DALLAS (AP) — Hundreds of flights were canceled Wednesday at the busy Dallas-Fort Worth International Airport while parts of Oklahoma, Missouri and Arkansas braced for an ice storm as wintry weather made its way into the Southern Plains.

The National Weather Service says more than half an inch of ice could accumulate in parts of the Ozarks through Friday morning.

A mix of snow, sleet and freezing rain is expected late this morning through Thursday across the area. Ice amounts of a trace up to half an inch are possible, primarily along and southeast of I-44. Snow and sleet accumulations of a trace up to two inches are also expected. pic.twitter.com/z9xlPkDQeU

Meanwhile, heavy snow is expected in upstate New York and New England later this week with more than 8 inches possible through Saturday morning.

Airlines scrubbed more than 1,000 flights by Wednesday morning, with more than half of the cancellations at the Dallas-Fort Worth airport, where crews began treating runways overnight.

⚠️ Winter weather expected at our airport by the noon hour. If flying from #SGF this afternoon expect delays. Airlines have preemptively canceled about 20% of today’s SGF flight schedule. Sure to check the status of your flight often. #springfieldmo #bransonmo #417land. pic.twitter.com/VsbdK3Exl3
