I am a bit concerned about the potential for prolonged & significant amount of freezing rain for eastern & parts of central Nfld from Tuesday into Wed & psbl Thu AM in central.

Eastern: Showers > frz rain > rain.

Central: Snow > ice > frz rain.

Western gets all snow.

The bad news? A quick shot of snow tonight for many in Nfld.

Parts of the SW, south coast & Burin Pen will stay as or mix w/rain.

The Avalon should change to showers in the AM.

Good news? It warms tomorrow & snow melts.

Generally 2-5cm, with pockets of 5-10cm for some.

1. I wish tomorrow's #NLwx was an April Fool's joke!

However, snow moves into SW & western Nfld after midnight, reaching eastern Nfld by morning. Snow begins in Metro by 8-9am.

Snow may mix w/ice pellets & frz rain, esp for the Burin & southern Avalon tomorrow evening, ending tomorrow night.

2. Snowfall amounts will be clearer tomorrow. However, areas from SW Nfld, thru the south coast, Burin & Avalon, are likely to receive up to 15cm of snow, possibly higher.

A slight shift north or south will chg totals.

Ice & freezing rain mixed also determines totals.

#NLwx

1. The next #NLwx system arrives Tuesday night (or Wed AM for areas further north).

Snow will be heaviest for southern Nfld from PAB to the Avalon.

Some areas may mix w/or chg to a period of ice pellets, frz rain & maybe showers for extreme southern areas.

Precip ends Thursday morning.

An appetizer system rolls thru this eve, tonight & ending early Tue AM.

Snow will change to or mix with rain, particularly south, and along the coast.

Snowfall will generally be 2-5cm, except pockets of 5-10cm for west, south & SW Nfld. Near 15cm for the Burgeo Hwy.

#NLwx

Another consideration for the current temperatures is that they are for the most part within the climatological normal for lows for Mar 28. So at the moment, we're probably closer to normal as we're only a few hours off the overnight lows. That will change later today as it refuses to warm up #nlwx

Precipitation has gone over to freezing rain at noon for the northeast Avalon.

#NLwx

Here are my thoughts on snowfall totals for tonight into tomorrow & tomorrow night

The heaviest snowfall will be for eastern, southern & parts of central Nfld

Expect blowing snow & reduced visibility with gusts to 60 km/h tonight & Tue AM. Gusts 80-100 km/h Tue aft/night
