Forecast Discussion: Current Conditions: A large area of high pressure sprawled out across the Ohio valley is sending drier air in our direction this Friday afternoon. The sun has even managed to poke through the clouds at times. This high will move slowly east-northeastward over the weekend, and provide dry weather and lighter winds through Sunday. With less mixing expected to occur, fine particulate levels will rise over the weekend. The weather will then turn more unsettled by the middle of next week as a powerhouse storm is slated to affect the area. So, for tonight, expect a clear to partly cloudy sky. A little colder than recent nights with lows in the middle to upper 20s. Fine particulate will also be on the increase late tonight. *** Saturday's forecast: Morning cloudiness will yield to some afternoon sunshine on Saturday. With mixing limited, expect fine particulate to be in the moderate range during the day on average. High temperatures will reach close to 40 in the afternoon. Clear to partly cloudy again Saturday night with lows in the middle 20s. Temperature inversions and calm winds will send PM well into the moderate range. *** Sunday's forecast: Periods of clouds and sunshine Sunday with high pressure still in control of the weather. High temperatures may reach the lower 40s with continued moderate air quality. *** Monday's forecast: An area of low pressure forming along the North Carolina coast will move north-northeastward for Monday, and cause clouds to increase. Moderate air quality will continue with light east to southeast winds. A little ice and rain is possible Monday night into Tuesday morning as a cold air damming situation sets up across the region. Lows Monday night near freezing. *** Extended forecast: A little ice and rain to start Tuesday, then precipitation should turn to all rain by the afternoon. A major storm will then develop in the Ohio valley for Christmas Eve, intensifying as it moves into the Great Lakes. A strong cold front will move through Wednesday evening, with decent rainfall expected out ahead of it. Turning very windy late Wednesday night into Christmas Day, but with rapid drying. Moderate air quality will continue on Tuesday, but PM levels will then improve to the good range Wednesday into Christmas with strong and gusty westerly winds.---McAuliffe
