Polar Vortex Begets Baby Boom?

Nine months after the Polar Vortex covered a good part of American with freezing cold, there appears to be a baby boom, according to one unverified news story:

MINNEAPOLIS (WCCO) – It’s been nine months since our bitter cold winter ended.
Now, delivery rooms are bracing themselves for a Polar Vortex baby boom.
All 39 maternity rooms and the NICU are full this weekend at a Des Moines hospital.
Doctors believe the baby bonanza is a result of the polar vortex last December and January.
In case you forgot, it was one of the snowiest and coldest winters on record.
August and September are usually the busiest months for maternity wards, draw your own conclusions why.

I'm holding out for more data.

August and September are usually the busiest months for maternity wards

This sounds more like people getting it on during the holiday season than people getting it on because of particularly cold winter weather. The latter, if it were the cause of a baby boom, would have mothers hitting the maternity wards in October and November.

What's the pattern for Oregon and Washington? The weather pattern that brought cold weather to Minnesota brought unseasonably warm weather to the Pacific Northwest, so if they see the same baby boom, it's more of a holiday thing than a cold winter thing.
