FORECAST:

Weakening upper level ridge will bring unsettled weather today to Whistler in a South Westerly flow aloft. Onshore flow should make for a cooler day compared to the weekend warm temperatures with some cloud in the mix. Similar day on Tuesday as the ridge continues to shift East we will likely see an increase in cloud by Tuesday evening. A frontal band will eventually push in on Wednesday with an increase in cloud cover and some light precipitation by Wednesday night into Thursday morning. Models differ for Thursday and that's a ways off, how much precipitation on Thursday and Friday is the question? Good chance several trough's could push through but the high may ease back in with some influence. A soaker both days or perhaps a bit of reprieve either Thursday or Friday. Weak high pressure is forecasted to return by Saturday into Sunday. Guesstimates: 0 mm by Tuesday am, 0 mm by Wednesday am, 5-25 mm by  Thursday am, 20-25 mm by Friday am, 0-trace mm by Saturday am, 0 mm by Sunday am.

     High pressure maintains its position over Whistler with onshore flow, slightly cooler for Monday.





    Fronts along the coast.

         High maintains its grip on Tuesday but slowly moving to the East.





      Low moves closer with mostly cloudy skies for Wednesday.



  .  Low will send several troughs our way Thursday and Friday.





    High will likely rebound a bit more than this by Saturday. May not? Likely unsettled.

    Unsettled for Sunday. Mix of sun and cloud.
