    Mon Dec 4: Interesting N wind wave day

    Considering a flight to SF and return on Monday. Unlike the previous two flights, the winds are much lighter:

    Level ....Dec 4 '17 ...Mar 31 '17 ...May 1 '16
    18,000 ..42 kt ........60 kt ...........75 kt
    14,000 ..36 kt .......est. 55 kt ......50 kt
    10,000 ..30 kt ........55 kt ...........25 kt
    .6,000 ...20 kt ........35 kt ...........20 kt

    Unlike Mar 31 when there was around 30 degrees direction variance, this Monday's direction is 010 at all levels, + or - a few degrees:

    What I like about Monday is the linear increase in wind, but at 1/3 less at the cruise altitudes of 10-18K. Let's see what the RASP sez on Fri eve.

    Hey Kemp,

    Thanks for the heads up!

    Unfortunately, I have a meeting late Monday morning when I cannot move.

    Have fun!

    Kemp, Thanks also from me, and for the invite.
    I have to be home on Tuesday.
    Besides. I have no suitable flying machine.

    The williams RASP shows nice goat and St. Helena wave.



    The new 7 day rasp is much more optimistic. Except -- not at Mt. Tam. It seems to be much weaker south as well, with weaker winds. A chance to head north?
