FORECAST:

High pressure in a Northerly flow for today with slightly colder temperatures. We should see a slight rise in the temperatures for Thursday as the low has a bit of influence on the strong arctic high pressure. The low off the coast will slowly affect our area by Thursday evening with overcast skies and light snowfall into Friday morning. The modified arctic front is rather stationary and is likely to deflect the low South. We should see light cold snow fall on Friday with unsettled conditions for Saturday. The air mass will remain relatively dry over the weekend with ideal snow making temperatures. Will try to post an update this afternoon if it looks like a change in this pattern is likely. Guesstimates: 4-6 cm by Friday morning, 5-10 cm by Saturday morning. Models are inconsistent so guesstimating is fairly difficult, those #'s could easily change.  Looks like the high pressure will be here for a while with the occasional episode of some cold light snow, possibly sunny and cold for early next week:(

    High pressure maintains strength for Wednesday into Thursday.

    Slow moving low moves in for Thursday night but barely nudging the high Eastward.

    Low off the coast could easily bring the brunt of the precipitation South.

The European model has the high winning this battle.
