Hey Folks,

Well as far as a first Snowfall goes... the shot of Snow across the Metro area and parts of the Avalon last night was a good first taste. As advertised, this system was tough to nail down, with the various forecast models flip flopping right up until the very end. In the end, it seems amounts were in that 8-15 cm range for most of the Metro area, but pretty variable between the highest and lowest elevations. St. John's Airport picked up 17 cm of Snow, while 20 minutes down the road, a few of my colleagues measured closer to just 5 cm in CBS!
 
This is certainly the time of year when you can see differences between high & lower elevations in terms of snowfall. With yesterday's storm in particular, the Snow was sticking to the ground and accumulating near the airport by 2pm, while here near the CBC it took until 4:30 or so and lower elevations took even longer than that. Temperatures at the surface were ABOVE zero in the Metro area and temps cool off more quickly in those higher spots. CBS being right along the "warmer" water of Conception Bay & downsloping Northeasterly winds were no doubt a factor yesterday as well. However, as we move into the Winter season, the ground gets colder, our temperatures get colder & we all get some snow on the ground, these differences become smaller.
 
SNOW SPREADS NORTHWEST
 
Our system is slowly moving North over the next few days and has already been spreading Snow & Wind into Central, Western & Northern Newfoundland as well as Southeastern Labrador  today. Overnight & into Friday on the Island, the periods of snow will slowly come to an end, while the winds are going to increase and Snow Squalls are really going to begin firing up along the West & South Coasts of the Island!
 
 
THE NEXT 36 HOURS
 
 
LONG RANGE
 
As mentioned, winds will stay very gusty across the Province tomorrow, especially across the Island and for Coastal Labrador. By Saturday, an area of High pressure will be parked over the Maritimes. The breezy Northerly flow around that high will mean a chilly Saturday for NL. The squalls should be coming to an end, but onshore flurries will continue for the West Coast through Saturday.
 
High pressure moves over the Island on Sunday bringing some Sun and lighter winds, which means temperatures will be a little warmer, but likely still hovering near freezing. In Labrador a system approaching from the West will bring clouds and flurries, but also a Southerly flow and warmer temperatures for you.
 
As of now, that system looks set to will move into Newfoundland on Monday with warmer temperatures and showers to start the week.
 
LONG RANGE GFS FORECAST MODEL
 
 
As you can see, following our early week system, forecast models are showing another system set to arrive mid next week... with even warmer temperatures and strong Southerly flow.
 
The overall theme for next week certainly looks "mild".
 
Speaking of next week, I'm off for a week of R&R, Lee Pitts will be pinch hitting for me here in the Weather Centre... and be sure to check out the Live Blog at www.cbc.ca/ryansnoddon for the latest from Rodney Barney.
 
Talk to you in December!
