Forecast Discussion: Current Conditions: As of 2 PM on Friday, a mix of sun and clouds persist across the region as a new high pressure system builds in over the Great Lakes region. The clockwise circulation around this high has steered our flow out of the northwest. As a result, temperatures have struggled to make their way out of the 50s. The northwesterly advection of air is rather clean (with origins from Canada). As a result, this air mass is rather low in precursor pollutants for ozone. Therefore, levels continue to hover in the good category. Over the weekend, we will see a rise in ozone closer to the good / moderate threshold on Sunday before more cloud cover limits ozone formation late in the period. Here are the details... *** The Weekend Forecast: Over the weekend, expect abundant sunshine to prevail over the region as a result of the an area of high pressure moving in over the northern Mid-Atlantic. On Memorial Day, this high will move offshore. On the backside of this high, the winds will steer out of the south, resulting in warmer, more humid conditions building in. This will also increase the probability of showers and thunderstorms as we roll into Monday into Tuesday. The sunshine over the weekend will not only lead to temperatures extending into the 70s but ozone near the good / moderate threshold by Sunday. As more moisture moves in on Monday and Tuesday, cloud cover will become more of a factor, limiting ozone formation to the good category. --Nolan
