29. If the same area of low pressure has hung around for 2 months, that would be big news
Fri Mar 29, 2013, 11:08 AM
Mar 2013

It would be far bigger news than anything else in this thread. And it's not the same, as we can see by examining some weather in February:

Late on February 7, 2013, the low pressure area that would eventually develop into the February 2013 Nor'easter had a minimum pressure of 1008 mbar (hPa; 29.71 inHg), and was located over northern Florida, while moving northeastward.[28] At the same time, another low pressure area with a minimum pressure of 1011 mbar (hPa; 29.86 inHg) was located over northeast Illinois, moving to the east over the Great Lakes region, producing several inches of snow in the Great Lakes and in Canada.[29] Between 4:00 p.m. and 7:00 p.m. EST on February 7, the northern low had merged with a secondary low in the same area, and had intensified to 1009 mbar (hPa; 29.80 inHg)[30] By 7:00 a.m. the next day, the southern low had moved over North Carolina and was rapidly intensifying. It contained a large area of precipitation that produced heavy, flooding rainfall across the Southeast and Mid-Atlantic states, and extended into New England.[31] The southern system moved to the north-northeast, and was offshore New Jersey by 4:00 p.m. on February 8.[32] The two systems merged off the Northeast coast between 4:00 p.m. and 10:00 p.m. EST on February 8,[33] resulting in heavy snow for much of New England, particularly in southern and eastern New England.

On the afternoon of February 9, as the storm was departing New England and moving toward Nova Scotia, the structure of the extratropical storm on satellite imagery resembled that of a tropical cyclone with a well-defined eye-like feature while located east of Cape Cod.[34]

The cyclonic eye dissipated on the morning of February 10, while the nor'easter was moving out to sea. Later, the nor'easter passed just south of Greenland. During the next several days, the system continued moving eastwards toward the British Isles while weakening, and eventually left the GOES-East satellite covered region. The nor'easter reorganized while it was south of Iceland, and affected the UK and the Republic of Ireland from February 15 to 18.[35] After affecting the UK, the storm became indistinguishable, while turning northeastwards. Late on February 20, the remnants of the February 2013 Nor'easter were absorbed by a more powerful extratropical cyclone to the north.

North Atlantic weather systems generally cross it from west to east in a couple of weeks, while drifting north, like that one. The one from late January will not the one there now.
