7 day weather forecast

    Effective as of 4:00 PM Sunday May 30 2021

Explanatory notes:

Showers in the moist and unstable southwesterly flow contracting to the northwestern coastal suburbs and clearing by sunrise tomorrow as the flow becomes more southerly, the cut off low weakens and moves away from the region and a ridge of high pressure begins to build over the region.

The ridge of high pressure over the region leads to fine conditions with pleasant afternoons but cold mornings with good radiational cooling overnight.

Some uncertainty during the weekend this far out with variation between models and model ensembles.
