- Quiet Weather through the Weekend
The dry weather pattern continues this week under upper and surface ridging. The next chance for rain is not until early next week. A slowly progressive pattern sees the ridge being flattened by northern stream troughing early next week with a cold front bringing showers while slowly pushing south through the Great Lakes.
- Height falls with showers then cooler next week
There are some indications the front could stall near Lower Michigan with a surface low moving along it for Tuesday or Wednesday. Upper troughing follows with the potential for sharply colder temperatures for the rest of next week.
Aviation
