Hoosier Posted January 11 Author Report Share Posted January 11 Not the best continuity spanning across the warning area with the 2 counties in northwest Indiana left out. I'm sure the LOT afternoon afd will be informative though and may shed light on the reasoning. Quote Link to comment Share on other sites More sharing options...
hawkstwelve Posted January 11 Report Share Posted January 11 RDPS trend over the past four runs. It's remaining pretty consistent in it's solution overall for the past three runs. None of these crazy run-to-run swings like the NAM and HRRRRRR. Gives it at least a little more weight, IMO. 1 Quote Link to comment Share on other sites More sharing options...

East Dubzz Posted January 11 Report Share Posted January 11 Actually, I guess Dubuque didn't get the Blizzard Warning. Interesting. Not supposed to be an windy over here? Now that I look.. I guess not. Though not too far off. Gusts of upper 30s tomorrow night instead of mid 40s for the other areas. Quote Link to comment Share on other sites More sharing options...

hawkstwelve Posted January 11 Report Share Posted January 11 Quite a few models show Minnehaha County, where Sioux Falls is located, being the dividing line between the heavier totals and the lesser totals. Depending on how things ultimately shake out it could be a situation where the NW corner of the county gets 1-2 inches and the SE corner of the county gets 5-6 inches. This is exactly what the latest RAP model shows - 1 inch in the NW of the county and 6 inches in the S/SE. Another good example of this is Lincoln County just to my south, which starts literally across the road from my house, is under a Winter Storm Warning for 5-9 inches. I have a Winter Weather Advisory here for 2-6 inches. Luckily I am as far south in the county as you could possibly get. Ultimately it's pretty clear that there is going to be a sharp gradient for snowfall totals here. I just hope I'm on the right side of it. 1 Quote Link to comment Share on other sites More sharing options...

The Snowman Posted January 11 Report Share Posted January 11 50 minutes ago, jcwxguy said: This makes little sense to me - essentially taking 10:1 maps and calling it a day. NWS Omaha expecting much higher ratios though, with their fresh AFD: Quote .DISCUSSION... Issued at 320 PM CST Thu Jan 11 2024 Overall, the forecast remains on track for another strong winter storm to impact the region tonight through Friday. This will be the second winter storm with heavy snow this week. Changes with this forecast from the previous package include a slight shift upwards in our snowfall ranges by about an inch. We are seeing snow develop already in northeast NE this afternoon, north of a line from Albion to Wayne, with visibility down to 1 mile at both Oneill and Yankton. We should see snow start to fill in across eastern NE through 6 pm, and southwest Iowa by 6-8 pm. The snow may come in waves when it begins and then finally fills in becoming moderate to heavy by 9pm-12am, which then continues overnight and into Friday morning. Northerly winds overnight range 15 to 30 mph. With the colder temperatures, we`re expecting higher snowfall ratios closer to 15 to 18 to 1, so the snow won`t be as heavy and wet as it was with this past system last Monday, and will blow around a lot easier too. The snow does linger into Friday morning, with the accumulating snow really tapering off Friday afternoon. With snow and blowing snow comes colder temperatures, and wind chill values are as cold as 15 to 20 below zero across eastern NE as well tonight and Friday morning, thus the existing winter storm warning and wind chill advisory will continue tonight and Friday. We feel that while near blizzard conditions are possible overnight and Friday especially in open areas, it might be hard to get the strict definition of 35 mph wind gusts and 1/4 mile visibility, but travel will still be extremely difficult especially in open areas on east/west roads with the blowing snow. 1 Quote Link to comment Share on other sites More sharing options...

Though I think refs getting to the game could potentially be a problem. I would hope for fan safety they cancel. Iowa was once a couple hours before tip all ready to play Indiana in Bloomington when a game got canceled because a ceiling tile fell. It was late in the season and couldn't have come at a worse time too. Iowa ended up cramming the makeup game in and had to play 3 straight road games in one week and lost them all. So they shouldn't feel bad about canceling on Nebraska tomorrow. Quote Link to comment Share on other sites More sharing options...

Wonder if they need to update that? I noticed that as well. They have been kind of weird lately not matching up their point forecasts/graphics/warnings. The official warning for me says 7-14, though the graphic is pretty much 8-12+ area wide around me. Minor stuff, but a little coordination there would be nice haha Quote Link to comment Share on other sites More sharing options...
The Snowman Posted January 11 Report Share Posted January 11 Also strange: if OAX (and most all models, for that matter) are correct in ratios landing somewhere between 15:1 and 18:1, why is NBM going with 8.8" of snow just north of Omaha from 0.71" QPF (ratio of just above 12:1)? 1 Quote Link to comment Share on other sites More sharing options...

Grizzcoat Posted January 11 Report Share Posted January 11 DMX AFD- It is worth noting that the forecast snowfall totals from the upcoming storm combined with those from the storm earlier this week will raise five-day snowfall amounts from Monday through Friday of this week to near all-time records, making this one of the snowiest weeks in history for portions of the area. 5 Quote The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.
