    20 cm of snow on the Horstman Glacier Sunday morning.                                      Jeff Symes Pic

    Friday afternoon, eventually the sun did come out. 4.2 mm of rain fell from 00:00hrs-06:00 Hrs.

    Moisture plume slipped Southeast later Friday afternoon.

    Overcast with moisture laden clouds Saturday morning.

    Snowed into the tree line early Saturday morning.


    Saturday morning, still cloud and showers in the area in the morning, cleared by the afternoon.


    West bowl on Whistler Mountain Saturday afternoon. We had 1.8 mm of precipitation at 660 M.

    Sunday morning September 27, 2015--Stratus cloud layer moved in overnight.

    Mix of sun and cloud Sunday afternoon.

    Full moon was Sunday night.  Info on the Blood Moon



Weather Observations for September 28, 2015: taken at 06:00 Hours.

2180 meters     +3, Winds were 10-15 KPH from the E
1835 meters     +3, Winds were 5-10 KPH from the E
1650 meters     +3, Relative Humidity 84%
  660 meters     +2, Valley Temp, Max Temp Yesterday was +17.4

    As of 07:00 Hours this am we have clear skies and unlimited visibility. A slight inversion.

    Satellite image from this morning, some stratus cloud lingering along the coast.



For the forecast, weak upper level ridge will remain in the area until Tuesday, bringing clear skies and warm daytime temperatures with an East to Northeast offshore flow. A weak dry upper level trough will bring cooler temperatures and some cloud to the area for Wednesday into Friday. Will depend on what happens with the deep upper level low in the North Pacific.  The models continue to have inconsistencies and with a slit flow pattern there is a possibility of continued sunny weather and warm daytime temperatures. At least it looks dry into Friday. Confidence in the models is low at this point so we will have to take it as it comes. Will have a forecast for next weekend on Friday.


    High pressure with offshore flow will maintain sunny warm conditions.

    Looking sunny for today.


    Offshore flow continuing into Tuesday.


    Low looks like it may push onshore.


    Confidence in the ECMWF, NAM and GFS are inconsistent--will depend on the high and low.



    Could see some cloud on Thursday with the low sending some cloud into the area.

    No confidence in the models for next weekend. Will depend on what the upper level low does.
