Forecast Discussion: Current Conditions: As of 2 PM on Monday, partly sunny skies prevail over the region as high pressure continues to control our weather. Right now, the center of the high is situated over the Tennessee and Ohio River regions. The location of the high near our area has allowed the winds to die down. The sunshine this afternoon has forced temperatures into the low 80s. In addition, dewpoint temperatures are hovering in the low to mid 60s. The cloud cover is still helping to hold ozone concentrations in the good category. Expect the moderate air quality to continue into tomorrow as high pressure remains the prominent weather feature over our area. *** Tuesday's Forecast: So for Tuesday, mostly sunny skies will persist throughout the day as the area of high pressure, which was off to our west on Monday, moves off to our east. As a result, our winds should turn more out of the south, resulting in warmer air moving northward into our region. In fact, afternoon temperatures will range in the upper 80s. It will remain humid as well. Ozone concentrations are going to thrive in the sunny and warm environment and reach the moderate range as well. --Nolan
