A bit warmer with a slight inversion, but at -14 with a 40 KPH wind the wind chill index is -26.

    As of 07:00 Hrs this am we have clear skies and unlimited visibility.


Another sunny one, with some cloud development, as a warm front moves onto the coast for later today in a Southerly flow by tonight. This morning the surface flow will be primarily Easterly with cold temperatures. The  front will arrive tonight and we could see light snow if everything aligns, or flurries if the high sends the low South. At this time its hard to nail it down, but a strong Westley flow aloft is likely. Being optimistic I think the low will have enough energy to bring moderate/heavy snowfall to the area for Friday into Saturday, as per the European Model. Temperatures will warm up on Friday/Saturday but the FL should still remain below surface. A chance for the FL to rise slightly on Saturday with the passage of the warm front, but we will still see snow to the valley. Moisture, cold temperatures--almost a perfect scenario.  We may see some very light flurries on Sunday. High meets low scenario in which the strongest survives.  Still some uncertainty to what will exactly transpire, more as we plod along. Guesstimates: 4-6 cm by Friday morning, 15-25 cm by Saturday morning, 20-30 cm by Sunday--lots of number shuffling & certain this may change again before tomorrows post.

    This morning, high pressure over Southern BC.

    Looking like a storm day Friday on the 500 MB model.

    Low could line up for the perfect scenario.. 850 MB Friday.

    If everything aligns for Saturday we could see some heavy snowfall.

    Looking clear and cold Monday into Tuesday.
