What is the temperature and dew point spread reported for Portage (CYPG)?

The temperature and dew point spread is a crucial factor in aviation weather reports, as it helps in assessing the likelihood of fog formation and cloud development. A spread of 4 degrees indicates a relatively narrow difference between the temperature and dew point, which suggests that the air is quite humid. This condition typically raises awareness for pilots regarding potential visibility issues due to fog, especially if the temperature approaches the dew point.

When the spread is low, as with a 4-degree difference, it is easier for the temperature to drop to the dew point, which can lead to condensation and possibly lower visibility conditions. This understanding is vital for flight planning and safety assessments.

In this case, the reported spread for Portage (CYPG) being 4 degrees signifies the importance of maintaining situational awareness regarding weather changes as they might influence flight operations and safety.
