When an air mass from the Gulf of Mexico pushes northwards into an area that has been under the influence of a Canadian air mass, the conditions in Pittsburgh would typically experience significant changes.
Current Conditions:
- Temperature: Temperatures would likely start to rise as the warm, moist air from the Gulf of Mexico replaces the cold, dry Canadian air.
- Humidity: Humidity levels would increase, leading to a more humid and muggy feel.
- Cloud Cover: You might see an increase in cloud cover as the warm, moist air interacts with the cooler air in the area.
- Precipitation: There could be a chance of rain, especially if the warm, moist air is forced to rise over any remaining cool air, which could lead to cloud formation and precipitation.
Conditions in Two or Three Days:
- Temperature: Continued warming is expected. Pittsburgh could experience highs typical of early summer, possibly in the 70s or 80s°F (20s to 30s°C), depending on the strength of the Gulf air mass.
- Weather Systems: Depending on other atmospheric conditions, there could be a risk of thunderstorms, especially in the afternoons or evenings as the heat builds up.
- Humidity: The higher humidity will likely persist, contributing to a feeling of mugginess.
- Air Quality: The influx of moisture and warmth may lead to worsening air quality, especially if there are local pollutants.
In summary, Pittsburgh is transitioning from cooler, dryer conditions typical of a Canadian air mass to warmer, more humid conditions influenced by the Gulf of Mexico. Weather will likely become more unstable, with an increased chance of precipitation and thunderstorms in the coming days.
