Still some nice mood flakes coming down. Finally a system that lived up to the forecast.

 

RC, if you're interested the snow ratio here was 33:1. 0.10" of water for 3.3" of snow.

Very nice fluff you've scored there GEOS - that one exhale from Godzilla would melt (sorry, couldn't resist)

 

seeing this as the highest reported total (so far anyhow) out of GRR's CWA:

Nice rally here, snowing fairly heavily at the moment. Should be short lived though.

Our rallies seem to be getting lamer over the past couple years. :D

Measured about an inch on the table outside. Slight disappointment but maybe we can do better before the inevitable mild up.

Rally was relative. But December 2010 this isn't.

Had an inch final here too. 0.8" from double figures...

Very nice, ultra high ratio FTW, amazing what a little elevation can do up on Mt. Geos :). I'm in ny because of a family emergency but thanks, would have gladly used this if I was at work. Do you ever send us in reports via espotter (if you're a trained spotter) or the public reports link? Also we gladly accept snow reports on our Facebook page. You and a lot of the posters on here really seem to know what you're doing with the snowfall measurements and you're passionate about it, you should seriously consider CoCoRaHS and your reports would always be used as LSRs by the office because reports like that go directly to AWIPS. To be honest, it seems as if we need more trusted spotter reports, sometimes it seems like even the espotter reports that come directly to AWIPS aren't great. I feel like I can always trust the reports here but at times it's tough to check this site when it's very busy.

Some of us are sending them in through espotter when we have a few minutes :)

Nice AFD by LOT regarding the clipper tomorrow night

 

CONDITIONS WILL IMPROVE DURING THE MORNING ON SUNDAY WITH A COLD BY
AND BREEZE BUT DRY DAY EXPECTED. THEN ATTENTION TURNS TO OUR NEXT
TWO CLIPPER SYSTEMS. WATER VAPOR IMAGERY THIS AFTERNOON INDICATES
TWO WAVES: ONE JUST ABOUT TO MOVE ONSHORE ACROSS THE CANADIAN
COAST...AND THE SECOND A FEW HUNDRED MILES SOUTH OF THE ALEUTIANS.
THIS FIRST WAVE IS EXPECTED TO DROP SOUTHEASTWARD ACROSS THE
NORTHERN PLAINS AND UPPER MIDWEST LATER TOMORROW AND SUNDAY NIGHT.
THIS SYSTEM LOOKS TO PRODUCE A DECENT BAND OF SNOW...ALBEIT FAIRLY
NARROW. THE MODELS HAVE BEEN FAIRLY CONSISTENT IN TRACKING THIS
CLIPPER TO THE SOUTHWEST OF THE AREA...WHICH WOULD PLACE THE
FAVORABLE AREA FOR SNOWFALL ACROSS NORTHERN ILLINOIS AND INTO
NORTHWESTERN INDIANA. HOWEVER...THERE HAVE BEEN...AND CONTINUE TO
BE...SOME MINOR TIMING DIFFERENCES AMONGST THE MODEL GUIDANCE.

THIS PARTICULAR CLIPPER COULD PRODUCE A LITTLE MORE SNOW THAN LAST
NIGHTS SYSTEM. IT APPEARS THAT THIS CLIPPER SYSTEM MAY BE ABLE TO
TAP INTO A BIT MORE MOISTURE AS ENERGY MOVING ACROSS THE SOUTHERN
ROCKIES BEGINS TO DRIVE THE SURFACE RIDGE ACROSS THE CENTRAL GULF
COAST SHIFTS EASTWARD...ESSENTIALLY ALLOWING A DECENT NORTHWARD SURGE
OF MOISTURE TO PRECEDE THE SYSTEM. ADDITIONALLY...THIS CLIPPER
APPEARS TO BE A BIT STRONGER THAN ITS PREDECESSOR...AND SHOULD
RESULT IN SOME STRONGER DYNAMICS. THE MOST NOTEWORTHY DYNAMICS
APPEAR TO BE A CONSEQUENCE OF THE MODELS DEVELOPING A POTENTIAL BAND
OF MID LEVEL FRONTOGENESIS ALONG THE NORTHEASTERN PERIPHERY OF THE
SYSTEM. WITH THIS IN MIND...WE APPEAR TO BE LOOKING AT A FAIRLY
NARROW BAND OF MODERATE TO PERHAPS HEAVIER SNOW AMOUNTS SOMEWHERE
ACROSS FAR NORTHERN ILLINOIS AND INTO NORTHWESTERN INDIANA. CURRENT
INDICATIONS ARE THAT 2 TO 5 INCHES WILL BE POSSIBLE WITH THIS SYSTEM
AND THE HEAVIEST SNOW MAY FALL ALONG AND NORTH OF THE I88
CORRIDOR.
..WITH AMOUNTS TAPERING OFF SIGNIFICANTLY TO THE SOUTH
ACROSS CENTRAL PORTIONS OF ILLINOIS. CONFIDENCE IS INCREASING WITH
THE MESOSCALE ASPECTS OF THIS FRONTOGENETIC BAND...BUT DUE TO ITS
FAIRLY NARROW GEOGRAPHICAL EXTENT...ANY SLIGHT DEVIATIONS IN THE
TRACK COULD RESULT IN THE MOVEMENT OF THE HEAVIEST BAND OF SNOW.

For the last 5 hours persistent but very light snow has tacked on another 0.2" for a clipper total of 1.5"....about half of what we saw with Thurs/Fri lake effect event and with similar ratios lol. But I am now very interested in a heavy band of snow that has developed and orientated itself SW to NE and is moving SE across the Detroit area right now. If it holds together could be real fun and also boost our clipper total upward.

That band that is moving in from your n/w will dump around 1" of snowfall...Get ready! It did at my house, around 1"..it was amazing, literally whiteout.

NICE. LOVE whiteouts! In my LES total of 3.1" the other day, I had two near whiteouts. Saw 1.5" came in just over an hour (645-815am) and later 1.0" in an hour (1145pm-1245am) with just 0.6" in between lol.

 

Today thus far it has just been a very gentle snow falling, very winter wonderland, but no really reduced visib....YET.

I'm such a purist that I refuse to measure unless I can measure at 6-hour intervals on a snow board.  And I don't have a snow board.

 

But I took a walk across campus and it looks like a solid 3", maybe 4" in places where the wind has helped out.  I haven't even looked at other area reports yet, so we'll see how they compare.

I love my snowboard....in non-windy snowfalls it is just perfect. You should ask the NWS for a snowboard, they always are willing to help out volunteer observers with the proper equipment in exchange for observations. In the mean time, a flat, non-concrete surface works just as well.
