Speaker Notes:

Low-level southerly flow oriented up the sloping front was forecast to be a fairly modest 20 kts across Pennsylvania at 12 UTC on the 6th. However, the persistent southerly flow was forecast to begin to bring in some fairly impressive precipitable water values (over an inch across southern Pennsylvania).
