February 2021 Forecasts and Discussions

When do these arctic outflow winds come? Usually Squamish is howling with them. I guess the front is not here yet? Global news doesn't even mention wind‍♀️

Some light outflow tomorrow, but you'll probably start to notice it by Tuesday evening into Wednesday.

Gets really gusty by Thursday.

18Z GFS hinted at a reload in the long range. But we all know how reliable the long range has been this winter.

If memory serves me right I think in 08 the forecasters kept getting surprised with the arctic reloads after every snowfall.

Who knows, maybe 0z will dig its heels in

Judging by the 18z RGEM, there'll be a pullback. It was less aggressive in retrograding the PV lobe into AB and eastern BC by Wednesday.

Edit: Looking at the meteogram again, it looks like winds are mostly calm when the snow is falling but become gusty as the precipitation eases and shuts off.

00Z RGEM shows blizzard conditions in the valley Wednesday morning with 10cm of snow and NE winds around 50 km/h while the snow is falling. WeatherPro!!!

00z RGEM shows light snow across the lower mainland on Wednesday morning.

Yup. That event went on longer then initially expected if I understand and recall correctly. Models kept trying to warm us up too soon. Fairly common.

What do you mean by pullback?

With arctic outflow winds hopefully lower mainlanders get some of that.

Will someone please think of us Southwesterners

What do you mean by pullback?

Less extreme cold.

What do you mean by pullback?

No more -23 850s at YVR. Something more reasonable like -17 maybe.

Yeah and they're usually right 99.9% of the time for warming us up. Love it when the .1% verifies. #surprises

00z RGEM shows clear skies Wednesday night which could set the stage for some fairly impressive lows by Thursday AM if there's some snowcover.

Well who actually believed we would get the 850 temperatures down to -23 at YVR?

[VanCitySouth]

Might not be reading this right but no material difference between 18 and 0z GFS to my eye through 72 hours

Edit: bit of a jump north on the moisture through hour 90
