Blindsided

The forecast was calling for colder temperatures and snow today, but when I woke up the sun was shining and there wasn't a hint a snow anywhere. Imagine my surprise when all of a sudden the skies were dark and there was a virtual white-out outside my window. I was wearing just a wind breaker and lightweight clothes last night. When I stepped outside this morning there was an arctic blast blowing through me. I should have grabbed an extra sweater and/or scarf. My forehead still hasn't thawed. When will I be warm again?
