That's a combo of the titles of two entries I posted last November, "November Strikes Again" and "November 15."
November 15 is notorious for the major severe weather outbreaks that occurred in back-to-back-to-back years in the late 1980s (1987, 1988, and 1989), culminating with the Huntsville, Alabama tornado.
Then, in 2005 on the anniversary date, came another big outbreak which included the F4 tornado in Madisonville, Kentucky.
Now in 2006: another November 15, another round of tornadoes and severe thunderstorms.
Tomorrow, should I begin composing the blog entry for November 15, 2007? Will next year make for another trifecta?
Of course, although it's no accident that the 15th has been active -- mid-November is squarely part of the tornado "second season" -- it's also to some extent just coincidence that this particular date is the one on which these outbreaks keep happening as opposed to, say, the 14th.
Per a blog entry Dr. Forbes wrote at this time last year, since the early 1990s a number of large multi-day events have also occurred just after November 20 (1992, 2001, 2004) as well as one earlier in the month (Nov. 9-12, 2002).
Generally at this time of year they take place, like today, in the southern tier of states near the Gulf Coast (the so-called "Dixie Alley"), although in recent years vicious tornadoes have also struck farther north as was the case with the Van Wert, Ohio tornado in '02 and the deadly one near Evansville, Indiana in November '05.
Today's outbreak could have been even worse in terms of overall intensity and geographical scope if things had been just a little different; there were some limiting factors that appear to have kept it from quite being in the league of most of the ones mentioned above, but enough atmospheric ingredients did come together to bring destruction.
There's already been confirmation of a tornado of F3 intensity near Sumrall, Mississippi during the wee hours this morning (below is a radar image at 2:35 am CST, around the time the twister was spawned by the supercell circled in yellow), and assessments elsewhere across the South are ongoing to determine how many damage reports were associated with tornadoes vs. straight-line winds.

Some of the areas in southern Mississippi which got hit, by the way, also experienced intense winds as Hurricane Katrina moved inland, and speaking of places affected by Katrina, Gulfport received more than 7" of rain today.
On the backside of the low pressure system which triggered the thunderstorms, strong winds buffeted Texas and Oklahoma.
MEANWHILE, IN THE PACIFIC NORTHWEST ...

Yet another storm! In addition to the extreme wind gusts in coastal and mountain locations noted above, it caused power outages in Portland; in Washington, disruption of ferry service on a couple of routes and closure of the Hood Canal bridge for awhile; strong winds and choppy water on the Puget Sound; and enough rain for Seattle to break its November monthly rainfall record -- and we're only halfway through the month! This means that two of the city's wettest six months on record have occurred during 2006:

AND A TSUNAMI IN CALIFORNIA!
Last but not least, to add insult to injury, a tsunami hit the West Coast of the U.S. today. That's right, a tsunami. Although at most locations around the Pacific Ocean the 8.3 earthquake near Japan resulted in only a negligible rise in water level, apparently Crescent City, California was one of the exceptions to that, with a surge of water reportedly as high as 6' which destroyed docks and knocked boats loose. Check out the trace of the water level there and notice how erratic it suddenly became ...

Crescent City was the site of a deadly tsunami in 1964 which was caused by the extreme (magnitude 9.2) Alaska earthquake.
UPDATE NOON EST 11/16:
Although for the most part things calmed down a bit overnight, with no additional tornadoes being reported after last evening, ingredients came together again for an intense supercell over eastern North Carolina shortly before sunrise, where unfortunately people have been killed by a tornado that struck near Riegelwood, which is just west of Wilmington. The number of reported fatalities has been rising by the hour.
The supercell was at the southern tip of a large area of showers and thunderstorms moving up into the mid-Atlantic region, sort of like a "tail-end Charlie" that storm chasers refer to, although typically one of those is at the end of a more discrete line (either solid or broken) of intense thunderstorms, not a more amorphous blob of precipitation like this morning (the heavier rain embedded within notwithstanding).
But the idea is the same: warm, moist, unstable air flowing into the southern end of the activity unimpeded on the heels of a strong low-level jet, in this case sweeping in right off the Atlantic and the Gulf Stream.
You can see on this regional radar how the tornado-producing storm was the strongest one around, in fact the only one anywhere within the weather system at the time capable of producing a tornado -- but all it takes is one in the wrong place at the wrong time to result in tragedy.

Here's a close-up:

Be prepared, make sure your family is ready to weather the storm.
