Warm Nose

Just measured 0" on the snowboard)

Yep, lop off 25% from those juiced up maps and that's probably the target

I'm about a mile from the Blue Ridge at 800', so far Western Loudoun

Expecting 3" here, anything beyond that is a bonus.

Updated discussion from LWX. More of a re-read of the forecast than a discussion. .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... For the evening update, have refined timing of precip onset and changeover but did not change snow amounts. Have raised ice amounts west of I-95 Wednesday into Wednesday night based on latest guidance and trends. Additional winter weather headlines may be needed for this period especially west of US-15 and over northern MD. Otherwise, temperatures fall into the 20s to low 30s overnight. Cloud cover increases overnight as surface low pressure approaches from the south. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... A low pressure system will bring widespread snow to the area Tuesday afternoon through the overnight. Snow overspreads the area from southwest to northeast beginning Tuesday morning with snow reaching the metro areas in the early afternoon. A Winter Storm Warning is in effect for the areas along and south of I-66 and the Washington DC metros. For the warned areas, heavy snow is expected with total accumulations between 4-7 inches. Locally higher amounts up to 8 inches are possible along the highest ridges in the Blue Ridge and Allegheny mountains. Further north, Winter Weather Advisories are in effect for areas along the MD/PA border with snow accumulation between 3 and 6 inches expected. Ice accumulations up to a tenth of an inch are possible along and west of the Blue Ridge Tuesday through Tuesday night with the greatest chances being for those in the southern portions of the area. Precipitation lulls Wednesday morning for a few hours before another low pressure system brings another round of wintry precipitation to the area. Mixed precipitation is expected with the main threat being freezing rain beginning Wednesday afternoon. A light wintry mix is possible Wednesday morning into the midday, before a steadier wintry mix occurs late Wednesday afternoon into Wednesday night. Total snow accumulations up to 1 inch and ice accumulations around one quarter of an inch are possible with a Winter Storm Watch in effect for the Alleghenies and Blue Ridge. East of the Blue Ridge, temperatures will be above freezing with precipitation type likely remaining as rain throughout the day.

34/19 and definitely plummeting under clear skies.

Amazing that school bus technology has actually regressed in the last 40 years where they can no longer drive effectively in 2 inches of snow. Technological advances? Pffftt ....

3" seems to be the realistic outcome here for most. LWX discussion: .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... Heading into Tuesday, we have a favorable setup for a long duration of snow across the area. With a broad upper trough over the CONUS and a CAD wedge over the area with surface high pressure to our northeast, we`ll have a cold thermal profile in place and Gulf moisture streaming in aloft from the SW Tuesday and through midweek. Guidance has been trending later with this system, with precip now expected to begin mid-late Tuesday morning and overspread the area SW to NE through Tuesday night. Precip type is expected to be snow to start, with some sleet/freezing rain mixing in along our southern tier where temps rise through the day. There is some uncertainty regarding temperatures during the day Tuesday as the surface high to our northeast begins to erode. Precip type and accumulation will be dependent on these temperatures as well as precip rates. Currently, high temperatures are expected to top out in the mid 30s. While temperatures will be dropping Tuesday night after sunset, WAA aloft to expected to gradually erode the CAD wedge from south to north overnight. More sleet/freezing rain is expected to mix in as a result Tuesday night into Wednesday morning. Winter Storm Warnings and Watches are currently out for Tuesday and Tuesday night for expected snow totals of 3-5 inches, with locally higher amounts to 6-7 inches possible. Ice accumulation of around a tenth of an inch is possible along our southern tier. Further Warnings and Advisories may be issued today, so be sure to check weather.gov/lwx/winter for the latest information. As the initial disturbance moves offshore during the day Wednesday, a lull in precip is expected before a second disturbance approaches from the southwest. Precip type is expected to be more of a sleet/freezing rain mix than snow, before gradually turning over to rain through Wednesday afternoon. IP/ZR likely continue along and east of the ridges where cold air hangs on a bit longer.

You're looking at the Wednesday event. All of their snow falls on Tuesday and overnight. Yes, it's still overdone but this doesn't show that.

This has high bust potential written on it ... I suspect we'll see a lot of disappointed people in the Obs thread come Wed morning.

This is setting up for a classic letdown when folks expect 6-8 sub-wide. 3-5 for most is the bar, I think, and we should be very happy with that if it verifies.

Ya'll realize you be postin' on a troll model, right?

Given most of the Sub is 4"-8" 48 hours out, even when you cut the usual 20% totals hype from wishcasting that would still be a 3"-5" event. Take.

Agree, time to put a stake in January ...

Temperature inversion! 11 degrees while stations lower are 5, 3.

I think that meets 'BUST' criteria ...

RGEM yesterday. Honestly not too far off - the thermals wrecked things east of 15.

Down to 27 here now. Cleared the driveway with the snowblower but the pixie dust has made everything really crunchy.

To the Mets on the board, what's the post-mortem for this one? Seems once the front took more time it screwed up the thermals resulting in a bunch of wasted QPF, not to mention the QPF itself was less amped than predicted.
