    Very cloudy early Friday May 22, 2015.

    High overcast over the valley early Friday morning.

    Convective cloud development by mid morning.

    Cumulus nimbus developed later in the day with some isolated showers.

    Dark clouds around 20:00 Hours.

    Breaks to the Southwest just before sunset.

Weather Observations for May 23, 2015: taken at 05:00 Hours.

2180 meters      +6, Winds were 0-10 KPH from the NNW
1835 meters      +7, Winds were 0-5 KPH from the NNE
1650 meters      +6, No new snow, Base 75 cm, relative humidity is 95%

  660 meters    +12, Valley Temp, Max Temp Yesterday was +25.7, 0.5 mm recorded on Friday.

    As of 06:00 Hours we have high overcast, a stratus layer and unlimited visibility.


For the forecast, high pressure offshore will maintain moderate to strong onshore flow into next week. The weak low pressure to the Southeast will continue to bring a chance of showers into the mountains. The pattern will be slightly different than the past week where it will likely be cloudier in the mornings breaking in the afternoons with the chance of rain later in the day into the night time hours. The marine stratus layer has moved onshore and will likely lift later this morning with day time heating.

    Still significant moisture to our South and East.

    Will be mostly cloudy today.

    High pressure North and West low Southeast.

Weather Observations for May 22, 2015: taken at 06:00 Hours.

2180 meters      +5, Winds were 10-20 KPH from the NW
1835 meters      +7, Winds were 0-5 KPH from the E
1650 meters      +6, No new snow, Base 90 cm, relative humidity is 100%

  660 meters    +11, Valley Temp, Max Temp Yesterday was +27.6.

    As of 07:00 Hours this am we have mostly overcast skies and unlimited visibility.


For the forecast, moderate to strong onshore flow will bring mostly cloudy skies to our area for today into Saturday as an upper low remains stationary over our zone.  Still a chance of a few sunny breaks but the moist unstable air mass should produce showers with the threat of thundershowers later in the day. The unsettled pattern will continue into next week as a weak upper level trough develops over the Pacific Northwest. There may be a change in the cycle, with cloudy mornings and sunny breaks in the afternoon.

     Onshore flow will bring mostly cloudy skies.

    Low will be in our zone over the weekend.

      Saturday looks like a repeat of Friday.

For the forecast, the persistent pattern will bring mostly cloudy skies this morning with convective cloud development by this afternoon and the chance of some isolated showers later in the day. The air mass may become a little more unstable later in the day for the chance of some thunder showers. Friday may be the wetter of the next few days with showers later in the day.  Low to moderate onshore flow will continue into early next week with little change in the forecast as the weak upper level trough remains in our zone. Unsettled until at least Wednesday.

    Same pattern different day.

      High pressure is expanding in the Pacific.

   Flow yesterday and today.

   Stratus Cloud along the coast.

    Stronger onshore flow for Friday could bring slightly more precipitation than the daily average.
