Forecast for Sunday, October 21, 2012

High pressure remains in control of our weather through Monday Night. On Tuesday, a weak warm front will move into the region and slowly drift northward, before dropping back down as a cold front. This cold front will likely never make it through our region as it likely falls apart. On Saturday Night or Sunday, there is decent confidence that a very strong cold front will move through the region and a substantial temperature drop is quite possible behind that boundary. Before then, this new week will end warm with high temperatures in the seventies.

The NWS Office in State College is currently conducting a storm survey in Lancaster and York Counties to determine whether some of the structural damage during a severe thunderstorm episode yesterday was caused by a tornado. The results of this survey are expected later this evening. A strongly worded severe thunderstorm warning was issued for Lancaster County with the mention of weak rotation…but the only tornado warning in our area was in Berks County where no damage was reported.
