A warm front remained relatively stationary across the Upper Ohio Valley on January 3rd. An anomalously moist and warm air mass surged northward into the zone of convergence associated with the boundary, and combined with elevated instability to create enhanced rainfall rates. In southwest Pennsylvania, Greene and Fayette Counties received the brunt of the rainfall, with storm total amounts of 1.5 to 2 inches in some cases. This rain led to some relatively minor road flooding reports.
