Time and Day: 0630
Tuesday
The Snapshot: Partly cloudy today with snow tomorrow and
Thursday.
The Science: Today will be
mostly dry under weakening high pressure.
Clouds thicken tonight as a progressive system prepares to track through
the PNW tomorrow. This system will likely
be a nice snow producer for Stevens Pass.
Snow diminishes Thursday as another weak high-pressure
ridge builds.
The Long Range: Things
get interesting on Friday as a strong warm front with an SW fetch of moisture begins to form. Moderate rain/snow mix could be setting up
for Saturday. The weekend it is still a bit far out, so stay tuned as the long range
details get more dependable.
