Pretty sure you’re spot on. I believe Dulles began in the 60’s? Someone confirm. 1 Link to comment Share on other sites More sharing options...

WxUSAF Posted December 14, 2020 Share Posted December 14, 2020 WBAL had a pretty good map earlier, at least prior to any 12z/18z changes. I don't get just ripping the RPM snow map as a forecast. WJZ has this pretty terrible looking maps, but I guess 4-6" around Baltimore is reasonable. 1 Link to comment Share on other sites More sharing options...

SnowGolfBro Posted December 14, 2020 Share Posted December 14, 2020 If there is any hope left for the corridor, the 12z Euro did reduce ground temps by 3 degrees from 6z. If that holds or continues to trend colder at 18z. We have some life...until 0z Link to comment Share on other sites More sharing options...

Texts all day with "How much for". I made a long FB post today as I've been getting lots of questions from family and friends. 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. 13 Link to comment Share on other sites More sharing options...

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.
