Wednesday, May 23, 2018, 8:17 PM - Snowfall WARNINGS are in effect across parts of Newfoundland with a system that could dump up to 30 cm through Thursday. In fact, there's the potential for some amounts to actually EXCEED 30 cm over higher elevations. Elsewhere in the province, it's heavy rain and gusty winds that have prompted special weather statements. More on who sees what, below. 

A cruel comparison? 

All this talk of snow shovels and dangerous travel in Newfoundland while temperatures spike to summer values in Ontario and conditions actually get uncomfortably HOT in the Prairies this week. Welcome to spring in Canada. 


WEATHER HIGHLIGHTS:

  • Transition to snow is underway for north Newfoundland as the front slows over the island. Cold air will continue to pump in from the northwest behind the front through Thursday.
  • Fine line between rain and snow across island; Avalon expected to see 40 mm of rain, 20-30 mm for St. John's.
  • 30 cm snowfall expected for Gander by noon Thursday.

SNOWFALL WARNINGS FOR CENTRAL NEWFOUNDLAND

Following Wednesday's rain, an intensifying low pressure system and the arrival of a cold front is going to transition the rain to snow across central Newfoundland overnight.

And we're not talking about a light dusting either as areas such as Grand Falls-Windsor, Bay of Exploits, Bonavista North, Gander and vicinity and Terra Nova are at risk for seeing between 15-30 cm!

"Typically with late season snowfalls, accumulations are highly variable from one area to another depending on elevation and proximity to the coast," says Environment Canada in the warning. "As a result, there is potential for amounts to exceed 30 cm over some higher elevations while lower elevations and areas right along the coast could see lower amounts than forecast."

Drivers are being warned of accumulating snowfall on highways and roads and to maintain a safe following distance if visibility is reduced. 

HEAVY RAIN FOR THE REST

The intensifying low brings the threat for heavier rain across much of the rest of the province with up to 45 mm possible in the hardest hit places. 

"Additionally, strong northerly winds gusting to 80 km/h will develop by Thursday morning and persist throughout the day, possibly stronger over the northern Avalon Peninsula," EC says. 

Heavy rain and snow are expected early Thursday, but conditions are expected to improve by the end of Thursday.

"A very chilly pattern develops through the weekend however," says Weather Network meteorologist Dr. Doug Gillham. "Conditions become unsettled once again for Friday and into early Saturday with the potential for a mix of rain and snow showers for the interior of Newfoundland."
