This was so close to being an amazing snowstorm for my part of the city. Think it was 2007? But we had a sleet storm that in all my years nothing has come close to. Think we had over 4 inches of sleet. It would have been somewhat enjoyable except for the fact I spent the whole time praying for a flip back as well as calculating how much snow it could have been.

Yeah - feb 2007 was what I was referencing that those who have lived here longer always cite. I don't know if this is like that for this area, but it's a lot of sleet at this point. I think that system was one of the top analogs for this storm actually... Link to comment Share on other sites More sharing options...

Eskimo Joe Posted March 14, 2017 Share Posted March 14, 2017 Some of our DOT cams are showing snow trying to mix back in up county (Barnesville, Hyattstown, Damascus). Not sure if anyone from the board that lives there is on right now...a ground truth report would be beneficial. Link to comment Share on other sites More sharing options...
Jebman Posted March 14, 2017 Share Posted March 14, 2017 I went for a short jebwalk. Raw cold rain is falling, but there is a lot of ice too. This rain is freezing on stuff. I have a quarter inch of ice on my car. There is 1 to 2 inches of sleet on roads, topped by ice. many objects are encased in ice. Its 28 degrees and ZR is still falling.

Kleimax Posted March 14, 2017 Share Posted March 14, 2017 27, Sleet and a little bit of ZR here in Owings Mills. Very light glaze of ice on the sides of cars and a tiny bit on branches Link to comment Share on other sites More sharing options...
snjókoma Posted March 14, 2017 Share Posted March 14, 2017 For the talk of ZR I don't see any glaze and it looks like 100%sleet to me. I have about 3" of snow/sleet right now. Link to comment Share on other sites More sharing options...

Maybe it was from earlier as the snow melted on cars and trees initially it created little drops of water that froze as it got colder Link to comment Share on other sites More sharing options...

IF the HRRR is right and that is a big if. The heavy rates that it keeps popping up for you in the coming hours would hopefully mean a much quicker flip over as that would be better able to overcome any warm layer. At this point it looks that what is holding you back are the 850's that are at +1 for a duration. So I would think you are definitely in the game if the models are just off a bit in that regards.

snjókoma Posted March 14, 2017 Share Posted March 14, 2017 I remeasured and got an average of about 2.75... 4" has probably fallen. If we do pull off a fluffy inch or two later, its gonna be a weird snowpack. Link to comment Share on other sites More sharing options...

Ltrain Posted March 14, 2017 Share Posted March 14, 2017 Well I was above freezing for about an hour but now I'm right at or just below freezing again because the rain is now back to freezing rain and the melting has stopped. Hopefully that's a sign of things to come and we will see some snow within the next couple of hours. Link to comment Share on other sites More sharing options...

snjókoma Posted March 14, 2017 Share Posted March 14, 2017 Mesoscale Discussion 0292 NWS Storm Prediction Center Norman OK 0222 AM CDT Tue Mar 14 2017 Areas affected...Northern portions of VA/MD...eastern PA...northern NJ...southern NY into southern New England Concerning...Heavy snow Valid 140722Z - 141215Z SUMMARY...Increasingly heavy snow will develop north/northeastward through the early/mid morning hours. Snow rates in excess of 1-2 in/hr will become increasingly common, with some embedded higher rates likely, especially toward sunrise and beyond across eastern/south-central PA, northern NJ, and much of southern NY and nearby CT/MA. DISCUSSION...A gradual phasing of dual upstream shortwave troughs will occur today while pronounced upward vertical motion spreads generally northeastward across the region this morning in concert with an increasingly coupled upper jet structure and a near-coastal warm conveyor. Latest surface analysis features around a 1000 mb surface low near the northeast NC coast as of 07Z (3AM EDT). To the north, considerable pressure falls of 4-5 mb/2 hours are maximized roughly along the I-95 corridor and immediate coast of the mid-Atlantic/Northeast, which is observationally consistent with he intense cyclogenesis expected over the next 6-12 hours (and beyond) northward along the coast. As cyclogenesis continues to occur, observations/short-term guidance are suggestive that the surface wet-bulb zero line will continue to slowly transition northward across parts of DE/NJ toward the NYC metro. This is suggestive of a more transitional/mixed precipitation type along the I-95 corridor. A longer duration of heavy-snow-optimal profiles, attributable to increasing lift coincident with a deep/saturated dendritic layer, are expected just west/northwest of the I-95 corridor from northern parts of VA and MD into south-central/eastern PA, northern NJ, much of southern NY, and eventually nearby CT/MA through 12-15Z. Lift/saturation aside, consistent with earlier 00Z observed soundings from Washington-Dulles and Wallops Island VA, various short-term forecast soundings suggest that very weak elevated buoyancy will continue to exist along the coast as mid-level lapse rates continue to steepen over the mid-Atlantic region. In the presence of increasing mid-level frontogenetical forcing, this is likely to contribute to increasingly organized/intense bands of snow and enhanced snowfall rates through the mid-morning hours, including some possibility for a few localized instances of thundersnow.

WHICH IS WELL WEST OF THE BULK OF THE GUIDANCE FROM 24 HRS AGO AND REMAINS JUST WEST OF THE 00Z CYCLE OF MODELS. THIS WESTWARD SHIFT IN THE INITIAL TRACK OF THE STORM MEANS A TREMENDOUS ATLANTIC SURGE OF MOISTURE/WARM AIR AND MAJOR PTYPE VARITIES OVER THE MID-ATL REGION. THUS TREMENDOUS WIDESPREAD BRIGHT BANDING HAS SHOWN UP ON RADAR TRANSITIONING THE EVENT NEAR THE DELMARVA FROM A SNOW EVENT TO MORE OF A SLEET STORM WITH SNOW FARTHER INLAND AND NORTH AND WEST. THUS AS THE INTENSIFYING LOW DRIVES UP THE COAST... HOW WILL THIS IMPACT THE REST OF I95 CORRIDOR FROM PHL TO BOS. THE FORECAST CONFIDENCE IS SHIFTING TOWARDS WIDESPREAD MODERATE TO HEAVY SNOWS TO PORTIONS OF THE INTERIOR AND A BRUSH FOR THE MAJOR MARKETS. Damn, that's such a gut punch for PHL, NYC and maybe BOS. We kinda knew to expect it here, they didn't. I still think NYC may come out better tho Link to comment Share on other sites More sharing options...
