Mostly sunny today as high pressure moves across the Upper Midwest. Some diurnal cumulus will develop in the afternoon but no rain is expected. Ventilation this morning will initially be poor but quickly improve to excellent as we warm through the later morning hours. With the abundance of sunshine expected for today there is a chance we overachieve on our Min RH forecast. We are currently forecasting Min RHs in the lower 30s but some of the high res guidance is dropping it into the mid 20s. Additionally, we will still have some breezy northwest winds today with gusts in the mid 20s. The most likely time for these higher winds will be between noon and 3PM. .REST OF TODAY...
