Natester Posted March 13, 2017 Share Posted March 13, 2017 Puking snow right now. Looks to stay that way for awhile. I'm pretty sure hawkeye is dancing right now. This totally blows away those wimpy snow events we had between the last time it actually snowed (on December 17, 2016) and tonight. Link to comment Share on other sites More sharing options...
tuanis Posted March 13, 2017 Share Posted March 13, 2017 Light snow has commenced. Hoping to break half a foot. Forgot what it feels like to look forward to a snowfall. Link to comment Share on other sites More sharing options...
Justin Posted March 13, 2017 Share Posted March 13, 2017 little bit of snow grains and misty snow starting to fall in Muscatine, Iowa. Atmosphere taking a hair longer to saturate as we had a pretty stout layer of dry air to moisten up. still think that dry air eats into some of the qpf here locally in east central iowa. gonna say 4-5" for the QC metro will be about it I think, unless we get some surprise accumulations tomorrow after about 9am. I'm Jerry Taft'ing the quad cities. Link to comment Share on other sites More sharing options...
Snowstorms Posted March 13, 2017 Share Posted March 13, 2017 0z Nam is definitely a little more wetter for the GTA than the 18z Nam. Has amounts of 2-4" with ratios whereas the 18z had only 1". Lets see what 0z RGEM says. Link to comment Share on other sites More sharing options...

blizzardof96 Posted March 13, 2017 Share Posted March 13, 2017 The HRRR/4kNAM depiction of the initial wave looks reasonable IMO with it being a relatively dry wave. Where the golden horseshoe has the best shot at a decent band will be once the baroclinic leaf expands during the day tuesday. That is when the LE band could set up.

blizzardof96 Posted March 13, 2017 Share Posted March 13, 2017 After reviewing some sounding data, it's actually ~20z tomorrow when inversion heights are the most favourable for LE across the YHM-Niagara corridor with a gradual decline after that timeframe. But in terms of synoptic banding, tuesday looks better IMO. Link to comment Share on other sites More sharing options...
Justin Posted March 13, 2017 Share Posted March 13, 2017 Now starting to snow steadily here, but very very fine misty snowflakes, not the big fat ones that easily accumulate. Will need to watch this trend over the next few hours to see if flake size increases or not. Link to comment Share on other sites More sharing options...
Hoosier Posted March 13, 2017 Author Share Posted March 13, 2017 7 hours ago, Chicago Storm said: Interesting system that will be breaking the futility for Chicago. Unfortunately it won't have full potential, and the system will be weakening as it slides into the area, with early transfer occurring to the developing East Coast system. Looks like a solid 2-6" for much of the LOT CWA with the synoptic snow. Then the LE is still up in the air. Should be some enhancement during the synoptic snows, before becoming pure LES tomorrow evening into Tuesday. Probably will see a multiple band setup try to converge into a single plume. How soon does that occur is one question. Then the next question is how transient will it be. So it's definitely up in the air a bit still, but could see several inches of LE in WI/IL with it. Assuming an organized single band forms, it should be able to produce rates of 1-2" per hour. I'd rather be on the Illinois side for this one but I'm thinking it should rip here pretty good for a while. Link to comment Share on other sites More sharing options...
Snowstorms Posted March 13, 2017 Share Posted March 13, 2017 0Z RGEM came in slightly wetter for the GTA. Has 3.0" with 10:1 snow ratios and with 15:1 snow ratios it equates to 5.0". A subtle shift of 50 miles further West could mean closer to 6-7". Link to comment Share on other sites More sharing options...
cyclone77 Posted March 13, 2017 Share Posted March 13, 2017 Light snow started here a short while ago. Flake size still very small, but top-down saturation is still ongoing. Dew is still in the upper teens here. Link to comment Share on other sites More sharing options...

Justin Posted March 13, 2017 Share Posted March 13, 2017 ground finally starting to get a little white on it, but still just a heavy pixie dust falling. tiny, tiny flakes. visibility here around 2 miles roughly so not an intense rate at all. still dont see the higher amounts verifying locally at least.

