Time and Day: 0730 Monday
The Snapshot: Clear skies over Steven Pass this morning
with sunshine slated for the day. Mostly
dry tomorrow with increasing clouds and rain for Wednesday and Thursday.
The Science: High
pressure centered over the inland NW will provide clear, dry and warm weather
for the mountains today and most of tomorrow.
Clouds begin to
roll in tomorrow as a strong warm front tracks up from the south. Models
have the leading edge of the rain band entering the mountains around midnight
tomorrow with rain expected for most of the day on Wednesday. Freezing levels west
of the crest are 8000’ with 5000’ freezing levels to the east. There will be east flow associated with this
storm but no cold air available for snow. An
inch or more of rain will be likely on Wednesday.
The Long Range: The rain diminishes on Thursday with a weak
cold front expected to swing through on
Friday. At this point in the game, just
light snow showers are expected on Friday and Saturday.
