Forecast Discussion: Current Conditions: High pressure continues to build into the area this Friday afternoon. A dry and chilly north to northwest flow continues to persist, with fine particulate levels down in the good range for the most part. In spite of sunshine, the mercury is only managing to get into the middle and upper 20s. Rather cold tonight under a mostly clear sky with low temperatures bottoming out close to zero degrees in the colder spots. Fine particulate will also increase to well into the moderate zone overnight with snow cover still present and inversion strength increasing. *** Saturday's forecast: High pressure will begin to move slowly to the east of us for the day on Saturday. PM2.5 levels will start the day in the high moderate range, but the day overall should average in the middle moderate zone. With a fair amount of sunshine, temperatures will recover into the middle and upper 20s. Not as cold Saturday night with lows in the middle teens. PM2.5 concentrations will remain moderate. *** Sunday's forecast: Clouds will increase and thicken during the day Sunday. With warmer air as well as moisture coming in aloft, and with winds very light, fine particulate levels will continue to be elevated, and we will continue to monitor this for the possibility of low code ORANGE levels during the day, but for now, I will go with AQI readings in the upper moderate range. Temperatures will rebound into the lower to middle 30s, with snow possible late Sunday into Sunday night. Snow may mix with sleet and even rain, depending on how much warm air gets in aloft. If precipitation is mostly snow, a few inches of it can accumulate Sunday night into Monday morning. *** Monday's forecast: Precipitation will move off to the east Monday morning, allowing for some afternoon sunshine. Fine particulate levels should fall into at least the lower moderate range late in the day, if not upper good. Highs mostly in the upper 30s. *** Extended forecast: The weather pattern remains active into the middle of next week with another storm slated to move out of the southern Plains. With this one, mostly rain is expected later Tuesday into early Wednesday, and genuinely mild air might even move in on southwesterly winds for a brief time. Moderate air quality is expected most of Tuesday into Wednesday with warmer and more humid conditions. The air will then turn colder Thursday into Friday, but with better air quality.--McAuliffe
