FORECAST DISCUSSION
After a mostly cloudy and wet week, conditions are shaping up to be a nice late-summer type of weekend. After a weak low-pressure system exits the area on Friday, we will see a drying out period with low humidity and warming temperatures.
I expect those warming temperatures to prevail through the mid-levels of the atmosphere with high-pressure dominating the region and the lack of moisture keeping most of the area dry and clear. Afternoon high temperatures are expected in the upper-70’s and low-80’s under sunny skies with nighttime temperatures under clear skies in the mid-50’s. Indications are that this pattern will last through the middle part of next week.
In terms of Air Quality, I am not anticipating any issues during this tranquil period and AQI levels should range between Good and Moderate through the forecast period.
EXTENDED FORECAST:
Air Quality is expected to remain Good to Low Moderate entering the upcoming work week.
