Last Daily Ozone Forecast for 2008

Thursday, September 18, 2008

Short-Term Discussion: Clouds have cleared out nicely across the region today, and with a generous amount of sunshine, temperatures have rebounded into the lower and middle 70s. Overall air quality has been good.

Expect just a few clouds tonight. A weak cold front will come into the area from the Great Lakes later on tonight or Thursday morning, but this lacks any moisture and will not produce any rain. Low temperatures will bottom out close to 50. Tomorrow, north to northwest winds will increase behind the front. This will keep ozone and fine particulate matter levels in the code GREEN range.

Tomorrow night, the sky will be mostly clear and winds will drop off, leading to a fairly chilly night. Lows will drop down into the middle 40s.

Extended: Any precipitation is going to be difficult to come by over the next several days. High pressure will continue to control the weather across the state. Friday will be the coolest day, with high temperatures only reaching into the middle 60s, but then a bit of a warmup is in store for the weekend. Air quality should remain good into Saturday, perhaps reaching lower code YELLOW levels by Sunday for particulates.
