Good Morning Sailors,
Although the ridge of high pressure shifted eastward yesterday, it didn't completely clear the area, leaving us with lighter winds than expected. We're also starting out today with less wind than I expected. Gradients are in place, with Portland to The Dalles measuring in at 09, but the wind just isn't hitting the water yet. High clouds are a concern now as well, but they will clear as the day goes on, allowing wind to build on the river.
As clouds clear and temperatures build in the desert, gradients increase. Winds climb to the 17-21 range by noon, and into the low twenties by mid afternoon. Upper level flow is a bit northerly, so we may see better winds at The Hood, Mosier and Rowena than at the Hatchery. It's worth keeping an open mind about where to sail today if you'd like to avoid gusty conditions.
Marine influence increases tomorrow. Unfortunately, so does the impact of an upper level low (yes, already) parked off Vancouver Island, despite all the "no parking" signs posted in the offshore waters. Without the assistance of offshore high pressure, winds struggle to climb past the 17-21 range. Cooler temperatures will make for better mountain biking, however, and let me tell you, Post Canyon is in epic shape!
Tuesday looks like it could be a great day. We still won't have high pressure offshore, but we'll have a deep marine layer (to contribute to the thermal component of the wind) and we'll have a passing front. The combination of the two will send desert winds into the 24-28 range late in the day.
I believe it's time for me to drink some coffee now. I need it. This early upper level low is making me sad (I want to sail my 3.7, damnit), and the only solution is a caffeine serotonin boost.
Have a great day on the water!
