Operations at the grandly named George Bush Houston Intercontinental Airport are being affected today by snow, which is expected to accumulate to about an inch.
[UPDATE 6.30 pm Central time: Ice is setting in and IAH is a mess. A third of today's 1,554 arrivals and departures have been canceled, according to FlightStats.com
That means operations won't return to normal for a day or more.]
Expressjet accounted for more than half of the cancellations, by the way.
