12z GFS 384 hr Kuchera snow map

Are you able to carry on a conversation with someone who has a different opinion then you (whether right or wrong) without calling them stupid or illiterate, now please go back into your basement and enjoy your day.

I am not but you might be!!!! You might want to look at the 12Z GFS compared to the old 6z GFS that you are referring to. I am not sure if you are smart enough to understand that the LOT forecast that you referring to was before the 6z run came out and believe it or not models do change from time to time. You my friend have a wonderful day and enjoy your 2-3 day Feb 17 redux!!!

are you talking about this

where?

Surprise snow last night about 1 inch

to bad the GFS doesnt go another 6 hours to 390 because

Feb average is 10.7 do we make it 4 months in a row?

GFS looks good for cyclone at 384 hours!!!!

ended up with just under 2 inches here for round 1 lake effect has moved back in prolly get another inch

great Ricky update from NWS As generally anticipated, the mid-level and surface trough axis configuration today is decidedly focusing lake effect snow banding near and on the west side of the lake. However, the intensity of the snow extending well north to offshore of Manitowoc, WI increases concern for bursts of moderate to heavy lake effect snow persisting into this evening for northeast Illinois. While this won`t be a continuous firehose of snow like in a single dominant intense band, webcams under the heavier snow rates have consistently shown roads quickly becoming snow covered/hazardous. With the previous advisory and watch configuration for central and southern Cook, there was some thought that there would be more defined breaks in the accumulating snow, which appears less likely at this point. Additionally on this note, comparing radar to recent HiRes simulations, the HRRR seems to have a better handle than the 12z NAMnest (which initialized too far east with the snow off the WI shore). This suggests the intense banding developing this evening has a better chance to impact eastern sections of Cook County (and possibly even Lake and northern Cook) before shifting into northwest Indiana tonight. Ultimately, we opted to just replace the previous advisory for central and southern Cook with a warning, in effect until midnight. Confidence isn`t super high in exact trends yet, but felt that localized 6"+ amounts appear quite likely (especially near the lake), and more importantly the significant impacts to travel due to periods of 1-2"/hour snow rates and visibility as low as 1/4 mile. We`re keeping a close eye on webcams and road conditions in Lake and northern Cook as well (Waukegan Airport 1/4 mile visibility as of this writing) for a possible need to upgrade these counties from an advisory to a warning. As the snow band(s) come ashore today, convective snow showers may spread fairly far inland into areas where broad light snow is ongoing underneath the mid/upper trough. Should it appear this activity is more potent, we may need to consider advisories for this, or at least Special Weather Statement issuance. The Winter Storm Warnings for Lake and Porter County Indiana remain unchanged for now. DuPage County IL is also in an advisory given the closer proximity to the lake of northeastern sections of the county, though again, confidence is on the lower side regarding how things will play out farther inland in the Chicago suburbs.

As per Mike Caplan The weather service upgrades central and southern Cook county to a winter storm warning. This will include the city of Chicago.

yep worded pretty poorly Central and Southern cook convert from an advisory to winter storm watch at 3pm?

Central Cook-Southern Cook- Including the cities of Chicago, Calumet City, La Grange, Oak Lawn, Lemont, Orland Park, Cicero, Oak Forest, Park Forest, and Oak Park 129 PM CST Thu Jan 29 2026 ...WINTER WEATHER ADVISORY IN EFFECT FROM 9 AM TO 3 PM CST FRIDAY... ...WINTER STORM WATCH IN EFFECT FROM FRIDAY AFTERNOON THROUGH LATE FRIDAY NIGHT... * WHAT...For the Winter Weather Advisory, snow expected. Total snow accumulations 2 to 3 inches, within a few hour period. For the Winter Storm Watch, heavy lake effect snow possible. Total snow accumulations locally in excess of 6 inches possible, mainly near Lake Michigan. * WHERE...Central Cook and Southern Cook Counties.

Florida will get snow before some in this sub forum

Chicago NWS on Lake Effect There has not been much change in the recent guidance. High pressure will build across the northern Plains Thursday night into Friday as an upper level low moves across the local area Friday into Friday night. This will setup convergence over Lake Michigan with a band of lake effect snow developing Thursday night, possibly into northwest IN at first, then spreading west into far northeast IL Friday morning, then moving back east into northwest IN Friday evening and then possibly moving back into northeast IL Saturday morning. While these overall trends remain on track, the earliest snow would begin is still 48+ hours away and while lake effect is challenging, there can be even more uncertainty when its pointed into northeast IL. While it remains a bit early for specifics, if a lake effect band does develop, periods of heavy snow will be possible across far northwest IN and far northeast IL with several inches of snow possible.

Alek= Lake effect king

what did u end up with yesterday

GFS had no snow in chicago where over 6 inches of lake induced/lake effect has happened so far.

Izzi Lake enhanced snow has overperformed overnight with totals of 4-7" observed near Lake Michigan in Cook County. Snow to liquid ratios have been on the order of 25-40:1 with the lake enhanced snow. Guidance depicts a strengthening low level convergence axis this morning with similar moisture and instability profiles, which would favor a consolidation from a multibanded structure to a single band or two of more intense lake enhanced snow. Given the expectation that heavy lake enhanced snowfall with rates around or just over an inch per hour will continue across Cook County the remainder of the morning and into at least the early afternoon, opted to upgrade Cook County to a winter storm warning. Additional snowfall of 2-5" seems likely near the lake, which on top of the already 4-7" that has fallen should leave snowfall totals near the lake in the 6-12" range.

Additional snow accumulations 2 to 5 inches, heaviest near Lake Michigan. Storm total snowfall ranging 2 to 4 inches northwestern Cook County to 6 to 12 inches near the lake. Snowfall rates around 1 inch per hour are expected with the more intense lake effect snow bands. * WHERE...Central Cook, Northern Cook, and Southern Cook Counties

yep it comes in waves snows hard for a bit and then nothing

looks to me that the Milwaukee Lake effect band is now reached Waukegan and will merge with the Lake enhancement of southern Lake and Cook County.

Chicago NWS update With increasing low-level convergence forced by stronger easterly flow through the night, would have to think that the lake effect snow band should have more success moving inland with time, even if just for a few miles. Based on the current trajectory and west/northwestward drift of the snow band, areas near and north of Evanston appear most in line to see the lake effect snow overnight. After daybreak, the expectation is for the snow band to pivot back southeastward across northeastern Illinois during the morning hours and into northwestern Indiana during the afternoon as the low-level wind field backs along the backside of the departing storm system.
