The weather of the Mid-Atlantic’s future

The massive Federal review of climate change trends and projections released today documents a warming Mid-Atlantic that will grow warmer in the coming decades.  Along with soaring temperatures, we can expect more intense downpours, higher seas and stronger hurricanes, the report says. How intense these changes become depends on whether human emissions of greenhouse gases slow or continue unabated, the report stresses.
“…the majority of Maryland and Delaware, and southwestern West Virginia and New Jersey, are projected by mid-century to experience more than 60 additional days per year above 90°F compared to the end of last century under continued increases in emissions”

 Via the report: "Projected increase in the number of days per year with a maximum temperature greater than 90°F averaged between 2041 and 2070, compared to 1971-2000, assuming continued increases in global emissions (A2) and substantial reductions in future emissions (B1)."








“The frequency, intensity, and duration of cold air outbreaks is expected to decrease as the century progresses, although some research suggests that loss of Arctic sea ice could indirectly reduce this trend by modifying the jet stream and mid-latitude weather patterns.”

Via the report: "Projected average number of days per year with temperatures less than 32°F for 2041-2070 compared to 1971-2000, assuming emissions continue to grow (A2 scenario). Patterns are similar, but less pronounced, assuming a reduced emissions scenario (B1)."http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2014/05/06/national-climate-assessment-the-weather-of-the-mid-atlantics-future/
