Tuesday evening update; rain and showers spread into N.L. Wednesday afternoon

By Eddie Sheerr — 2 years ago

Tonight’s Outlook

Expect quiet conditions across the Island, under partly to mostly cloudy skies. Temperatures will be on the cooler side, falling into the lower to mid-teens. The exception will be in Central and parts of the interior, where lows will dip into the upper single digits.

Labrador will see equally quiet conditions to start the overnight, however, rain and/or rain showers will arrive in the west before sunrise. Lows will be in the lower teens. Areas of fog will be found on parts of the north coast.

Wednesday/Thursday Outlook

Wednesday will start quietly across the Island, with some sunshine for the eastern, northern, and central areas. The West Coast and Southwest Coast, along with the South Coast, will generally begin the day cloudy. Showers will arrive on the south and southwest coast by mid to late afternoon. Those will spread north and arrive on the West Coast and possibly into Central during the evening. Highs in the mid to upper teens across the board.

The rain will spread east and north Wednesday night, setting much of the Island up for a rainy day Thursday. The rain will be heavy at times for many areas.

Labrador will see the rain spread in late tonight and it will take hold during the day Wednesday for western areas, and about as far east as Upper Lake Melville. The rain will taper to showers Thursday for the Big Land. Temperatures tomorrow and Thursday will be cool, in the mid to upper teens. Parts of the coast will be dealing with fog.

Rainfall amounts will be moderate for most areas with a widespread 15-30 mm on the way between later tonight and late Thursday. The highest amounts look to be over portions of Labrador West and southern areas of the Island.

*Rainfall forecast | August 8 thru August 11, 2023*

The rain coming in is in response to an area of low pressure moving into the region. This will bring some gusty winds to the Cabot Strait and the Channel-Port aux Basques area. A Wreckhouse Wind Warning is now in effect for Wednesday afternoon into Thursday morning for gusts as high as 110 km/h in the area.

Strong winds and high waves are also expected in the Cabot Strait between Wednesday and Thursday, and because of that Marine Atlantic has issued a weather advisory for that time frame. They are thinking the crossings Wednesday into early Thursday may be canceled. Be sure to check with them if you have a crossing in that window.

Tuesday update; clouds now, sunshine later!

By Eddie Sheerr — 2 years ago

Tuesday morning has started off on the cloudy, and even drizzly side, for many areas of the Province. The webcam images below from across Newfoundland and Labrador illustrate the point rather well.

As we move throughout the morning and into the afternoon, the general trend in the cloud cover should be a decreasing one. In fact, over the next several hours skies should turn partly cloudy to even mostly sunny across the bulk of the Province. That will happen first in western Labrador and southern Newfoundland and a bit later everywhere else. The loop of future cloud cover shows this rather well.

Temperatures this afternoon will be very similar to yesterday, where much of the Province peaks in the mid-teens to lower 20s. The warmest readings will be found in southwestern Newfoundland and interior and western parts of Labrador. While the coolest readings will be found along the coast of Labrador and near and along the north-facing shores of the Island.

Beyond today, we see an area of low pressure arrive between Wednesday and Thursday. Initially, this will spread rain into Labrador West tomorrow, along with southern areas of the Island. But more of the rain moves in Wednesday night and sticks around through Thursday.

And you can bet with the increased rain chances, will come more cloud cover and not a big change in our temperatures. There are signs of a return to the warmth, but it is looking like that will take a few days. As of now it looks like later this week or by the weekend the 20s are back in play.

Have a great day and I’ll have your next update this afternoon!

Monday evening update: Sunshine returns Tuesday for much of the Province

By Eddie Sheerr — 2 years ago

Tonight’s Overview

The showers will continue across parts of eastern and central Newfoundland into the overnight while becoming much less numerous on the West and South Coasts. Skies will clear out over the southwest corner of the Island, while most other areas remain in the onshore, northerly flow which tends to bring in an abundance of low cloud. Lows of 9 to 12. The gusty winds from Notre Dame Bay to the East Coast of the Avlaon will remain up overnight, before slowly subsiding during the day on Tuesday.

Labrador will see partly cloudy skies, with lows in the 8 to 12 range. Pretty boring… I know!

Tuesday’s Overview

Generally a quiet day across the Province, with a mix of sun and cloud. Some showers will crop up over interior Labrador and drift toward Churchill Falls. That’s about it for precipitation. Highs of 16 to 22 across the region.

Wednesday will see a dry start, but showers move into Labrador West in the afternoon, along with southwestern and western Newfoundland. Highs will again be into the mid-teens to lower 20s for highs. Thursday looks like a rainy day across the board, as an area of low pressure swings in. The rain will taper for most areas by Friday morning. The rain will be significant for some locations.

Northerly flow starts the new workweek

By Eddie Sheerr — 2 years ago

An area of low pressure to the east of the Avalon Peninsula dominates today’s weather pictures. This low is part of the system that brought bouts of heavy rain to the southern and eastern sections of the Island on Sunday. Which, if you were like me, made for a not-so-great ride on the highway. The map from windy.com helps visualize the situation.

The low to our east will generate lots of northerly/onshore flow across much of the Island and parts of Labrador today. This pattern generally brings cool temperatures, clouds, and showers to areas near and on north-facing shores and today will be no different. In today’s case, the showers will be most prevalent over coastal areas of central and eastern Newfoundland but will be possible as far south as the South Coast. Coastal Labrador will also see some showers to start the day, but they should become less widespread by the early afternoon. The loop from the RDPS model (below) illustrates this point rather well.

The sun will shine at times today but will become more prevalent across much of NL this afternoon as the showers ease and the skies try to clear. However, the clouds will roll back in overnight as the northerly flow continues.

Temperatures will peak in the mid-teens to about 20º across the Province to start the week. We will see a bit of a warming trend for the first couple of days, however, a large area of low pressure will swing in for Wednesday, which brings our next chance of widespread, significant rainfall.
