Two years ago today ( March 14th ) began the stretch of epic warmth which would result in the warmest temps this region has ever seen in the month of March for alot of places. Here the high was 78.. Would stay in the 70s and be capped off with low to mid 80s for 3 days followed by another 70+ day before it cooled off.

 

For those who wish to look back on it here is the link to the record thread for most of the records broke.

could also be that less snow makes it thru the evergreens and onto the ground...so less accumulation under evergreen trees.

 

Good point. Around most pine trees there is a ring of grass around them, so I think it's both factors.

 

Already 39° here.

Biggest storms this season for Toronto:

 

December 14 - 11.2"

Feb 5 - 8.7"

March 12 - 7.2"

 

Three 6"+ers including a 10"+ is a damn good for one winter. Just need another 1.5" to get to 60" on the season and I can safely bump this winter up to an A- grade. Notwithstanding that we left 15-20" on the table with those two storms around New Years.

It's kind of strange, the forests that are not evergreens and are more sun filled have more snow. But around evergreens the snow is completely gone - both under the trees and around them. Actually it's not that strange - the dark green absorbs more rays during the day. Windy and exposed areas are the prime areas where the snow has mostly melted out. In fact before it got cold yesterday afternoon there was mud to be had in sunny places.

 

Temp leveled off here and should start rising soon.

I was bored :popcorn:

"Common sense says that the shade of a tree will help retain snow, and snow exposed to sunlight in open areas will melt. This typically is the case in regions where winter temperatures are below freezing, such as the Northeast, Midwest and most of central and eastern Canada. But in Mediterranean climates – where the average winter temperatures usually are above 30 degrees Fahrenheit – a different phenomenon occurs. Snow tends to melt under the tree canopy and stay more intact in open meadows or gaps in a forest.

This happens in part because trees in warmer, maritime forests radiate heat in the form of long-wave radiation to a greater degree than the sky does. Heat radiating from the trees contributes to snow melting under the canopy first.

“Trees melt our snow, but it lasts longer if you open up some gaps in the forest,” Lundquist said. “The hope is that this paper gives us more of a global framework for how we manage our forests to conserve snowpack.”

Looked (and felt) like late January yesterday with the new snow and 19F high. Despite this there was still some melting, never underestimate the power of the March sun.

 

Up to 41 so far today, and mainly sunny so we'll likely burn off a ton of snow by the end of the day, especially the powdery stuff from the second half of the storm.

Anybody around here attending this tomorrow?  Going to be a lot of focus on the November 17 outbreak.

I wish was going. I was originally scheduled to work, now I don't have to but registration is closed. Jim (Kokomowx) usually attends if I'm not mistaken.
