Areas affected...Northeast Texas into ArkLaTex
Concerning...Severe potential...Watch possible
Valid 021533Z - 021730Z
Probability of Watch Issuance...40 percent
SUMMARY...All severe hazards, including very-large hail and a strong
tornado or two, are possible this afternoon.
Convective/observational trends will continue to be monitored for a
possible watch this afternoon.
DISCUSSION...Storms have recently initiated along a pre-frontal
confluence zone in Northeast Texas. Based on the observed 12Z
Shreveport, LA sounding as well as the character of boundary layer
clouds on visible satellite, there is still inhibition left to
overcome this morning. That said, objective mesoanalysis shows more
minimal amounts of MLCIN remaining right along the confluence zone.
Activity may initially struggle to intensify until greater surface
heating occurs through the day. Strong effective shear is in place,
though it is largely parallel to confluence zone and cold front that
lags to the northwest. 2000-2500 J/kg MLCAPE and steep mid-level
lapse rates will eventually support rapid storm intensification. Large/very-large hail and severe gusts would be possible. The
tornado threat will depend on the overall storm mode, which could
lean linear, but strong low-level shear apparent on regional VAD
data and a very moist airmass (mid/upper 60s F dewpoints) would
favor potential for tornadoes, some of which could be strong. Timing
of storm intensification is uncertain given the inhibition and
overall lack of a stronger/focused forcing mechanism.
Convective/observational trends will be monitored for a possible
watch this afternoon.
