20 degrees? Seriously?
I know that down South, the blood's a little thinner, but you get the colder days right?
I'm in the Twin Cities in MN. Our school rule for elementary is you are outside UNLESS the air temp is 0 degrees OR the windchill is -10 degrees.
at 20 degrees, these kids would be inside for probably4-5 months of the school year.
Maybe you are upset at the lack of notification? At the same time, if you are dressing a child for 32 degree weather, they should be wearing about the same stuff for 20 degree weather.
I'd love to be in the South, but we're not.

Yes, I am upset with the lack of notification. In response to your "if you are dressing a child for 32 degree weather, they should be wearing about the same stuff for 20 degree weather", perhaps you don't understand. When I took her to school on Monday, there was snow on the ground and it was below 32 degrees. I figured it wasn't a huge deal that she did not have her hat and gloves since they wouldn't be going outside and I drop her off and pick her up from school. Because I wasn't notified in the change in policy, it was a big deal. She was really cold on that playground for 30 minutes, 3 times that day. Still no notification went out on Monday, only some parents were notified yesterday. Keep in mind that if you don't normally send your kid out in cold weather and you are used to the school policy of 32 degrees (including windchill), you may not even have a true heavy coat for your child. My kid does have a heavy coat, but I know of others who don't.
Funny thing is the Principal at the Middle school refused to change his policy. It is and always was 32 degrees, so the older kids get to stay inside and the little Kindergarteners thru 2nd have to go outside.

Anyway, I was just curious to see what it is around the country. I can actually understand sending the kids out below 32 degrees, I know it won't cause sickness, etc... I do wish the school had been better about changing policy and notifying parents so that they can be better prepared.
