It was a long & windy road as usual but here we are - one last round of totals from me (but not necessarily from Ma Nature).

Snow continued through the afternoon and evening here which has coated everything white once more. YOW surpasses 300cm, breaks the daily record from '97 and moves a spot further up the top 10 list. YYT also pushes over the 400cm mark so that goal is met as well, by any messy means necessary.

All of this icing and crow on the side will keep me busy I'm sure biggrin.gif

YYJ Victoria, BC - 58.3cm / 39cm (+0)
YVR Vancouver, BC - 69.6cm / 37.7cm (+0)
YYC Calgary, AB - 95.8cm / 84.1cm (+0)

YHM Hamilton, ON - 99.4cm / 146.9cm (+0)
YYZ Toronto, ON - 80.6cm / 103.6cm (+0)
YOW Ottawa, ON - 303.7cm / 208.2cm (+10)
YUL Montreal, QC - 231.9cm / 194.8cm (+2.6)
YSJ Saint John, NB - 312.4cm / 217.8cm (+0)
YYG Charlottetown, PEI - 328.4cm / 260.5cm (+0)
YHZ Halifax, NS - 394.9cm / 203cm (+0)
YQY Sydney, NS - 445.5cm / 258.6cm (+5)
YYT St. John's, NL - 406.5cm / 302.8cm (+10)

Kind of a swan song to your tenure here.

Light to moderate snow all afternoon here but very little has been able to accumulate with temps hovering right at the freezing mark. Hard to say what numbers the airport will spit out tomorrow AM.

12z ECMWF continues the idea of a stormy/wet pattern for both the west coast and a fairly sizable portion of the east into the first third of April with sporadic breaks between disturbances.

True! They also seem quite enthused by the winds though they are more a moderate breeze by NL standards. tongue.gif

Flakes flying with temps just above the freezing mark so nothing really sticking yet. It will take 6.3cm by tomorrow at the airport to make it to 300, excluding the 5.9cm in October since I'm dealing with NDJFM.

I see TWN are on a jolly over here, think the trip was planned when snow totals were looking more epic here so a bit disappointing I imagine. They seem to have alot of clips on social media of the sea ice washing ashore, it's not that common to see it wash right ashore here in and around St John's, last time I think was March 2012, so not a complete wasted trip.


Never a bad time for a trip to the Rock, except maybe that one horrendously cold July a ways back laugh.gif

Their team can have an extended stay and wait on that next low maybe.

Yes do you think it must have bought just enough warm air with it to spoil the party here as if you look at how far SE the center of the low is it would normally be an all snow event with that track, not the snow/rain/snow way it played out. I still think the GGEM seemed to call it more right a few days ago.


Well then let's hope the regional Canadian remains on the right track with the next changeover too smile.gif

And yeh I will be a bit disappointed if we at least don't go over 400cm after all this. laugh.gif


By any means necessary happy.gif

If we pass 300 and you pass 400cm on the final NDJFM tally then it will have been a worthwhile last stand and a lot of icing on the cake. Maybe not to the point of YHZ or YQY but Halifax made their mark with the giant snowman a while back.

THE MODEL AND ENSEMBLE GUIDANCE CONTINUES TO INDICATE A PERSISTENT
NORTHEASTERN PACIFIC TROUGH. THE DOWNSTREAM IMPACTS ARE
MANIFESTED IN AN AMPLIFYING WESTERN US TO HIGH PLAINS RIDGE AND
DOWNSTREAM DEVELOPMENT OF AN EASTERN US TROUGH.

THE FIRST UPPER TROUGH WILL CROSS THE MS VALLEY INTO THE OH VALLEY
MON AND THE MID ATLANTIC TO NEW ENGLAND TUE...MOVING OFFSHORE
AFTERWARD. THE MODELS HAVE TYPICAL TIMING AND AMPLITUDE
DIFFERENCES SO A BLEND OF THE 12Z GFS/ECMWF AND ECMWF ENSEMBLE
MEAN WAS USED FOR THE FORECAST.

THE SECOND UPPER TROUGH IS REFLECTED BY SHRTWV ENERGY ENTERING THE
NORTHWEST SUN-SUN NIGHT AND CROSSING THE ROCKIES MON AND PLAINS
TUE AND GREAT LAKES/OH VALLEY WED. THE DIFFERENCES INVOLVE TIMING
AND AMPLIFICATION. THE 12Z GFS AND ECMWF AND ECMWF ENSEMBLE MEAN
FORMED A NICE CLUSTER AND A BLEND OF THESE SOLUTIONS WAS USED.

THE MAIN CHALLENGE ALONG THE WEST COAST LATE IN THE PERIOD WILL BE
WITH SHRTWV IMPULSES STREAMING AHEAD OF THE DEEPENING NERN PAC
TROUGH.

THE SOUTHEAST SHOULD SEE ABOVE NORMAL TEMPS DAYS 3-5 AND THEN
SWITCH TO BELOW NORMAL TEMPERATURES DAYS 6 AND 7 AS THE EASTERN
TROUGH BUILDS...WITH BELOW NORMAL TEMPERATURES DEVELOPING FROM THE
GREAT LAKES TO THE OH VALLEY AND APPALACHIANS AS WELL. THE UPR
RIDGE BUILDING INTO THE WEST NEXT WEEK SHOULD LEAD TO A
SIGNIFICANT WARMING TREND OVER THAT REGION WED-FRI.

Sounds and looks like a tropical storm here, 90kmh winds with heavy sideways rain...just very cold rain with temps around 1c so certainly not feeling tropical when you step outside! Fortunately seems the freezing rain didn't last too long overnight


There is some tropical influence at work since I believe what was once invest 90L was absorbed into the circulation.

QUOTE
After all the promise for this earlier in the week, hoping we can at least salvage something from this later today when it is meant to change back to snow, the RDPS has up to 15cm, but the way this has trended I wouldn't be surprised if we only got a minor amount.


3.5cm to make it to 400. YQY had the sweet spot by the looks of it.

YOW needs a recharge with the snow depth reading at 3cm, not to mention we'd have to make it to April 5th intact to achieve 4 months of snowcover and that's questionable beyond this system. Yesterday makes it day 116 in the streak anyway.

The daily record snowfall for today is 8.2cm (1997) so we'll see if that can be upset by tomorrow.
