Areas affected...a part of east TX

Concerning...Severe potential...Watch possible 

Valid 281446Z - 281615Z

Probability of Watch Issuance...60 percent

SUMMARY...Short-line segment moving east-northeast into a part of
east Texas may intensify as the downstream air mass slowly
destabilizes into the afternoon. A couple brief tornadoes and
locally damaging winds are possible.

DISCUSSION...Remnants of the largely decaying early morning MCS have
maintained a short-line segment within the TX Triangle. KGRK radar
has detected transient mesovortices along its leading edge, which is
overlapping with the western periphery of the stronger low-level
shear environment across east TX per HGX/CRP VWP data. While surface
wind gusts have been sub-severe thus far, primary threat will be
potential for a couple brief tornadoes as the line segment shifts
towards the I-45 corridor. Downstream air mass is slowly
destabilizing amid pervasive cloud cover, but this process could
support gradual intensification into the afternoon. 12Z CAM guidance
differs in how extensive/intense this convection will be prior to
later in the afternoon.
