Slave Lake, Alberta can shake off the wet start Friday and look forward to a warm, sunny weekend. Environment Canada forecasts temperatures climbing from a high of 20°C on Saturday to 23°C on Sunday, well above the June normal high of 19°C. That means ideal conditions for gardening, outdoor fun or any plans that got sidelined by morning showers.

Friday will be the day to get through first. The morning will see a mix of sun and cloud with a 30% chance of showers, and winds are expected to pick up from the northwest to 20 km/h near noon. The high will reach just 16°C. A UV index of 6, or high, is also in the forecast, so sun protection is a good idea even with mixed skies.

Once the system clears out, the weekend shapes up to be mostly sunny and clear. Saturday night’s low is expected around 8°C, with Sunday night dipping to 11°C. The average high for this time of year sits at 19°C, meaning Sunday will be roughly four degrees above normal.

Folks planning ahead should note that the dry stretch does not last long. Tuesday is expected to bring cloudy skies and a 60% chance of showers, with the temperature dropping back to 17°C.
