Concerning...Tornado Watch 241...
Valid 270253Z - 270500Z
The severe weather threat for Tornado Watch 241 continues.
SUMMARY...The threat for mainly large hail and localized wind damage
is expected to persist from portions of eastern New Mexico into
western Texas, and a new watch may be needed prior to 04Z. A brief
tornado cannot be ruled out.
DISCUSSION...Slow-moving, meandering storms persist over mainly two
areas. The first is over east-central NM near western portions of an
old outflow boundary. This area of convergence intersects an axis of
instability extending north out of southwest TX. Gusty southeasterly
surface winds are maintaining boundary-layer mixing, and helping to
keep surface temperatures relatively warm, up to around 80 F.
Another more active area has been over southwest TX, where numerous
storms persist, some splitting. Recently, a storm or two has shown
signs of hail over 2.00" diameter.
Given the aforementioned boundary-layer mixing, and ample/deep
moisture profiles, convective inhibition should remain low enough
for storms to persist for several more hours. As such, a new watch
will need to be considered for later tonight.
