Not that I buy that map, but at least we are lining up the bulk of this during the overnight hours (bad for viewing purposes though haha). Every half degree or whole degree helps, and it's nice to take any daytime assist to temps out of the equation. Link to comment Share on other sites More sharing options...

Kaner88 Posted November 25, 2018 Share Posted November 25, 2018 Snow seems to be intensifying a bit. Gonna need things to fill in pretty quick here otherwise us ORD-area folks might get pushed out of the fun for a bit, per radar Link to comment Share on other sites More sharing options...

Hoosier Posted November 25, 2018 Share Posted November 25, 2018 Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 235 PM CST Sun Nov 25 2018 .SHORT TERM... 233 PM CST Through Monday... A bit higher based frontogenesis on the nose of strong lower level warm advection is driving a band of snow/sleet along and north of I-88 this afternoon. Outside of the corridor of this band, precipitation is largely rain, but the intense nature of the forcing is driving a changeover to sleet/snow, and accumulations have begun largely along and north of I-88. Expect accumulations to continue across our far northern tier of counties this afternoon, with accums likely to ramp down for areas farther south as warmer air pushes in the and precipitation shield eases in these areas. Webcams across Rockford indicate how rapidly things will decline across the area as the more widespread precipitation shield arrives and rates overcome the warmer low levels easily. The lower level frontogenetical signature will strengthen later today and this evening and therefore expect a significant ramp up in precipitation late this afternoon and evening. Low pressure is currently across south central Missouri and still strengthening just ahead of an impressive upper trough in the region. After a brief lull in action this afternoon for areas outside of the snow band, expect a significant ramp up in winter impacts. Winds are increasing out the northeast ahead of the deepening low. Thunder has been reported out ahead of this system in an area of 7+ deg/km of mid level lapse rates across central Illinois. Warm advection ahead of the system will significantly ramp up also, and expect a blossoming precipitation shield here with time. Areas along and southeast of I-55 are still quite mild, and the precipitation will begin as rain in these area. Without belaboring the details of the storm, changes we have noted largely still fit our message that precipitation will transition to all snow across the area through the evening hours, likely in the 6pm-9pm across the Chicago metro, longer for areas southeast of this. Ensemble guidance has been trending toward increased confidence in the 1-2" per hour snowfall rates, and blizzard conditions for at least a portion of the area. These conditions will begin to set in across our I-39 corridor as early as evening, with the mid evening and overnight hours being prime-time as head toward Chicago. From the earlier update: Regarding headlines, the low track being just a bit south based on observations suggest a swath of fairly strong winds being coincident with heavy snowfall this evening. We tried to highlight the area that has the best overlap of 1-2" per hour rate potential combined with the strong winds for a longer period of time for the upgrade to Blizzard Warning. The strongest winds may actually setup across LaSalle/Livingston counties where rates may be a tad lower, meanwhile Winnebago will still get good snow rates but be a bit more removed from the strongest winds. Therefore near blizzard/occasional whiteout conditions remain possible in these areas, but at this point the Ogle/Lee/Kane/LaSalle/DeKalb corridor is really in a sweet spot. This is not to say we cannot rule out neighboring counties such as Dupage/Will/Winnebago are out of the woods, and these counties could be considered as the storm approaches. Cook county is a challenge as the strongest winds will be at the lakefront where snowfall accums/rates will be reduced initially due to the warmer low level temperatures, but northwest Cook County is a concerning area too. But the message does not change: Conditions will rapidly deteriorate tonight with very heavy snow and strong winds creating life threatening conditions which could make travel nearly impossible in some locations. This includes the counties that border the current Blizzard Warning areas. Meanwhile, strong winds at the lakefront will likely lead to some lakeshore flooding as very strong winds build waves that will batter the shore. Model guidance suggest that the heaviest snow will wind down during the beginning of the rush hour, but gusty northwest winds will continue with some lighter snows closer to the IL/IN stateline and across Chicago, some impacts are likely to continue before the precip shield shifts east.

Going to be insane when this gets cranking I noticed last night the models had us get into a little dry slot as the fronto band lifted north. For awhile this morning I was starting to think the fronto band might not make it as far north as it did. Basically what the guidance last night was showing ended up being correct. I will say this, that was a loooooong hour and a half lol. Glad to be back in the precip again. Link to comment Share on other sites More sharing options...
Harry Perry Posted November 25, 2018 Share Posted November 25, 2018 Area Forecast Discussion National Weather Service Grand Rapids MI 316 PM EST Sun Nov 25 2018 LATEST UPDATE... Synopsis/Discussion/Marine .SYNOPSIS... Issued at 316 PM EST Sun Nov 25 2018 - No big changes to the going forecast. - The snow will be disruptive, but not crippling, thus we kept the Winter Weather Advisory and did not upgrade to a Winter Storm Warning. - Monday morning commute will be much slower than normal. - Confidence still high on a plowable snow. - Heaviest snow between I-94 and I-96 where 5 to 7 inches expected, locally higher. - Lake effect snow expected Monday night through Tuesday night with some accumulation possible mainly west of US-131. . && Watch and warning map looks interesting.. even DTX pulled the trigger on a warning. GRR will be updating and issue a warning after 6” has fallen and there’s been 200 accidents CWA-wide haha. Link to comment Share on other sites More sharing options...

miamarsden8 Posted November 25, 2018 Share Posted November 25, 2018 NWS really needs to update their blizzard warning. Euro, NAM, RAP, HRRR all have us between 8-12 here in Macomb. Like...I'm sticking with 6-10, but 4-8 by the NWS is gonna be wrong. I could see 8.5-9 inches and with the winds...this would be the best storm I've ever seen down here.

SchaumburgStormer Posted November 25, 2018 Share Posted November 25, 2018 Definitely liking along and just south of a cyclone to DKB to get some of the most brutal blizzard conditions.

Hoosier Posted November 25, 2018 Share Posted November 25, 2018 It won't exactly be a flash freeze around here, but I'm wondering how messy this will get. As mentioned earlier, could see around an inch (if not more) of rain before the changeover, and there's no downtime between precip transition to try to dry things out. Pretty much ripping rain to ripping snow. Could get a nasty ice layer underneath. Link to comment Share on other sites More sharing options...
