CORRECTED FOR SPELLING
The severe weather threat for Tornado Watch 8 continues.
SUMMARY...Isolated tornado threat remains across most of WW08.
DISCUSSION...Long-lived supercell that developed over central TX has
lifted north into the south side of the Metroplex, currently over
eastern Johnson county. Several tornadoes have likely been produced
with this cyclical storm. Air mass over eastern Tarrant and Dallas
counties has recovered sufficiently, with dew points near 64F, for
this near-surface based storm to maintain its intensity as it tracks
into southeast Tarrant county and likely into western Dallas county.
Well-organized squall line is progressing steadily east at roughly
30kt and should track across the remainder of the watch over the
next few hours. A few supercells are embedded along the southern
portion of this line and this activity should approach the
western/northern portions of the San Antonio metro within the next
