DominicR Posted February 3, 2014 Report Share Posted February 3, 2014 A developing winter storm out of southwest today will bring heavy snows to the Plains tonight and eventually into the lower Lakes and Ohio Valley tommorow and early Wednesday. Currently looks like heaviest will miss Quads, Chicago and Detroit but these areas could get 3-6 inches while areas in N MO/S IA/C IL/IN/OH could get 6-12 inches with locally more. Latest 06z NAM has gone a tad north and wetter up the I-80 north corridor while it has shrunk heavy snow band in IN. Plenty of time still for adjustment(s). 50-60 mile north would put the big cities right back in the heaviest axis of snow! 06z NAM Snowfall: Quote Link to comment Share on other sites More sharing options...

DominicR Posted February 3, 2014 Author Report Share Posted February 3, 2014 WSW's out for C IL/IN now. GFS came a little drier over here. I am gonna with 3-5 inches up to the border and possibly MKE last entire row of counties for now. KSC to Peoria look good for 6-10+ Quote Link to comment Share on other sites More sharing options...

Tony Posted February 3, 2014 Report Share Posted February 3, 2014 Unless things change in the next 24hrs this will not be our storm maybe just a refresher at best. Seems the southern route is the way to go with the next couple systems. Quote Link to comment Share on other sites More sharing options...
Tom Posted February 3, 2014 Report Share Posted February 3, 2014 I agree Tony, looks like the southern Plains/Midwest is in the bullseye for the next 2 systems. East coast looks like there are going to get a bomb this weekend. Quote Link to comment Share on other sites More sharing options...
Tony Posted February 3, 2014 Report Share Posted February 3, 2014 The word is that the 12z GFS is having feedback issues and is pretty much a worthless run as nothing seems to be matching up. Quote Link to comment Share on other sites More sharing options...

East Dubzz Posted February 3, 2014 Report Share Posted February 3, 2014 Where is this blocking coming from? Both AO/NAO look to be positive or neutral, and the PNA is definitely negative. Is it a -WPO/EPO? It has to be, otherwise I'm just confused. Quote Link to comment Share on other sites More sharing options...
Tom Posted February 3, 2014 Report Share Posted February 3, 2014 Ya, I think it is the tanking WPO which produces and eastern trough and that is outweighing the -PNA. We both discussed about this possibly being an issue for us around here that may suppress the system. Quote Link to comment Share on other sites More sharing options...
Sciascia Posted February 3, 2014 Report Share Posted February 3, 2014 Model madness is keeping things interesting. With GFS feedback issues & a met on AmWx saying that even the RGEM may be too SE with the low, it's tied me into another full day of model runs.

indianajohn Posted February 3, 2014 Report Share Posted February 3, 2014 is there any possibility it shifts 50 miles or so north and hitting Northwest Indiana, or will it pretty much stay south in central indiana? Quote Link to comment Share on other sites More sharing options...

Tony Posted February 3, 2014 Report Share Posted February 3, 2014 is there any possibility it shifts 50 miles or so north and hitting Northwest Indiana, or will it pretty much stay south in central indiana?There is always that possibility especially with quite a few METS thinking the slp is too far SE. Of course the models could be right but that really hasn't been the case this winter. Quote Link to comment Share on other sites More sharing options...
Tony Posted February 3, 2014 Report Share Posted February 3, 2014 Can't give up hope so will wait it out till 12z models tomorrow. Maybe by then the models will have a clue as to what is going on. Quote Link to comment Share on other sites More sharing options...
Geos Posted February 3, 2014 Report Share Posted February 3, 2014 Skilling holding steady at 3-7". Kind of saw his map in the background.

Hawkeye Posted February 3, 2014 Report Share Posted February 3, 2014 The GGEM and UK have now gone under 0.20" here. For us, this system is slowly fading into another nickeler.

Tony Posted February 3, 2014 Report Share Posted February 3, 2014 I had this in the wrong thread so here it is again: There are some METS on Americanwx chiming in on this storm which is always a plus and a learning experience as well. They are pretty much saying in a nutshell that they believe that the slp is to far east. Here are some exerps from their posts: "Agreed. At least it's very apparent that the GFS is erroneously jumping the surface low center to the warm sector convection instead of tucked in closer to the midlevel trough hundreds of miles away over the OV as it should. This will make it easier to discount""Even the RGEM to an extent tries to do what the GFS is doing, the difference being it starts the low much further north and in a more correct location with regards to the upper level trough" http://collaboration...pe_gem_reg.html "You can see it as you tick through the hours, once the convection weakens the RGEM refocuses back at the main low" "Yup, that's clear to see there, so it's conceivable that even the RGEM, while much better than the GFS, might be too far southeast at least initially with the slp placement" "When a storm system taps pacific moisture it almost always overperforms. Check out the huge moist plume from the south/central Pacific on water vapor. That would suggest that the models with the higher QPF totals might be more representative than the others" Quote Link to comment Share on other sites More sharing options...
Geos Posted February 3, 2014 Report Share Posted February 3, 2014 Going to have to count on the LES up this way. Otherwise one or two inches might be it.
