Jan 4 Cleveland NWS this morning: q. 6 to 8 inch storm totals for northwest ohio seems reasonable at this point. q.. A bit more snow is expected in southeast Michigan. Toledo's forecast low for Tuesday morning is -15. hr. Last two runs of the NAM model have taken a slight jog to the west with the heaviest snow. This could likely result in a very tight gradient across the Toledo Metro area specifically if it verifies (GFS is still east). Example of what I'm talking about... Delta, Swanton, and much of western Lucas County 8-10". Monroe, Toledo, Maumee, Waterville, down through Henry County 6-8". Eastern Lucas County through BG 3-5" Port Clinton to Findlay 1-2" It's not unusual to have a tight gradient like this over a small area, so people just need to have some understanding of the possibility. When people don't get this then end up calling out forecasters for screwing up the forecast because their street corner didn't get X amount of snow. If you get really close in to the NAM solution on Lucas County itself, it does go from 8-10" NW and WC part of the county to 4-5" in the eastern tip. Keep in mind there is always a margin of area on placement in forecast models, and I definitely don't think it's going to end up exactly like that...but could sway 20-40 miles either way. ! posted by JustaSooner on Jan 04, 2014 at 10:03:43 am #weather
