The above map is the forecast of total rainfall from the Weather Prediction Center for Monday thru Friday of this week. Summer shower and storm activity can vary greatly from one town to the next. For example, take last Saturday AM, when parts of Kalamazoo County got 4 1/2″ of rain, while 10 miles away less than 1/2″ fell. The WPC says that on average, much of W. Michigan will see only 1/10 to 1/2″ of rain through Friday.
To break it down…we were dry on Monday. We have a chance of a shower or t-shower this Tue. PM. The chance will be least in the lakeshore counties (10%) and highest over toward the Thumb (60%). Wednesday should be dry. We’ll have about a 40% chance of a shower or storm Thursday PM/night (a little less than 50/50 at this point). Then, we have a chance of a shower or storm at some point next weekend. High temperatures this week will be mostly in the low-mid 80s – 70s at Lake Michigan.
This week is on average the warmest week of the year. This week we have an average high temperature of 83 and average low temperature of 63 in Gr. Rapids. On Monday both the high temp. (83) and low temp. (63) were exactly average for the date.
The map above also shows a continuation of the wet pattern across the Southern U.S. from Texas to the Carolinas…and look at the rain (mostly PM showers and storms) in Arizona and the Southern Rockies.
We have a layer of smoke in the atmosphere, around 8,000 to 12,000 feet above the ground. It’s high enough that you shouldn’t smell any smoke at ground level. The smoke is from wildfires, in Ontario and in the western U.S. and Canada. The smoke can give an orange tint to the moon at night.
The smoke can also give a grayish-white color to the sky during the day. You can see that in the picture above that was taken by Steve Hager at Morrison Lake Sunday morning (7/18/21).
ALSO: Record of catastrophic floods in Germany. Lightning near Tucson AZ. Wildfire east of Sacramento CA. Waterspouts off the coast of Italy. Waterfall in New York State (not Niagara). Nice time lapse of a thunderstorm that was 100 miles away. Two tropical storms in the Western Pacific…and two in the Eastern Pacific. This looks like a blizzard, but it’s really a very windy hailstorm. Smoke billows up from CA wildfire. Lightning hits the Empire St. Building in NYC. “According to the National Weather Service, the Empire State Building is hit by lightning an average of 25 times per year.” Boston MA has had over 5 times average.rainfall this month.
