@high risk looks like LWX going 15:1 SLRs for tonight for DC metro

FXUS61 KLWX 101923 AFDLWX Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 223 PM EST Fri Jan 10 2025 .SYNOPSIS... Light to moderate snow will overspread the area as an area of low pressure tracks to the south tonight. High pressure builds back in for Sunday and Monday. A clipper type system may impact the Alleghenies Tuesday. && .NEAR TERM /THROUGH TONIGHT/... A quick hitting light to moderate snow event is expected across the area with most coming to an end by sunrise Saturday, aside for the Alleghenies... Synoptically, an elongated longwave upper trough digs into the Southeast US today. Guidance has been very consistent with taking an associated surface low south of our area and then off the coast of the Carolinas. With this track, the heaviest precipitation associated with this system will also fall to our south. A general inch or so of snow is expected for most of the area. However, there appears to be several areas of locally higher snowfall 1) The greater DC metro appears to be near the intersection of the nose of the low-level jet and edge of the moisture surge. Have issued a Winter Wx Advisory for this area given overall agreement on at least 0.1" QPF in this area. Given SLRs of 14 or 15:1 or so, this will result in a broad 1.5 inches. Advisory criteria is 2", which we feel is attainable in areas that are under the relatively speaking more robust bursts of snow. Regardless exact snowfall amounts (1, 1.5, or 2"), it will still be impactful given the cold ground surfaces. 2) Central VA into Southern MD. This area is moreso associated with the forcing of the low-level FGEN of the low pressure system. The area is on the northern edge of it, but a subtle enhancement appears likely. Have maintained a Winter Wx Advisory for this area. 3) The Alleghenies... have maintained a Winter Weather Advisory from through evening for yet another 2-4" of snow out there with up to 6" possible on the higher ridges. This area is in a favorable position of the synoptic UL jet (left exit region) which should yield a period of light to moderate snow tonight. Behind the system, upslope snow showers and gusty winds will continue. Considerably blowing and drifting snow is likely.

Winds kept the temps up again

Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 353 AM EST Fri Jan 10 2025 .SYNOPSIS... High pressure will build overhead today before sliding east. An area of low pressure will track to our south Friday night into Saturday bringing light snow to the area. High pressure will build back in for Sunday and Monday. && .NEAR TERM /THROUGH TONIGHT/... High pressure slides east today while an elongated upper trough digs into the Southeast US. A surface low pressure system will pull away from the Lower Mississippi Valley this morning and make its way into the Carolinas by this evening. The bulk of the snowfall associated with this system will stay to the south of our area and then off the coast of the Carolinas, in a favorable position of the synoptic UL jet (left exit region). The northern gradient of snow totals will likely be tight, and could shift a bit north or south depending on where the jet sets up. Winter Weather Advisories have been issued from tonight into Saturday morning for counties along our southern tier given fair confidence in around 2 inches of snow accumulation. More counties could be added if a northward shift of the jet seems more likely. Advisory level snow is likely for the Alleghenies where a Winter Weather Advisory remains for this evening through Saturday evening for an additional 2-4" of snow out there with up to 6" possible on the higher ridges. Behind the system, upslope snow showers and gusty winds will continue. Considerably blowing and drifting snow is likely. Elsewhere, confidence is increasing for light snow accumulation (1-1.5 inches) for most of the area Friday night into Saturday morning. The northern Shenandoah Valley is expected to get the least snow, in the shadow of the Alleghenies. Regardless of amount, fresh snow on top of the previous (and likely now icy in many spots) snowpack will require extra caution when out and about.

Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 222 PM EST Thu Jan 9 2025 .SYNOPSIS... High pressure will build overhead tonight into Friday. An area of low pressure will track to our south Friday night into Saturday bringing light snow to the area. High pressure will build back in for Sunday and Monday. && .NEAR TERM /THROUGH TONIGHT/... Aside from a few mountain snow showers across the Alleghenies, dry conditions are expected with sunny skies. Well below normal temperatures continue despite the sunshine as Arctic high pressure builds in. Have gone well below NBM guidance tonight across typical areas the radiate efficiently in high pressure given the snowpack across the region. Generally along/north of US-50/I-66 the winds area forecast to remain elevated. Therefore, temps are going to be warmer (relatively speaking) than those in the Shenandoah Valley and Culpeper area. Feels like temperatures will be several degrees above the air temperatures, but generally marginally above Cold Weather Advisory criteria. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... High pressure overhead will slide east Friday while an elongated longwave upper trough digs into the Southeast US. Guidance has been very consistent with taking an associated surface low south of our area and then off the coast of the Carolinas. With this track, the bulk of precipitation associated with this system will also fall to our south. However, there remains uncertainty with several features of the system as depicted by model guidance. What is certain, is advisory level snow is likely for the Alleghenies (have a Winter Weather Advisory from Friday evening through Saturday evening for yet another 2-4" of snow out there with up to 6" possible on the higher ridges). This area is in a favorable position of the synoptic UL jet (left exit region) which should yield a period of light to moderate snow Friday night. Behind the system, upslope snow showers and gusty winds will continue. Considerably blowing and drifting snow is likely. Elsewhere, confidence is increasing for light snow accumulation (1-2 inches) for most of the area Friday night into Saturday morning. Generally speaking, Nelson County, VA to St Mary`s County, MD has the best potential for 2-3" of snow (or slightly more depending on the northern extent of heavier banding). Winter Weather Advisories likely needed in subsequent shifts to cover this threat.

LWX calling for 1-2 inches in their morning AFD FXUS61 KLWX 090826 AFDLWX Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 326 AM EST Thu Jan 9 2025 .SYNOPSIS... Cyclonic flow will continue across the area through Thursday. High pressure will build overhead on Friday. An area of low pressure will track to our south Friday night into Saturday. High pressure will build back in for Sunday and Monday. && .NEAR TERM /THROUGH TONIGHT/... Upslope snow showers continue this morning along the Alleghenies, and Winter Storm Warnings/Winter Weather Advisories remain in effect until late this morning. Strong NW winds persist as well, and combined with temperatures in the teens and single digits in the mountains (including the Blue Ridge), sub- zero wind chills are expected through the day. Cold Weather Advisories remain in effect until mid-morning for apparent temperatures near 10-15 below zero. To the east of the mountains, dry conditions are expected with sunny skies. Cold temperatures continue despite the sunshine as Arctic high pressure builds in. High temperatures struggle to breach the freezing while wind chills sit in the teens and 20s. Lows tonight fall into the teens with single digit wind chills. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... High pressure overhead will slide east Friday while an elongated longwave upper trough digs into the Southeast US. Guidance has been very consistent with taking an associated surface low south of our area and then off the coast of the Carolinas. With this track, the bulk of precipitation associated with this system will also fall to our south. Confidence is increasing for light snow accumulation (1-2 inches) for most of the area Friday night into Saturday morning. Upslope snow could continue along the Alleghenies into Saturday afternoon/evening, totals closer to 2-4 inches. Temperatures remain in the 20s to low 30s across the area, so this will be in addition to any existing snowpack.

06z NAM increased qpf and snow amounts a bit

Good luck guys... hope you get a nice snowfall

Loudoun county changed to closed tomorrow "After further assessment of neighborhood roads and sidewalks this evening after sunset, we have determined that Loudoun County Public Schools will remain closed Thursday, January 9 due to additional freezing and icy conditions."
