Forecast Discussion: Current Conditions as of 1 PM on Thursday: Temperatures have struggled to reach the 30 degree mark across most of the area with breezy conditions and scattered snow showers. The coldest air mass of the season has arrived and will stay until the next disturbance moves in sometime late in the weekend to early Monday. *** Friday's Forecast: Breezy and cold conditions on Friday will help temperatures stay near or just below the 30 degree mark, but also will provide ample mixing for some good air quality. The cold and dry air mass along with the breezy conditions will allow for PM-2.5 concentrations to stay well inside the good range. Similar to Thursday, we will likely see scattered lake effect snow showers across the region. *** Extended Outlook: Winds will still be breezy to start the day on Saturday, but should calm a bit by the afternoon as high pressure builds over the region. Good air quality will continue with a clean air mass in place and continual mixing over most of the day. Temperatures again will only reach the upper 20s to low 30s for highs. Winds will turn to more of a southerly breeze on Sunday as the high pressure slides to our east. Even with the southerly flow, we will not see temperatures rebound much with highs likely to only reach the mid-30s. PM-2.5 concentrations will be in the good range early in the day, but may approach low moderate levels by evening as a disturbance approaches from the west. The current projected track of this system should bring some precipitation, currently appearing to be in the form of a cold rain, for most of the region. Temperatures may briefly push into the 40s on Monday, dependent on the track of the system, before another shot of colder air moves in behind the system. Air quality conditions will quickly improve once again as this system moves through Monday into Tuesday. --- Roble
