Unseasonably warm conditions will continue around Harrisburg, Pa., through the weekend, ahead of possible drenching rain from Karen.
High temperatures well in the 80s and generally rain-free weather will continue around the region through the day Sunday.
However, two weather systems have a chance at bringing a dose of heavy rain by early next week.
A front from the Plains is forecast to sweep off the East coast later Tuesday. Ahead of the front, showers and thunderstorms are in store with a southerly flow of moisture early next week.
Surviving within that flow may be Karen as a tropical rainstorm.
If Karen's rain does make the trip this far north, it would raise the possibility of flash and urban flooding, as well as travel delays, most likely from the afternoon/evening drive Monday with possible lingering effects for Tuesday morning's rush hour.
Most areas need rain and could easily handle a couple of inches over a 6- to 12-hour stretch with few problems as the last thorough soaking was Sept. 21. There is a chance of heavier rainfall if Karen gets totally involved.
Winds ahead of and during the rain may be rather strong Monday.
Some areas near and just east of the track of the center of circulation of Karen could be hit with a severe thunderstorm during Monday/Monday evening.
The air behind the front and/or Karen next week will be cooler than this week, but not abnormally so. Temperatures will still average near to above normal for the rest of next week.
