jayyy Posted February 28, 2019 Share Posted February 28, 2019 Very much liking what I’m seeing for central Maryland west and nw of Baltimore. Consistent with 2-4” on tonight’s models for Howard county and northern MoCo rgem is likely overdone per usual. I typically go with 2/3 of what it spits out. NAM RGEM and euro all seem to be pointing to central md getting a decent event. DC is in and out of jack, but I assume we’ll have a better idea by 12z tomorrow 1 Link to comment Share on other sites More sharing options...

Late season climo helps juice things up. That said... rgem is prob too aggressive but the NAMs work fine for my yard. I'd really like to break 30" this season, 6 Link to comment Share on other sites More sharing options...
clskinsfan Posted February 28, 2019 Share Posted February 28, 2019 Models continuing the trend this winter to juice up as we approach an event. I dont ever remember a winter where that has happened so consistently. 4 Link to comment Share on other sites More sharing options...

MillvilleWx Posted February 28, 2019 Share Posted February 28, 2019 Hey everyone. Been insanely busy with my radar certification. Been an absolute blast, but my god is it a lot to take in. These last two days going to wear me out. Anywho. Finally took the chance to look into this event. Looks like a good consensus building overall. One thing I’ve noticed is a slightly stronger vort moving into the area with a better diffluent signature leading into the start. Could see some solid banding structures during the storm height with 1”/hr rates plausible. 2-4” is looking real solid, but 4-6” is at play with the favored area north of I-70. Wouldn’t rule out the areas south of I-70 that climatologically have favor. That’s my guess for now. Hope I see some cool pictures on Friday. This is about the height of my input for the storm. Good luck, and hope to have a lot more to talk about with what’s down the pipe. . 14 3 Link to comment Share on other sites More sharing options...

Snow will develop tonight and continue into early Friday morning before tapering off after sunrise. The snow will mix with sleet early Friday morning. Accumulations are forecast to range from 1 to 2 inches along the I-66 corridor, to 2 to 4 inches north of Washington DC. The highest amounts will likely occur across northern Loudon, Montgomery, and Frederick Counties. The greatest threat for impact from this snowfall during the Friday morning rush hour will be north of the Capital Beltway Interstate 495. If you plan on commuting Friday morning, be aware of the potential for travel disruptions. Plan ahead by allowing for extra travel time, and consider using public transportation and telework options. Stay tuned for future updates on this winter weather event, and the potential for Winter Weather Advisories to be issued later today. Link to comment Share on other sites More sharing options...
showmethesnow Posted February 28, 2019 Share Posted February 28, 2019 Overnight Euro and EPS have shifted north with the strip of max snowfall as well as juiced up somewhat. Euro places the max strip just north of the PA line but now also shows a weaker secondary max strip developing just west of Balt and running east. Kuchera is below and runs to 2pm. We do see more snow afterwards into Sat, especially the northern tier but that is more in response to the developing coastal. Little late in the game for the EPS but it does favor the max strip (2 1/2") setting up farther south from the PA line down through Balt. The control though favors the op run. 1 Link to comment Share on other sites More sharing options...
showmethesnow Posted February 28, 2019 Share Posted February 28, 2019 The latest 12K NAM has cut back on the snow totals from its previous run through 2 pm Friday. Shows two maxes setting up with one running just south of DC and the other on the PA line. Maxes are generally 3-4 inches with some pockets of 4+ embedded. Between these two maxes (Balt/DC) we are seeing 1 1/2 to 2 1/2 inches. These are snowfall totals given at 10:1. Ground truth maps (+ snow depth) are uninspiring to say the least with 1" showing only on the PA line. Don't particularly like these maps because I find they can be just as misleading as the 10:1. Ground truth would probably between these two and I would favor more so towards the 10-1 especially for the northern tier. 3k has cut back as well and is generally showing 1 1/2 to 3 inches with some heavier pockets from Dc north to the PA line. What is interesting to note in that the NAMs are now starting to pick up on some coastal influences late Friday into Saturday morning in particular the 12K. Still we are outside the 48 hr envelop I normally draw the line before I take them too seriously. That said, I still think that period of time has potential to surprise. eta: 06Z GFS sends the max strip DC/Balt. We are generally talking 3-5" on the 10:1 through the whole region. Pos depth chart has a more realistic depiction then the on the NAMs with roughly 2 1/2 to 3 1/2 inches for the DC/Balt corridor. GFS is also getting somewhat aggressive with coastal influences for Friday night/early Sat. 1 Link to comment Share on other sites More sharing options...

It would be helpful if whatever coastal forms Friday heads into the 50/50 position to lower heights behind it for Sunday/Monday. As there is no hp damming to the north. Without that the cities are looking at more rain than snow. NW tier does ok. My 2 cents. Link to comment Share on other sites More sharing options...
