...Dangerous Heat Wave Expected This Weekend...

No changes are expected in the forecast for later this week
through early next week. On Thursday, an upper trough should move
across the northern and central Plains. Weak surface troughing and
a slight moisture increase Thursday afternoon could result in a
few showers developing over the higher terrain from the Panhandle
southward to the Permian Basin. For now, chances for rain were
kept low on Thursday afternoon and evening due to lowering
confidence levels. Even with some low rain chances the searing
heat will continue.

This weekend through early next week, an upper-level ridge should
rebuild across Oklahoma and north Texas, leading to hotter
temperatures. This heat wave could potentially be stronger and
more widespread than what we saw earlier this week as 850mb
temperatures could reach 24-27 deg C and 591 dam heights could
extend all the way to the northern Plains by Sunday. High
temperatures during this period look to reach 105-110 degrees for
most locations, especially the Concho Valley and Big Country.
Assuming this comes to fruition, Heat Advisories will likely be
needed for consecutive days this weekend. Those who will be
participating in outdoor activities this weekend, especially those
related to the start of the school year, are advised to take
precautions to limit exposure to the dangerous heat.
