Severe Weather Update for This Afternoon

The above visible satellite image was taken just a few moments ago.  If you look closely, you can see towering cumulus clouds building along the dryline from southcentral Kansas (Northwest of Wichita), then basically North-South along the I-35 corridor all the way to the Red River in northcentral Texas (southwest of Ardmore, OK).

The atmosphere is becoming increasingly unstable across central and eastern Oklahoma into southcentral and southeast Kansas, and rapid thunderstorm development is likely within the next one to two hours as an upper-level weather disturbance approaches the region.

Thunderstorms will likely initially develop over Kansas, then develop southward along the dryline into Oklahoma and perhaps northcentral Texas over time.  Once thunderstorms have developed, they will move Northeast to East.

Large hail, damaging winds and isolated tornadoes are possible with any thunderstorm that forms in this region this afternoon & evening.  In particular, a threat of very large hail (baseball size or larger), and one or more long track, potentially damaging tornadoes exists over the Oklahoma portion of the above region.

Residents across the areas outlined in green below (and especially those in the area outlined in red) should remain on a high state of alert this afternoon & evening and be prepared to seek shelter immediately if threatening weather approaches:
