Good Morning, Del Rio!
Below I was able to capture a fantastic satellite image loop from the National Oceanic and Atmospheric Administration's brand new GOES-16 Satellite. As the sun rose this morning, the visible-light spectrum of the satellite opened up to an abundance of clouds over the state, with a beautiful top-down perspective of massive thunderstorm over the Big Bend National Park, and a smaller, but equally as intense thunderstorm near Corpus-Christi.
What's in store today for the Del Rio area? Great Question!
Forecasting geniuses have been rather stumped over the last week or so about severe weather through the Rio Grande Plains. While atmospheric dynamics would certainly support severe weather - the atmosphere has under-performed substantially.
Yesterday was the first day that any confirmed severe weather was actually observed through the region - and that particular storm dropped some large hail near the small town of Knippa - just east of Uvalde. A storm late in the afternoon on Friday also raised some concern, but stayed on the Coahuila side of the Rio and went unconfirmed.
Another clue that I observed today with the weather balloon data indicated ample wind shear from the ground level to toe stratosphere. This is also conducive to thunderstorm growth because it has the ability to sustain storms by separating the updraft of moisture from the downdraft of rainfall, This allows storms to continue to "feed" with moisture rather than rain themselves out.
Lastly, what I observed the amount of moisture through the atmosphere - known as Precipitable Water. Today - the atmosphere over Del Rio is near it's maximum value for this time of year in regards to moisture content. In other words - there's a lot of moisture aloft over the region that could, under the right conditions, initiate some localized flooding.