UMB WX Posted March 13, 2017 Share Posted March 13, 2017 Been snowing real nice for last 3 hrs.. Eyeballing - I'm Guessing will be closing in on 3" within the next hr. Link to comment Share on other sites More sharing options...
cyclone77 Posted March 13, 2017 Share Posted March 13, 2017 Top down saturation looks to be finally complete here, as the dew has risen to 26, and the snow is falling much more efficiently. Flake size is still quite small, but it's pouring out there quite nicely. Heavier snows have regenerated out in central IA and will work it's way through the DVN cwa between now and sunrise. Some nice totals up near the Waterloo area so far. Some locations have already picked up 6-7" of snow. Could be some double digit amounts up that way. QC may end up with more than 6" if we can get some of those high-ratio bands to work in as the surface-850mb lows approach/pass by later in the night.

hawkeye_wx Posted March 13, 2017 Share Posted March 13, 2017 After piling up the first few inches in a hurry, our snow rates have dropped way down. From 8pm-10:30pm I received 2.8 inches, but from 10:30pm-12am only another 0.6". A guy on the other side of town has nearly 5" and a town 17 miles north of Cedar Rapids amazingly has 8 inches. There was obviously a localized pocket of very heavy snow just north/northeast of me. DVN isn't too enthusiastic about the rest of the area outside the localized high amounts. The low track has really shifting south today. Models had locked into a track across southeast Iowa, but instead it's going to dive down through Missouri, even sw of St. Louis. That south track will take some of the better forcing and moisture with it. Link to comment Share on other sites More sharing options...

Those are some pretty crazy variations. Very interesting. Since you're already at 3.4" you should make a pretty good run at legit warning criteria amounts, as you look to get a good 2-3" more between now and mid morning.

cyclone77 Posted March 13, 2017 Share Posted March 13, 2017 Snow globing out there now with very nice dendrites. Already near an inch, with most of that falling in the last 45mins. Link to comment Share on other sites More sharing options...
Snowstorms Posted March 13, 2017 Share Posted March 13, 2017 Stayed awake, thanks to a massive project, just in time for the 0z Euro. 0z Euro holds ground, albeit a tick drier than 12z Euro, still has 5-6" in the GTA without ratios and would equate to 7-9" using 15:1 snow ratios given the cold temperatures.

Justin Posted March 13, 2017 Share Posted March 13, 2017 good dendrites finally this last hour or so and it continues. looks like decent snows for the next 3-4 hours here. thinking 3-5" for much of the area is going to cover it well. air temps still a bit ehhh as we are holding at 30.4 degrees. initial bit of snow compacted/melted on contact. radar looks good from our area and West.

cyclone77 Posted March 13, 2017 Share Posted March 13, 2017 Over 2" now here, with nice dendrites still raining down. HRRR/RAP show an additional 0.3-0.4" of precip for the QCA, so should easily see another 4-5". Looks like a warning criteria event after all for the QC.

Chicago Storm Posted March 13, 2017 Share Posted March 13, 2017 Have about 0.5" thus far.After some lighter precip recently, better returns are moving in for the first time.HRRR continues to have 3-4" by the time synoptic snows end during the day.

Chicago Storm Posted March 13, 2017 Share Posted March 13, 2017 0.4" at ORD as of 1AM. The sub-1" snowfall streak was able to add on one more day before ending. Link to comment Share on other sites More sharing options...
snowstormcanuck Posted March 13, 2017 Share Posted March 13, 2017 Really long fused by I think about 6" when all's said and done looks reasonable for Toronto. Subtle shifts in the ul/sfc low will have a major impact though as I think the northern QPF boundary will be tighter than what the RGEM/UKIE are trying to sell. There's a lot of dry air associated with that banana high. Nail biter for Boston on the EURO...lol. Link to comment Share on other sites More sharing options...
michsnowfreak Posted March 13, 2017 Share Posted March 13, 2017 DTX has a WWA for 2-4" with the 4" amounts expected Detroit south and east. Latest models do tend to have highest qpf ARB-DTW south. Thinking this ends up a dry 4-inch snowfall. Snow began around 5am. Hoping for a nice wintry day! Link to comment Share on other sites More sharing options...
Baum Posted March 13, 2017 Share Posted March 13, 2017 wet pavement. Still no need to use a snowblower. I suspect once the sun gets up it'll be very difficult to accumulate on the pavement. Maybe tonight's lake effect action can get it done. Link to comment Share on other sites More sharing options...
