Time and Day: 10:00 am Wednesday
The Snapshot: The mountains are draped in a soppy blanket this morning. The radar has heavy rain falling along the
western slopes with the higher elevations (+ 7000) getting some snow. The rain will begin to shift showers tomorrow
with intermittent rain showers persisting in the mountains through the weekend.
The Science: Today’s heavy rain is being powered by a low-pressure
system tracking up from the south. The
center of the low is currently just off the Oregon coast and is expected to
track north into southern Canada over the next 12hrs. A long
SW fetch of moisture is in tow which is
the main source of the rain today. The rain should turn to showers tomorrow as the
storm heads into the Canadian Coastal Mountains tonight.
The Long Range: The
atmosphere will remain unstable, keeping the threat of rain in the discussion
through the weekend. Next week will start out mostly dry with a
cooler air mass in the early development stages for mid to late next week.
