It’s not even Halloween yet, but western Maryland is under a Winter Weather Advisory tonight. At Garrett College in McHenry, the high temperature today was just 30F, the low so far 28F. The strong storm that tracked from the coast of New Jersey north into central New England has produced a strong northwest wind across all of the mid Atlantic region. This northwest flow of air is drawn down from the great lakes where the moisture laden air rides up the western slope of the mountains producing “lake effect” rain or snow, depending on the temperatures. With the cold air in place, the lake effect tonight will produce snow, possibly 3-5″ overnight on the highest ridges. The pictures posted here are from the Maryland State Highway Administration’s camera on Big Savage Mountain, elevation 2,454 feet. The first picture at 5:14pm Tuesday shows some snow on the grassy shoulders but just wet pavement. By 11:12pm Tuesday night, with the temperature at 29F, the snow is starting to stick to the road. The gusty winds and colder than normal air will continue to buffet Maryland on Wednesday and it’s even possible that a snowflake or two could cross the mountain ridges and arrive in the colder suburbs north and west of Baltimore. For those not ready for winter just yet, hang in there…sunny, milder weather is coming for Thursday and Friday.
