AUSTIN / IH35 CORRIDOR
MY SEVEN DAY WEATHER THOUGHTS
AND MY 7 DAY FORECAST CONFIDENCE …
The summer weather pattern associated with broad upper level high
pressure has resulted a “lid” which has limited upward motion and
kept our weather dry over the last couple of weeks.
In the last 24 hours, however, we’ve seen a subtle shift in the position of
the upper level high more to our distant west and northwest. Given the
clockwise wind around the upper level high pressure area, we have
seen weak upper level low pressure disturbances moving southeastward
into central Texas. One of those disturbances has produced some
overnight rain shower and thunderstorm activity which made it’d way
southeastward into our area from north and northwest Texas.
Similarly, another disturbance will move southeastward into our area by later
today into tonight with another chance of some rain and storms.
By tomorrow into Friday, we’ll see more sunshine and a drier pattern return
with afternoon heat stress values increasing once again.
Longer range guidance suggests that another disturbance or two will move
southeastward into our area by Saturday into Sunday with rain and some
storms returning to our forecast.
Please remember, over the coming days, that with slightly elevated to
elevated heat stress and web bulb globe temperature values in the afternoon
into early evening hours, please remain hydrated and don’t “over do it” in
regards to midday, afternoon and early evening outdoor activities.
LOCAL FORECAST CONFIDENCE FOR THIS SEVEN DAY FORECAST PERIOD …
– A high to very high forecast confidence today through next Sunday.
