Newfoundland Forecast Updated Sunday, January 19, 2024 @ 8:30 PM
TONIGHT’S FORECAST
Rain, drizzle, and fog across the Island tonight should lighten up towards dawn. Most areas will see 10-20 mm rain tonight, but up to 30 mm on the Burin Peninsula, and 40-70 mm on the South Coast, from Port aux Basques to Burgeo. Temperatures rise through the night across the Island, between 6°C to 10°C, except +3°C to +5°C on the Northern Peninsula. South-southeast winds will gust 50-80 km/h across the Island, becoming light by midnight on the west coast and Northern Peninsula; elsewhere, winds should become fairly light by dawn Monday.
MONDAY’S FORECAST (January 20)
A second system quickly moves across the Island in the morning and afternoon, bringing more RDF, which should end before the evening. Temperatures peak between 8°C and 13°C (a bit cooler on the Northern Peninsula) in the morning and early afternoon, but they will start to fall in the afternoon on the west coast behind the associated cold front, causing precipitation to change to flurries on the west coast late afternoon. Southerly winds increase across the Island in the morning, with gusts of 50-80 km/h, which will shift to the southwest in the afternoon.
Monday night, onshore flurries and snow squalls will develop along the west coast, from Port aux Basques to Port au Choix in the evening. Flurries also develop along the South Coast and Burin Peninsula overnight. Lows Monday night from -3°C to -6°C in the east, -6°C to -10°C in central NL and the South Coast, and -8°C to -12°C on the west coast and Northern Peninsula. Southwest to west winds will still gust 50-80 km/h, giving wind chills of -10 to -15 in the east, -15 to -20 in central NL/South Coast, and -20 to -25 on the west coast and Northern Peninsula. The combination of the squalls/flurries and these winds will create near-blizzard conditions, especially on the west coast and Northern Peninsula Monday night.
TUESDAY’S FORECAST (January 21)
Snow squalls continue all along the west coast, southern Newfoundland, the Burin and Avalon Peninsulas. For central NL, the northeast coast, Terra Nova, Clarenville, and the Bonavista Peninsula, lots of sunshine Tuesday. Temperatures do not move much from the morning lows, but values could drop a few degrees in the afternoon. Westerly winds will gust 50-80 km/h, giving whiteout conditions in the areas mentioned above with the squalls. The squalls continue Tuesday night, but should ease up Wednesday. Wind chills remain -15 to -25 Tuesday and Tuesday night.
As for snowfall amounts, 20-40+ cm is possible for the west coast, from Port aux Basques up to Gros Morne. It is in the Gros Morne area that could exceed 50 cm through Wednesday. Significant amounts are also likely on the south coast and Burin Peninsula.
