Forecast Discussion: Current conditions: Breezy westerly winds along with partly sunny skies have made for rather mild conditions this Wednesday afternoon, with plenty of horizontal ventilation bringing good air quality. A significant change to colder weather will occur over the next 36 hours with the passage of a strong cold front. *** Thursday’s forecast: Showers and a thunderstorm are likely during the day Thursday with the cold front passing during the mid afternoon. With the frontal passage, west to northwesterly winds will increase substantially, and the strong mixing will keep PM2.5 averages rather low. *** Extended forecast: A chilly, gusty wind will continue for Friday in spite of a mostly sunny sky. High pressure building closer may lessen the wind some by Saturday with a good deal of sunshine. Clouds will make a comeback on Easter Sunday out ahead of the next weather system, which could bring rain later Sunday into Sunday night. Good air quality will prevail Friday into the weekend.---McAuliffe
