FORECAST:

The upper level trough which produced a nice early season dump to the valley has pushed through with some flurries expected this am in a SouthWesterly flow aloft.  Mostly a dry day until tonight with a more active frontal band arriving in the early am Tuesday with slightly warmer temperatures and light/moderate precipitation. The freezing level is hovering around surface and may go as high as 1000 meters today dropping back to just above surface tonight. Should see a fairly dry day Wednesday with mostly cloudy skies. Another weak frontal band arrives Thursday and Friday. Models are all over the map for the weekend with the European models calling for warm and wet. More on that in Thursdays post. Guesstimates: 5-10 mm by Tuesday am, 18-26 mm by Wednesday am, trace-1 mm by Thursday am, 3-6 mm by Friday am. Made an error , updated amount for Tuesday am (06:00 hrs)

       Dry day today with the low to the Northwest and high to the East. Front arriving tonight.






      SouthWesterly flow aloft today, switching to Westerly tomorrow.


        Deep low will bring a warmish system on Tuesday.






      Weak high Wednesday, could still be dry and cloudy?? Warm air to the South.



      Weak high builds Wednesday.

      Looking like a warm flow could occur by Friday. 



      High strengthens Thursday but could get some power flurries in the mix, changes Thursday night.

      Another frontal band on Friday.
