harrisale Posted February 27, 2013 Share Posted February 27, 2013 Snow and Sleet really battling it out right now. Just when it looks like one is winning, the other makes a comeback. I am surprised how far inland some of the mixing has penetrated though. Guelph looked like it was going to be completely immune from all this. Goes to show you how delicate these setups are. Yep, certainly didnt expect mixing up here. Maybe that warm air layer on the NAM had something to it after all! Latest obs still showing us below freezing (-0.7) at the surface, yet almost all rain coming down. Link to comment Share on other sites More sharing options...

Latest obs still showing us below freezing (-0.7) at the surface, yet almost all rain coming down. Maybe. I threw it under the bus when it first showed up and it lost it on its 12 and 18z runs but maybe there was something to it. Per SPC mesoanalysis, 925 and 850 mb temps are below freezing, so it maybe a layer of warmth even further up in the atmosphere. Link to comment Share on other sites More sharing options...
snowstormcanuck Posted February 27, 2013 Share Posted February 27, 2013 My temperature is -0.9 celsius. Hopefully the snow can hold up here. It's about warmth aloft, not at the surface. Link to comment Share on other sites More sharing options...

Geos Posted February 27, 2013 Share Posted February 27, 2013 Wow. Even after today's 4.2" we're under 10" lol. Wow! You've really done well didn't realize you picked up that much. I use the Co-op West Racine data as my reference and they have 18.9". Just add 10.4" to that table below and that tells the story! But yeah quite a gradient to my south and west.

YHM Supercell Posted February 27, 2013 Share Posted February 27, 2013 Dave please tell me that the dual pro shows that the rain here in Mississauga should switch to snow soon? Doesn't look like you'll be going to all snow for at least 30 min maybe even an hour unless some dynamic cooling occurs. If you're getting all rain you may start mixing soon though.

YHM Supercell Posted February 27, 2013 Share Posted February 27, 2013 How about for northeast Scarborough? Am I going to get into the rain too? Hard to say...looks like d.t Toronto is probably in a mix..I would imagine you will start mixing with ice pellets. As for a change over to complete rain? Maybe....probably not I would imagine as you are pretty far from the lake...farthest you will go is probably a mix. Also if Guelph toward Halton hills haven't gone all snow yet...they will very soon.

Sounding like a stuck record, but it is absolutely ripping snow out there. Weight of the snow is really putting pressure on some of the trees.

I'm crossing my fingers that we stay snow the rest of the night...dual pol says yes but who knows what might occur. Link to comment Share on other sites More sharing options...
Chicago WX Posted February 27, 2013 Share Posted February 27, 2013 Don't want to muck up the thread for those on the wintry side of things, but LAF finished with 1.31" of rainfall. Still 36 at my place right now with drizzle and fog. Good luck to the Ontario contingent. Sounds like it may be touch and go for awhile. All the best of luck.

harrisale Posted February 27, 2013 Share Posted February 27, 2013 Still not all snow here. In fact less snow, more rain now than 20 mins ago. Sigh, unless some cold air gets in here soon, I may come in embarrassingly high on my prediction. Been about 2 hours total of rain that models were forecasting to be snow.

Thundersnow12 Posted February 27, 2013 Share Posted February 27, 2013 Probably one of my best snow forecasts. Last night myself and a few others thought it would be fun to predict snowfall totals with the "main snow" at ORD/MDW/DVN/RFD. I went with ORD 4.3" MDW 2.8" DVN 4.0" RFD 3.4"...totals ended up being ORD 4.2" MDW 2.8" DVN 4.2" RFD 3.9". One of my favorite systems I've followed given the tough forecast with marginal thermals but dynamics were able to overcome them. Link to comment Share on other sites More sharing options...

harrisale Posted February 27, 2013 Share Posted February 27, 2013 fwiw, I just ran BUFKIT for YKF and it has us for ZR until 6:00am. Might be time to call it a night.

nwohweather Posted February 27, 2013 Share Posted February 27, 2013 Still rain here while across the border is getting buried. Ahh knew with the 850 temps at 0 exactly it was gonna be close.
