FORECAST:

Ridging will continue to bring cold unsettled conditions for today in a Northerly flow aloft with a SE surface flow. A surface trough off the coast and too our South may send some cloud into the area this morning, but it should dissipate by the afternoon. It was snowing in Vancouver this am. Tuesday will be mostly sunny with the coldest temperatures of the week. Slightly warmer on Wednesday with some convective clouds in the afternoon. The next frontal band should move on shore for Thursday with more pow on the way!! We could get 30-50 cm by Friday morning but more on that as we get closer. Guesstimates: Trace possible today, will depend on how close the surface trough can push our way.

    Northerly flow with some moisture close by, SW flow over Vancouver.

    Moist over Vancouver but clear over Whistler as of 06:00 Hrs.

    Were on the good side in this model. Snowing in Vancouver this am.

    Later in the day it still looks clear..

    Tuesday is looking mostly sunny, could be a cold one!!
