Areas affected...Parts of north FL

Concerning...Tornado Watch 720...

Valid 101844Z - 102015Z

The severe weather threat for Tornado Watch 720 continues.

SUMMARY...Some uptick in the severe threat is possible this
afternoon, including the potential for locally damaging wind and a
brief tornado or two.

DISCUSSION...The northern portion of an extensive QLCS is moving
across the northern FL Peninsula early this afternoon. The inland
portion of this QLCS has recently remained subsevere, but some
diurnal heating and steepening of low-level lapse rates through the
afternoon may support an uptick in damaging-wind potential as the
line continues to move eastward, especially as a stronger line
segment noted west-northwest of Tampa eventually moves onshore.
Also, some increase in low-level flow/shear is expected with time,
in response to a shortwave trough quickly approaching the area from
the west. This may support some threat for a brief, line-embedded
tornado or two later this afternoon. 

Some local expansion of the watch may be needed later this
afternoon, depending on the evolution of offshore convection and
also the line segment currently noted west of Jacksonville.
