Forecast Discussion: Current Conditions as of 1 PM on Friday: A weak area of high pressure has allowed for much more sun to shine across the region than the wet and dreary conditions earlier this week. Dry conditions will continue through the weekend, though a cold front on Saturday will bring a period of unseasonably cool temperatures. *** Saturday’s Forecast: A cold front will swing through the region early on Saturday, turning the flow to more westerly and rather brisk. Temperatures will struggle to climb much higher than the low to mid 50s, which is a little bit below normal for the middle of October. The brisk flow will mix the air quite well, leading to PM 2.5 concentrations sitting well within the good range for the day. *** Sunday’s Forecast: Brisk conditions will continue along with unseasonable temperatures and good air quality. Some clearing is expected during the afternoon, but temperatures will have a hard time reaching the 50 degree mark with the brisk winds continuing to filter in colder air to the region. PM 2.5 concentrations will again remain well inside the good range for the day. A weak ridge of high pressure will slide to our south Sunday evening, helping to calm the winds a bit. *** Monday’s Forecast: Temperatures will dip low into the 30s Sunday night into Monday if the winds are able to calm enough under mostly clear skies. With upper level winds turning to more southwesterly, we may see a little bit of warmer air moving in aloft over a slightly colder air mass at the surface. This could lead to PM 2.5 concentrations climbing back into the moderate range Monday morning. Some mixing during the afternoon hours may bring those morning concentrations back closer to the good range, but the southwesterly breeze may help keep some locations just inside the moderate range. Another disturbance will approach the region on Tuesday. *** Extended Forecast: There is still some uncertainty as to the timing of this next storm system, but Tuesday appears to be the most likely day for it to arrive. This system will bring at least a chance for some showers, not nearly as much in the way of precipitation as we had seen this past week. PM 2.5 concentrations may remain in the moderate range for at least a few locations early on Tuesday, but another shot of unseasonably cool air behind this system will return the brisk winds and good air quality for the middle portion of the week. High pressure looks to build from the west for the end of the week and into next weekend. --- Roble
