- 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.
