Mesoscale Discussion 0392

0257 AM CDT Tue Apr 09 2024
Areas affected…North-Central into Northeast TX
Concerning…Severe Thunderstorm Watch 93…
Valid 090757Z – 090930Z
The severe weather threat for Severe Thunderstorm Watch 93
continues.
SUMMARY…Isolated damaging gusts will remain possible for the next
few hours from north-central Texas into northeast Texas.
DISCUSSION…Recent surface analysis places a meso-low coincident
with the ongoing thunderstorm over northeast portions of the
Metroplex. An outflow-augmented cold front extends southwestward
from this low into southwest TX. A warm front also extends eastward
from this low into northeast TX. Airmass to the east of the ongoing
thunderstorm is characterized by low-level stability beneath steep
mid-level lapse rates and moderate deep-layer vertical shear. This
environment supports the persistence of the ongoing storms as they
continue eastward, likely trending more elevated with time. Even so,
occasionally strong to severe downdrafts could still reach the
surface over the next hour or two, particularly as this storm
interacts with the warm front (as evidenced by a recent gust of 53
kt at KDFW).
Farther south and west, the airmass is not as hostile to
surface-based storms and additional development along the
southeastward-progressing front/outflow is possible. However, the
notably dry mid-levels will likely act as a deterrent for sustained
updrafts, limiting the likelihood for mature updrafts and keeping
the overall severe potential low.
