Here we are the first day of summer though it seems it actually started over a month ago with the temperatures and humidity being as they have been. The summer solstice (or estival solstice), also known as midsummer, occurs when a planet’s rotational axis, or geographical pole on either its Northern or its Southern Hemisphere, is most greatly inclined toward the star that it orbits. On the summer solstice, Earth’s maximum axial tilt toward the Sun is 23.44°. (Likewise, the Sun’s declination from the celestial equator is 23.44°.) This happens twice each year (once in each hemisphere), when the Sun reaches its highest position in the sky as seen from the North or South Pole.
A slow moving low pressure system centered over Iowa will lift into the Southern Great Lakes region over the next few days. This will result in an unsettled weather pattern developing. Temperatures will likely end up below normal over the next couple of days as well. As I write this there are some sprinkles moving into extreme southwest Michigan – the heavier rain is located in Indiana moving south to north.
Some high res models are suggesting the showers could become numerous towards Kalamazoo. Will increase probability of rain for southern parts of the CWA…mainly for this afternoon. The thunder risk looks low through this evening…but some elevated instability is shown to move in later tonight. Will therefore start to mention a risk for a few storms then…and keep that risk into Saturday with a pesky low around.
