Time and Day: 0930
Thursday
The Snapshot: -8f this morning, add in
the wind chill of 14mph = -30f. Hang in
there, warmer air is on the way. Today
will stay cold, windy and dry.
The Science: A low pressure system developing off the Oregon
coast will push a couple of weather systems southeast along the Columbia River
during the next few days. Therefore,
most of the energy (precipitation) will be south of Stevens Pass. Cool easterly flow will remain intact so the
moisture that does make it to Stevens will be snow. The
weekend is now trending partly sunny and mostly dry.
4-7day Long Range: Long range models are all
over the board on what to expect next week.
Next weeks overall trend is wetter and warmer.
