Forecast Discussion: Current Conditions: As of 2 PM on Thursday, partly cloudy skies prevail over the region as high pressure continues to dominate our weather. Right now, moderate northerly flow is helping to hold temperatures in the mid 60s. PM 2.5 levels continue to hover near the good / moderate threshold across the metro area. Expect air quality levels to creep up and hang near the good / moderate range tomorrow as warmer temperatures build in. *** Friday's Forecast: So for Friday, expect partly cloudy skies to persist again over the region as the area of high pressure, which was over the Great Lakes and steering the northerly flow on Thursday, shifts east and over the New England states. As a result, winds are expected to turn easterly to southeasterly. The more southerly profile of the winds will turn our afternoon temperatures up toward the low 70s. The combination of the increase in temperatures and the increase in low level moisture should help to keep PM 2.5 levels near the good / moderate threshold. --Nolan
