Forecast Discussion: Current Conditions as of 1 PM on Friday: PM-2.5 concentrations are currently inside the good range this Friday afternoon with a brisk northwesterly wind providing ample mixing across the region. High pressure will build from the west later today, turning the flow to more southerly and a lighter breeze with PM-2.5 concentrations expected to return to more moderate levels. Temperatures over the weekend should climb to levels slightly above normal before beginning a transition to colder than normal temperatures by late next week. *** Saturday’s Forecast: A mix of sun and clouds will allow for temperatures to climb into the low to mid 40s on Saturday with a light breeze out of the south. PM-2.5 concentrations will begin the day in the higher end of the good range, but some locations will see values climb into the moderate range over the course of the day. As will be the general theme of the forecast period, conditions do not appear to be favorable for widespread good air quality nor at the same time do they appear to be favorable to cause concern for elevated concentrations. *** Sunday’s Forecast: Similar conditions as Saturday will continue into Sunday with the only difference being slightly warmer temperatures due to expected increase in sunshine. PM-2.5 concentrations will once again remain in the higher end of the good range for some sites, but sit at low to mid moderate levels elsewhere. Winds will again be a light southerly breeze with temperatures Sunday reaching closer to the mid 40s than Saturday. *** Monday’s Forecast: After a dry and pleasant weekend, the potential for a return of precipitation will increase on Monday and continue into Tuesday. While there remains much uncertainty as to how much may fall in the form of snow and if there will even be great enough intensity for it to accumulate, what is certain is that air quality conditions will likely remain unchanged. A strong low pressure system well to our south and east and another more to the north and west over the Great Lakes will leave us sandwiched in between the systems for a period of time on Monday. This area tends to see sinking air due to the systems on either side which if that becomes the case would likely limit much snowfall from occurring as well as allow for moderate PM-2.5 concentrations to continue. I don’t think this would limit all precipitation, so the potential for accumulating snow will need to be monitored over the course of the weekend as the event develops. Temperatures will likely be limited more to the mid 30s under overcast skies. *** Extended Forecast: Chances for snow showers will continue into Tuesday, along with moderate air quality conditions despite an increase in winds. The trend to colder than normal conditions will continue on Tuesday as highs will struggle to reach the freezing mark. Brisk westerly flow into Wednesday will finally help to return PM-2.5 concentrations back to the good range, but will also continue to filter the colder air mass into the region. Breezy conditions will continue through the end of the week with temperatures peaking in the upper 20s to low 30s each day. Good air quality will continue through at least Friday. --- Roble
