12/14/2009 Weather
Short term: Several strong frontals system will bring snow to the Pass tonight and then again tomorrow night.
Long-term: Active weather will continue through the week. A warmer system with freezing levels rising above pass level is expected by the weekend. Long-term models differ on the precipitation associated with the weekend weather so I will leave that for later in the week.
24 hour forecast starting at noon on Monday

temperatures (F): 4000’ Low: 14 High: 32 5000’ Low: 12 High: 30 |

TRENDS AND TIMING
Precipitation: Snow showers will persist today ahead of fast approaching frontal system. Look for snow to ramp up tonight as the system moves through -should have most of the snow on the ground by 7am. Snow will quickly turn to shower tomorrow in preparation for the next system expected to move in tomorrow night.
Freezing levels: East flow will help hold freezing levels low over the crest through the night. Freezing levels will rise to 4000’ after 7 am tomorrow and hover between 4000’ and 5000’ for the day. Snow levels should stay below pass level for most of the day.
Winds: East flow at the surface will persist through the day. Winds will slowly shift S then SW through the night. SW flow will continue through most of the week. jdm
