DDweatherman Posted December 15, 2020 Share Posted December 15, 2020 RGEM moved the snow line 40-50 miles SE for everyone on this run. A better 4-6" thump for those around the DC beltway just referencing TTB with better totals to the N/E. 4 Link to comment Share on other sites More sharing options...

Good 4-6” front thump then 4-8” back. Go with the 3k. Link to comment Share on other sites More sharing options...

It has colors and numbers overlaying a depiction of the states along part of the eastern seaboard. Some of the numbers and colors mean things. For instance, Canada is cold while the Atlantic waters are warm. 2 7 1 Link to comment Share on other sites More sharing options...

WTH is up with that donut of localized min sitting directly on top of me? I can throw a rock from my porch and hit 6" more snow in any direction. It literally trolls me.

ers-wxman1 Posted December 15, 2020 Share Posted December 15, 2020 Our best shot for heavy snow outside the favored areas well north and west will come on the front end thump. The CAD unfortunately is marginal and not deep which will erode quickly after 18z. Some areas such as nova, central MD, north of 70 could pick up 3-5 in the first 3-4 hours of the event before changing to sleet then rain. Need the thump. Wrap around CAA never set in stone and it appears the best forcing per the upper low energy will be north of the area in PA/NJ. Lighter snow on the backside for our area, let’s hope we can keep more forcing before everything shifts out. 2 1 Link to comment Share on other sites More sharing options...

It can run on a Windows 98 laptop I bet. maybe NCEP's license key to Excel expired so they can't run it. 2 Link to comment Share on other sites More sharing options...

Def think the RGEM is a little farther to the east, hence the “colder” temps. Probably not by a lot but we don’t need much to improve things.
