Time: 1000
The
Snapshot: Today will be mostly dry with a few sprinkles
possible. Rain tomorrow with freezing
levels well above 5000’ can be anticipated. Dreary wet conditions will continue
along the northern Cascade Crest through the middle of the week.
The
Science: A rather
large low pressure system tracking north into central BC is the cause of the wet
warm weather. The jet stream is extremely
fragmented, making for an unorganized storm track, typical for this time of year.
Cooler NW flow develops late Wednesday as high pressure develops off of the California
/ Oregon coast. This high pressure will likely cut off or push and significant moisture north into Canada
over the weekend.
4-7day
Long Range: The week will end under cooler NW. Light rain or
snow showers will continue to be possible through the weekend.
