Unseasonably warm conditions will continue around Philadelphia through the weekend, ahead of possible drenching rain from Karen.
High temperatures 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 from Monday afternoon into early Tuesday.
A front from the Plains is forecast to sweep off the East coast later Tuesday. Ahead of the front early next week, showers and thunderstorms are in store with a southerly flow of moisture.
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 during the evening rush hour Monday, perhaps lingering into Tuesday morning's rush hour.
Most areas could easily handle a couple of inches of rain with few problems as the last thorough soaking was Sept. 21 and 22. There is a chance of heavier rainfall if Karen gets totally involved.
Southerly winds ahead of and during the rain may be rather strong and gusty Monday. Tides may run a foot or two above published values at the New Jersey shore and the upper part of the Delaware Bay as a result.
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.
Joaquin continues its journey across the northern Atlantic toward Europe, where it is expected to impact Spain and Portugal this weekend.
Winter will kick off with mild weather in the Northeast and mid-Atlantic as an intensifying El Nino influences the weather pattern across the country.
A fall-like weekend is in store for the Northeast, after rain and thunderstorms will dampen the region on Friday.
Another round of rain is expected to move through the Carolinas on Saturday, which may lead to rises on some small streams and creeks.
Oho will hit parts of British Columbia and Alaska with drenching rain, gusty winds and pounding seas before the week comes to an end.
“It was by far the most intimidating natural disaster I have ever chased,” Storm Chaser and Extreme Meteorologist Reed Timmer said of the historic flooding in South Carolina.
