Despite a bit more in the way of cloudiness than anticipated, today was quite the winner. In the end, those clouds helped keep temperatures in the very pleasant 70s most spots all day — so, it’s hard to complain about them too much! A magnificent evening, a windows-open type of night, and a glorious Thursday are all ahead.
Through Tonight: Clouds will tend to wane as we lose the heating of the day. We’re mostly clear by sunset if not prior, and then staying that way overnight. With a relatively dry air mass still in place, it’s a cool one. Or, at least cool enough to not need A/C! Lows eventually fall to the mid-and-upper 50s in the coolest suburbs while settling closer to the mid-60s downtown.
Tomorrow (Thursday): Spectacular. The end. Ok, ok… details: Pleasantly cool morning temperatures rise toward highs in the upper 70s and low 80s. All of this under mostly sunny skies. Add in a light breeze swinging around from north to south during the day, and there’ll surely be few grumblings around the region.

Achoo: Weed pollen has reached the HIGH/VERY HIGH range, and just about right on time. As you can see in the graph above, weed pollen typically peaks in September. The main producer is ragweed. According to Susan Kosisky of the U.S. Army Centralized Allergen Extract Lab, “ragweed is a short day plant (SDP) which means that flowering occurs as day light hours decrease.” Additionally, Kosisky stated, “ragweed starts to flower as the day length becomes shorter than 14.5 hours.” Sneezing may be a way of life for some over the next few weeks.
In other pollen news, mold spores are moderate/high, grass pollen is low/moderate, and tree pollen is low.
