Which weather station shows the highest relative humidity?

Will lake effect snow likely develop if the lake is frozen?

Erie, Pennsylvania, experiences lake-effect snow in the fall when cold winds from the northwest move across warmer lake water. The air absorbs water vapor from the lake and then deposits it as snow to the east and southeast of the lake. During some winters, the surface of Lake Erie freezes solid. Which statement describes how this event would most likely change lake-effect snow in Erie, Pennsylvania?
