hlcater Posted February 11, 2019 Share Posted February 11, 2019 I have a feeling this is the one to get us to 6". It's been puking snow here and never really stopped. Flakes are pretty small right now though. Probably 1.75" in IC already. That band of orange that passed over me earlier was really something.

So far sleet has dominated and the main surge of WAA is still on the way. Good chance we get 1"+ sleet out of this. I wonder why. Is the storm running any bit northwest of the latest model runs? It’s been a mix of snow and a bit of graupel since it started ripping at 1:45pm here. Seems like it’s been mostly straight snow here for awhile and looks like we have a good inch so far. Radar still looks like the heaviest snows are a county or so east of i35 but decent snows are extending west over our area and even a few counties west of that so the cutoff doesn’t appear to be tight with this. I’m going with 4.5 inches here just like the forecasts predict Link to comment Share on other sites More sharing options...
Baum Posted February 11, 2019 Share Posted February 11, 2019 starting as sleet. Not a good sign, as I'm guessing we go to freezing rain next.... Link to comment Share on other sites More sharing options...

Hoosier Posted February 11, 2019 Share Posted February 11, 2019 Suppose I'll make a call. I will go with about a quarter inch of ice imby, then ending with a bit of snow tomorrow. Wouldn't be surprised to go a bit over on the ice as accretion efficiency looks excellent for the next few hours before it probably gets a bit worse.

hlcater Posted February 11, 2019 Share Posted February 11, 2019 Back to 1"/hr rates easy. Flakes are only average sized but there's so many of them it looks like heavy rain almost. Can't see the U of I hospital, about a 1/2 mile away. Vis is definitely under 1/4 mile atm. Link to comment Share on other sites More sharing options...

The latest run has finally caught on though, and now keeps us all sleet and freezing rain until after midnight. Using a 3:1 ratio for sleet, it's looking like 1-1.5" of sleet, but if some of that is freezing rain that will cut into that. There is a smidge of freezing rain mixing in now, so wouldn't be surprised to see freezing rain become more dominant than sleet for awhile at some point.

Sounds like our weekly weather lately lol. At least it's going to be a normal WAA to snow progression for ya not bass ackwards like its been around here.

At least the sleet provides traction for drivers. But I am surprised after all the juicy eastern IA snowfall maps I saw today i called my job today and I was lucky the general manager gave me the night off because I have rear wheel drive and would get stranded with the amount of snow we are getting on the roads now Link to comment Share on other sites More sharing options...
hlcater Posted February 12, 2019 Share Posted February 12, 2019 Yea the mixed precip line is coming northward pretty fast. Looking like a mix is probable in Iowa City for a period. Areas just to my north and west should be okay(CR). Link to comment Share on other sites More sharing options...
cyclone77 Posted February 12, 2019 Share Posted February 12, 2019 Sleet is really piling up out there. Probably 1/3" to 1/2" already on top of the 0.3" of snow that fell earlier. CC doing a great job at showing the snow/mix line. The loops shows the snow/mix line slowly advancing northward as well. Link to comment Share on other sites More sharing options...

Chicago Storm Posted February 12, 2019 Share Posted February 12, 2019 Pretty clear the warmer NAM is the way to go, and the GFS will be set up for an lol worthy fail.

hlcater Posted February 12, 2019 Share Posted February 12, 2019 Mix in Iowa City now. WAA was undermodeled essentially across the board with the worst offenders being the RGEM, GFS and RAP. This will cut into my total, perhaps significantly. Link to comment Share on other sites More sharing options...

Judging by how fast the rain/sleet line is moving, we're going to see some sleet. Hopefully no freezing rain. Link to comment Share on other sites More sharing options...
