As towns and cities along the East Coast light Christmas trees this week, it will a little feel more like Easter, rather than Christmas.
A major flip in the weather pattern will continue to allow warmer air to surge northward over the Appalachians and Atlantic Seaboard much of this week.
Last week, Thanksgiving Day felt more like New Year's Day due to the Arctic cold, and the landscape looked more wintry with snow on the ground for some in the Northeast. AccuWeather RealFeel® temperatures were in the teens and 20s over much of the area. Temperatures averaged 10 to 20 degrees below normal.
Folks attending tree-lighting festivities from Boston to Hartford, Conn., New York City, Philadelphia and Washington, D.C., will not have to face harsh winter conditions and January-like RealFeel® temperatures. The more moderate temperatures will allow more people to spend time outdoors.
The weather could be wet for people attending the lightning of the National Christmas Tree in Washington, D.C., Friday. Plastic rain ponchos and waterproof shoes would be a good idea.
For folks taking in the sights around the District of Columbia in the morning, temperatures will start near 60. However, it will turn cooler as the day progresses with temperatures falling through the 50s then into the 40s by the evening. Have an extra layer or a warm jacket on hand for the afternoon and evening, especially with the damp conditions forecast.
During much of this week, temperatures will average 5 to 15 degrees above normal.
Whether or not you are attending official tree lighting activities this week, the higher temperatures will present a good opportunity to set up your own outdoor lighting displays, without having to worry about getting frostbitten fingers.
Colder air will press in over the weekend, but in most cases the rain will end, rather than change to snow or ice along the East coast. It could be a different story for parts of the Appalachians.
Temperatures will be a few degrees below average across the UK this weekend, but largely dry conditions are expected.
After no rain for almost a month, Santiago braces for rain early in the week. Cool air follows, spreading into Chile, Argentina and Uruguay mid-week.
There is a significant chance that Jimena will turn back toward Hawaii and threaten the islands during the second week of September.
An unusually strong push of cool air for early September will move southward along the Atlantic Seaboard into the Labor Day weekend before July-like heat returns by next week.
Steering winds could take Ignacio, as a remnant storm, into the southeastern arm of Alaska or British Columbia during the middle days of next week.
Strong thunderstorms will roll across the Upper Midwest while rain and strong winds roar through the Northwest this weekend.
Minneapolis, MN (1941)
Tornado - 5 dead - $450,000 damage.
Greatest natural disaster for Arizona. Rains in central Arizona caused rivers to rise 5-10 feet per hour, sweeping cars and buildings 30-40 feet downstream. Twenty-three lives were claimed by the floodwaters. This rain came from Tropical Storm Norma.
Los Angeles, CA (1988)
110 degrees -- all-time September record.
