....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
THE OHIO VALLEY AND MID-ATLANTIC...

....SUMMARY...
Scattered strong to severe thunderstorms are possible across parts
of the Ohio Valley and the Mid-Atlantic on Monday.

....Synopsis...
A mid-level trough will amplify as it moves through the western
Great Lakes on Monday. Meanwhile, mid-level ridging will remain
persistent across the western CONUS. At the surface, a cold front
will move across the southern Great Lakes and Ohio Valley. High
pressure will build into the Plains in the wake of this cold front.

....Ohio Valley...
Moderate instability is forecast to develop ahead of the cold front
in the Ohio Valley on Monday with dewpoints in the low 70s and
temperatures warming to near 80. Mid-level flow around 25 to 30
knots may provide sufficient shear for some multicell clusters with
a threat for damaging wind gusts Monday afternoon/evening. This
threat should be mostly diurnally driven and wane after dark.

....Mid-Atlantic...
Moderate instability is forecast east of the Appalachians on Monday
as temperatures warm into the low to mid 90s with dewpoints in the
mid to upper 60s. Shear will be quite weak, but steep low-level
lapse rates will support some threat for damaging wind gusts.
