If you had the poor judgment to purchase an open-air seat in the upper, upper grandstand (perhaps to be closer to the ebeshter in himmel), than you might bring along an umbrella, fleece-lined raincoat (checked for shatnes of course) and a big thermos of chulent (assuming you have a seat near the proper facilities). Otherwise, just rely upon the energy of your davening and tanzin to generate sufficient heat to melt the snow.
