Warmer & more humid through Fri. An isolated shower may move inland off the Atlantic Thu. otherwise the best chance for scattered showers & storms will be late Fri. as activity develops near the sea breeze close to I-95. A cold front that will produce lots of severe storms Thu. from Louisiana to Michigan will weaken as the front moves across the First Coast Sat. But there will still be lots of clouds & at least scattered showers from time to time. Temps. will be cooler Sat. then much cooler Sunday as brisk northeast winds blow off the chilly Atlantic water. Some light rain may still occur Sunday. So not a washout for the weekend but damp & -- by Sunday especially -- cool.
Arctic sea ice has started to melt albeit very slowly:
Utilizing NASA satellite images NSIDC says the total area Arctic Sea ice for this winter (2013) is the 6th lowest in our 30 years of satellite data. Click ** here ** for Sea Ice & Analysis.
The ice grew from a record low summer-size of 1.3 million square miles to total area of 5.84 million square miles.
(In other words, it went from one-third (1/3) the size of the lower 48 to almost twice (2x) the size of the US.)
This leaves much of the Arctic sea now only covered with thin 1 yr ice, which is likely to melt quickly as the days become longer and sun stays up longer.)

On March 15, 2013 Arctic sea ice likely reached its maximum extent for the year, at 15.13 million square kilometers (5.84 million square miles). The maximum extent was 733,000 square kilometers (283,000 square miles) below the 1979 to 2000 average of 15.86 million square kilometers (6.12 million square miles). The maximum occurred five days later than the 1979 to 2000 average date of March 10. The date of the maximum has varied considerably over the years, with the earliest maximum in the satellite record occurring as early as February 24 in 1996 and as late as April 2 in 2010.
This year’s maximum ice extent was the sixth lowest in the satellite record. The lowest maximum extent occurred in 2011. The ten lowest maximums in the satellite record have occurred in the last ten years, 2004 to 2013.
Over the 2012 to 2013 winter season, sea ice extent grew a record 11.72 million square kilometers (4.53 million square miles). The record growth was primarily a result of the record low minimum last September, leaving a greater extent of ocean surface uncovered in ice to re-freeze this winter. This seasonal ice gain is 645,000 square kilometers (249,000 square miles) higher than the previous record (2007 to 2008) and 2.63 million square kilometer (1.02 million square miles) higher than the 1979 to 2000 average. Last autumn’s record low and this winter’s record ice growth indicate a more pronounced seasonal cycle in Arctic sea ice and the increasing dominance of first-year ice in the Arctic.
