Forecast Discussion: Current Conditions: Unseasonably mild and moist air continues to stream northward into the region this Christmas Eve. Periods of rain will continue into tonight, with perhaps a thunderstorm as a strong cold front moves through later on. While some locations continue to have PM concentrations in the moderate zone, improvements to the good range are likely this afternoon into tonight as precipitation and wind both increase. Temperatures will slowly rise into the 50s this afternoon into tonight as well. *** Thursday's forecast: Precipitation will quickly come to an end early Christmas morning as a cold front moves off to the east. Winds will then increase and become gusty through the day, leading to low levels of fine particulate. High temperatures close to 50 degrees will be reached in the late morning prior to falling off some in the afternoon. Clear to partly cloudy Christmas night with winds diminishing. Turning colder with the mercury falling close to 30. *** Friday's forecast: High pressure will provide a tranquil day for Friday with sunshine and a few clouds. Lighter winds shifting into the southwest will result in increasing values of PM, perhaps to the lower moderate range. Afternoon temperatures recovering to the upper 40s. *** Saturday's forecast: Light southwesterly winds will continue for the day Saturday with high pressure shifting off the east coast. With the southwest flow, PM concentrations will continue in the moderate range. With enough sunshine, we could see temperatures rise into the lower 50s. *** Sunday's forecast: A weak cold front will approach the region for Sunday. A little cooler with perhaps a rain or snow shower at any time. Highs will reach the lower 40s. Mixing will likely be limited in the vicinity of the front, so PM2.5 will remain in the moderate zone. *** Monday's forecast: A cold front will be to our south on Monday, but a wave of low pressure may develop along it in the Tennessee valley and move northeastward by late in the day. There may be enough cold air in place for snow to develop later Monday into Monday night. Enough of a north to northeast wind should prevail for fine particulate to improve to the good range. *** Extended forecast: A trend to colder weather may be in the offing for the long range period as a series of low pressure systems moving across the eastern part of the nation act to bring down progressively colder air from Canada on their backsides. Below normal temperatures will likely start off the new year with any storm systems passing through increasingly likely to track to the south and east of us and produce more in the way of frozen precipitation. The upside to this is with more of our air being of Canadian origin, good air quality is more likely.---McAuliffe
