Summer Solstice

posted in: Michigan Weather Forecast | 9

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.

For what it’s worth, the CFS weeklies are now above average temps all the way to August. And the latest CPC also shows a warm July and a warm July, August, September period.

As for how “hot” this summer will be. The latest JMA Weeklies (Japan) and the latest CFSv2 weeklies both indicate a very warm to hot end of June and start of July but a cool down for mid-July. That cool down would not surprise me at all.

Let’s all welcome summer. May this be a nice and warm one for all of us. One of the unusual items this year (and in the last 3 years) is the lack of thunderstorms and of course the lack of severe weather. The Grand Rapids National Weather Service has issued only 10 warnings total in 2018. The G.R. Office covers 23 counties from Mason Co. down to Van Buren Co. east to Clare Co. and Jackson Co. That is almost one third of lower Michigan. Here in Kent county’s 872 square miles there has only been one report of any… Read more »
