Harrisburg, Pennsylvania

It’s Halloween, and I would like to wish you and yours a safe trick or treat experience. Nothing too spooky, I hope.

At 1215PM, ET, Harrisburg was reporting a temperature of 59 degrees with fog and overcast skies. We continue to see an upper level ridge across the Eastern Seaboard, however an easterly flow off the Atlantic has hemmed low level moisture up against the Appalachians, bringing about the fog and low clouds. The back edge of the ridge is over the mid-Mississippi Valley, and is moving swiftly east. A consequence of this jet action is a developing area of low pressure and a strong cold front moving into the Appalachians. Rain will move into Harrisburg by this evening as the low slides northeast from the Lower Ohio Valley into the Great Lakes.
Heavy rain will arrive overnight tonight, and 1-3″ of rain will fall through noon tomorrow. The front will shift out of town by the early afternoon, and temperatures should have a chance to plummet overnight Friday night into Saturday. A dry slot will move into the Appalachians, and a vigorous inverted trough through the eastern Great Lakes will be unable to reach Harrisburg on Saturday, leading to a cool, dry beginning to the weekend.
Tomorrow – Rain, especially early, High 74, Low 51
Saturday – Mostly cloudy, High 62, Low 46

TWC: Tomorrow – AM Showers / Wind High 72, Low 53

Saturday – Partly sunny, High 60, Low 47

WB: Tomorrow – Showers with a chance of thunderstorms in the morning. Some thunderstorms may produce gusty winds in the morning High 69, Low 54

You know, it’s unfortunate that the temperatures are dropping like they are, but 60 degrees in November is still pretty good. Satellite paints a pretty cloudy picture.
