Abundant cloud cover and some passing showers joined forces to keep us on the cool side today. Given that it’s been warm nonstop lately, a cooler day isn’t too hard to handle. Highs were right around 60, and they won’t fall too far overnight.
Through Tonight: We stay fairly socked in with clouds this evening and into the night. There could be some breaks as well, just don’t expect them to be too numerous or long lasting. There’s the outside shot of a sprinkle, too. Lows end up ranging across the 50s, from about 51 to 58 in the coolest suburbs to urban warm spots. Winds are light and variable.

Tomorrow (Thursday): We’ll need to keep an eye on showers and thunderstorms that are currently near the Great Lakes for the morning commute. There is some hint they’ll make it here, but a better hint they’ll fall apart to our north. Otherwise, warmth and higher humidity are back. There’s some question as to when skies turn clearer, and that could affect temperatures a bit. In the coolest and cloudiest scenario, we might get stuck in the 70s. If sun breaks through early and intensely, above 80 seems more likely. For now, I’m going to go with “near” 80. Expect a bit of a movement one way or another in Thursday morning’s forecast update! Winds are from the south and southwest around 5 to 10 mph.
Pollen update: Tree pollen is VERY HIGH at 1555.91 grains/cubic meter. Other allergens are LOW.
Susak Kosisky of the U.S. Army Centralized Allergen Extract Lab also detailed the huge pollen counts over the weekend into early this week:
While March tree pollen counts were below average for most of the month with the cooler wet weather, April counts have soared. Daily average counts for the second week in April are well above average. The high temperatures in the 80s and plenty of sunshine really brought the tree pollen out this past weekend. Counts reached greater than 2500 grains/cubic meter of air for both Saturday and Sunday.
The count for April 16 might well be the highest daily count this 2017 tree pollen season at 2678.62 grains/cubic meter. This daily count was the highest in the last four years.
