"Not enough time..."

SYNOPSIS  (for those with not enough time)
- Pacfic Ocean temperature anomalies due to the current El Nino cycle remain above historical averages, suggesting that stormy weather will persist through the Spring for much of the Eastern U.S.
- Colder conditions are expected this weekend across the Mid-Atlantic and Northeast as a storm system travels through the southeast while high pressure orients near the Great Lakes.  Brief periods of snow are possible late Friday into Saturday for parts of the Mid-Atlantic.

6:00 AM TUESDAY 3.23.2010  From the not-yet-recovered flood waters of the northeast to the snowmelt floods of the northern plains or the latest round of winter weather in the southern plains -- there's been not enough time in between events for residents to catch a break from the onslaught of 2010. It has been a "Wherever you are" year, as much of the planet has endured a more variable fall-winter-early spring due largely to the cyclical nature of the 2009-2010 El Nino.

As reported by the Southeast U.S. Farm Press, the impacts of El Nino have already caused significant problems for farmers in some areas, yet helped produced a bumper crop in others.  Is help on the way? Perhaps, depending on where you live. Preliminary data reported by NASA suggests a possible weakening trend, but with Oceanic Heat Content anomalies still above 1.5 degrees C, the Climate Prediction Center reminds that effects of the current cycle will linger well into summer.

GREAT. WHAT ABOUT THIS WEEKEND?  The problem with being in an extreme cycle is that it can take a considerable period of time to rebalance.  Thus, the Forecast Team does not recommend you put away all the winter gear just yet in the Mid-Atlantic and Northeast. As recent as April 6-7, 2007 - some eastern cities saw measureable snow on Easter eggs and gave the bunny a chilly morning trip. We are watching for the potential of a shift in the cold regime from the central plains to the east, with the possibility of a chilly rain or brief overnight snow Friday into Saturday from Virginia through central Maryland to eastern Pennsylvania.
