ExtremeWether2015BLooking back at the extreme weather in Baltimore of 2015, it started and ended with records. We tend to have short term memories with weather, so I like to plot the stats and take a step back for a quick comparison. The first thing that stands out is that we had two extreme months and they seem to almost completely balance each other.

Both February and December had the same number of eight temperature records, but on the cold and warm extreme respectively. February had four record cold lows (min) temps and four record cold afternoon (max) temps. December also had eight records, but on the warm end. This included 5 record daily highs and three warm overnight lows (min temps).

February was -10.5°F BELOW Average

December was  +12.3°F ABOVE Average

While the recent focus has been on the heat thanks in large part to El Nino, so it is easy to forget about the ‘Polar Vortex’ two winters ago, and the extreme weather on the cold side last winter. But also, check this post out about the 2014 Summer Without a Summer that had 5 cold records set in July alone that year.

I know I am missing out on some other weather events of 2015, even prior to the El Nino influence. This post is a focus on the most extreme weather. Here’s a more detailed breakdown of these three months:
