1155 pm cst sat dec 21 2013

areas affected...ern oh...wrn pa and nrn wv

concerning...severe potential...watch possible

valid 220555z - 220730z

probability of watch issuance...40 percent

summary...an isolated wind damage threat may continue for a few more
hours across ern oh and may affect wrn pa and nrn wv. a brief
tornado will also be possible with the stronger portion of the line
across se oh. ww issuance can not be ruled out across the mcd area.

discussion...a fine line currently extends from a 999 mb sfc low
just south of cleveland oh sswwd into ern ky. sfc dewpoints ahead of
the line are in the upper 50s f and instability is weak.
however...objective analysis shows a very strong low-level jet in
cntrl ky with winds speed around 80 kt . this feature along with a
forward speed of the line at 55 kt will make wind damage possible
over the next 1 to 2 hours as the fine line approaches wrn pa and
nwrn wv. further to the south...due to the very strong low-level
shear...a brief tornado can not be ruled out near the oh river on
the oh-wv stateline.
