We have high pressure that is centered over New England. A front remains stretched out across the southeast and is helping to pull moisture out of the Gulf as a low pressure rides along the front. The low pressure that is currently over the Outer Banks will move off the coast Sunday morning and spread moisture up to southern Pennsylvania. Rain will continue to overspread the region into this mid-day from the low pressure. The rain will taper off by mid-day and a shower or two will be possible in the afternoon. Most of the rainfall totals will be less than a half inch.
This will also keep out temperatures in the low 70s which is 8-12 degrees below normal for this time of the year. Our average high is 85 degrees. Overnight, the rain is expected to pull off to the east and should not be a concern by daybreak Monday.
