FORECAST:

Low to our south will brush by with overcast skies in a Southerly flow aloft. Likely see some breaks. The frontal boundary is just South of here so chance it might drift North with some flurries. Thinking its staying South so going with a dry day. The FL is below surface and will likely go up to 1200 m with daytime heating, dropping back below surface tonight. A weak front for Saturday as the low moves down the coast. Periods of light snow with some sunny breaks in the pm. Dries out on Sunday with some snow flurries and overcast skies. A vigorous front arrives Sunday night with strong winds, moderate-heavy precipitation and warmer temps. (Hopefully FL Lower than 1500m). More on the FL as we get closer, it may change. Front pushes through Monday with active weather for most of the day, drying out Monday night. Tuesday looks nice with some brief ridging and dry conditions. Some evening flurries as the next front arrives Wednesday. Went beyond comfort zone, time will tell. Model discrepancies. Guesstimates: 0-trace by Saturday am, 2-5 cm by Sunday am, 12-18 cm by Monday am above 1200 m, 18-22 cm by Tuesday am above 1500 m, 1-3 cm by Wednesday am.
