Blue = winter weather advisories. Pink = winter storm warnings (the more serious condition) as of 6:45am CST. Green = flood advisories.
Currently, there are 30 minute delays at LaGuardia and Philadelphia from the rain moving through those areas. The snow has not yet reached the Chicago airports where no delays are currently reported. That will change later this morning, however.
AccuWeather regional radar at 6:50am shows snow moving toward Chicago and increasing in the Northeast.
I was supposed to change planes in Chicago late this morning and have rerouted myself through Houston to avoid major problems. You can, too, as airline waivers are in effect which allows you to change your trip or reroute at no charge.
