A strong cold front brings light snow late Wednesday into Wednesday night, then strong and gusty winds with a few snow showers are likely Thursday. Here are the forecast details: *** Wednesday’s forecast: Turning out mostly cloudy Wednesday with high temperatures only in the middle 30s. A little snow will occur during the afternoon. PM2.5 will lower late in the day and at night as south winds increase but overall averages of this pollutant will remain in the high good range. *** Extended forecast: Windy and cold Thursday with a few snow showers. Strong vertical and horizontal mixing will promote good air quality as high temperatures do not rise above the upper 20s. Snow accumulations may reach an inch or two. High pressure then provides dry conditions but below normal temperatures Friday and Saturday. The air will warm a little Sunday as winds shift into a southerly direction as the high moves off the east coast. Good air quality will continue Friday into Saturday, then may turn moderate by Sunday with milder and more moist air making inroads into the region.---McAuliffe
