.DISCUSSION...

Vast upper low remains the story for the mid-state. This upper low
now centered just to our northwest, and is slowly making it's way
into the OH valley...where it will be later tonight. The upper low
will go through several changes but either way we are looking at a
deep trough remaining over the eastern US into the weekend, with
the axis remaining over the mid-state through Friday. SFC/LL
features remain weak/disorganized but a weak boundary is expected
to push by Friday night/early Saturday as the upper trough axis
moves east off the plateau. Finally some drying showing up behind
this boundary through the weekend, and another weak front is
looking to pass on Monday.

This set up will keep fairly high pops running at least through
Friday night, with chances finally dropping off as we work into
the weekend. Currently parameters are such that at times, mainly
afternoon and evenings, instability and shear become a little
elevated but severe storm chances look to remain low.

As for this afternoon and evening however, we are seeing both
instability and shear climbing, especially across of southwest.
Convection from earlier likely leaving a few boundaries to work
with, and these may light up a bit late today/early tonight.
Still, it does not look like more than isolated strong/severe
storms but parameters will definitely be there later.
