This morning’s marine layer disintegrated, clouds scoured, and we were treated to an amazing afternoon with pristine skies and temperatures in the upper 60s. After some crisp overnight hours, Friday promises to be another stunning day.

Through Tonight: It’s mostly clear and pleasantly cool this evening, as temperatures fall back through the 60s and into the 50s.  By dawn, the entire region dips into the 40s with low 40s in the cooler suburbs and upper 40s downtown.  Some low and mid-level cloudiness could develop by morning, especially east of the District.

Tomorrow (Friday): Let’s call for a 20-40 percent chance of some early-to-mid morning low clouds with the highest odds east of the District.  Then it becomes mostly sunny and gorgeous with highs in the inviting mid-to-upper 60s.  Winds are from the east around 10 mph.

Record low tornado activity in last 12 months: Harold Brooks of the National Weather Service’s Storm Prediction Center reports just 197 tornadoes of intensity EF-1 or higher touched down nationally in the 12 months between May 2012 and April 2013 (the next lowest number is 247 between June 1991 and May 1992), the lowest such number since reliable records began in 1954.

Tornado fatalities have also been historically low.  Only 7 people died from tornadoes during this stretch – the fewest number in a 12-month period since just 5 died between September 1899 and August 1900.
