We’re headed for Amish country with our forecast tonight. Are we going to be able to enjoy a nice weekend in Lancaster, or does Mother Nature have other things in mind?
At 953PM, ET, Lancaster was reporting a temperature of 69 degrees with clear skies, though a few locations around the region were reporting clouds, while the valleys were starting to report some light haze. Lancaster was seeing a dew point of 65, and coupled with the clear skies, it seems as though fog is inevitable tonight.
A sharp mid level trough moving through the Northern Plains is also generating the warm, moisture rich southerly flow in the mid-Atlantic, which will continue tomorrow, making things unseasonably warm, and still fairly sticky, though Tropical Storm Nate, moving into the Gulf will intercept some of the moisture as it tries to flow to the northeast. A cold front associated with the trough in the Plains will arrive early in the day Sunday, bringing some morning showers and storms, but Nate in his press for landfall, will cut off moisture for the cold front, allowing things to dry up Sunday afternoon, despite the increasing rainfall in the southeast. The cold front itself will also stall before passing through Lancaster, meaning an even more vigorous induction of warm, moist air, even without additional rain showers.

Some rain is coming thanks to the feature moving through the Plains, but Nate will indeed move through southeastern Pennsylvania early next week. Right now, satellite is pretty innocuous in the Mid-Atlantic.
