Harrisburg, Pennsylvania

Happy Halloween! Let’s head to the capital of the Keystone State to see what they have to fright or delight us with.

At 1256PM, ET, Harrisburg was reporting a temperature of 61 degrees with mostly sunny skies. An area of low pressure in northern Quebec, and a strong jet just to the west of Harrisburg was allowing for a pleasant warm up in eastern Pennsylvania. Both were contributing to some rain in western Pennsylvania, however the emergence of a new feature over Texas will erode the rainy spots, and prevent the line from stretching into Harrisburg. 
The southern low, organizing at the base of an upper level trough, will intensify and shift swiftly to the northeast tonight, A warm front will pass in the wee hours in Harrisburg tomorrow morning, with a shot at light rain, and more warm air during the day. The central low is forecast to intercept central Pennsylvania directly late tomorrow. Meanwhile, the strong south to north jet is going to continue drifting eastward. A kink in the jet will give rise to a stronger area of development in the Carolinas, and a bona fide Nor’Easter looks n coming late on Friday.
