smoof Posted March 1, 2015 Share Posted March 1, 2015 I'm confused...is that supposed to match this one? That shows more snow for 48 hours than the Earl Barker map for 120. http://wxcaster.com/gis-gfs-snow-overlays.php3?STATIONID=GRR Probably just a difference in their snow ratio algorithms. Snow ratios might be hard to figure out with this one assuming it doesn't end up going more north and being sleet / freezing rain, I've had WAA front end thumps like this overperform and have higher ratios than I expected quite a few times before but who knows what this one will do.

Chicago WX Posted March 1, 2015 Share Posted March 1, 2015 Not real big changes on the 12z Euro. Maybe a smidgen north with everything, compared to its 0z run. Link to comment Share on other sites More sharing options...
Chicago WX Posted March 1, 2015 Share Posted March 1, 2015 On the other hand, 2nd piece is coming a bit north on the 12z Euro. Northern AR, southern parts of MO-IL-IN-OH, and northern KY all do fairly well. Link to comment Share on other sites More sharing options...

WestCoaster Posted March 1, 2015 Share Posted March 1, 2015 Current 12z YYZ model summary UKIE: All frozen--SN/PL mix(0.6-0.8" QPF) GEM: 6-7hrs of SN/+SN, 3 hrs of PL, 3-4hrs of -RN/FZDZ GFS: 2-4" of SN followed by -RN/RN ECM: Pending NAM: Brief SN---> +PL---> -ZR----> -RN. (0.3" QPF). It's a mess. None of those outputs excite me in any shape or form. Give me a legit storm or give me warmth. Link to comment Share on other sites More sharing options...
TugHillMatt Posted March 1, 2015 Share Posted March 1, 2015 None of those outputs excite me in any shape or form. Give me a legit storm or give me warmth. 6 to 8 inches of snow/sleet don't excite you? I'm guessing it's because of the mix? Link to comment Share on other sites More sharing options...
BadgerStateWX Posted March 1, 2015 Share Posted March 1, 2015 not good when thundersnow is not posting much This one always had a feel that it would not trend favorable back south like we could bank on all winter. Link to comment Share on other sites More sharing options...
blizzardof96 Posted March 1, 2015 Share Posted March 1, 2015 12z EC has 3-5" GTA wide with a PL mix towards the end. Link to comment Share on other sites More sharing options...
WestCoaster Posted March 1, 2015 Share Posted March 1, 2015 6 to 8 inches of snow/sleet don't excite you? I'm guessing it's because of the mix? UKMET's output would doubtfully drop 6-8" on the ground. Ratios would really have to pan out, as well as precip type. We've had a handful of systems over the last two seasons dump 6-10". We haven't had a 12"+ system since February 2013 and that was after a 5 or 6-year snow storm drought. It has been Toronto airport's coldest month in recorded history. I'm quite tired of winter. Unless there's going to be a really awesome storm (high winds, huge accumulations, or impressive snow rates), then I'm ready for warm anomalies. Unfortunately, this system does not look to dump huge snow or have high winds for YYZ, nor will there be sustained +SN by the looks of it. Hence, uninterested.

I think this winter is breaking a lot of people haha. Im still going to be excited for 2-4" and 0.2-0.3" of freezing rain. Also another reason I will never give up on snow in March is because chances are its the last winter storm you see. Unless you live in the higher elevations once March 15-20th rolls around Im pretty much given a slop of 1" while higher elevations get the 4" Link to comment Share on other sites More sharing options...
Brewers Posted March 1, 2015 Share Posted March 1, 2015 This storm defines our winter. Uninspiring. Model avg is around 0.25" and looking at soundings I don't see anything that jumps out at me. SREF mean has been consistent with 0.35-0.40" but for now I'm going with 2-4" of snow. Link to comment Share on other sites More sharing options...
TugHillMatt Posted March 1, 2015 Share Posted March 1, 2015 Based on what can I can see on the 18Z run of the NAM, it looks like it may be heading south and closer to what the GFS has been showing. Link to comment Share on other sites More sharing options...
Chitown Storm Posted March 1, 2015 Share Posted March 1, 2015 Models are still all over the place with amounts. NAM going way NW with the best snow in MN. I could care less what we get at this point. If there's enough snow to cover the driveway I'm firing up the thrower. Gotta burn up the old fuel. Link to comment Share on other sites More sharing options...

mimillman Posted March 2, 2015 Share Posted March 2, 2015 For what it's worth, my analysis shows that surface temperatures are currently higher than what the 12z GFS predicted across much of the subforum. This may limit freezing rain accumulations. Link to comment Share on other sites More sharing options...

Assuming big snow potential is off the table ATP, I think most here would take a cold rain over ice or *(expletive)*. So hopefully you're correct.

Chitown Storm Posted March 2, 2015 Share Posted March 2, 2015 21z SREF plumes still with a mean of 5", almost the same as the 15z. But the 21z lost 2 big dogs over 10". So a handful of models increased snow totals. The potential torch run on some of the models has me thinking spring and warm temps. Let's get this snow system out of the way. Onward and upward.

smoof Posted March 2, 2015 Share Posted March 2, 2015 0Z NAM looks like it is going to stay near it's northern "outlier" solution so far through 36hrs, southeast ridge is a tiny hair stronger at 36h so far too. Link to comment Share on other sites More sharing options...
smoof Posted March 2, 2015 Share Posted March 2, 2015 Hmm yep, 0z NAM tracking the low a bit NW of Green Bay this run, it's most north run so far, still riding the 850mb 0c snow line here in Central MI yet again. Link to comment Share on other sites More sharing options...

Argh. I have been waiting for it to sink south like it has with all these other systems...but of course not. Pretty much all the models are showing my area getting 4 to 6 inches except the NAM. I've noticed that when the NAM disagrees with them, it almost always seems to win. GRR NWS is hugging the NAM too. Well, hopefully the MN folk can get some good snows.....

I dissed the NAM early in the season saying it wasn't so good picking up on trends after it's last upgrade, but well that was my mistake it has been very hot on picking up on north trends and decent on south trends too, I pretty much have to take it seriously after watching it over the many many storms there have been this season to track.

Chitown Storm Posted March 2, 2015 Share Posted March 2, 2015 Yeah the 0z NAM tracking the low over extreme SE MN up towards Green Bay. No issues with p-types here, but the track pushes the better snow to the NW of here. Link to comment Share on other sites More sharing options...

Storms everywhere but here. lol I saw that Mt. Pleasant has only had 17 inches of snow this winter? That's crazy. The NAM is a mess for all of Lower Michigan now.

smoof Posted March 2, 2015 Share Posted March 2, 2015 How much snow do you have on the ground over there? I haven't really measured my snowpack but just by eyballing it, about 9-10" on the ground in my partially shaded wind protected yard I would guess.

TugHillMatt Posted March 2, 2015 Share Posted March 2, 2015 Some of the other NAM runs look decent for us to get 3 to 5 inches still. http://www.tropicaltidbits.com/analysis/models/?model=namconus®ion=us&pkg=asnow&runtime=2015030200&fh=69&xpos=0&ypos=582 http://www.tropicaltidbits.com/analysis/models/nam4km/2015030200/nam4km_asnow_us_21.png Link to comment Share on other sites More sharing options...
