&& .NEAR TERM /THROUGH TUESDAY/...
-- Changed Discussion --
The convection-supporting shortwave has shifted east of the Upper Ohio Region, but a strong forcing into the warm, unstable airmass is maintaining a thunderstorm cluster along the I 68 corridor. Local severe and heavy rainfall is anticipated in this area early this eve. Otherwise, residual showers and storms will wane as the eve progresses and cease altogether with passage of the systems dry-front. Have persisted with previous forecast which assumes sufficient southward frontal progress to preclude PoPs over southern zones on Tuesday, with exception for the southernmost areas, i.e. those adjacent to Tucker County, WV.
