AUSTIN / IH35 CORRIDOR
SEVEN DAY WEATHER HEADLINES
AND MY 7 DAY FORECAST CONFIDENCE …
(1) A weak upper level ridge continues just to the east of the area. It will strengthen a little and become a bit more dominant by the weekend. Afternoon high temperatures will combine with humidity to produce elevated afternoon heat stress levels through late week then more excessive values by the weekend.
(2) You may notice hazy conditions with Saharan dust in the area through the first half of the week.
(3) Until the upper level ridge strengthens a bit and given the relative poor performance recently of the short range / high resolution guidance as it regards how far northwest afternoon rain showers and thunderstorms have made it through the coastal plains, I will continue with a very slim chance of rain showers and thunderstorms today into Friday but rain chances will admittedly be mainly east and southeast of the Austin metro area/IH35 corridor and south of the US79 corridor.
Based on NWS/Weather Prediction Center data and guidance, my forecast is for less than 0.10 inch of rainfall for our IH35 corridor counties over the 7 day forecast period which ends in the early morning hours next Tuesday.
MY LOCAL FORECAST CONFIDENCE OVER THE NEXT SEVEN DAYS…
A high to very high confidence forecast through the next seven days.
