hlcater Posted October 29, 2019 Share Posted October 29, 2019 2 hours ago, IWXwx said: Nice catch. Probably the real difference is ground temps. Farther east for sure, but I'm wondering if even the effects of ground temps in IA/NW IL may end up being somewhat minimized since the past 4-5 days prior to Wednesday would have been in the 30s/40s. In other news, I also got 2.5" from this system, like many others in my area. Might be able to sneak a few more Wed/Thur, but looking like that system slides to our SE.

Hoosier Posted October 29, 2019 Author Share Posted October 29, 2019 Tonight is a good example of how it can snow south of the 540 dm thickness line and the importance of checking soundings. It happens when you have relatively warmish temps aloft with a fairly deep layer hovering around/slightly below freezing. In this case it may be snowing in places with 546 dm thicknesses and every so often it can snow with thicknesses even a tad higher than that. 3 Link to comment Share on other sites More sharing options...
fluoronium Posted October 29, 2019 Share Posted October 29, 2019 HRRR hinting at some thundersnow It would be crazy to get an accumulating snow this early here, especially after the April 15 storm barely over 6 months ago. Normally I'd complain about the cold at this time of the year but we have actually had good fall temps these past couple months (unlike 2018, the year without transition seasons) 1 Link to comment Share on other sites More sharing options...
Hoosier Posted October 29, 2019 Author Share Posted October 29, 2019 Sort of a minor detail but there should be a little lake enhanced precip on the western side of the lake before the flow backs around on Thursday. Link to comment Share on other sites More sharing options...
Hoosier Posted October 29, 2019 Author Share Posted October 29, 2019 12z Euro has 2-3" all the way to the Chicago lakefront. Def zone is definitely the better bet to get some accumulation there as winds flip offshore. Should be some moderate bursts in that precip shield.

A-L-E-K Posted October 29, 2019 Share Posted October 29, 2019 i've completely tossed any chance of WAA snows here, heavy returns gonna be south there anyways, it's defo or bust. Link to comment Share on other sites More sharing options...
Thundersnow12 Posted October 29, 2019 Share Posted October 29, 2019 Euro is south with the initial front band but makes up for it Thursday with a nicer look at H5 that leads to a fairly long period of accumulating snow on Thursday. Link to comment Share on other sites More sharing options...
A-L-E-K Posted October 29, 2019 Share Posted October 29, 2019 that seems to be the way to go, probably better for mby anyways flakes falling during trick or treating looking like a good bet so that's a win 1 Link to comment Share on other sites More sharing options...

Indystorm Posted October 29, 2019 Share Posted October 29, 2019 My goodness, I just came back from a ten day trip to New Orleans and the MS Gulf coast to find a serious winter thread for the Midwest after basking in what will probably be my last 70 and 80 degree temps of the year. On to winter! 1 Link to comment Share on other sites More sharing options...

Hoosier Posted October 29, 2019 Author Share Posted October 29, 2019 18z RAP and HRRR differ on amounts, but the common theme is to bring snow farther south into parts of far northwest Indiana especially away from the lake.

GRR has been down-playing any chance with this synoptic threat to this point, but with models continuing to up the ante they may finally get on board.

Really not sure what's going to happen here at my place on Wed morning. You could argue anything from all rain to a sloppy couple inches or so. I suspect neither of those outcomes will be right and that the answer lies somewhere in between. I just still have a hard time believing that the onshore flow at that progged strength is going to be entirely successful at preventing snow from occurring once you get this distance away from the lake. Now this is assuming heavy precip rates to assist with cooling. If precip stays on the lighter side for some reason, then it would have a very hard time snowing. 1 Link to comment Share on other sites More sharing options...

Hoosier Posted October 29, 2019 Author Share Posted October 29, 2019 18z NAM is deeper with the surface low. Keep an eye on that to see if it's a trend... quicker deepening = more robust low level wind response = more of a problem where trees are caked in snow. 1 Link to comment Share on other sites More sharing options...

Really hoping for a snow globe effect while the kids trick or treat and no appreciable accumulation for that reason alone. I don't want to be losing tree limbs or being out there knocking snow off my more sensitive landscaping. These early/late season sloppy cake jobs have been commonplace the last few years up here and are a real PITA. Link to comment Share on other sites More sharing options...

Yeah that's going to cause widespread power outages. Likely won't be a problem here since temps will be going below freezing shortly after the snow starts, although some caking of the trees is inevitable.
