Better hurry outside while you still can.
Calgary weather may be providing clear skies, warm sun, and highs of 25°C today, but none of those things will be sticking around long – rain is in the forecast for the rest of the weekend.
Saturday may start off with skies of blue, but as the day progresses things will begin to gray, with showers opening up overnight.
Sunday is much the same, getting to lows of 0°C going into the weekend, making for a high possibility of snow in the first few days of October.
But all that rain is days away from now. Enjoy the warm sun and clear night sky today, and worry about the snow boots and umbrellas later.
