Delays are expected at Raliegh-Durham International (RDU) today.
High Probability of Delays Between 8:00 AM on 2/21 and 8:00 AM on 2/21
During this time period the airport expects to experience mist which will cause a high likelihood that flights will experience delays.
Here is a look at what the forecast conditions are and what is required for normal operation:
| Normal | Forecast | |
| Conditions | None | Mist, rain |
| Visibility | Greater than 2 | 10 |
| Wind | Less than 11.8 MPH | 7.1 MPH |
| Clouds | Higher than 1,000 | Overcast at 1,500 |
While the weather conditions should be good enough to land aircraft the low visibility caused by these weather conditions will probably require ATC to slow down the flow of traffic to ensure that aircraft arrive safely.
Medium Probability of Delays Between 8:00 AM on 2/21 AND 11:00 AM on 2/21
During this time period the airport expects to experience thunderstorms which will cause a medium likelihood that flights will experience delays.
Thunderstorms are potentially deadly for aircraft, mainly because of the unpredictable and severe winds that are associated with these storms. That wind causes a significant risk to landing aircraft and so airports will typically close during thunderstorms.
Lightning can also cause a hazard to ground staff, so airports may decide to stop servicing aircraft on the ground during these storms and for a period of time after they have passed.
Here is a look at what the forecast conditions are and what is required for normal operation:
| Normal | Forecast | |
| Conditions | None | Thunderstorms, rain |
| Visibility | Greater than 2 | 0.5 |
| Wind | Less than 11.8 MPH | 5.9 MPH |
| Clouds | Higher than 1,000 | Overcast at 4,000 |
The following flights may be impacted:
| Departure Airport | Airline | Flight | Departure Time | Arrival Time |
| KDTW | Delta Air Lines | DL 2708 | 06:56 | 09:00 |
| KORD | Air New Zealand | NZ 2791 | 06:00 | 09:00 |

| KORD | United Airlines | UA 5824 | 06:00 | 09:00 |

High Probability of Delays Between 11:00 AM on 2/21 and 3:00 PM on 2/21
During this time period the airport expects to experience low clouds and mist which will cause a high likelihood that flights will experience delays.
Here is a look at what the forecast conditions are and what is required for normal operation:
| Normal | Forecast | |
| Conditions | None | Mist, rain |
| Visibility | Greater than 2 | 1.5 |
| Wind | Less than 11.8 MPH | 5.9 MPH |
| Clouds | Higher than 1,000 | Overcast at 300 |
While the weather conditions should be good enough to land aircraft the low visibility caused by these weather conditions will probably require ATC to slow down the flow of traffic to ensure that aircraft arrive safely.
High Probability of Delays Between 3:00 PM on 2/21 and 6:00 PM on 2/21
During this time period the airport expects to experience mist which will cause a high likelihood that flights will experience delays.
Here is a look at what the forecast conditions are and what is required for normal operation:
| Normal | Forecast | |
| Conditions | None | Mist, rain |
| Visibility | Greater than 2 | 10 |
| Wind | Less than 11.8 MPH | 4.7 MPH |
| Clouds | Higher than 1,000 | Overcast at 800 |
While the weather conditions should be good enough to land aircraft the low visibility caused by these weather conditions will probably require ATC to slow down the flow of traffic to ensure that aircraft arrive safely.
Low Probability of Delays Between 6:00 PM on 2/21 and 12:00 AM on 1/1
During this time period the airport expects to experience rain in the forecast which will cause a low likelihood that flights will experience delays.
Here is a look at what the forecast conditions are and what is required for normal operation:
| Normal | Forecast | |
| Conditions | None | Rain |
| Visibility | Greater than 2 | 10 |
| Wind | Less than 11.8 MPH | 4.7 MPH |
| Clouds | Higher than 1,000 | Overcast at 1,500 |
Depending on the severity of the rain this may have no impact on your flight. Light rain is typically OK to take off and land through, but heavier rain may be something that your pilot decides to wait out on the ground.
