Rains to the south as summer begins; quiet weather tomorrow and Saturday

Happy Summer Solstice!

This is the astronomical start of summer:

The meteorological start of summer is June 1, because most meteorologists refer to the three warmest months (June, July and August) as summer.

Feel free to celebrate both starts to summer!

By the way, you can find sunrise and sunset times for many locations for an entire year at the U.S. Naval Observatory site.

For example, here are 2018 sunrise and sunset times for Minneapolis.

Too much rain

Turn off the rain-maker!

Many southwestern and south-central Minnesota counties have seen generous rains in the past 24 hours, and the rain continues over far southern Minnesota this Thursday morning.  The rain should gradually become more scattered later this afternoon, and eventually move out of Minnesota.

NOAA’s Advanced Hydrologic Prediction Service shows shows where the heaviest rains fell in the 24 hours ending at 7 a.m. today:

NOAA/USGS 24 hour rainfall ending 7 a.m. June 21

You can see some three-to-five-inch amounts in the far southwest.

When you look at the 7-day rainfall totals ending at 7 a.m. today, it’s impressive that so many parts of Minnesota and Wisconsin have seen a lot of rain:

NOAA/USGS 7 day rainfall ending 7 a.m. June 21
