Forecast:

A warm strong Pacific front will bring heavy precipitation and strong gusty winds to our area in a Southwest > Southerly flow aloft. The freezing level as of 07:00 hrs this am was at around 2000 meters. Lets hope it stays there so the alpine can get a needed dumping. Several bands will push through into Tuesday night with moderate precipitation and slightly cooler temps. A weak ridge will build for Wednesday with unsettled weather and a dropping FL. Unsettled pattern for Thursday into Friday with some snow flurries, clouds, and the occasional break. Freezing level will drop into the valley hopefully by Friday night. Long range is looking much cooler.
