Chinook Posted December 28, 2015 Share Posted December 28, 2015 The 18z NAM precip-type algorithm has an unbelievable 1.75" of QPF of sleet (3.5" of sleet?) from Kansas City going up towards Cedar Rapids IA (narrowly missing Des Moines?). Something to think about for anyone reading this in Iowa or Missouri. http://coolwx.com/cgi-bin/getptype.cgi?region=nc&model=nam&run=18&fhr=29&field=acctype Link to comment Share on other sites More sharing options...

chasmosnow Posted December 28, 2015 Share Posted December 28, 2015 Forecast has 0.1-0.3" of ice tomorrow here. If the GFS is to be believed, then Madison will be ground zero for the snow. And the model keeps on pushing the snow across the state line into far northern IL... Have been getting feeling all afternoon this could be the big one. GFS. NAEFS ensembles from noon track low over Chicago south of OP noon GFS position and it is that run that produces the map you have put up here.The kind of dynamic up lift that's predicted at 700mb cools air in the snow formation area so hopefully model is right to give us all snow tomorrow afternoon. Is rare we get sleet with a temp of -4 at 850 MB. Tomorrow promises to be an interesting day to say the least! Link to comment Share on other sites More sharing options...

The models that are showing the snow at the onset and further along into the day are interesting to say the least. HRRR is showing 2-3" along the state line I believe. Like this map here showing +SN for you. Between 27>30 hours the column cools for you. It gets really close to sleeting and then the heavy returns move in and dips to 26°. 0 Link to comment Share on other sites More sharing options...

Geos Posted December 28, 2015 Share Posted December 28, 2015 Free Tropical/Cromartie/Plantman! 2nd that. Wouldn't it be cool is the WAA was overdone and some of these colder models actually panned out... Less ice, less power outages. FYI: mid lake buoy temp was 35° at the last obs. So - quite a bit different then the 46° water. Cold air is flowing in pretty good. Link to comment Share on other sites More sharing options...

wisconsinwx Posted December 28, 2015 Share Posted December 28, 2015 0z NAM coming in with another bump east...and stronger. It starts going due north around St Louis.
