Forecast Discussion: Current conditions: Broken cloudiness with brisk northwesterly winds are accompanying winter like conditions this Friday afternoon. The only upside is the brisk low level flow has kept fine particulate levels low today. Mostly moonlit and rather cold overnight with temperatures falling back to near 20 degrees. A developing inversion may bring higher particulate matter concentrations. *** Saturday's forecast: Sunshine through mid and high level clouds Saturday with temperatures only recovering just past the 40 degree mark. Although winds increase a little in the afternoon, near calm morning winds will push daily PM2.5 averages into the moderate range. *** Sunday's forecast: Clouds will limit sunshine Sunday, but the afternoon will be milder as temperatures move close to the 50 degree mark. Light southwest winds will permit particles to remain in the moderate range. *** Monday's forecast: Turning out mostly cloudy Monday out ahead of the next weather system. Winds will remain light enough to allow for moderate PM concentrations most of the day. Light rain is possible by the evening. Turning colder later Monday night with rain turning to snow as a strong Arctic cold front passes. *** Tuesday's forecast: Windy and winter like on Tuesday with snow tapering to snow showers by the afternoon. Temperatures will remain near 30 degrees with wind chills in the teens. Total snow accumulation from Monday night to Tuesday afternoon possibly reaching an inch or two. Fine particulate will be well down in the good range. *** Extended forecast: Very cold conditions with temperatures well below normal remain with us Wednesday, before temperatures moderate some on Thursday. Air quality will remain good.---McAuliffe
