There is some slightly better news in the forecast for Wednesday and Thursday across parts of Newfoundland, especially compared to what we dealt with on Tuesday. While we are not suddenly flipping into full sunshine and warmth, the atmosphere will dry out enough for many areas to lose the thick “pea soup” fog and steady drizzle that’s been hanging around.
A look at the moisture content in the atmosphere — what meteorologists call precipitable water — shows noticeably drier air wrapping into much of Newfoundland and Labrador by Wednesday morning. That dry air won’t completely clear the skies, but it should help lift ceilings, thin out the fog, and allow for at least a few sunny breaks inland across eastern and northeastern Newfoundland.
The biggest improvement Wednesday will likely be found away from the immediate coast. Parts of central, southern, and southwestern Newfoundland should actually see a fairly decent day with brighter skies at times. Meanwhile, the Burin, Avalon, and Bonavista Peninsulas will still hold onto some drizzle and fog, though it should not be quite as dense as what we’ve been seeing recently.
Thursday follows a similar theme, and in some places may actually turn out fairly pleasant. Areas just inland from eastern and northeastern shorelines could see sunshine and temperatures climbing into the low teens. St. John’s, however, will likely stay much cooler near 5 degrees with low cloud and fog lingering nearby.
The key Thursday forecast detail is that the thickest fog may become confined mainly to east and northeast-facing coastlines, including parts of the Avalon, Bonavista Peninsula, and Northeast Coast. In other words, if you can get even a short distance inland or toward south-facing areas, conditions may improve dramatically. Thursday could be a great day for whale watching in St. Vincent’s!
Unfortunately, this nicer stretch doesn’t last very long.
By Thursday night, another system approaches from the south, bringing increasing cloud, drizzle, fog, and eventually more widespread rain into Friday. That unsettled pattern may linger right into Saturday before another low potentially arrives later Sunday into Monday.
And yes… there are even hints from some guidance that a few higher elevations or localized areas could mix with wet snow early next week. At this point, that risk appears limited, but it says a lot about how stubbornly cool this pattern remains for late May.
The reason for all of this is a classic omega block setting up across North America. This is a stagnant weather pattern where a strong ridge of high pressure becomes trapped between two low-pressure systems, forcing areas like Newfoundland to remain stuck under cool, damp, unsettled weather for days at a time.
Labrador continues to fare much better overall in this setup. While temperatures there may run a bit cool at times, much of Labrador will see more sunshine, drier air, and highs reaching the teens through next week.
As for Newfoundland, temperatures remain below seasonal for several more days, though there are some signs conditions may slowly improve after Monday or Tuesday of next week.
The next forecast update will be posted bright and early Tuesday morning!
