Forecast highlights
⏩ “Persistence” forecast
Sometimes, you wind up in a stagnant weather pattern where things don’t change much from one day to the next.
When meteorologists make their forecast in these situations, they call it a “persistence” forecast — that is, the current weather is simply persisting with little change from day to day.
If you’re a daily reader, you might now be guessing that this week has been a persistence forecast. And you’d be right.
Temperatures sure aren’t changing much over the next week.
Dew points will become somewhat more humid, as I’ve mentioned other times this week. I still don’t see reason to expect them to become oppressive, though.
And rain? Similar story: Nothing much to report until Monday at the earliest, and probably not really until Tuesday or Wednesday.
The National Blend of Models shows heavy rain well to our west across parts of the Corn Belt, where several inches will be possible in the coming days.
I’m not entirely sure why it’s generating a 1” bullseye just to our west… I assume one or two of the models in the blend are wet and pushing the average up. Right now, I’m discounting that.
📊 Today’s almanac
Normal low/high: 65 / 85
Record low/high: 46 (1989) / 96 (2012)
Sunrise/set: 6:37 a.m. / 8:37 p.m.
🌆 Losing light fast
We have 14 hours of daylight today. As you see right above this line, our sunrise is 6:37 a.m. and sunset is 8:37 p.m.
Back on June 21 — the first day of summer and longest day of the year — the sun came up at 6:03 a.m. and set at 9:04 p.m. Yup, we had 15 hours of daylight that day, which means we’ve now lost a full hour over the past seven weeks.
We’ll lose two minutes and nine seconds of light today compared to yesterday, and that number will keep rising until we reach the fall equinox in September. For about two weeks, we’ll max out at two minutes and 36 seconds lost daily.
After that, the pace of lost daylight will gradually slow down until the winter solstice, when we have nine hours and 20 minutes of daylight.
