scattered rain showers mainly to our east and southeast over the Texas coastal
plains for late Friday into Friday night. My confidence of this happening remains
quite low and, as a result, I will not mention any precipitation in my forecast at
this point. I will continue to monitor for this possibility.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A very high forecast confidence for over the next seven days.
