Time and Day: 0700 Wednesday
The Snapshot:
I hope you are catching the sunrise this
morning with the beautiful mountain alpenglow. It will
be cold again today with some clouds and light snow moving in tonight. Slow warming and snow developing on Friday
with snow continuing through the weekend.
The Science
Current Observations:
The mercury has dipped to 3
degrees in the base area and 1 degree on the upper mountain this morning. The winds are light and out of the east. This morning’s satellite image has clear
skies over the North Central Cascades and a midlevel stratus layer of clouds to
Northwest.
The Forecast: Today will be much like yesterday with cold
temperatures, sun breaks, and light snow
showers. The general flow will shift NW
tonight with a weak disturbance sliding through. Tomorrow will be another cold and mostly dry
day.
The next storm of interest
arrives Friday afternoon with moderate snow likely. It is a still a bit far out
to get hung up on the details, but for now, the models show 6-10” of snow for
Saturday morning.
The Long Range:
There are several disturbances developing along the British Columbia coastline which will continue to track through
the PNW over the weekend. Freezing
levels will be on the rise but remain well below Pass level. Therefore, expect snow for the entire weekend.
24hr values daily 4am to 4am.
