Here are my updated thoughts on snowfall totals for Newfoundland.

The heaviest snow will be for the northern Avalon and parts of the Bonavista Peninsula.

Wind gusts of 70-100 km/h will combine with snow to create blowing snow & white out conditions at times.

#NLwx #NLtraffic

Winds will also be gusty/strong, especially for southern, eastern & northeastern Nfld overnight Tuesday night, Wednesday & Wed evening.

Gusts will be NE, to N then NW with gusts 70-90 km/h, with near 100 km/h in exposed coastal areas.

#NLwx

Here are my thoughts on snowfall totals:

It's worth noting that snow will be wet & possibly heavier to clear, especially east.

The Avalon may experience a lull in the snow mid-late AM & afternoon before reintensifying late aft or eve.

Some tweaks may be needed tomorrow.

#NLwx

Another low is set to pass to the south & east of Newfoundland beginning Tuesday eve, continuing to Wednesday overnight or early Thursday AM for some.

The heaviest snow will fall in the east, particularly the northern Avalon.

Snow will be accompanied by strong winds.

#NLwx

It is increasingly likely that eastern Nfld will see a snow event on Tuesday night into Wednesday.

Overnight models show a bit more agreement with the RDPS shifting farther west with the low's track.

Exact amounts & timing still remain in question, but get shovels ready!

#NLwx

A retrograding low will bring continuous light-moderate snow to the NE coast, Bay of Exploits, Baie Verte, eastern Nfld & coastal Labrador.

This will occur tonight & Monday for Labrador. Monday to Wed & possibly late week for Nfld.

Expect 10-20cm+, higher amounts likely.

9:05am radar showing snow just to the southeast of the Avalon as a potent low misses Newfoundland offshore.

The Avalon should see some periods of light snow this afternoon and evening, with 2-5cm or so.

#NLwx

The back end of the steadier snow is now over Trinity Bay and slowly shifting southeast.

St. John's Airport #YYT reporting 42cm as of 11:30pm.

St. John's East snowfall: 42.2cm.

#NLwx

St. John's Airport adds 3cm in the last hour, putting the total 33cm as of 5:30pm.

Snow has restarted on the Avalon Peninsula. Meanwhile, it continues for points west.

Airport snowfall through 2:30pm:

St. John's #YYT: 29cm
Gander #YQX: 14cm

#NLwx

I'd suggest another 15-20cm.

St. John's Airport #YYT reporting 13cm as of 7:30pm (+5cm snowfall in the last hour).

St. John's east snowfall: 17.8cm as of 7:30am.

Snow should begin in St. John's shortly after midnight.

Snow is also underway for the Burin Peninsula.

#NLwx

10pm radar update: Snow is underway for the southern Avalon and Burin Peninsula and is spreading northward.

#NLwx

8:35pm radar update:

Snow is encroaching on the southern Avalon & Burin Peninsulas.

Snow is still on track to spread north through Newfoundland tonight and through the overnight.

#NLwx

Gonna be fun one to measure lol

So we can have more of it...😆

5:41pm radar showing snow showing up at the edge of the radar south of Newfoundland.

#NLwx

Yeah it will, especially into the afternoon as the temperature gets to around zero.

That's accurate. Maybe a snowmaggedon light.

Snow will combine with strong winds, especially in the south and east.

Southern, eastern & NE Nfld will have gusts 70-100 km/h Monday morning to Tuesday morning.

Reduced visibility and white out conditions are expected with blowing snow.

#NLwx

Here are my thoughts on snowfall totals for the winter storm beginning overnight tonight, continuing into Tuesday morning.

The snow/rain/ice pellets mix line may reach southern parts of Metro Monday afternoon.

Blizzard conditions are expected for eastern Newfoundland.

#NLwx

2. Snow will be heavy at times overnight and through the day Monday, especially in the morning hours.

Snowfall rates will be 4-8cm/hr at times in eastern Nfld.

The southern Avalon will change to ice, freezing rain & rain Monday aft, then chg back to snow Monday evening.

#NLwx

1. Our major winter storm will begin impacting #NLwx overnight (near midnight to 5am or so depending on location).

Snow begins in the south & east first, spreading north through the overnight.

Snow will wind down for central & eastern Nfld early-mid Tuesday morning.

⚠️🟠=NEW=🟠⚠️Orange winter storm warning replaces the watch for the Avalon & Burin Peninsulas.

Snowfall: 35-50cm+

Rainfall: 5-10mm, mainly for the southern Avalon.

Max wind gusts: E, to NE to N 80-100 km/h.

Timeline: Overnight Sunday night to Tuesday afternoon.
