Forecast Discussion: Current Conditions: Clouds and areas of fog continue to linger across the region this Wednesday afternoon. Very light winds are resulting in fine particulate concentrations in the moderate range. Low level moisture will slowly retreat over the next 24 hours, allowing for the return of some sunshine Thursday. Moderate levels of PM will continue as there will be only limited mixing. Tonight, expect some clearing to occur, but also areas of fog. PM2.5 levels will move well into the moderate range overnight. Lows mainly in the lower to middle 50s. *** Thursday's forecast: High pressure will allow for some sunshine to return on Thursday. It may very well turn out to be the best day of the week weatherwise as the mercury moves into the middle 70s. While fine particulate matter may decrease some late in the day, higher levels in the morning will lead to moderate averages for the day. Partly cloudy and mild Thursday night with lows in the middle and upper 50s. *** Extended forecast: A strong cold front will approach the area from the Ohio valley late Friday, and rain and a thunderstorm is possible late Friday into Friday night. Overall averages of fine particulate should be in the moderate range once again due to high morning concentrations. Levels of PM will drop late Friday with the arrival of the rain and stronger winds. Much cooler air will then sweep into the region Saturday into the day Sunday with temperatures on Saturday not getting out of the middle and upper 50s on a brisk west to northwest wind. PM concentrations will improve to the good range over the weekend. Rain showers cannot be ruled out in the northern parts of the area Saturday afternoon. Partly to mostly sunny with a gusty breeze Sunday as temperatures move close to 60. A series of weather systems will then move southeastward from the Great Lakes early next week, bringing more clouds than sunshine, periodic bouts of showers, but good air quality as the lower atmosphere will be well mixed.---McAuliffe
