AUSTIN / IH35 CORRIDOR
SEVEN DAY WEATHER HEADLINES
AND MY 7 DAY FORECAST CONFIDENCE …
(1) A general dry and stable summer like weather pattern is in place overhead even as the upper level high pressure system – think “lid” on the atmosphere – has weakened somewhat over the last 24 hours. Even so, afternoon temperatures in the upper 90s to around the 100 degree mark will continue through the remainder of the week with some continued weakening of the “lid” by the weekend into early next week with temperatures falling a few degrees.
(2) As the upper level high pressure weakens, I will introduce slim rain and storm chances for tomorrow and Saturday and again Monday night into Tuesday as weak upper level low pressure disturbances move east northeastward, mainly during the peak heating hours, across our area. Make no mistake, though, these are slim rain chances and will produce relatively little in the way of rainfall.
Based on NWS/Weather Prediction Center data and guidance, my forecast is for less than 0.20 inch of rainfall for our IH35 corridor counties through the 7 day forecast period which ends in the early morning hours next Thursday.
MY LOCAL FORECAST CONFIDENCE OVER THE NEXT SEVEN DAYS…
A high confidence forecast through the next seven days.
