Time and Day: 0930 Friday
The
Snapshot: Snow showers will gradually taper off today, westerly
winds with +- 4500’ freezing levels. Dry tonight and tomorrow.
The
Science: With some
luck we will squeeze a few more inches of snow out of these showers. A weak
convergence zone aimed at Stevens Pass will keep snow showers falling through
mid to late afternoon. Another weak cold
front drops in on Sunday for another light rainy/snowy mix episode.
4-7day
Long Range: Long range models are struggling to agree on next week’s
forecast, so confidence is low. With
that said, the week will start out dry and warm with a few weak systems possible
making their way through the region during the middle of next week. No significant snow is expected for all of
next week.
