    WX ALERT: Wed. June 22

    Charts are indicating that for the Mendocino's up to Spokane, WA, there is strong heating and OD. Comparing this day to the last super day (April 21, 2009) we have positives of stronger heating by 4C along the Goat to Crater Lake route and 10-20% greater humidity:

    but with slightly higher pressure aloft. This is a day to try a Crater lake and return. FNX is thinking of a 1000km O&R. Clouds should start early (10a) but the max bases are likely lower than April 21, 2009 at say 12-13,000 ft. around Yolla. As reference, on April 21 FNX saw 15,300 ft. near Scott Valley. Let's keep watching.

    The Cal model says I cannot fly, but I'll be keeping an eye on the thread. Please keep us posted!

    The wage slave model looks pretty crap too. Sink everywhere.

    Tuesday update. Of course, the model is drying out, so the clouds will be sparse. Not a record day, but still plan to fly. Will report.

    Anxiously awaiting the soaring report.

    Flew (commercial) from SFO to JAX last night and actually got some sleep! Awakened a few times to moonlight on high cloud formations, eerie, but beautiful. It's hot here, 97 degrees, flat bottomed cloud streets everywhere. No thunderstorms - yet!

    A very interesting day. I flew with Simon, the 19 year old WSC intern from Germany:

    This is his first time in the States, so please give him a warm welcome. He's here to late July. Rex nominated him as dual XC candidate, plus that he was on-site made it convenient.

    We launched at 10:23a into a blue sky. On tow we saw our first shred of cu towards Black Butte. Off tow at Goat, we worked 3 knots to 8500, then max glide to St. John, and on towards the shreds. The forecast had dried out, so no record attempts, just wanted to see how far north we could get. After grinding around on the plateau west of Alder Springs, we got high enough to reach Yolla. Curiously, there were few to no clouds on Yolla the whole day. By this time it was clear the clouds were due to convergence. Jim Darke was also flying about an hour behind, wisely.....

    On the T15-16 ridge, we idled under clouds but were losing hright. Simon suggested that we get out from under the clouds and go to the ridge. As soon as we did that, we hit smooth steady 4 knots to 12.5, here's the video (wait for the video to load):

    We also saw our first shred of cloud towards Weaverville, so we set off at a conservative 60 knots towards the ridge just N of that town. Once on that ridge, we could only maintain ridgetop height. The ClearNav winds were showing up to 24 knots from the west, but only at certain parts of the ridge, otherwise it was 8 knots. Very odd. After a few seconds of appreciation for the Alp-like scenery, I struggled to get a breakaway thermal. After about 20 minutes we finally got something to 8500, but that was barely enough I thought to get to the clouds east of us that then ran all the way home. To the north the clouds looked great, but they started 20 miles away. With the help of an unexpected blue thermal in the middle of the valley 5 miles E of Weaverville, we connected with the clouds. It was then straightforward to fly home (wait for the video to load):

    It was hot and humid yet the clouds were not of a flat bottom variety. Late in the day the clouds east of Weaverville blew up in the only storm for a hundred miles around.

    Simon enjoyed his time and got to see some of the area. Let's hope we have some more high(er) based days.

    Oh, here is the rh chart for the day, very dry!

    Great posting, Kemp - looked like a beautiful day. Glad you were able to take advantage of it! The video's captured the wispy nature of the clouds. They looked like they were the type to form and dissipate pretty quickly. That was a nice flight on a "dry" day.

    Glad you were able to make the flight with Simon.

    Welcome to WSC, Simon! Wishing you many wonderful flights during your time here!
