For the forecast, low pressure will continue to bring cool unsettled weather to the area over the weekend in a Northesterly flow aloft. The airmass is moist and unstable so precipitation amounts are a challenge. Unsettled weather for Sunday and Monday with flurries expected both days with a freezing level at or just above surface.  A brief high pressure will build over the area for Tuesday with sunny skies. A very weak front is forecasted to reach the coast on Thursday in a warm Southerly flow. Guesstimates: 10-15 cm by Sunday morning, 2-4 cm by Monday morning, 0-2 cm by Tuesday morning.

    Upper level trough for the weekend.

    Flow into Monday.

   A bit more snow for today with cooler temperatures.

    Unsettled for Sunday with a mix of sun, cloud, and flurries.
