- Quiet Weather This Week

An Omega block develops this week as an upper trough along the West Coast cuts off into an upper low and troughing persists in in eastern Canada extending into the NW CONUS. In between the two is an upper high over central Canada. The Great Lakes region will see dry northwest flow with Gulf moisture largely absent except for a chance of showers on Wednesday along a cold front.

Lack of deep moisture should keep QPF light on Wednesday except for isolated heavier amounts in scattered diurnally-enhanced thunderstorms attending the front during the afternoon into early evening.
