About time for warmer air

Posted: 14 Feb 2011 05:47 AM

Wow, after being stuck in winter for a period seeming like forever, the warmer air this past weekend sure felt nice and makes spring feel like it is not that far away. The featured chart presents the climatology of when the first occurrence of a temperature happens in the new year. The blue line can be thought of the earliest a given temperature has been observed and the red line would be the latest we have waited for a given temperature in a given year. The green line is the average date of the first observation. So for mid February, we'd expect to have seen at least one day in the lower 50s after 1 January. The turquoise line shows the pain that occurred last year when we had to wait until March to see a temperature above 40.

Good = 30
Bad = 4
