Forecast Discussion: Current Conditions as of 1 PM on Tuesday: Rain showers have moved into the region early this afternoon as a cold front approaches from the west. Unseasonably cold temperatures will return for Wednesday, but good air quality will prevail. *** Wednesday’s Forecast: A dry and unseasonably cold air mass will move in over the region for Wednesday. Brisk northwesterly flow will usher in this clean air mass, providing a day of good air quality. PM 2.5 concentrations will fall well inside the good range as the front pushes east during the early hours of Wednesday. Sunshine will return by the afternoon, but the brisk flow will limit just how warm the sun may feel. Highs on Wednesday will be held to the mid to upper 50s, roughly ten degrees below normal. *** Extended Forecast: High pressure will be more overhead on Thursday, creating not as brisk of flow with mostly sunny skies. PM 2.5 levels may rebound slightly when compared to values of Wednesday, but will still remain inside the good range. Temperatures will return to near normal values with highs expected to reach the mid 60s. The northwesterly breeze will become even calmer Thursday night before turning more southerly early Friday morning. The next chance for showers will come late in the day on Friday. With the southerly flow, we will see warmer air with increasing moisture push northward just ahead of the arrival of this precipitation. PM 2.5 concentrations will climb closer to the moderate range for Friday, but it appears as if cleaner air will return with brisk flow once again on Saturday/Sunday. The next several days look to have mostly good air quality with Friday having the greatest probability for a brief period of more moderate conditions. --- Roble
