Here it is for anyone who cares: Major winter storm for Maryland Wednesday into Thursday Snow will start late morning Wednesday from south to north across the state. It will mix with sleet, and possibly rain, for much of Maryland outside of northern Baltimore county to Frederick and points north. Sleet will eventually turn back to snow later in the evening Wednesday before tapering off early Thursday morning. The gradient between a little slush and snow to a LOT of snow is really sharp. Could be as little as ~20-30 miles in places. Picking that exact boundary is very difficult in advance. Elevation and latitude is critical. Higher elevation locations and locations farther north will get more snow, all else being equal. Numbers below include sleet, and there could be a lot of sleet in places. Howard county: 9-15" in Mt. Airy, 6-12" west Ellicott City, 4-8" Columbia, 2-5" eastern Elkridge. Harford county: 10-18" northwest, 6-12" Bel Air, 4-8" Abingdon, 3-6" Aberdeen and Havre de Grace. Baltimore city: 3-6" 495 beltway: 3-6" north side near Bethesda, 2-5" most elsewhere, 1-3" south side. DC: 2-5" north DC, 1-3" downtown.

Fozz Posted December 14, 2020 Share Posted December 14, 2020 6 minutes ago, WxUSAF said: Which is kind of the point. They had a forecast. Why stop using it for that garbage? P.S. Go RPM!! My best guess is because a lot more normies now talk about specific model runs whenever a snowstorm is on the way, especially since 2014. I guess social media encourages hype and it became an easy outlet to spread these kinds of maps to the masses. So as a result the local channels are catering to what the audience probably wants to see. Of course I don’t agree with TV mets doing this, but I guess it’s now good for business.

If you want to see the jackpot I would head up around Harrisburg, PA. But the nice thing about Winchester is you can be here from the city in an hour and a half once the roads are cleared.

Jebman Posted December 14, 2020 Share Posted December 14, 2020 This storm presents a resplendent opportunity to take a drive up Rt 28, north to Rt 7, over the Skyway to the West Bypass Rt 7 and on up to and over Rt 9, clear to the West Virginia State Line. You will see incredible gradations of increases in snow all along the way. Dale City will get plenty of snow, with maybe a little sleet, but if you choose to watch it from Charles Town West Virginia, it will present jebwalk prime conditions as close to 20 inches of the white gold pile up! 7 Link to comment Share on other sites More sharing options...

jayyy Posted December 14, 2020 Share Posted December 14, 2020 Very interested to see how things shape up around rt 108/70. Could have eastern ellicott city seeing 4-7”, as western ellicott city / Marriottsville sees 7-10” with more as you head out west / north. Very sharp cutoff coming indeed. Would love to see 18z start a slight tick SE for folks closer to 95 to get in on the action. I’d gladly sacrifice a few inches up this way for my friends right down by da beach (bay) Link to comment Share on other sites More sharing options...
