December 2003 nor'easter: The December 2003 New England snowstorm was a severe nor'easter that impacted the Eastern United States during the first week of the month.  It produced heavy snowfall throughout the New England and Mid-Atlantic regions, locally exceeding 40 inches (1 m).  The cyclone had complex origins, involving several individual weather disturbances.  An area of low pressure primarily associated with the southern branch of the jet stream spread light precipitation across portions of the Midwest and Southeast.  The low reached the coast on December 5 and continued to produce snow throughout the Mid-Atlantic.  Another system involving the northern branch of the jet stream merged with the initial storm, causing another coastal storm to develop.  This storm soon became the primary feature as it intensified and moved northeastward.  It reached Cape Cod on December 6, but became nearly stationary through the morning of December 7.  It had finally dissipated by December 8.

WWE Extreme Rules: WWE Extreme Rules (simply known as Extreme Rules) is a professional wrestling event produced annually by WWE, a Connecticut-based promotion, and broadcast live and available only through pay-per-view (PPV) and the WWE Network.  The name of the event stems from most matches being contested under hardcore wrestling regulations; the defunct Extreme Championship Wrestling (ECW) promotion originally used the term to describe the regulations for all of its matches.  The event name was established in 2009; however, its theme began with its predecessor, One Night Stand, which was promoted in 2005 and 2006 as an ECW reunion show.  In 2007, WWE promoted the show as one of its own regular PPV events but kept the ECW concept of Extreme Rules matches.  In 2009, WWE renamed the One Night Stand event to WWE Extreme Rules.  The 2009 Extreme Rules event was noted by WWE to be a direct continuation of the One Night Stand chronology.  However, the 2010 event was later promoted as only the second event under a new chronology, one that is no longer a direct continuation of the One Night Stand events.  Starting in 2010, Extreme Rules was moved from June to late April/early May to replace Backlash as the post-WrestleMania pay-per-view event.  For 2013, the event was scheduled to take place in mid-May and replace Over the Limit, which was moved to October before being discontinued later that year and replaced by Battleground.  The event will return to the early June slot of WWE's pay-per-view calendar and will be a Raw-exclusive pay-per-view event.
