cyclone77 Posted December 2, 2011 Share Posted December 2, 2011 Been snowing lightly the last hour or so. Started out as a mix of light rain and very small/wet flakes. Ground is warm and snow rate isn't too great, so nothing's sticking. Still nice to see though. Link to comment Share on other sites More sharing options...

wisconsinwx Posted December 2, 2011 Share Posted December 2, 2011 I got some decent light snow as the narrow band was moving through, but it barely managed to put a bit of white on some of the grass. I still have only received a trace of snow this season. I have seen snow fall from the sky this year, but not one flake of accumulation. Tonight is like a microcosm of this year post-GHD blizzard. All I wanted was a dusting, and the rain will end before it has a chance to change to snow (end rant). Link to comment Share on other sites More sharing options...

Geos Posted December 2, 2011 Share Posted December 2, 2011 Something you don't see very often. Lake effect snow being produced off of Lake Winnebago in eastern Wisconsin. 0.2" of snow has accumulated on non-concrete surfaces, but has on my truck! ha!

You're up in the Fox River Valley right now? It's possible we're seeing some lake effect now, b/c it looked like the band was pushing out, but some banding is continuing, almost pushing west based on radar, and it did just turn to snow.

cyclone77 Posted December 2, 2011 Share Posted December 2, 2011 Had some decent sized flakes for awhile, but now it's back to salt sized wet flakes. Just wet outside as if it had rained. Link to comment Share on other sites More sharing options...
hm8 Posted December 2, 2011 Share Posted December 2, 2011 Kinda interesting stuff on the DTX radar right now. On the lowest tilt you can see the returns off to the west struggling to advance into SEMI. However, look on the high tilts and you can see returns making it eventually all the way east of the radar.

No, I was just reading about it from MKX's latest short term forecast discussion. The fetch must be just right tonight for it to occur. "A LAKE-EFFECT PRECIPITATION BAND OFF OF LAKE WINNEBAGO WILL PRODUCE A NARROW BAND OF LIGHT SNOW SHOWERS...MIXED AT TIMES WITH LIGHT RAIN SHOWERS...IN A NARROW CORRIDOR FROM THE CITY OF FOND DU LAC SOUTH INTO EASTERN DODGE COUNTY AROUND THERESA AND MAYVILLE. THE LAKE-EFFECT BAND IS EXPECTED TO DISSIPATE BETWEEN 2 AM AND 3 AM AS WINDS LIGHTEN AND BECOME MORE NORTHWEST. " Link to comment Share on other sites More sharing options...
cyclone77 Posted December 2, 2011 Share Posted December 2, 2011 -SN here with a better band coming in from SQI-RFD Pretty cool on the dual-pol zdr you can see some rain mixing in on the leading edge northwest of LOT. Makes sense since we had a little rain mixed with the wet snow at the beginning. Note the reflectivity jumps to between 5-7DB along the leading edge.

kab2791 Posted December 2, 2011 Share Posted December 2, 2011 Neat stuff. Is that the differential reflectivity?

cyclone77 Posted December 2, 2011 Share Posted December 2, 2011 Neat stuff. Is that the differential reflectivity? Yeah. It's pretty good at finding the melting layer. You just have to be aware of the tilt of the radar beam. If the melting layer shows up 80 miles out from the radar it will be well above the ground, which would imply mostly liquid beneath it.

Thunder Road Posted December 2, 2011 Share Posted December 2, 2011 Most of northern IN gets 0.1-0.2" of light RN/SN showers on Wed. per the 0z Euro. Maybe a few isolated spots of 0.25" in MI. Link to comment Share on other sites More sharing options...

Thundersnow12 Posted December 2, 2011 Share Posted December 2, 2011 The 0z Euro gets close to developing something major with a big western trof at 180hr but stays pos tilt as it moves east and can't get anything going. Link to comment Share on other sites More sharing options...
