Current Conditions at 3 p.m. EST Monday afternoon: Brisk west-southwest winds are sending mild air into the region with low fine particle pollution (PM2.5) values. However, an inversion developing overnight will result in another particle increase. Milder than normal air will remain with us through Wednesday with windy and much colder conditions arriving later this week. Here are the forecast details: *** Tuesday’s forecast: PM2.5 will be highest Tuesday morning due to an inversion with this breaking in the mid-morning, leading to lower concentrations by afternoon. Daily average values for PM2.5 will remain in the good range. *** Extended forecast: A strong cold front approaching the state Wednesday from the Midwest will result in showers and thunderstorms with brisk southwest winds creating strong enough mixing to maintain air quality inside the good range. A bit of snow is even possible Wednesday night with temperatures plummeting into the middle 30s. A weak disturbance will result in a rain shower Friday, with milder air making a comeback over the weekend. The next strong cold front sweeps through Sunday/Sunday night, followed by another cooldown early next week. Air quality Thursday and Friday will remain in the good range.---McAuliffe
