Tenacious Topper's 3 Degree Guarantee

Every night at 11 PM on WUSA 9 news Tenacious Topper has the 3 Degreeº Guarantee.

I am predicting a high temperature of 38° Wednesday with some moderate to heavy snow, good enough for a Yellow Weather Alert.

-----Topper Shutt is rated as the most accurate weather forecaster in Washington, D.C.

Don't believe the data? He's backing it up by providing a daily '3 Degree Guarantee' of the high temperatures at Reagan National Airport.
