Wet & Windy

February 14, 2007

Snapshot_24Nice slug of subtropical moisture sitting offshore and stretching well off to the southwest.  This means a good 24-36 hours of  heavy rain in the mountains (Timberline and Mt. Hood Meadows are already above freezing at 5,500’+), and light-moderate rain here in the lowlands.  The strong orographic component to the flow should squeeze more than 3 times the valley rainfall totals down over the mountains.  As I pointed out at 11pm, this is good news in February because reservoirs begin holding back water here in the Northwest.   The break between the warm wet system Thursday and a much colder system Sunday has narrowed a bit.  It’s definitely a one day warmup for Saturday.  Onshore flow and 850mb temps to -4 Sunday should bring snow down to 2,000′.  This ushers in a cool & wet pattern for next week.  So make your outdoor plans for Saturday because every other day of the next 7 looks at least showery, if not quite wet…Mark
