Predict the number of 90+ days in Washington, D.C. coming this summer

With temperatures struggling to reach 60 today and frost advisories and freeze warnings in effect for D.C.’s north and west suburbs, 90+ days may be the last thing on your mind. But trust me, they're coming.

The average year at Reagan National (from 1981-2010) has 36 days at or above 90, including two during May. 2010 and 1980, which had 67, are the record holders for most 90+ days. Last year (2011), we had a lofty 50. As recently as 2004, though, we had one of our lowest 90+ tallies on record, with a lowly 11.

We will recognize the top forecasters in October (as we did for our winter snow prediction game last week).
