Appetizer wave #1 looking much healthier on the NAM

@Hoosier When its your winter - nature can seem very creative in finding ways to over-perform.

This clipper is not a normal mid winter clipper. Even though DSM is not going to get the heavier amounts- the flake size on the back side of this is quite impressive and something I don't recall in previous clippers. Picked up a solid .7" last hour in legit moderate snow - which at night is tough to do. (VIS 1/2) Good Luck to those N and E. I think it's going to over perform for many.

Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 811 PM CST Sat Dec 6 2025 .UPDATE... Issued at 811 PM CST Sat Dec 6 2025 Snowfall timing remains right on track, spreading across I-39 shortly (through 930 PM) then into Chicagoland 10-11 PM. No significant changes needed to PoP timing as a result. The main development this evening is a slight increase in the modeled 850 mb wind response overnight as a southwesterly low- level jet pushes east of the Mississippi River and briefly intensifies, with the latest iterations of the RAP and HRRR now consistently suggesting wind speeds pushing towards 35-40 kts. This mass response is a bit more significant than what has previously been modeled by global guidance, and suspect there may be some very modest upper jet/PV interaction at play based on latest model analyses. It`s still a bit unclear if this will fully be realized, particularly given the gradually rising surface pressures within the parent surface low across Kansas (slowly weakening), but the trends have been fairly persistent. The main result of this has been for a general sharpening and increase of the 925-800 mb frontogenesis, maximizing more-or- less right along the I-88 corridor overnight tonight into early Sunday morning. A commensurate increase in peak UVVs nearing 25 ubar/second within this area are evident, and while these maximum values do not perfectly overlap the depth of a somewhat narrow dendritic growth zone, they are strong enough that mean UVVs through the DGZ are advertised near 15+ ubar/second for a 3-5 hour window tonight which may help boost SLRs a bit. Given all of this, have slightly increased QPF and snowfall amounts in the vicinity of a Rochelle to Midway Airport line where peak hourly snowfall rates around or a hair above an inch per hour will be possible during a brief window late tonight. We`ll call it a general 3-6 inches in this area, with the highest amounts likely falling in a very narrow corridor, and a few totals beyond 6 inches can`t be ruled out. Finally, suspect there will be a serious snowfall gradient near and south of I-80, and likely greater than we can reasonably depict in the gridded forecast due to mesoscale subsidence on the south side of the main f-gen circulation. Don`t see a need for changes to the going Winter Weather Advisory configuration. There continues to be a potential for a little wintry mix/freezing rain at times south of the Kankakee River tonight, but temperatures will gradually warm to near or even locally just above freezing, likely mitigating impacts. Depending on how quickly winds come up Sunday morning, some blowing and low drifting of snow may occur, mainly in open/rural areas, so this is something we`ll be keeping an eye on. Finally, lake effect snow may focus across parts of Lake/Porter counties in NW Indiana Sunday afternoon before pivoting west towards NE Illinois/Chicago Sunday evening and overnight. Thermodynamic parameter space isn`t particularly robust or concerning, but some additional localized accumulations up to an inch or two may occur through this timeframe. Carlaw
