Most Extreme Weather on Valentine's Day - From Blizzards to Tornado Outbreaks

Valentine's Day promises roses, chocolates, and romance. Yet, sometimes, Mother Nature has other plans.

February 14th has delivered some of the most treacherous weather in American history. Blizzards have buried entire cities under two feet of snow, stranding motorists for 24 hours on frozen interstates. Tornadoes have ripped through the South, killing dozens during what should have been candlelit dinners. Ice storms have caused hundreds of millions in damage while lovers huddled indoors waiting for power to return.

From 94-degree heat waves in the California desert to -54-degree Arctic blasts in Montana, Valentine's Day weather has tested relationships and survival skills alike. This year's forecast continues the tradition. As couples across the South scramble to salvage outdoor dinner reservations this weekend, a massive storm system is bringing flooding rains and severe weather to millions.

The holiday of love has always had a volatile relationship with the weather. Here's how extreme it can get.
