Gimme gimme

12z UKIE is nice through 72...

He was saying better than 10:1... probably more like 14:1

This is the 00z UKIE run... but it is 10:1 SR

Sure it was posted already earlier, but 00z UKIE was nice as well

Looks like 2-4 i66 corridor... 4 to 8 in MD on 12z CMC

https://collaboration.cmc.ec.gc.ca/cmc/cmdn/pcpn_type/pcpn_type_gem_reg.html Out to 90

I'll take some 12z CMC to go please

Fringed But I wouldn't mind another 2-4. I'd like more... but that's good for me

That's not good

BTW... 20:1 SLRs? Wow

Upgrades maybe? Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 326 PM EST Mon Jan 15 2024 .SYNOPSIS... Low pressure sliding to our south will bring widespread light to moderate snow to the region. The low pressure system will slide off the Delmarva coast Tuesday morning with arctic high pressure building in. Dry and cold conditions are expected midweek before another wave of low pressure and front approach Friday. && .NEAR TERM /THROUGH TUESDAY/... Snow will continue to pick up in intensity while overspreading the area from the south and west this afternoon. This is in response to a strong wave of low pressure ejecting out of the Tennessee River Valley and into the central Appalachians later this evening and into the overnight hours. The strongest lift with this system looks to arrive between 6pm-2am. This is when most of the area could see a period of moderate snow. Current 12z HREF guidance continues to hold on a general 3 to 5 inches of snow across much of northern/central MD and northern VA with even a few members hinting at amounts of 6"+ across northern portions of Frederick, Baltimore, Carroll, Harford, and Cecil counties (in the favored climo/Parrs Ridge zone). Elsewhere, a general 2-4 inches of snow is likely across much of the Shenandoah Valley, central VA, and southern MD. Some freezing rain may mix in on the tail end of the system across central VA and southern MD with warmer air trying to work in as it departs Tuesday. Winter Weather Advisories remain in effect for the aforementioned threats above. These advisories may need to be re- evaluated especially with forecast snow to liquid ratios running as high as 20:1 during the period of strongest upward motion this evening into the front half of the overnight hours. Mountain locations will see a touch more snow with accumulations ranging between 4 to 8 inches along and west of the Allegheny Front. This is due to the added lift from the terrain plus upslope component that looks to keep snow going through early Tuesday afternoon. Highest snow amounts look to be from Keysers Ridge south along Backbone Mountain and down toward Spruce Knob, WV where Winter Storm Warnings remain in effect. High temperatures will range from the teens over the mountains to upper 20s across most of the region. Lows will be quite similar overnight in the mid to upper 20s areawide outside the mountains. Low pressure will continue to lift north and east of the Delmarva coast Tuesday morning. Some light snow may linger over northern MD through mid-morning with upslope snow showers set to continue in northwest flow over the mountains through Tuesday afternoon. Highs Tuesday will range between the teens over the mountains to mid to upper 30s south/east of I-95.

Well shit... guess we're all fucked (no I didn't edit it at all... go read the afternoon AFD from LWX just issued and you'll see it yourself) Precipitation chances overspread the area overnight Thursday into Friday as model guidance indicates an area of low pressure developing and travelling up the east coast. With high temperatures forecast in the low to mid 300s for most (teens and 20s at higher elevations), any precipitation will be snow. We will continue to monitor this event as it gets closer in time. As the aforementioned upper level trough pivots out of the area, upper level ridging and high pressure at the surface build over the area. Upslope snow showers continue through Saturday afternoon along and west of the Alleghenies with dry conditions expected elsewhere through Sunday. Saturday will be the coolest day of the long term period with highs staying in the 20s for most. Those in metro areas or located near the Chesapeake Bay will get into the low 30s while higher elevations dip into the low teens.
