bud2380 Posted March 11, 2017 Report Share Posted March 11, 2017 18z NAM was already pretty far north compared to GFS, GGEM & UK and it looks like it will be even further north this run. Quote Link to comment Share on other sites More sharing options...

bud2380 Posted March 11, 2017 Report Share Posted March 11, 2017 Definitely a solid 50-75 mile shift north with the snow placement for most areas. Yuck, rinse, repeat all winter long. Quote Link to comment Share on other sites More sharing options...
bud2380 Posted March 11, 2017 Report Share Posted March 11, 2017 Hopefully this is just the NAM being the NAM, but the Euro looks similar so that is worrisome. GFS, Canadian, & UK are significantly further south, we'll see if they shift north, I'm guessing they will. Quote Link to comment Share on other sites More sharing options...

bud2380 Posted March 11, 2017 Report Share Posted March 11, 2017 Well I'm even approaching 4" on this run and the NAM is quite possibly the furthest north of all the guidance. If the GFS shifts significantly north tonight then I think I'm in trouble. I don't like what the Euro is showing at all though and I'm very concerned it will end up the most accurate.

Tom Posted March 11, 2017 Author Report Share Posted March 11, 2017 Tom, what are your thoughts on this? Northern camp, southern camp?Would like to see the GFS/RPM run tonight. RPM does well at this range. NAM is earily similar to the Euro in track thru IA so won't discount it. Let's see the runs tonight. Quote Link to comment Share on other sites More sharing options...
Tom Posted March 11, 2017 Author Report Share Posted March 11, 2017 Just saw the RPM and it looked the same as it did earlier. One thing it's picking up on are distinct lake bands coming off the lake later Monday evening when the system snow departs. The run stopped at about 7pm Monday but the lake snow will prob continue into Tuesday. Quote Link to comment Share on other sites More sharing options...

Money Posted March 11, 2017 Report Share Posted March 11, 2017 There was one LE event back in March 3rd, 2009 that hit Milwaukee international airport with 14 inches of snow while 15-20 miles inland they got nothing y 6 p.m. Monday, Milwaukee's Mitchell International Airport had recorded 14.4 inches of the light snow, beating the previous record snowfall on the same date of 9.4 inches in 2002. Eight inches had fallen by daybreak, and the snow hampered commuters in the lakeshore areas of southeastern Wisconsin. Snow plows worked through the day to clear roadways as the snow continued off and on. Quote Link to comment Share on other sites More sharing options...
