12/27 - 12/29 Upper MW/GL's Multi-System Snow Event


Tom

Recommended Posts

The only concern I have here are the warm ground temps which will melt the snow from underneath once all sudden done.  It is looking likely that a solid 2-4" event for our seasons 1st snowfall.  Hopefully this is a start of good things to come.  The fact that this will be a daytime event makes it more enjoyable as well.

DTX tossing the NAM's higher qpf, while still allowing for localized over-performer, so we'll see.

GRR thinks no advisory (warmer temps and weakening as it moves through here), even though snow is falling during the evening commute.  Side roads are still icy/not plowed from previous event.  But they are calling for up to 3" with 1-2" widespread.  The office is schizo.  It's a watch and see event and I bet we see an advisory if the radar trends that way.

We went from a few flurries to moderate snow very quickly.  The latest HRRR shows 1"/hr for a few hours.

The 12z HRRR has completely lost the Wednesday system, only shows a spotty dusting.  The NAM and 3kNAM show a very narrow band of 2-3" through CR and nothing elsewhere.

Radar shows the mixing line already north of Iowa City and approaching Cedar Rapids.  Some models have suggested that line could stall for a bit just south of CR, so hopefully they are correct.

It's possible this could be a system where Hiawatha (north edge of Cedar Rapids) get 3-4" while I get 1-2" on the west side of CR and the airport gets <1".

Looks like a nice snowmaker (if you will) is coming for SMI. I am forecasted for a couple of inches. Lets see if any advisories go out w/ todays 4pm package.

Nice if you stay all snow you should get a few inches I would think.  We're gonna end up with a half inch of snow and a mix of every other p-type down here.  As usual the battle zone is always between I80 and Hwy 30 in Eastern Iowa.

Wow, the latest HRRR actually has another 4" falling in Cedar Rapids.  It does not move the mix line any farther north than it is now.

You guys will do better than me over here as it is struggling to accumulate.   Both air and ground temps are to warm. It’s nice to see the snow falling during the daytime.  Not expecting more than 1” outta this.

Looks like I was 15-20 miles too far south for this one.  We got a burst of heavy snow about 30 minutes ago, but it only lasted a few minutes and switched back to a mix.  We'll be under an inch for the event, but with some decent ice accumulation.  Roads are slick.

The back edge is approaching, but the mix line is surging north ahead of that.  Right now it's nearly on top of me and the snow has pretty much stopped.

My snow total is 3.1".  The liquid total is 0.48".  It started out cold and dry, but ended wet.  While out shoveling the temp warmed above freezing and it began to drizzle.  Just in the last twenty minutes a decent rain shower moved through.

Tomorrow is pretty interesting. Arguably more interested in that system than today's even if snowfall totals are somewhat lesser. Light and high ratio snow on top of today's 3" of slush will really make it look like winter around here.

Meanwhile, the Euro has little more than a dusting across the area Wednesday.

The NWS is not excited about this wave at all... <1" total.
