FORECAST:
The warm upper air mass that moved through last night was replaced with a weak cold front in a Southwesterly flow aloft. Unfortunatley most of the precipitation went South. Today we can expect light snowfall with overcast windy conditions as a deep surface trough pushes throug our zone. Saturday is looking unsettled as an upper ridge begins to build in the area. The FL will likely hover around surface. Sunday is unsettled with more cloud than breaks. The FL will likely spike at around 1200 meters. The ridge strengthens Monday/Tuesday with a warm air mass in the area. The FL could spike to as high as 2300 meters. Looks like a Pineapple express coming our way for Wednesday. Guesstimates: 10-15 cm by Saturday morning, Trace -1 cm for Sunday morning.
Light snow for today with overcast skies.
Cold front passes through Friday with cooler temperatures and light snow.
Unsettled Saturday with the chance of some isolated flurries.
Cooler temperatures Saturday with a Westerly Flow.
Sunday will be unsettled.
High builds for Monday.
