Severe Weather Update for Overnight Hours; Preview of Thursday

The above composite radar image was taken just a moment ago.  You can see strong to severe thunderstorms extending from southcentral through northeast Texas.  Earlier strong to severe activity across Oklahoma has weakened as it moved toward the Arkansas border.

Thunderstorms tried, but failed, to redevelop along the dryline over southwest Kansas and northwest Oklahoma this evening.  The widespread thunderstorm activity earlier in the day just worked over the atmosphere too much and it was unable to recover enough to support vigorous, new development.

The greatest threat of severe weather overnight tonight will take place across southcentral Texas, as moist, unstable air continues to flow Northward from the Gulf of Mexico.  Large hail & damaging winds will be possible with this activity.

A renewed threat of severe weather will take place on Thursday, across central and eastern portions of the region affected today.  Below is the latest severe weather outlook for tomorrow from the SPC:

Severe thunderstorms are possible anywhere within the yellow shaded region on the image above.  The greatest threat of severe weather, including large hail & possible tornadoes, will take place across the red and black hatched region on the image below, which includes the Springfield, MO, Ft. Smith, AR, Dallas, TX, Austin & San Antonio, TX areas:

If you live in the above regions, pay attention to the weather on Thursday.  Check back to the blog for updates throughout the day.
