But maybe a little more snow first. 😉

Just looked at the GFS model this morning and it’s predicting 122mm of raim between Saturday and Tuesday… most of that coming on Monday and Tuesday.

I have little doubt that the later you get into that forecast, the warmer it will be and the less likely there will be snow… but this current freeze is big enough that I would give a pretty good chance for some snow to fall on Saturday and Sunday. It’s already in the Environment Canada forecast as being a possibility.

But even for the meat of the system next week, the GFS is predicting temperatures far below what Environment Canada is saying… only between 0 and 5C. So really. There is an outside chance that this could be a real mess, especially in inland areas and higher elevations.

Ski hills rejoice! The rest of us… just hope for rain. 😉

And just to keep you on your toes, the long long range forecast (Thu Mar 19 to Fri Mar 27) has even more moisture coming our way, at not much better temperatures…

Looks like an interesting start to Spring!


UPDATE
: This mornings GFS model has toned down the amount of precipitation in the forecast. Now it’s looking at only around 70mm between now and next Thursday with not nearly as big an event on Monday/Tuesday.

The catch? It has cut the predicted temperatures in half. Tomorrow and Saturday should be warm, but after that, it’s all hovering around 0C. More snow?!

  1. Rain or snow? It’s a tough call. You’re right, the GFS temperatures are between -2C and 5C, while EC are about 0C to 9C. I think we’ll get a little snow either way, but I did notice that EC was more correct about the high yesterday (12C!) than the GFS. I guess we’ll see.

  2. You’re right, we really blew away the high yesterday. It was just a beautiful day!

    Well, the good news is, in terms of accumulation at least, we’re not supposed to get nearly as much as was previously forecast.

    I think how much snow we gets will ultimately depend on the time of day and the amount of cloud cover we have to lock in that cold air.

    Never a dull moment.

  3. Interesting, It looks like the forecasts are coming closer together now – Environment Canada has lowered the temperatures a couple of degrees and included the chance of snow every day for the next several. The charts you linked to are typical of the patterns we’ve seen all winter this year. Usually those lows hit us dead centre, but this year they’ve been landing most of the moisture to the north of us. Strange year.
