I am predicting a high temperature of 62º Tuesday with more rain and showers...A Yellow Weather Alert Day.
-----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.
Each day we'll post the new guarantee, and Topper will share the results each night on WUSA9 at 11. Follow @TenaciousTopper on Twitter and Instagram for 'round the clock weather updates.
