Our first winter event is looking likely for Thursday beginning just before sunrise and continuing through the morning with a mix of snow, sleet, and freezing rain. This does look to adversely impact travel and schedules for at least Thursday morning.
Presently, a storm system is expected to move north Wednesday night along the western Appalachian range, which puts us on the warm side of the system. However, strong high pressure to the north will keep cold air east of the mountains trapped at the surface setting up a mixed bag scenario. As the storm to our west weakens, a new storm will form along the Atlantic seaboard. The further south that storm develops, the greater potential for a prolonged frozen event here in central MD. Right now, the new storm is modeled to form too far north to keep us frozen throughout the entire day Thursday, but I’ll update periodically as the short-range models are becoming in range.
For now, an impactful winter event is likely Thursday morning from about 6AM until at least mid-morning. I’ll update this evening.
