Ice Storm Warnings are currently in place across Central and Northeastern Oklahoma right across the I-44 corridor and puts Oklahoma City and Tulsa right in the bullseye for a significant ice storm. The thought of an ice storm becoming more likely happened last night as computer models shown the cold air moving into the area was much colder than previous thought and with a major storm system moving into the area this evening that will produce heavy precipitation, the fear has grown that a major to crippling ice storm will likely play out in Central Oklahoma.

Short range high resolution computer models are showing a very significant accumulation of ice will be possible right along the I-44 corridor from Lawton to Tulsa. This includes: Oklahoma City, Moore, Norman, Chickasha, Tulsa, Stroud, Edmond. and Shawnee, Oklahoma. It is possible that a few areas could see over an inch of ice accumulation which will likely cause some significant damage to trees and power lines, and perhaps roofs to buildings. Roads will be very slick and likely impassable by 11pm CDT tonight. Most areas will likely see ice accumulations from .25 to .5 inch outside of the I-44 corridors. Precipitation will likely begin just after 5pm across the Oklahoma City vicinity. When the precipitation starts, it will likely fall in the form of ice as temperatures are hovering in the upper 20s this afternoon and evening. As the night will wear on, we will see an intense band of freezing rain and perhaps thunderstorms move across the I-44 corridor which will produce significant icing very quickly. This will likely occur between Midnight and 4am early Saturday morning.
Impacts from this ice storm could potentially rival the big ice storm that impacted Oklahoma City back in 2007 that brought down many trees and power lines across the city. Please prepare for a significant ice storm and take precautions on the road after sunset tonight. We can expect sporadic power outages sometime after midnight tonight across the city and more numerous power outages as the night wears on. Folks across Moore/Norman and surrounding areas of the Metro, this means you as well! Please Prepare NOW! We are also seeing travel delays at the Will Rodgers Airport and will likely see more cancellations of flights as the night wears on.
High pressure has moved off to the east and has warmer air moving north across the Southern Plains including Oklahoma. Just a week ago, we had quite the snow/ice pack on the ground as far south as Dallas, TX. This week we will be warming up into the 60s and 70s across the state! We can expect this warmer weather to carry on until Thursday when another strong cold front will knock the temperatures below average and give us the shot for some winter precipitation for the weekend! Just another roller coaster ride of Oklahoma Weather!
Rain showers and maybe a thunderstorm across the eastern half of Oklahoma today will be likely as a shortwave disturbance makes its way across the state. We had a wave of precipitation last night that gave us some light rain and even light freezing rain across extreme NE Oklahoma and that has moved into the colder air over Missouri that produce some travel problems if you are heading northeast out of I-44 to St. Louis today. Another wave of showers will move across Southern and Eastern Oklahoma this afternoon. Areas across extreme Southern Oklahoma could hear a rumble of thunder or two as instability is modest at best to support isolated thunderstorms.
