Delays are expected at Philadelphia International (PHL) today.
High Probability of Delays Between 3:00 PM on 2/20 and 5:00 PM on 2/20
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, snow |
| Visibility | Greater than 2 | 10 |
| Wind | Less than 11.8 MPH | 8.2 MPH |
| Clouds | Higher than 1,000 | Overcast at 2,000 |
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 5:00 PM on 2/20 and 9:00 PM on 2/20
During this time period the airport expects to experience mist which will cause a high likelihood that flights will experience delays.

| Visibility | Greater than 2 | 1.0 |
| Wind | Less than 11.8 MPH | 8.2 MPH |
| Clouds | Higher than 1,000 | Overcast at 900 |
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 9:00 PM on 2/20 AND 12:00 AM on 2/21
During this time period the airport expects to experience low clouds and snow which will cause a medium likelihood that flights will experience delays.
Snow causes many issues at airports, reducing the visibility for landing aircraft and making the runway slippery. Airports that typically see a lot of snow will have the resources to clean up, but heavy snowstorms may cause extended delays.
Here is a look at what the forecast conditions are and what is required for normal operation:
| Normal | Forecast | |
| Conditions | None | Snow |
| Visibility | Greater than 2 | 10 |
| Wind | Less than 11.8 MPH | 8.2 MPH |
| Clouds | Higher than 1,000 | Overcast at 800 |
