Herbie conditions will continue to subside through the day but leave lingering ceilings through tomorrow morning where they will finally scatter out. Marginal ceilings and reduced visibility due to snow are possible Monday afternoon into the evening as a new system sets up in the Ross Sea. Midday Tuesday we see the next system drive a trough through McMurdo, bringing back Herbie conditions through midday Wednesday. Once again, it appears marginal ceilings may linger in the wake of the Herbie. Cheers, Joey Snarski
