FORECAST:

Stratus cloud pushed in early this morning with a weak upper ridge today into Tuesday in a Northwest flow aloft. Unsettled today with a mix of sun and cloud, not sure how long it will take to break up the stratus layer.  Ridge still in place on Tuesday with unsettled weather again with cloud spilling in from the low to the North. Ridge pushed out on Wednesday evening with the chance of a shower. Periods of light rain expected on Thursday with the brunt of the moisture from the low arriving Friday into Sunday. Models are not aligned for the weekend so difficult to determine exactly how much moisture is on its way. Favouring the European model which has laid out a wet weekend, but we all know that might change depending on the Aleutian Low.  Guesstimates: 0 mm by Tuesday am, 0 mm Wednesday am, 0-trace by Thursday am, 30-45 mm by Friday am, 20-30 mm by Saturday am, 10-20 mm by Sunday am.

     High still lingering, unsettled for today.





     Fronts along the coast.


       High still hanging in there on Tuesday.





      Low has some influence on Wednesday with unsettled weather.

      Low pushes in late Wednesday with chance of some showers into Thursday. Wet Friday into Sunday.


      Low will continue to send moisture our way on Saturday.

      More rain on Sunday, as the low continues to affect our zone.
