After a wet start to the weekend, Sunday brings a welcome change as rain systems finally push out of the region. However, don't expect a dramatic warm-up just yet — temperatures are set to remain below seasonal averages, keeping the day brisk and unsettled.

Rain Exits, But Clouds May Linger

The morning hours will see the last of the precipitation moving eastward, allowing for gradual drying across most areas. While the heaviest rain is behind us, scattered light showers or drizzle cannot be entirely ruled out in the early hours, especially near lakeshores and elevated terrain.

As the day progresses, cloud cover will slowly break apart, offering occasional sunny intervals. Despite the clearing trend, the atmosphere remains cool and unstable, meaning a brief sprinkle could pop up in isolated spots during the afternoon.

Below-Average Temperatures Hold Their Ground

Highs on Sunday are expected to top out several degrees below the climatological norm for this time of year. This cooler air mass, originating from the north, will keep daytime readings in the mid-to-upper 60s for most locations — a noticeable contrast to the typical late-summer warmth.

Overnight lows will dip into the 50s, making for a crisp evening. Those planning outdoor activities should bring a light jacket or sweater, especially after sunset.

What's Driving the Cool Pattern?

A persistent trough aloft is responsible for maintaining this unseasonable chill. This upper-level low continues to steer cooler Canadian air into the region, preventing any significant warm-up as we head into the new week.

  • Morning rain: Lingering showers taper off by midday.
  • Afternoon mix: Partly sunny skies with a small chance of isolated sprinkles.
  • Temperature trend: Highs in the 60s, lows in the 50s.
  • Wind: Light to moderate from the northwest, adding a brisk feel.

Looking Ahead: When Does Warmth Return?

The below-average temperatures are expected to stick around through at least the early part of the upcoming week. Models suggest a gradual moderation by midweek, with highs slowly recovering closer to seasonal values by Wednesday or Thursday.

Until then, residents should enjoy the cooler, drier conditions — a brief reprieve from typical summer humidity. For the latest updates and any changes to the forecast, stay tuned to your local weather authority.
