Here is a more detailed both CONUS and for Michigan, October Climate Summary.

By waiting until the 8th, I can get the maps from NCEI (National Center for Environmental Information). I have added graphs from xmACIS for the daily temperature and precipitation plus I have the monthly climate summary from Grand Rapids and Gaylord.

Enjoy the warm weather this week because it will get much colder next week and parts of Michigan may even see their first snowfalls by Tuesday. Happy Halloween!

This shows our transition point from warmer to cooler weather.

The weather over the next two weeks will feature some warm and dry weather as well as cold and wet weather. Mostly it will be warm dry over the western CONUS into next week. Over the eastern CONUS it will mostly be cooler and wet. A significant warm up may follow over the eastern CONUS by the middle of next week.

Typical of fall we will see a warm up, then it will rain and get cooler, only to warm up by early next week.  Then it will get wet and cooler once again.

Expect the wet and cool weather over Northern Midwest into New England, including the Great Lakes, to persist into early next week. An impressively large blocking upper-level high, over central Canada will keep the storm track over the northern CONUS into early next week. It will also allow a subtropical system to track along the Gulf Coast over the next few days.

After having 4 days with highs in the 80s over Southwest Michigan, to start October, a series of cold fronts will lower our high temperatures by Saturday into the lower 50s. The cooler temperatures are expected to last into the middle of next week before another slow warm up begins. Widespread rainfall, mostly between a quarter and half an inch will occur Thursday as the front moves through. Lake effect rain showers are expected into early next week.

It will fell like fall by Friday morning and that chilly and showery weather my last into Tuesday morning before the system is far enough to east to allow for some clearing. It will remain chilly Tuesday into Wednesday before a warm up starts by Thursday of next week.

Here is an updated report on the storms on August 24, 2023. As it turned out there were 1 EF-1 tornado in Southwest Michigan, and EF-2 tornado in South Central Michigan and 6 tornadoes, 1 EF-0 and 5 EF-1’s in the Detriot area. I updated some of my slides for the event.

I updated my story about the severe storms since the NWS has now reported 8 tornadoes in Michigan on the 24th of August. The strongest was an EF-2 near Webbrvillle

It was a HOT JULY over most of the CONTINENTAL UNITED STATES but that was not the case for the Upper Midwest and Great Lakes.

As promised I have posted the national images of July 2023. The short story is it was the 7th warmest and 45th wettest for the CONUS. In Michigan it was the 58th warmest and 5th wettest on record.

Heavy Rain was forecast for yesterday afternoon into mid morning today. The slides below show the what actually happened.

We forecast heavy rain between I-94 and I-96 and that is exactly what did happen. The heaviest rainfall report showed 4.50 inches in Middleville, most of that area had between 1″ and 3″ of rain from the event.
