If someone is in the Mon Valley towards the M/D line, they probably average 10-12” lower than the airport. Always get the WTOD first on moderate storms, miss out on some LES, etc.
But that general area has seen 15” + at least 6 times in the last 32 years. Official climo makes that more like a once every 10-15 year event.
Big difference was they did much better in ‘96 and especially ‘16.
Just interesting since a lot of times they lose on the dividing line, but don’t seem to miss truly big ones.
