WHY DON’T WE GET “BAY EFFECT” SNOW IN MD? The simple answer - TopicsExpress



          

WHY DON’T WE GET “BAY EFFECT” SNOW IN MD? The simple answer is: the Bay is not wide enough. It’s only about 4 or 5 miles across. Lake Erie, for example, is 40 to 50 miles wide. Lake effect snow is created by the atmospheric instability induced by cold air moving over the warmer lake waters. Cold air over warm air causes rising motions in the atmosphere (instability), and that gets the snow going. The Chesapeake Bay does not have enough surface area (fetch) to allow that process to take place. If the Bay was wider, the Eastern Shore of MD would often get pounded with Bay Effect heavy snow bands. :) Thus ends today’s weather geek session.
