Before we speak about Thursday, let’s delve into Wednesday a bit. Wednesday is warm hot and humid across the entirety of the Province. Multiple areas had highs in the upper 20s to lower 30s as temperatures ran more than 10º above normal in some areas!

On top of that, over the last couple of days, we’ve set some all-time September record highs in a few spots across Newfoundland and Labrador.

Now for today… that warm party is over in Labrador as a much colder air mass moved in overnight. Temperatures fell sharply and much of the Big Land is waking up to reading in the lower teens this morning. Check out the loop of temperatures over the last 24 hours.

Thursday across the Province will see rain over much of the Big Land and cooler temperatures. While on the Island we see areas of showers and thunderstorms, along with another warm and humid day. Highs should be in the lower to mid-20s, but if we get more sun than I think we are going to, mid to upper 20s are possible once again. Futurecast (below) should show this well.

There is a chance of thunderstorms today across much of the Island, particularly for areas west of Grand Falls-Windsor to near Corner Brook.

I’ll have a more detailed weather update this afternoon!

Have a great day!

Good Wednesday morning! And for parents and kids, welcome to the 2023/24 School Year!

As what’s left of Gert, spinning east of Nova Scotia this morning drifts a little more to the west, the wind direction across the Island will turn more southerly over the Island, compared to eastern and northeasterly on Tuesday. This will cause a few things to happen;

• We will see the showers and fog shift from the east coast to the South Coast of the Island
• The air will turn significantly more muggy as we are getting into an airmass that has Florida origins.

Humidex values over a large part of Central and eastern Newfoundland will cruise into the upper 20s to lower 30s today.

Even though the calendar says September, it’s still going to feel like the Dog Days of Summer.

Labrador will see very warm temperatures today as well, with highs across the region soaring into the middle and upper 20s.

The air over the Big Land will be unseasonably warm with highs running over 10ºC above normal in some areas!

This will not last, however, as a cool down is on the way for later tonight and tomorrow as a cold front sinks southward. I’ll have a further update on this, and Tropical Storm Lee for you later today.

Have a good one!

The remnants of Tropical Storm Gert are spinning south of Newfoundland and east of Nova Scotia this evening. That is driving broad, easterly flow, across much of the region today. That setup has brought fog to eastern sections of the Island, while the West Coast, Southwest Coast, and much of Labrador have seen sunshine and highs in the middle to upper 20s, to near 30°!

For tonight we will see scattered showers around this low on the eastern and southern side of the Island. Otherwise, we can expect almost clear skies across the Province. Lows will be into the middle teens on the Island and lower to middle teens in Labrador.

Wednesday, the first day of school in the 2023 school year, will see morning showers in eastern Newfoundland shift toward the south and southwest coast in the afternoon as the wind direction turns from easterly to southerly. Expect highs on the island int he 20 to 26 range, with the coolest readings being found south. It will also be muggy, with humidex values approaching the upper 20s to lower 30s in some areas. Labrador will see highs in the middle to upper 20s, however, clouds will be on the increase in the north and west during the afternoon as a cold front begins to approach the area.

Thursday will see more showers on the Island, along with some sunny breaks and the odd thunderstorm possibility as well. Highs reach the lower 20s. Labrador will see a cooler day, with periods of rain throughout. Highs in the lower teens.

Friday will see showers over parts of the Island, with cooler highs in the middle teens to lower 20s, as the wind turns northerly. Again expect more clouds than sun. Periods of rain will be found in Labrador West.

The weekend, at this point, looks like much of the same.

Good Tuesday morning! The remnants of Hurricane/Tropical Storm/Tropical Depression Idalia are spinning to our south this morning. It’s not currently being monitored by either the National Hurricane Centre in Florida or the Canadian Hurricane Centre in Halifax. This means, at this point, both organizations are looking at it like it is a standard low-pressure centre, which it is at this point.

You can see the circulation spinning, clearly, in the waters south of Newfoundland and Labrador, and it’s backing into the Maritime Provinces. This setup will primarily drive easterly flow across much of the region today. Which will result in cloudy skies and cool temperatures for most of the Island, east of the west coast and south of the GNP. Those 2 areas should see sunshine today, along with much of Labrador.

High today will be into the teens to 20, even with the easterly flow into the region. The HRDPS model does a good job of showing that.

Something else of note is that there will be high waves along and near southern shorelines of the ISland for the next couple of days. Waves just offshore are predicted to be 2 to 3 meters. This may result in higher than normal tides and locally high water for some communities.

The high waves will last through Wednesday before subsiding on Thursday.

Have a great day!

Our Monday will see more of the same, as we close out the new work week. Expect mainly sunny skies across the Province, with highs in the upper teens to mid 20s. The image below does a good job of illustrating the expected high temperatures.

Beyond that, the remnants of Tropical Storm/Hurricane Idalia will move into the region beginning Tuesday. What is left of it will generally work into the Maritime Provinces. It’ll be a weak system and dissipating as it works towards Nova Scotia.

For Newfoundland, the only thing this will do is generate easterly flow as it moves into the waters south of the Island. This means that cooler temperatures, clouds, and showers can be expected for a good bit of the Island beginning on Tuesday and last through Wednesday. Expect highs in the teens.

There are very few forecasts I get to write up for Newfoundland and Labrador that require very little explanation, however, the forecast for the next 3 days is just that!

Expect mainly sunny skies and temperatures into the upper teens to lower 20s on the Island through Monday, and even beyond. While in Labrador temperatures will also be in the teens to lower 20s, but showers will pop up at various times over the next few days. Outside of the showers, expect partly cloudy skies.

Have a great weekend!
