Forecast Discussion: Current conditions: At 2 p.m. EST this Tuesday afternoon, the lower atmosphere is starting to mix out across the area, with fine particulate levels continuing to decrease. In spite of this, we will still have moderate PM2.5 levels overall today. Mild air is also moving into the area on southerly winds, with temperatures close to 60 degrees. A cold front will affect the area tonight with showers, and temperatures will fall back to around 40 degrees later on. *** Wednesday's forecast: Mostly cloudy for Wednesday with a couple of rain showers still possible. Temperatures will only move into the middle 40s during the afternoon, and mixing will be adequate to bring PM2.5 concentrations down to low levels. High pressure will mean some clearing for the area Wednesday night as temperatures drop close to freezing. *** Extended forecast: A very mild period is in store for the long range, with temperatures well above normal. A couple of low pressure areas will affect us and track to the west during this period. The first system affects us Friday, and then the other comes along late Sunday into Sunday night. Light winds will cause fine particulate to increase to moderate by later Thursday into Saturday, then heavier rainfall and brisk south winds mean good air quality Sunday into Monday.---McAuliffe
