Pass level winds:            calm, westerly

Barometer:                    1020mb’s and slowly rising

The Forecast: A tad warmer today with a chance of an afternoon shower or two.  Clear mornings with an afternoon cloud show will be the pattern through the weekend.

Long Range: This fickle weather will continue through next week with weak systems moving through every few days or so.  Freezing levels will remain above Pass levels, so no snow expected.  

  

The Science:  Weak mid-level ridging will provide for mostly dry conditions for the mountains.  Diurnal temperature swings will drive good convection for afternoon cloud development.
