We have scattered showers Tuesday morning in Oklahoma. Temperatures around the state are in the 40s, 50s, and 60s with a cool north wind 10-20 mph.
Later today, rain decreases by mid-afternoon, but the high will only get to 52 degrees. So you can expect a cool and wet day.
Take a rain jacket with you on your travels.
Tonight will be a chilly one as well, but the rest of the week will be mild and sunny.
