  660 meters       +3, Valley Temp, Max Temp Yesterday was +7.4.

   As of 07:00 Hours, we have overcast skies and unlimited visibility.

For the forecast, the weak warm front slowly moved onshore last night and should dissipate by this evening. Southwest flow aloft will bring light rain to the area for today with the freezing level hovering around 2000 meters and possible accumulations of 3-5 mm of precipitation by this evening with a rising freezing level (2500 M ?) by Friday morning. Friday morning will usher in a stronger warm front with moderate to heavy precipitation, cooling too 1800 meters Friday evening with unsettled weather. Unfortunately the precip amounts for this time frame are increasing and we could receive up to 20-30 mm of rain. Enough already!! Lets hope for a better outcome!  The broad upper ridge begins to dominate the pattern on Saturday, strengthening into Sunday with unsettled conditions.  A Northerly flow will bring dry and cool conditions with sunny skies Monday through Wednesday. Freezing levels will likely drop to the valley floor by Monday evening. We may get 5-8 cm of snow above 2000 meters for Friday morning and an additional 15-18 cm above 2100 meters by Saturday morning. As it cools we may get a few centimetres by Saturday morning at 1650 meters. 




    Moisture came into the mountains last night.

    Light showers can be expected for most of the day.

    Front will affect the area on Friday.

    High pressure begins to build on Saturday.

                                Jet Stream begins to migrate North.


    High pushes the low to the North for Sunny Conditions and cooler temperatures.
