- Quiet Weather into Next Week

Surface high pressure and dry north flow will dominate the weather over the next week with no rain expected until the end of next week. An Omega block will be across North America with Lower Michigan in between an upper high across central Canada and troughing across eastern Canada into the NE CONUS.

Weak frontal passages occur tonight and again Sunday night but there is no moisture available until return flow sets up by next Thursday. A cold front sagging down from the northwest could focus showers and perhaps a thunderstorm Thursday night into Saturday before it clears Lower Michigan and high pressure builds in behind it.
