A storm in the Gulf of Alaska is currently affecting the northwest. Energy will split as it moves west, with a piece of energy traveling south along the coast and another piece skirting to our north. We will be spared the coldest part of the approaching storm as most of the cold air slides north and east of us.
Tomorrow should be another nice day before clouds build ahead of the approaching storm later in the day. The wave to our southwest is forecast to eject some energy over our area late Wednesday night or early Thursday leading to some accumulating snows by Thursday afternoon in the 2-4” range.
Precipitation should let up later Thursday before a cold front approaches from the north late in the day. It does not appear there will be good overrunning around the front as the flow aloft is very weak in the vicinity of this split system. Generally unsettled weather with light snow of around 1-3” is expected.
Another wave approaches from the northwest early Saturday, and this one appears to have a slight split to it as well. Slightly heavier snowfall is expected with this cool push of air, though amounts are still expected to be light and in the range of 2-4” each day of the weekend. Temperatures should continue to cool through Sunday morning continuing the light snowfall.
Skies don’t look to clear until late Monday as we remain in cool and moist northwest flow. A nice Tuesday before another approaching storm influences our area mid-week.
