Rain and wet snow are on the way for Eastern and Central tonight, and May 2-4 looks half decent

Rain tonight

An area of low pressure will pass over the Isthmus of the Avalon Peninsula tonight, splitting Placentia and Trinity Bays. This low will drive some heavy rainfall over the eastern half of the Island, with the heaviest rain falling on the Avalon Peninsula. By Thursday morning, a widespread 15-30 mm will have fallen over the easternmost Peninsula, with lesser amounts in the west. The West Coast will see virtually no rain overnight.

Snow tonight?

As the low moves into the North Atlantic, the rain will change to wet snow over portions of central and northeastern Newfoundland after midnight. The snow will end as flurries or showers by 7 or 8 AM Thursday. Some areas will have a light snow accumulation on grassy and unpaved surfaces. I suspect most roads will remain wet as temperatures will generally remain a degree or so above the freezing mark in locations that see the snow. The snow will not reach the Avalon.

Snowfall forecast between late tonight and 12 PM Thursday

Thursday, Friday and the Long Weekend

Behind the area of low pressure, Thursday will be a decent day across much of NL. However, there will be some showers over central and eastern portions of the Island during the afternoon. Specifically during the hours of 12 PM to 6 PM. Thereafter skies should clear, setting the stage for a sunny and mild end to the week!

The Long Weekend

Some of the warmest air so far this year will grace the Province for the holiday weekend. Expect highs on the Island to near 15 to 20 on Saturday, with areas of the southwest cooler, due to onshore flow. It should be a sunny day as well! Labrador will see highs a bit cooler, between 10 and 15, with a few showers in the west by afternoon.

Sunday will see late-day rain for the eastern, southern, and western sections of the Island, and Labrador. Highs will again be mild.. reaching the low to mid-teen in Labrador and mid to upper teens on the Island.

Monday will see scattered showers over the bulk of the Province, with highs in the teens on the Island and between 5 and 10 in Labrador.
